The KROSGLASS S.A. Company manufactures polyester sections reinforced with glass roving by using continuous (pulltrusion) method. This method is usable for manufacture of sections with various shapes - round bars, flat bars, angle bars, tee bars, and wedges. Sections are manufactured by continuous impregnation of soft roving skeins with resin, then forming the shape, curing the resin and cutting the sections into lengths. The content of glass in the form of parallel roving skeins is high, typically reaching 65.5 - 75% (mass) depending upon the type of raw materials and process parameters. Therefore such sections feature with very high strength in longitudinal direction.
