DURAGRATE® Grating and Stair Tread


DURAGRATE® molded fiberglass grating is the chemical resistant flooring choice for many industrial applications. The high resin content (65%) provides long maintenance-free performance.

A higher safety factor is achieved by designing a higher glass content at the bottom of the grating for increased tensile strength. Gratings are one piece construction with the tops of the bearing bars and cross bars in the same plane. The surface is concave top / gritted. Note: All panel sizes available in VE, XVE, PP, GP or FF resin systems. Call TPI for custom panel sizes and resins.

Molded grating is composed of fiberglass rovings combined with a choice of five thermosetting resin systems:
*VE* – a premium grade vinyl ester, for high chemical resistance
*XVE* – a premium grade vinyl ester, with extra fire resistance (a flame spread rating of 10 or less)
*PP* – an all-purpose isophthalic polyester for industrial applications
*GP* – a general purpose orthophthalic polyester for architectural or other applications with less corrosion problems
*FF* – an economical isophthalic polyester for food processing or similar applications

* Corrosion resistant
* Easy to install
* Fire retardant
* Impact resistant
* Cost effective
* Uniform appearance
* Non-conductive
* Maintenance free
* Easy to fabricate
* Bi-directional load bearing
