Paint Finishing Techniques and Color Advantages

Our complete range of window, door, fire-rated window and skylight profiles all share the same premium water-based polyurethane finish with full RAL color options. The coating is highly scratch-resistant and UV-stable, maintaining a smooth, uniform appearance in outdoor conditions. For distributors, this means one consistent quality standard across your entire product portfolio, strong retail appeal and minimal after-sale complaints about finish degradation.

Flexible Partnership Models

We offer distributor-friendly terms including mixed SKU orders, container-load pricing and consignment stock options. You can stock full-length profiles in popular sizes and colors, or place project-specific orders on behalf of your downstream clients. No MOQ penalties for mixed batches, and factory-direct pricing protects your margin while keeping you competitive.

Production Processes

All our profiles are manufactured on automated pultrusion lines using branded raw materials and a strict quality system. Unlike lower-cost suppliers that skip surface pre-treatment, we apply a full preparation process before coating to ensure long-term adhesion. Systematic structural design guarantees reliable water tightness, air tightness, wind resistance and sound insulation across every profile type. Large-scale production capacity ensures steady supply even during peak seasons.

After-Sales Service

We back our wholesale partners with a complete warranty program, marketing materials and technical training for your sales team. If your end customers encounter installation or performance issues, we provide joint troubleshooting and fast replacement support to help you preserve customer relationships and reduce your own service workload.

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.
