GRP Square and Rectangular tubes
GRP square profiles are pultruded in a polyester matrix. The fibreglass layup is a combination of multi-layered cross-ply glass fibre fabrics, giving an enhanced strength across the axis for all round excellent mechanical properties, pultruded to BS EN 13706 standard. Profile thickness less than 6mm are manufactured to E17 specifications (full section modulus, GPa17). Structural profile thickness 6mm and greater are manufactured to E23 specifications (full section modulus, GPa 23).
