Engineering Overview & Technical Application

When industrial walkways and platforms require wide support spans with minimal deflection, pultruded GRP gratings are the premier engineering solution. Manufactured with 65-70% continuous glass roving content pulled through heated steel dies, our pultruded I-bar and T-bar gratings provide higher stiffness and unidirectional load capacity than molded panels.

Common Queries

Frequently Asked Questions

Detailed technical and commercial answers from our composite product engineering team.

Choose pultruded gratings when you have wide support spans (over 900mm) or require heavy unidirectional vehicle/pedestrian loading with tight deflection limits.

Yes. Our isophthalic and vinyl ester pultruded profiles are specifically engineered for cooling towers, resisting continuous warm moisture, biocides, and chlorine without softening.

Cross rods are mechanically locked through precision-drilled web openings and chemically welded with high-strength vinyl ester resin adhesives.
