Paint Finishing Techniques and Color Advantages

Our industrial-grade door and window profiles feature a heavy-duty water-based polyurethane coating with full RAL color options, formulated for harsh warehouse and factory environments. The finish provides strong adhesion, chemical resistance and excellent UV stability, effectively resisting fading, peeling and cracking from long-term exposure to dust, moisture and mild industrial chemicals. It maintains a smooth, easy-to-clean surface for decades, reducing ongoing maintenance for industrial facilities.

Flexible Partnership Models

We tailor supply solutions for industrial and warehouse construction projects, including bulk profile supply for large-span factory buildings and finished high-level windows and industrial doors. We schedule deliveries to match your construction phasing, from steel structure erection through to enclosure completion. Custom reinforced profiles and oversized dimensions are available to meet industrial load and opening requirements, simplifying your procurement for industrial facilities.

Production Processes

Our industrial profiles are system-engineered for demanding environments, prioritizing air tightness, water tightness, wind resistance and structural rigidity over simple tonnage pricing. Premium industrial-grade resins, high-strength glass fiber and corrosion-resistant coatings are used throughout, with full pre-paint surface treatment to ensure long-term finish adhesion even in dusty, humid conditions. Mature pultrusion technology and automated production lines deliver consistent, high-strength products batch after batch, meeting the durability requirements of industrial construction.

After-Sales Service

We provide dedicated industrial project support including installation guidance for large openings, regular maintenance recommendations and priority response for operational issues. All products carry a comprehensive industrial warranty, and our team responds quickly to performance concerns to help minimize downtime for factory and warehouse operations.

GRFPU Pultrusion Process

GRFPU material as one thermoset composites are built up by polyurethane resin as a matrix (about 20%) in combination with continuous fiber-reinforced (about 80%) materials, which is produced through a proprietary injection pultrusion molding process into a specific cross-sectional profile.
