Description
This high-performance glass fibre rectangular bar is pultruded in a polyester matrix to meet rigorous specifications. Small cross-section bars are typically manufactured using a unidirectional fibreglass orientation, featuring a smooth surface finish. For larger profiles, the fibreglass layup combines multi-layered cross-ply glass fibre fabrics, resulting in enhanced strength across all axes and excellent mechanical properties.
With a tensile strength surpassing that of steel, these bars are capable of withstanding high loads and stresses, making them ideal for applications where strength and durability are essential. They also offer outstanding electrical and thermal insulation properties.
These glass fibre bars are highly versatile, easily machined and cut to size for customization to meet your project's unique requirements. They exhibit resistance to corrosion and UV radiation, ensuring a reliable and long-lasting solution.
Overall, these bars are the perfect choice for anyone seeking a high-performance, lightweight, and durable material. Their exceptional strength and versatility make them ideal for a wide range of applications.
