GRATINGS & EXPANDED METALS
GRATINGS & EXPANDED METALS - INTRODUCTION
GRATINGS
Carbon steel grating is a heavy duty grating that can be used where open flooring is needed for air, light and heat transmission. It does not exhibit good corrosion resistance, so should not be used in applications that are exposed to corrosive elements. The grating selection is based on load requirement, corrosion resistance, durability, and cost.
SURFACE OPTIONS AVAILABLE:
• Serrated
• Grit
• Painted
APPLICATIONS
Carbon steel grating is used in applications that require strength and is typically used for platforms and walkways in chemical plants, oil rigs, and paper mills. In addition to flooring, bar grating can be used to make drainage ditch covers, catwalks, stairway platforms and stair treads.
EXPANDED METALS
Carbon steel expanded metal is a carbon steel sheet that has been simultaneously slit and stretched into a rigid, non-raveling mesh with diamond-shaped openings. It is available in a galvanized finish to provide corrosion resistance and additional strength.
APPLICATIONS
Expanded metal has a favorable strength-to-weight ratio and is used in many applications that required a strong mesh material. These include air filters, patio furniture and electronic equipment ventilation panels.
GALVANIZED SERRATED GRATINGS
Singapore standard nominal size is 0.9m x 6.1m long (3' x 20').

* Sheet tolerance: SWM + 50mm - 0mm
* LWM + 0mm - 19mm
Notation: LWM = Long Way of Mesh
SWM = Short Way of Mesh
FAQ
Metal grating is a metal product manufactured by puncturing metal sheets or joining metal bars to form a grid structure.
This product is widely used in various industries as stairs, platforms, scaffolding, and protective coverings. The different processes used to produce metal gratings include expansion, perforation, molding, and welding.
Expanded metal is sheet metal that has been cut and stretched into a regular, mesh-like pattern. It is commonly used for fences, grates, and as metallic lath to support stucco or plaster.
