This is a steel grating plate (also known as a steel grid plate), which is a widely used metal building material in both industrial and civilian settings.

Structure and Materials

It is constructed by orthogonally welding flat steel (mainly for bearing weight) and cross bars (mostly twisted square steel, serving as a fixing function) at certain intervals to form a grid-like structure. The main material is mostly carbon steel, and the surface is often treated with hot-dip galvanizing to prevent rust and corrosion, with a lifespan of over 20 years; stainless steel can also be selected for use in high-corrosion environments.

Common uses

Municipal engineering: Drainage ditch covers, rain grates, manhole covers
Industrial scenarios: Factory platforms, walkways, stair treads, equipment ditch covers
Civilian scenarios: Washroom grilles, residential garage drainage ditch covers, boardwalk platforms

Characteristics Explanation High load-bearing capacity and lightweight design Its self-weight is only 1/3 to 1/4 of that of a solid steel plate, yet it can meet the load-bearing requirements for pedestrians, vehicles, and even heavy equipment. Good drainage and ventilation performance The hollow structure can quickly drain water and prevent water accumulation; at the same time, it is conducive to ventilation and heat dissipation, as well as explosion prevention and pressure relief. Anti-slip safety A toothed flat steel design can be adopted, which can provide good friction force even in damp and oily environments. Durable and easy to maintain The galvanized layer is corrosion-resistant, does not accumulate dust easily, and has low maintenance and cleaning costs.
