Pultruded Grating

Quartzgrip Pultruded Fibreglass grating is specially fabricated for applications that call for high strength and large span. Manufactured with a high glass fibre content of around 55%  this high proportion of glass fibre to resin ratio is the key contributor to grating’s strength.

More details

The pultrusion process utilized in the manufacturing of pultruded fiberglass grating and structural shapes is a continuous and automated process where continuous fiberglass rovings and mat are pulled through guides, a resin bath and pre-formers, then wrapped with a synthetic veil before being pulled through a heated die. The individual components of pultruded fiberglass grating – load bars and each piece of the two piece tie-bar are pultruded separately.

Load bars are then cut to specified lengths as they exit the machine. They are drilled at 6” or 12” centres for tie-bar insertion. Once the bars have been drilled they are spaced proportionately for the width of the panel at 3 ft, 4 ft or 5 ft. The two piece locking tie bar assemblies are then inserted creating multiple bonded intersections of load bars and tie bars, thus providing the security of both a mechanically locked and bonded connection. The final step in the process is to seal the cross bars and holes with corrosion resistant epoxy resin.
