ASTM Q235 304 316 Stainless Steel Grating for Trench Grating Systems
Trench Grating Systems
Trench Grating Systems allow the user to combine any of the gratings presented in our Trench & Inlet Systems page with any of the frames in the Embed Frames section of this website. Systems are available in Standard Duty for pedestrian loads or Heavy Duty 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 we offer 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.
How To Specify Trench Systems
Trench systems are specified by component model numbers. Simply follow the sample specification below.
