Expanded Metal Grating (Made of Carbon Steel Mostly) is made of metal sheet expanded in the regular form and then going through a cold rolled reducing mill. In this process the length of the sheet is elongated - usually about 5% - but the width of the sheet remains the same. The sheet is then sent through a leveler to maintain its flatness.
General Information about Expanded Metal Steel Gratings:
Holes: Diamond, Square
Pattern: Standard - raised surface
Feature: Elegant, Press strength, durable, Rustproof, rigid
Common Specification:
Grating Panel (Long way) Size: 4.5 --- 100mm
Short Way Size: 2.5 --- 50mm
Strand thickness: up to 8.0mm
Strand width: MAX to 8.0mm
Benefits of Using Expanded Steel Gratings:
•Expanded metal permits free flow of light, heat, sound and air
•Cost effective alternative to perforated metal. You don't pay for the holes; there is no waste during the expanding process
•Expanded metal grate won't unravel when cut, unlike woven wire
•Available in a variety of mesh configurations including diamond, square, round, hexagonal plus architectural and decorative patterns
•Expanded metal is a formidable barrier when used in security applications
•Easily fabricated, finished, installed and formed
Application: Expanded steel grate panels are mainly applied as platforms and walking stair treads for constructions, vessels, bridges and boilers and also be used as reinforcement for light construction materials and concrete pouring, radiator grills on all types of vehicles and air compressors, safety guards for gear-drive equipment on various kinds of machines.

Expanded metal grating is the most practical and economical way to assure strength, safety, and a non-skid surface. Expanded metal grating is ideal for use on plant runways, working platforms, and catwalks, as it is easily cut into irregular shapes and can be installed quickly by welding or bolting.
