Light Duty Steel Grating

Where the light-duty boundary starts

A light-duty specification begins with the actual duty: pedestrian traffic, occasional maintenance access or another defined light-load condition. The clear support span, load type, allowable deflection and opening-size rule are checked together before a smaller section or wider pitch is proposed.

If concentrated loads, trolley wheels, forklifts or vehicles enter the brief, the decision moves out of the light-duty range and into a dedicated load review. See Heavy Duty Steel Grating for that selection route rather than carrying an assumed light-duty section into a more demanding area.

Matching material to a light-load budget

Material economy comes from matching the entire panel to its verified duty. For carbon-steel work, the practical comparison is between bearing-bar section, pitch, support span and the selected finish—not a generic “light” label. Wider spacing or a smaller section may reduce steel and handling weight, but only where the opening rule and deflection target permit it.

Material grade, surface type and finish are confirmed per project after the environment is known. Outdoor carbon-steel panels can be hot-dip galvanized after fabrication per ASTM A123 / ISO 1461 or the customer standard, with coating results reported rather than promised as a fixed thickness.

• Provide clear span and bearing-bar direction before comparing sections
• State uniform, point and any wheel loads separately
• Confirm the maximum permitted opening for people, tools or small objects
• Use the heavy-duty route when concentrated or wheel loads are present
