Steel Grating

Steel grating is used for platforms, walkways, stair treads, trench covers,
drainage covers, bridge side paths, and industrial flooring. It is made from
bearing flat bars and cross bars by pressure welding or press locking. Common
materials include Q235 low carbon steel, galvanized steel, and stainless steel.
Alloy steel can be checked by order. Surface can be plain, serrated, or I-bar
type. The most widely used finish is hot dipped galvanized for outdoor and
humid environments.
