Trench Grating Systems by Grating Pacific allow the user to combine any of the gratings illustrated below with any of the embed frames in the Embed Frames section of this website. 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.

Grating Pacific Trench Systems and Inlet Sets are manufactured as component products with the grates easily removed for clearing debris from the trenches or inlets. Often security concerns or traffic conditions dictate that the grates must be bolted to the framing. When this option is specified, weld lugs or counter-sunk lands (illustrated in the Fasteners & Banding Section) are installed on the grates and the bolt is installed below the traffic surface of the grating. For high security applications, bolted grates with tamper-resistant fasteners may be further specified.
