Steel Grating is welded bearing steel bars and cross twisted bars accoring to required pitch space between steel bars by steel grating welding machines.it is a grid building material.
All gratings are made using high quality standard steel materials which exhibit good hardness and high tensile strength. It is extremely strong, durable and corrosion resistance and great anti-slip performance.
Based on where the grating will be used and its load bearing requirements, steel bars are available in a range of spacing pitch, thicknesses and heights.
- Surface Treatment Finishing of Steel Grating:
Generally Steel Grating is made with hot-dipped galvanized. Also zinc coating can be made according to the client's requirement.
Steel Grating can be called hot-dip galvanized steel grating,stainless steel gratings.Beautiful surface appearance and excellent performance in industry construction projects.
- Materials of Steel Grating:
1) Carbon Steel Smooth Flat Bars,Carbon Steel Serrated Bars,I-Type Steel Bars.
2) Steel Twisted Square Cross Bars,Steel Round Cross Bars.
3)Stainless Steel 304 Grade Flat Bars, Stainless Steel 304 Grade Round Bars.

- Uses and Application of Steel Bar Metal Grating
Offshore Drilling Oil Platform Metal Grating for Petroleum Project
Flooring
Stairs, stair treads
Sewage drain covers, manhole covers and loading ramps
Racks and shelving
Catwalks,Walkway and crossover platforms
Safety steel grids fence
Bridge sidewalks and bridge decking
Architectural uses like building facades or partitions
Security screens in residential and commercial buildings
Steel bar grating has a vast amount of uses ranging from flooring and stairs to bridges and sewage drain covers. It is a smart choice for flooring and stairs in work areas where slipping and falling are a major concern, such as industrial plants, waste-water treatment facilities, or manufacturing operations. The open design makes bar grating the best option for areas that require the passage of light. It also works well for projects that require fast, easy fabrication and installation.
