Paint Finishing Techniques and Color Advantages
Our windows, doors and fire-rated windows for public projects use an eco-friendly water-based polyurethane coating with standard RAL color options. The heavy-duty finish offers strong adhesion, scratch resistance and long-term UV stability, resisting fading, peeling and cracking for decades of service life. This low-maintenance, durable appearance is ideal for government buildings, schools, hospitals and infrastructure.
Flexible Partnership Models
We support public procurement procedures with formal quotations, complete technical documentation and transparent pricing. Supply options include bulk profile supply or finished window and door delivery, all compliant with public tender requirements. Batch sizes and delivery schedules can be structured to match project phases and official procurement timelines.
Production Processes
Our products are built on systematic engineering design, delivering verified performance in water tightness, air tightness, wind resistance and sound insulation. All raw materials – resin, glass fiber and coating – are traceable branded supplies. Full pre-paint surface treatment is standard, ensuring long finish life. Mature automated pultrusion ensures consistent, inspectable quality that meets public project acceptance standards and fire safety regulations.
After-Sales Service
We provide full-lifecycle after-sales service for public projects, including formal warranty documentation, regular maintenance guidance and timely technical support. Our team responds promptly to official service requests and provides full traceability records, supporting asset management and long-term building operation.

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.
