dpwh steel box This document establishes standard specifications for drainage steel grating with frames used by the Department of Public Works and Highways in the Philippines. It defines different classes of grates based on loading conditions and intended . For floors I'd use 16 or 18 gauge hot rolled pickled and oiled (HRPO) sheet. Pickling just removes the scale from hot rolled sheet and has no effect on hardness or workability. The oil is on it to prevent rusting prior to use. For the same thickness, hot rolled sheet is much easier to form than cold rolled because its softer.
