Why 1100 kg/m³ Density Matters
Material density is one of the main factors affecting the stability and processing performance of a WPC door panel. Our high-density WPC raw material can reach approximately 1100 kg/m³ according to the confirmed formulation and specification.
Compared with low-density alternatives, a high-density formulation provides a stronger and more solid material structure. It supports improved resistance to deformation and reliable performance during cutting, drilling, profiling, assembly, transport and installation. When correct hardware reinforcement and installation methods are used, the dense structure also supports dependable fixing for hinges, locks and other door hardware.

Waterproof and Moisture Resistant
WPC does not react to moisture in the same way as conventional wood-based materials. It is designed to resist water absorption, swelling, rotting and moisture-related deformation. This makes it suitable for bathrooms, hotels, apartments, schools, hospitals, dormitories, villas and commercial interiors, especially in humid, tropical and coastal markets.
Termite and Insect Resistant
The wood-plastic composite structure is much less attractive to termites and wood-boring insects than traditional timber. This property helps reduce maintenance requirements and supports a longer service life for finished doors in regions where insect damage is a frequent concern.
Compression Resistance and Hollow Core Stability
Our hollow WPC panels use carefully arranged internal chambers to balance weight, material efficiency and structural stability. Combined with the high-density formulation, the reinforced structure offers reliable compression resistance and helps the panels remain stable during stacking, transport, processing and normal service.
Factory Capacity and Quality Control
Bulk WPC panel inventory prepared for processing, packing and project supply.
Shenghao is supported by experienced production teams and WPC manufacturing resources in Foshan and Dongguan. Automated extrusion processes help control material mixing, forming, cooling and cutting, while organized production planning supports regular wholesale orders, project quantities and container shipments.
Quality control focuses on the factors that matter to door manufacturers: formulation consistency, panel density, dimensions, surface condition, straightness and cavity structure. Product specifications are confirmed before mass production, and finished materials are inspected before packing.

Customization Options
Different factories and target markets require different raw-material configurations. Customers may provide samples, technical drawings, target dimensions or performance requirements. We can discuss the following items before quotation and production:
· Panel width, thickness and cutting length
· Hollow-core structure and cavity design
· Door frame and architrave profiles
· Material density and formulation
· Base color and surface texture
· Finishing method and downstream processing
· Packing method and container-loading plan
Applications
WPC raw materials can be developed into finished door systems for a wide range of residential and commercial projects, including hotel rooms, apartments, bathrooms, bedrooms, schools, hospitals, dormitories, villas, offices and other interior spaces. The combination of moisture resistance, insect resistance and structural stability makes WPC especially practical for demanding climates and projects requiring reduced maintenance.
WPC interior door systems are suitable for hotels, apartments and other high-use projects.
