ASTM Q235 304 316 Stainless Steel Grating for Trench & Inlet

ASTM Steel Grating Trench & Inlet Systems

Trench and Inlet Systems combine our most popular gratings and embed frames to provide economic, modular components for construction projects. These products are offered in Standard Duty, designed to serve pedestrian loads, and Heavy Duty, designed to service the most demanding vehicular traffic. Each series is offered with multiple bar spacings (shown below) to address the specific needs of your application.

Bolted Grates

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 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.
