Why Use GRP Pultruded Profiles?

These profiles have generated exciting results in bridges, buildings and other structures. The construction industry is under constant pressure to produce durable structures that are lighter, stronger and quicker to build.

GripClad GRP pultruded profiles are made from glass reinforced isophthalic polyester resin. This is reinforced with glass fibre and includes continuous strand mat and a polyester surface veil as the surface layer. This combination gives excellent corrosion resistance and long-life durability.

We supply a range of GRP Pultruded Profiles including Tube, I-Beam, WFB H-Beams, Channel, Box Section and GRP Angle Section to standard EN13706 E17 or E23, offering a wealth of construction opportunities.

Typical uses in fabrication of stairs, access platforms, ramps and step access cable/pipe walkovers.
