Heavy Duty Stainless Steel Floor Trap Grating
Hot-dip galvanized steel grating is available in three main styles: Plain Style Steel Grating, Serrated Style Steel Grating, and I-Bar Type Steel Grating.

We offer both standard steel grating designs and custom manufacturing to meet specific client requirements.
Steel Grating Classifications by Application
30mm Spacing Steel Grating (Common Type)
Featuring a 30mm center distance for flat steel that meets US standards, this type offers superior surface impact resistance. Ideal for drain covers, stair treads, and applications in power plants, sewage treatment facilities, chemical plants, airports, and docks.
40mm Spacing Steel Grating (Economical & Lightweight)
Designed to meet British standards for walkways and stairs, this is the optimal choice for applications with smaller spans. Commonly used for warehouse shelves, trestles, and protective fences.
60mm Spacing Steel Grating (Mining Industry)
Specifically developed for mining applications, this design allows mineral splashes to pass through the grating surface, maintaining cleanliness and safety. Frequently used in walkways along conveyor lines and processing plants.
Additional Classification Methods
