Paint Finishing Techniques and Color Advantages
Our fiberglass door and window profiles feature an eco-friendly water-based polyurethane finish with full RAL color matching and popular North American standard colors. Engineered to withstand extreme North American climates – from northern freeze-thaw cycles to southern UV exposure and coastal salt spray – the coating delivers strong adhesion, scratch resistance and excellent UV stability. It effectively prevents fading, peeling and cracking under long-term outdoor exposure, maintaining a smooth, uniform surface for decades. For installers and distributors, this means fewer touch-ups on site and fewer finish-related warranty claims.
Flexible Partnership Models
We provide flexible procurement solutions tailored for the North American market. Clients can purchase full-length raw profiles for in-house fabrication, or order pre-assembled finished windows sized to match North American standard opening dimensions. We support mixed container loads, private label options and scheduled restocking programs to match your inventory turnover. Whether for small local installation projects or large regional distribution contracts, we scale supply to your business needs and simplify your cross-border procurement.
Production Processes
We prioritize professional system design as the core of our door and window profiles, rather than simple tonnage pricing. Our systematic profile design is engineered to meet North American performance expectations for water tightness, air tightness, wind pressure resistance and sound insulation, supporting Energy Star and NFRC-aligned performance. All raw materials including resin, glass fiber cloth and paint adopt high-quality branded supplies. Different from peers who omit key processes, we adopt complete pre-treatment procedures before painting, greatly enhancing paint adhesion and long-term finish stability. Supported by mature pultrusion technology and fully automated production lines, every process from raw material processing to finish machining is strictly standardized, delivering high-precision, high-performance products with consistent batch quality.
After-Sales Service
We provide full-cycle after-sales support for all profile and finished window products serving the North American market. Our professional team offers timely technical consultation, installation guidance and troubleshooting support tailored to local installation practices. We support clear quality warranty terms and quick response for product defects or usage issues, with fast spare parts shipping to minimize downtime. Efficient after-sales support minimizes project risks and ensures long-term stable product operation for your customers.

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.
