View Technical DatasheetJakarta, the economic engine of Indonesia, presents one of the most demanding environments for building materials. With an average relative humidity index frequently fluctuating between 75% and 95% and intense heat, traditional timber door frames rot and warp within a few seasons. Moreover, the threat of subterranean termites (Coptotermes formosanus) in the coastal areas of North Jakarta and West Jakarta makes conventional lumber highly vulnerable to structural destruction.
Additionally, modern urban planning inside Jakarta’s major developments—such as the Sudirman Central Business District (SCBD), Pantai Indah Kapuk (PIK), and Kelapa Gading—requires builders to implement durable materials to lower lifecycle maintenance costs. The shift from traditional wood or lightweight aluminum to heavy-duty Wood Plastic Composite (WPC) bathroom doors has become an industry standard.
| Metric | WPC Doors | Solid Wood | Aluminum |
|---|---|---|---|
| Waterproof Index | 100% (Zero Absorption) | Poor (Warps & Swells) | 100% (Prone to Oxide Oxidation) |
| Termite Resistance | Absolute (No Cellulose Target) | Highly Vulnerable | Immune |
| Sound Insulation | High (up to 32 dB) | High (Medium Core) | Poor (Hollow Metallic Resonator) |
| Carbon Impact | Recyclable Polymer + Wood Bio | Deforestation threat | High energy intensity |

View Technical DatasheetZhejiang Larsom Door Co., Ltd. uses polymer-wood matrix engineering to improve environmental performance and ensure structural stability.
Our doors utilize a scientific blend of 60% medical-grade PVC polymers, 30% ultra-fine wood powder, and 10% chemical additives (including coupling agents, UV stabilizers, foaming agents, and flame retardants). This matrix eliminates hollow capillary pathways, ensuring zero moisture absorption even under total submersion.
Rather than joining pieces with weak adhesives, our WPC door panels are formed via high-pressure, twin-screw extruders in a single step. The resulting monolithic structure boasts uniform density, high tensile strength, and is immune to delamination—a critical failure point for typical MDF or plywood doors.
We implement advanced PUR (Polyurethane) hot-melt lamination systems and UV-curing paint lines. This forms a cross-linked protective barrier against household detergents, cleaning acids, cosmetic stains, and intense coastal sunlight common in tropical climates.
Our hollow-core designs feature internal web ribbing configured at mathematically optimized angles. This configuration maximizes structural resistance to compression, impact, and bending, while maintaining a low weight profile that reduces stress on hinges and frames. As a result, the doors deliver long-term durability in high-frequency commercial environments like retail centers and medical clinics.
Zhejiang Larsom Door Co., Ltd. is a leading manufacturer specializing in the research, development, production, and global sales of premium security doors, armored doors, steel-wood doors, and customized entrance door solutions.
Our modern manufacturing facility covers more than 16,000 square meters and is 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, allowing us to supply large-scale projects and custom orders with short lead times.
To maintain high product quality and manufacturing efficiency, Larsom Door has invested heavily in advanced automated production equipment. This includes 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 systems, combined with strict quality control procedures, ensure that every door meets international quality standards.
Customized product configurations designed for different commercial and residential structures.
For upscale residential towers in areas like Menteng or Senopati, we provide customized high-end wood grain WPC doors with integrated acoustic cores. These systems achieve a Sound Transmission Class (STC) rating of up to 32 dB, ensuring privacy and quiet inside bathrooms.
For high-occupancy public housing complexes in Jakarta (Rusunawa), cost efficiency and long-term durability are critical. Our hollow WPC door series offers a practical, low-maintenance alternative that eliminates ongoing repaint cycles and prevents termite damage.
Spas, hotels, and gyms in tropical environments subject doors to high humidity and chemical exposure. Our WPC bathroom doors are designed to handle persistent exposure to steam, chlorinated water, and cleaning detergents without corroding or deteriorating.
Importing construction elements into Indonesia requires navigation of strict customs checks, SNI (Standar Nasional Indonesia) requirements, and import quota checks (API-U / SPI). Zhejiang Larsom Door Co., Ltd. provides comprehensive documentation and logistics support to ensure seamless clearance at Tanjung Priok Port, Jakarta.

View Technical DatasheetHow we adjust our high-precision production lines to match your project specifications.
We supply WPC doors in standard sizes as well as custom dimensions tailored to architectural requirements. This helps minimize on-site alterations during construction.
To reduce labor costs and speed up installation on-site, we use high-speed CNC centers to pre-cut lock pockets, hinge recesses, and ventilation grills according to project drawings.
By shipping pre-machined systems directly from our factory, developers can save on labor costs and minimize alignment issues during final assembly on the construction site.
