Grating Pacific

rench Grating Systems by Grating Pacific allow the specifier to combine any of the gratings illustrated on Trench Grating & Inlet Sets with any of the embed frames profiled on Manufacturing & Installation. Gratings are available in Standard series for pedestrian loads or Heavy Duty series for vehicular traffic. Unlike cast iron or molded trench products, this flexible system allows the user to specify the exact clear opening ("S" dimension) desired. Because Grating Pacific offers five distinct embed frame profiles, the user can select a frame to meet the exact edge condition desired. Bolting the grates to the frames is optional and must be specified. All gratings are provided with plain surface (the optional serrated surface is also available when specified) and open ends are trench banded to maximize drain capacity. Unless otherwise noted, all trench frames and grating are hot dip galvanized after fabrication in accordance with ASTM Specification A-123. Our most popular systems are listed in the table below, however, this listing in no way completely defines this comprehensive product line.


"T" indicates trench grating while "H" indicates type H Heavy Duty grating as shown above. For Standard Duty, specify "TS" etc.	Indicates trench clear span or "S" dimension in inches.	Indicates type of frame from options illustrated on the Frames Specifications page.	Optional component to specify bolted grates. If bolted grates are not required, this component is eliminated.
