Jinhua Jiandun Industry and Trade Co., Ltd. is a professional door manufacturer and trading company headquartered in Jinhua, Zhejiang Province, China, a region long recognized as one of the country's most dynamic hubs for building materials and hardware production. Our core business covers the design, production, and export of interior doors, exterior doors, wooden doors, steel doors, and fully custom door solutions for buyers around the world. We work with importers, distributors, contractors, project developers, and retail brands who need a stable, factory-direct supply of quality doors at competitive prices. Because we combine manufacturing capability with trading expertise, our clients get the best of both worlds: direct factory pricing and a partner who understands international documentation, shipping, and compliance. Over the years we have refined a production system that balances craftsmanship with industrial efficiency, allowing us to handle both small trial orders and large container-volume programs. Whether you are sourcing a single style of flush door for a residential tower or a mixed catalog of fire-rated and security doors for a commercial project, we can build the program around your specification.

Quality door manufacturing is not simply about cutting panels and hanging hinges; it is about controlling moisture, tolerances, finishes, and hardware so that every unit performs reliably in its final environment. Our factory operates with modern production lines, but we still rely heavily on experienced craftsmen who understand how timber behaves, how steel frames must be reinforced, and how a finish coat should be applied so it lasts for years rather than months. This combination of technology and human skill is what separates a reliable door supplier from a transactional trading company that simply resells whatever the market offers. International buyers increasingly demand traceability, consistent batches, and clear communication, and our structure is designed to deliver exactly that. We also understand that door specifications differ dramatically between markets, from imperial sizing standards in North America to metric systems across Europe, the Middle East, and Southeast Asia. That is why every project begins with a detailed technical conversation rather than a generic price list. You can review our broader company profile on the ABOUT page to see how our factory-direct model and one-stop sourcing approach support overseas customers.

The global door market rewards buyers who work with a partner capable of both volume and flexibility, and our position as a manufacturer-exporter allows us to move quickly when demand shifts. A developer may need one hundred hotel doors with acoustic sealing in a single month, while a distributor may need a mixed container of residential interior doors, exterior entry doors, and matching jambs. Jambs, in particular, are an area where small errors create major installation problems, so we manufacture and inspect frames and jambs alongside the door leaves themselves rather than treating them as an afterthought. Buyers who specialize in premium finishes often ask about distinctive hardware and decorative elements, and our team can advise on options such as a polished gold door handle set that complements dark walnut veneer or a matte black finish. This consultative approach is central to how we work: we are not simply selling doors, we are helping buyers build a product line that sells. The sections below explain who we are, what we produce, how we control quality, and how to start an order with us.

Our first competitive advantage is equipment and expertise. Our production facility is equipped with precision cutting machinery, automated edge-banding systems, press and lamination equipment, and controlled finishing booths that allow us to maintain tight tolerances across long production runs. At the same time, our craftsmen bring years of hands-on experience in joinery, framing, veneer matching, and surface treatment, which matters enormously in a category where a two-millimeter gap or an uneven stain can ruin an otherwise excellent product. Machinery ensures repeatability; craftsmanship ensures the details that buyers notice when a customer opens a door in a showroom. These two forces work together on every production line we operate. Because our staff are involved in both sample development and mass production, problems are identified early, before they become expensive shipping errors. Buyers who visit our factory consistently remark that the workflow is organized and the quality checks are genuinely enforced rather than performed as a formality.

Our second advantage is strict quality control from raw material selection through final inspection. We source timber, MDF substrates, steel sheets, hardware, and coatings from vetted suppliers, and we reject batches that show excessive moisture content, warping, or inconsistent thickness. Moisture control is arguably the single most important factor in wooden door manufacturing, because timber that is too wet when assembled will shrink, crack, and distort once it reaches a dry climate or an air-conditioned building. Every stage, from cutting and framing to sanding, priming, and top-coating, has its own inspection checkpoint with documented results. Final inspection includes dimensional verification, squareness checks, hardware alignment, finish uniformity, and functional testing of locks and hinges. Only doors that pass all checkpoints receive export packing. This disciplined process is why repeat buyers trust us with long-term supply contracts rather than one-off purchases.

Our third advantage is the depth of customization we offer. Durable materials, refined surface treatment, and modern design are baseline expectations in today's market, but buyers also need OEM and ODM support that adapts to their brand, their catalog, and their target retail price point. We can develop new profiles, replicate an existing design from a photograph or sample, adjust core construction for weight or acoustic requirements, and create packaging that carries your own label and barcode system. Project-based customization is equally important, since hotels, hospitals, and schools often need doors that meet specific fire ratings, acoustic values, or accessibility dimensions. We handle these requirements through engineering review rather than guesswork, confirming standards with the client before tooling is set. If you want to see the categories we already produce at scale, our PRODUCTS catalog is a useful starting point for that conversation.

Our interior door range includes solid wood doors, composite doors, flush doors, molded panel doors, and sliding door systems. Solid wood doors appeal to premium residential projects where natural grain and substantial feel are essential selling points, while composite and engineered-core doors offer excellent stability and value for volume housing. Flush doors remain the workhorse of apartments, offices, and hotels because they are clean, modern, and easy to specify in large quantities. Molded doors give buyers an affordable way to introduce traditional panel detailing without the cost of solid timber. Sliding doors, including barn-style and pocket configurations, address space-constrained layouts and are increasingly requested in compact urban developments. Across all these categories we can supply matching jambs, architraves, and hardware so that the finished installation looks unified rather than assembled from mismatched parts. Color and finish options range from natural clear coatings to deep stains, matte lacquers, and high-gloss enamel.

Exterior doors must survive sun, rain, wind, salt air, and temperature swings, so material selection is far more critical than it is for interior products. We manufacture security doors, steel doors, aluminum doors, and weather-resistant entry doors with reinforced frames, multi-point locking systems, and thermal or acoustic insulation where required. Steel entry doors are popular in markets where security is the primary concern, and buyers frequently ask how to prevent the surface corrosion that plagues poorly finished metal doors, the same problem commonly described as garage door rust. The answer lies in proper pretreatment, galvanizing or zinc coating, powder coating thickness, and edge sealing, all of which we control in-house. Aluminum doors offer excellent corrosion resistance and a modern slim profile, making them ideal for coastal projects and contemporary architecture. For clients building integrated smart entry systems, our door slabs and frames can be prepared to accept electronic locks, sensors, and video intercom hardware that connect to a smart garage or home automation hub. This forward compatibility keeps your product line relevant as residential technology continues to advance.

Commercial projects demand documentation as much as they demand product quality, and our project door range is built around that reality. We produce fire-rated doors, hospital doors, hotel doors, office doors, and school doors with the certifications and test reports required by specifiers. Hospital doors often need smooth, easy-clean surfaces, acoustic sealing, and hardware that can be operated with a forearm or elbow in clinical environments. Hotel doors typically prioritize sound insulation, soft-close mechanisms, and a consistent luxury finish across hundreds of identical units. School doors must resist heavy daily use and, in many jurisdictions, meet fire and safety glazing requirements. Office doors increasingly combine glass vision panels with acoustic cores to support both transparency and confidentiality. Because we handle mixed orders, a contractor can source an entire building's door package from one supplier, reducing coordination risk and simplifying logistics.

Customization is where our factory structure pays off most clearly. We can produce doors in non-standard sizes, including oversized entries, arched tops, double-leaf configurations, and slim-profile designs for compact spaces. Finish customization covers RAL and Pantone color matching, wood grain replication, brushed and distressed textures, and specialized coatings for humidity or UV exposure. Hardware customization allows buyers to specify handles, hinges, closers, peepholes, and locking systems, including decorative options such as a gold door lever or a brushed brass pull that defines a premium collection. Packaging can be tailored to your distribution model, from individual retail cartons with printed instructions to heavy-duty export pallets reinforced for long sea voyages. We also support private labeling, branded documentation, and barcoded inventory so that your warehouse team can receive and manage stock efficiently. Every custom program starts with a technical drawing and a physical sample for your approval.

Material selection and moisture control form the foundation of everything we build. Timber is kiln-dried and then acclimatized to the humidity level of our production environment before it enters the assembly line, which prevents the internal stress that causes doors to cup or crack after installation. We measure moisture content at intake and again after machining, and any batch outside the acceptable range is either re-conditioned or rejected. Substrates such as MDF and particleboard are checked for density and dimensional consistency, since low-density cores cannot hold hinges securely over time. Steel sheets are verified for gauge and coating weight, because a door that looks substantial on the outside can still fail if the metal skin is too thin at the lock area. Hardware components are tested for cycle life, finish adhesion, and corrosion resistance before they are approved for production. This attention at the front end saves enormous cost and reputation damage at the back end.

Precision cutting, framing, sanding, and finishing determine how a door performs and how it looks. Panels are cut on calibrated equipment to maintain squareness, then assembled in jigs that hold the frame true while adhesives cure under controlled pressure. Sanding is performed in graduated grits to create a surface that accepts stain evenly, because uneven sanding is one of the most common causes of blotchy finishes in wooden doors. Priming and top-coating happen in dust-controlled booths with regulated temperature and airflow so that curing is consistent across the batch. Between each stage, the door passes a visual and dimensional check, and any defect is corrected before the next process begins. The result is a product that feels solid, closes cleanly, and retains its appearance through years of daily use.

Eco-friendly coatings and durable hardware complete the picture. We offer low-VOC and water-based finish systems for buyers whose markets enforce strict environmental or indoor-air-quality regulations, and we can supply documentation to support those claims. Hinges, locks, and closers are selected for their cycle ratings and are aligned during assembly to prevent the sagging that undermines an otherwise excellent door. Multiple inspection stages, including in-process checks, pre-packing review, and random container inspection, ensure that what leaves our facility matches what was approved in the sample. Export packing follows international standards, with corner protection, moisture barriers, edge reinforcement, and clearly labeled cartons that survive transshipment and multiple handling points. When required, we arrange third-party inspection so that buyers receive independent verification before shipment. All of this is how a door supplier earns trust rather than simply winning a quotation comparison.

Our doors are installed across residential, commercial, hospitality, healthcare, education, and real estate development projects. Residential buyers use our interior and entry doors for apartments, villas, townhouses, and renovation programs where consistent quality across many units matters. Commercial clients source office and retail doors that must balance durability with an attractive, brand-appropriate appearance. Hospitality projects require hundreds of matching doors with acoustic performance and low maintenance, and we have supported hotel programs in multiple regions. Healthcare and education clients need fire-rated, easy-clean, and safety-compliant products that satisfy inspectors and facility managers. Real estate developers often combine several categories in one order, sourcing standard apartment doors, premium lobby entries, and fire-rated stairwell doors from a single supplier. This breadth means buyers can consolidate vendors, reduce administrative burden, and achieve better pricing through combined volume.

We export to markets across North America, Europe, the Middle East, Africa, Southeast Asia, and Australia, and we understand that shipping and compliance requirements vary considerably between them. Our team prepares commercial invoices, packing lists, certificates of origin, fumigation certificates where applicable, and test documentation required by local authorities. We work with forwarders experienced in handling bulky, heavy cargo and can quote FOB, CIF, or door-to-door terms depending on your preference. Container loading is planned carefully so that cartons are protected and space is optimized, which directly reduces your landed cost per unit. For buyers new to importing, we provide guidance on sizing conversions, packaging expectations, and realistic lead times so that there are no surprises. If you are evaluating suppliers for the first time, reviewing our HOME page will give you a quick overview of our main product lines and how to reach our sales team.

The ordering process begins with an inquiry and requirement confirmation. You share your door types, dimensions, quantities, finishes, hardware preferences, target market, and any certification requirements, and our sales engineers respond with clarifying questions rather than a generic quote. We ask about installation environment, expected traffic, and climate because these factors influence core material and coating choices. If you have an existing product you want replicated, we can work from photographs, drawings, or a physical sample. At this stage we also discuss target pricing so that we can propose a specification that meets your market positioning rather than an over-engineered solution. Clear information at the start prevents costly revisions later, and it allows us to give you a realistic and reliable timeline.

The next phase covers design, sampling, and quotation. Our technical team produces drawings and, where necessary, a physical sample for your approval, and we refine details until the design matches your expectation. Sampling typically takes one to two weeks depending on complexity and finish requirements, and the sample becomes the approved reference standard for production. Once the specification is locked, we issue a formal quotation with unit prices, payment terms, lead time, and shipping options. MOQ and lead time vary by product type and finish; standard interior doors generally start at low container-load quantities, while fully custom designs require larger minimums to justify tooling and setup. We explain these numbers transparently so you can plan inventory and cash flow with confidence. Any questions about certification, testing, or packaging are resolved before the order is confirmed.

Production, quality inspection, and delivery complete the cycle. After your deposit is received, materials are prepared and the order enters the production schedule, where it is tracked through cutting, assembly, finishing, and packing. In-process inspections occur throughout, and a final pre-shipment inspection verifies dimensions, finish quality, hardware function, and packing integrity. We provide photographs and inspection reports so you can review progress without traveling, and third-party inspection can be arranged at your request. Once the shipment is approved, we book freight, prepare export documents, and coordinate loading, then share all relevant tracking information. After delivery, our team remains available for installation questions, replacement parts, and future orders. This end-to-end process is designed to make overseas sourcing predictable rather than stressful.

We manufacture interior doors such as solid wood, composite, flush, molded, and sliding models, as well as exterior doors including security, steel, aluminum, and weather-resistant entry doors. Our commercial range covers fire-rated doors, hospital doors, hotel doors, office doors, and school doors built to project specifications. We also produce matching jambs, frames, architraves, and hardware sets so that installations are complete and consistent. Customization extends to size, color, finish, glazing, and packaging, including private-label programs for distributors. Because we handle both standard and bespoke products, buyers can consolidate multiple categories into a single order. If a door type you need is not listed, our engineering team can often develop it from a drawing or sample.

Yes, size and finish customization are among our strongest capabilities. We produce metric and imperial dimensions, oversized and arched entries, double-leaf configurations, and slim profiles for tight openings. Finishes include RAL and Pantone color matching, wood grain replication, stained and lacquered surfaces, high-gloss enamel, and textured or distressed effects. We also offer low-VOC and water-based coating systems for markets with strict environmental regulations. Hardware can be specified down to the handle design, including decorative options such as a gold door lever that complements premium interiors. Every custom specification is confirmed with a drawing and, where appropriate, a physical sample before mass production begins.

Quality control starts with raw material inspection, where we verify moisture content, substrate density, steel gauge, coating weight, and hardware performance. Each production stage, including cutting, framing, sanding, priming, and top-coating, has its own documented checkpoint and inspection criteria. We test squareness, dimensions, hinge alignment, lock function, and finish uniformity before a door is approved for packing. Export packing itself is engineered with corner protection, moisture barriers, and reinforced cartons to survive long-distance shipping. Random container inspections and optional third-party audits provide independent verification. This layered system is why customers who place trial orders usually return with larger, long-term contracts.

Minimum order quantities depend on the product type, finish, and level of customization. Standard interior and exterior doors typically begin at container-load quantities, while fully custom designs and new tooling require higher minimums. Lead time generally ranges from three to six weeks after sample approval and deposit, depending on order size, finish complexity, and raw material availability. During peak seasons, we recommend confirming schedules early to secure production slots. We provide a precise timeline in the quotation so you can plan shipment and distribution accordingly. For urgent project deadlines, our team will review capacity and propose the fastest realistic option.
