LSD165 Fiberglass Sliding Door

Our pultruded fiberglass profiles for door and window fabrication feature an eco-friendly water-based polyurethane coating system with full RAL color matching. The paint film is applied over a complete pre-treatment base, delivering strong adhesion, scratch resistance and long-term UV stability. For manufacturers, this means no secondary painting is required after cutting and assembly; profiles go directly from stock to production line, and finished doors and windows resist fading, peeling and cracking for years of outdoor service.

We support flexible procurement aligned with your production schedule. Order full-length profiles in standard or custom sections for in-house fabrication, or take delivery of pre-cut kits ready for assembly. Whether you need regular bulk stock or project-specific runs, we adjust batch sizes and lead times to match your workflow and reduce your inventory holding costs.

We build profiles around engineered system performance, not per-ton pricing. Every cross-section is designed for precise water tightness, air tightness, wind load resistance and acoustic insulation. Branded resins, glass fiber reinforcements and coatings are used throughout, and full pre-treatment prior to painting is never skipped. With mature pultrusion lines and fully automated production control, each batch delivers consistent dimensions, uniform wall thickness and reliable mechanical properties, so your output stays consistent from order to order.

Our technical support team works directly with your production and engineering staff. We provide profile selection guidance, processing parameter recommendations and troubleshooting for fabrication issues. All products come with a formal quality warranty, and we respond quickly to material or performance concerns to keep your production line running without interruption.
