Welded Bar Grating Trench Cover System | Hot Dipped Galvanized | Fish Tail Frame - HeslyGrating
Welded Bar Grating Trench Cover System

HeslyGrating allows the specifier to combine any of our Standard Duty pedestrian grates or Heavy Duty vehicular gratings with any of our popular Embed Frames. Unlike cast iron or molded trench products, this flexible system allows the user to specify the exact clear opening (“S” dimension) desired.
All gratings are provided with plain surface (the optional serrated surface is available when specified) and open ends are trench banded to maximize drain capacity.
Unless otherwise specified, all trench frames and grating are hot dip galvanized after fabrication in accordance with ASTM Specification A123.

Load Capacity of Heavy Duty Steel Grating
| Important ! The charge-capacity at the grating is determined by the height and thickness of the bearing-bars (=supporting-bars). The bearing-bar must always be supported. Therefore, the bearing-bar is in all our documents = first dimension. Cross-bars and bordering off the grid contribute to the stability. |
