We combine physical resistance design with advanced wood-panel polymers to serve high-end construction requirements across the globe.
Since our inception, we have driven innovation in door safety, durability, and contemporary styling. Operating a specialized 16,000 square meter manufacturing park, we house over 160 highly skilled technical professionals. With optimized ERP logistics and advanced structural steel fabrication, our daily production capacity exceeds 200 sets of premium engineered doors. This high-capacity output enables us to support fast-track commercial developments, large residential projects, and fully customized architectural designs with guaranteed lead times.
To assure absolute structural precision, Larsom Door invests heavily in state-of-the-art automated tooling. Our plant features CNC laser cutters, high-precision CNC bending brakes, robotic gas-shielded welding installations, high-speed turret punch presses, automated panel sanding runs, and high-efficiency thermoset powder coating lines. By ensuring every millimetre of structural frame, core insulation, and exterior melamine lining conforms to rigorous international building standards, we guarantee unmatched security and longevity.
Fully compliant with global construction codes. Offering certified OEM and ODM manufacturing capabilities.
How engineered melamine security doors resolve safety, durability, and cost challenges for modern developers.
Ideal for apartment corridors, hotels, and multi-family residential zones. Melamine-faced doors offer scratch resistance, ease of cleaning, and high impact resistance, shielding the structural core from consistent physical wear.
Reinforced with internal galvanized steel plates, solid mineral cores, and multi-point perimeter locking bolts. The outer melamine veneer conceals a heavy-duty armoring array, combining domestic elegance with absolute safety.
Utilizing high-density internal honeycomb structure, perlite core, or polyurethane composite insulation. Yields high STC (Sound Transmission Class) values and excellent thermal resistance, lowering energy expenditure.
Different territories demand unique specifications. Larsom Door addresses precise regional requirements.
Thermal & UV Stability: Under high solar radiation and extreme heat index, traditional wood doors warp and split. Larsom’s melamine finishes are treated to resist high UV index, while inner structural steel panels sustain structural shape in high humidity coastal areas.
Eco-Safety & Fire Safety: Conforming to low-formaldehyde emission (E1/E0 grades) and EN 1627 RC2/RC3 security profiles. Our doors integrate fireproofing seals and non-toxic core fillers to meet the stringent ecological and fire-safety compliance protocols of Western Europe.
High durability & Lock Integration: Supports major smart lock and access control hardware (RFID, biometric, keypad). Meets architectural demands for modern visual finishes with certified soundproofing parameters (STC ratings) for premium multi-family housing complexes.
A visual step-by-step display of Larsom Door's high-tech manufacturing processes, ensuring structural integrity.
Our production process is tailored to structural stability. From Plate Shearing and CNC Cutting of thick steel, to the hot press application (Pressing Plate) of melamine resins over dense engineered wood composite substrates, each step is optimized. Sanding machines verify uniform calibration, preventing surface delamination, while computer-guided engraving creates precise channels for decorative metal inlays and edge profiles.
With direct exports to over 130 countries, Zhejiang Larsom Door Co., Ltd. streamlines customs clearances and handles structural certifications. We coordinate directly with port agents in the Middle East, Central Asia, Europe, and South America to ensure hassle-free transit.
We offer builders, real-estate firms, and distributors localized engineering support, customized CAD design mockups, and hardware matching assistance. Whether you need customized dimensions, frame variations, or specific thermal barrier properties, our engineering team tailors options to fit your local building codes.
Larsom Door is consistently pioneering next-generation security door mechanics. Our ongoing R&D focuses on three pillars:
Professional answers regarding Melamine Finish Security Doors, technical specifications, and project bulk ordering.
Melamine finishes are made of thermosetting plastic resins fused to a substrate (like MDF/HDF) under heat and pressure. This creates a surface that is highly resistant to scratches, impact, moisture, and chemical cleaners. Unlike natural wood veneers, it does not warp, rot, or fade under sunlight, maintaining its appearance in high-traffic commercial environments while housing a heavy-duty steel core.
Every melamine-finished security door begins with an internal core frame made of high-tensile steel plate, supported by vertical and horizontal steel U-ribs. Soundproofing and thermal insulation materials (like rockwool, mineral board, or polyurethane) are packed inside this core. The outer panel is dressed with a premium melamine skin, offering an elegant visual profile that conceals the rugged, anti-intrusion steel structure.
We manufacture fire-rated wooden, steel-wood, and composite doors to conform to international fire codes (such as AS1905.1 standards and EN profiles). Depending on project specifications, we can customize the doors to offer up to 30, 60, or 90 minutes of fire resistance, utilizing specialized intumescent seals and fire-retardant melamine surfaces.
Yes. We specialize in OEM/ODM production. We can pre-drill, hollow out, and route cable conduits inside the core structure to accommodate smart locks, digital door viewers, biometric handles, and keyless access control units. Simply provide your lock specifications, and our CNC machinery will cut matching mounting cavities.
Our daily production capacity exceeds 200 premium door sets. For custom project profiles, lead times average between 25 and 35 days from technical drawing confirmation. While we focus primarily on container-load volumes for builders and distributors, we support smaller initial orders for mock-up validation. Reach out to our technical team for custom project quotes.
