Services
Pultruded fiberglass components
We manufacture custom pultruded fiberglass components using polyester and polyurethane resins. These thermally insulating profiles provide structural support for windows, doors, and refrigeration units. Our proprietary pultrusion process ensures dimensional accuracy and long-term durability in extreme climates.
Extruded window frames
Our reinforced thermoplastic extrusion process creates window frames with superior thermal performance. These components maintain stability in temperature fluctuations while resisting warping and degradation. Custom color options and finish applications ensure architectural compatibility across building designs.
Door sill manufacturing
We produce durable door sills with integrated moisture resistance features. Our pultruded fiberglass sills combine structural integrity with thermal insulation properties, preventing energy loss at critical building envelope junctions while maintaining aesthetic design flexibility.
Custom composite finishes
Our proprietary finish application creates a permanent bond with fiberglass substrates during pultrusion. This advanced coating system resists UV degradation, physical abrasion, and chemical exposure while maintaining color consistency throughout the product lifecycle without maintenance requirements.
Quality assurance testing
We conduct comprehensive material testing through in-house laboratories and third-party certification bodies. Our quality control processes verify physical properties, thermal performance, and structural integrity against industry standards including UL and FGIA protocols for building component safety and longevity.
