Import Fiberglass Windows & Door Frames — Buy in wholesale FOB from Supplier in China

Fiberglass windows and door frames from Waytong Composites are manufactured using a composite of polyester resin reinforced with continuous glass fibers, resulting in a material with tensile strength comparable to steel but at one-quarter the weight. The frames are extruded to standard dimensions of 100mm to 150mm in width, with wall thicknesses ranging from 3.5mm to 5mm, ensuring structural rigidity without excessive mass. These frames are designed to meet the thermal performance demands of modern construction, with low thermal conductivity values typical of fiberglass-reinforced polymer systems.

The polymer matrix is formulated to resist UV degradation and moisture ingress, making the frames suitable for coastal and high-humidity environments. Unlike vinyl or aluminum, fiberglass maintains dimensional stability across temperature extremes, reducing the risk of warping or seal failure over time. Surface finishes include powder-coated or wood-grain laminated options, applied to meet aesthetic preferences without compromising the underlying composite integrity. The material is non-combustible and emits no volatile organic compounds during normal use, aligning with green building standards.

These frames are primarily sourced by architectural contractors in Europe, North America, and Australia for high-end residential and light commercial projects requiring long-term durability and energy efficiency. Buyers typically order in full-container quantities, with standard packaging in wooden crates protected by plastic film. Lead times vary based on order volume and customization, and trade terms are commonly FOB Nanjing or CIF port of destination. Certification for impact resistance and air permeability is available upon request but not pre-verified.

Waytong Composites is a manufacturer based in Nanjing, Jiangsu Province, China, with a registered address at No.8, Pukou Avenue.
