The global construction and interior design industries are undergoing a massive transformation, shifting away from resource-intensive timber towards sustainable, durable materials. As a leading China PVC WPC Door Factory, we specialize in addressing this transition by supplying next-generation engineered doors that combine the aesthetics of solid wood with the chemical stability of synthetic polymers.
What makes WPC (Wood-Plastic Composite) superior? Wood-Plastic Composite is produced through a homogeneous blending of wood flour, thermoplastic polymers (PVC/PE), and mineral additives. Under high pressure and temperature in automated extrusion systems, these elements form a matrix structure. Unlike natural wood, which is inherently hygroscopic, WPC prevents moisture absorption. In highly humid or fluctuating tropical climates, traditional wooden doors absorb atmospheric moisture, resulting in volumetric expansion, fiber distortion, and eventual structural delamination. WPC doors boast a water absorption rate of virtually zero, ensuring complete dimensional integrity.
Furthermore, WPC structures represent a significant advancement in environmental stewardship. By utilizing recycled wood fiber and post-industrial polymers, we prevent deforestation while maintaining compliance with strict indoor air quality requirements. Our formulas contain no added formaldehyde, eliminating toxic volatile organic compound (VOC) emissions, which is a crucial consideration for LEED-certified and green building developments globally.
Zhejiang Larsom Door Co., Ltd. is a professional manufacturer specializing in the research, development, production, and global sales of high-quality security doors, armored doors, steel-wood doors, and customized entrance door solutions.
Since its establishment, Larsom Door has been committed to providing customers around the world with safe, durable, and stylish door products. Today, the company operates a modern manufacturing facility covering more than 16,000 square meters, supported by an experienced team of over 160 skilled employees. With advanced production management and efficient manufacturing systems, our daily production capacity exceeds 200 sets of premium doors, enabling us to meet both large-scale projects and customized orders with reliable delivery.
To continuously improve product quality and manufacturing efficiency, Larsom Door has invested heavily in advanced automated production equipment, including CNC laser cutting machines, CNC bending machines, automatic welding systems, high-speed turret punching machines, automatic sanding machines, and modern powder coating production lines. These advanced facilities, combined with strict quality control procedures, ensure that every door meets international quality standards.
Quality is the foundation of our business. Larsom Door strictly implements comprehensive quality management throughout every production process, from raw material selection to final inspection. Our products comply with international quality standards and have earned an excellent reputation among customers worldwide.
Today, Larsom Door exports its products to more than 130 countries and regions, including Europe, the Middle East, Africa, South America, Southeast Asia, and Central Asia. Our major customers include building contractors, real estate developers, wholesalers, distributors, and importers. With rich experience in OEM and ODM manufacturing, we provide flexible solutions for customers seeking customized branding and product development.
Guided by the philosophy of "Quality First, Customer Foremost, Innovation for the Future," Zhejiang Larsom Door Co., Ltd. continues to improve its manufacturing capabilities, expand its international market presence, and build long-term partnerships with customers around the world.
Every door manufactured at our facility undergoes a rigorous, fully monitored industrial process to ensure dimensional accuracy, structural strength, and uniform surface finishes.
By using computerized calibration systems during polymer extrusion, we ensure density variations are kept below 1.5%. This uniformity translates directly to consistent impact resistance and prevents warping across the door's surface.
Our surface finishes utilize high-performance UV-curable and CPL (Continuous Pressure Laminate) coatings. This process provides scratch resistance (4H rating) and shields the door from UV discoloration, maintaining color vibrancy for decades.
Because the core is composed of hydrophobic PVC resins and wood flour encapsulated in plastic, moisture cannot penetrate the cellular core. This design makes our WPC doors ideal for high-humidity environments like bathrooms and kitchens.
Managing the procurement of bulk doors requires a balance of quality assurance, manufacturing scalability, and logistical precision. For real estate developers and wholesalers sourcing from a China WPC Door Exporter, these factors are critical to mitigating supply chain risks.
Zhejiang Larsom Door Co., Ltd. addresses these B2B procurement challenges through structured optimization:
Our strategically located facilities near major maritime hubs allow us to optimize container loading and secure lower shipping rates, reducing transit costs for projects in Europe, North America, the Middle East, and beyond.
High-traffic areas require doors with outstanding structural durability. Our WPC and PVC models are designed to resist impact and scratching. With sound transmission class (STC) ratings up to 38dB, they are ideal for hotel rooms, offices, and educational institutions where acoustic comfort is key.
For large-scale housing projects, cost-effectiveness and zero-maintenance durability are essential. Our paint-free, pre-hung door systems install quickly, minimizing on-site labor expenses and preventing tenant complaints about sagging or peeling paint.
In regions like Southeast Asia, coastal Latin America, and the Middle East, standard doors are prone to dry rot and termite damage. Our composite material formulation is naturally resistant to termites and moisture, outlasting conventional timber doors by years.
Under normal indoor conditions, a high-quality WPC door can last upwards of 20 to 25 years without warping, peeling, or cracking. Natural timber doors typically require refinishing, resealing, or repainting every 3 to 5 years, making WPC a more cost-effective, low-maintenance choice over time.
Yes. Larsom's WPC doors are formulated with flame-retardant agents. They typically achieve a Class B1/Class B fire-protection rating under EN 13501-1 and GB 8624. In the event of a fire, they will self-extinguish when the flame source is removed, without producing dense, toxic smoke.
Absolutely. We regularly adapt door leaf widths, frame designs, and hardware pre-drilling to match specific market expectations. For example, we supply specialized 100% waterproof doors with high-durability polymer skins designed to meet the demands of the Israel and Palestine markets.
We do not use urea-formaldehyde adhesives during our manufacturing and laminating processes. Our extruded profiles comply with the strict E0 and E1 European emission standards, ensuring clean indoor air quality and suitability for green-certified buildings.
