Explore our certified range of interior swing, sliding, and waterproof composite doors, custom-milled to meet rigorous project blueprints and architectural specifications.
Within the architectural hardware and building materials market, selecting commercial-grade doors demands solutions that withstand thermal, physical, and chemical challenges. Zhejiang Larsom Door Co., Ltd. stands as a premier manufacturer, offering next-generation PVC Veneered WPC (Wood-Plastic Composite) Doors that excel in strength, moisture resistance, and dimensional stability.
Traditional hollow core doors and MDF components suffer from structural delamination under dynamic vapor pressure. Our WPC cores utilize a co-extruded homogeneous blend of polymer microcrystalline plastics and kiln-dried lignocellulosic wood fibers, cross-linked using targeted coupling agents. The resulting dense, solid core eliminates moisture absorption channels.
By laminating this robust substrate with engineered PVC film, we achieve superior surface protection against impact, scratch, moisture, and chemical cleaning agents. This process provides a maintenance-free, eco-friendly interior door option ideal for high-traffic environments, multi-family housing, and premium hospitality projects.
Our co-extrusion technology yields a density of 0.8g/cm³ to 1.1g/cm³. This range provides exceptional screw-holding strength, reliable flexural modulus, and improved acoustic damping coefficients (STC 32dB+), outperforming conventional particleboard and hollow timber cores.
Architects specify Larsom Doors globally due to our climate-specific product configurations that address localized thermal and physical challenges.
Developed with UV-stable stabilizers and high-density formulations, our doors withstand temperatures up to 55°C without warping or bowing. Designed for sand-proof and air-infiltration sealing, these doors deliver reliable performance in dry, arid desert environments, making them ideal for high-end residential and commercial projects in countries like the UAE, Saudi Arabia, and Qatar.
Engineered to comply with rigorous indoor air quality codes (EN 717-1 / ASTM E1333), achieving E0 formaldehyde emission ratings. Fully compatible with CE-marked security hardware and multi-point lock systems. Our acoustic options conform to building regulations for apartment entrances and multi-occupancy structures.
With 100% moisture barrier properties, these doors prevent termite damage, rot, and mold growth. Highly stable in regions with high humidity and monsoon activity, including Singapore, Malaysia, Indonesia, and Vietnam. Perfect for bathrooms and utility rooms where moisture levels remain high.
Our quality assurance is rooted in our automated production. We manage every step of the process within our 16,000 square meter facility.
High-capacity machinery processes raw components with structural precision down to 0.1mm tolerance.
Advanced CNC programming profiles lock pockets and hinge locations to match international hardware standards.
Automated bending machines form structural frame components to ensure rigid construction.
High-speed punch systems pierce hardware installation templates cleanly, maintaining structural integrity.
Hydraulic hot presses bond the composite panels and core frame, preventing separation over time.
Combines internal sound-dampening structures with solid-wood rail reinforces, providing optimal structural balance.
Automatic sanding equipment preps the surfaces, ensuring strong adhesion for the PVC veneer.
High-speed routers carve detailed 2D and 3D architectural profiles directly into the composite substrate.
Automated UV-curing lines apply protective coatings that enhance scratch resistance and retain surface color.

Get detailed technical answers regarding the application, structural properties, and deployment of our WPC doors.
Our doors use a hollow-core WPC extrusion that balances weight and structural rigidity. The door skin consists of a wood-plastic composite layer under high-pressure lamination, finished with a decorative PVC film via a vacuum hot-melt process to prevent edge delamination.
Our polymer formulation limits linear thermal expansion (typically under 3.5 x 10^-5/°C). This stability ensures the doors do not warp, stick, or bind under high temperature swings, even when used on exterior-facing partition walls in arid climates.
Yes. WPC boards machine like dense timber. Standard CNC routers, routers, circular saws, and drill bits cut the material cleanly. For heavy commercial closers and locksets, we recommend pre-drilling pilot holes to maximize screw withdrawal resistance.
Larsom products meet RoHS and REACH standards. They contain no added lead, phthalates, or heavy metal stabilizers. The production uses recycled polymer bases and wood processing by-products, earning points under green building programs like LEED and BREEAM.
Standard production cycles range from 20 to 30 days from deposit receipt and CAD approval. With a daily capacity of 200+ sets, we can adjust scheduling for larger multi-residential projects.
Yes. We offer fully integrated pre-hung systems. We extruded matching WPC frames, adjustable architraves, and matching PVC finishes to speed up on-site installation.
