Basalt fiber roving is comprised of strong, heat-resistant basalt filaments, offering durability even in harsh environments and outperforming E-glass. Its cost-effectiveness and comparable performance to carbon fiber make it suitable for large-scale composite material production. Basalt fiber roving is versatile in applications such as fabricating unidirectional cloths for construction, wrapping pipes and cylinders, crafting textiles and geotextiles, building repairs, and as a strengthening material in various composite matrices.
