Expanded Metal and Bar Grating
Expanded Metal
Expanded metal is lighter per foot and stronger per pound than the sheet of metal from which it is made. The metal strands forming the open diamonds permit light, heat, sound, and air to pass through; yet present an impenetrable barrier to intruders. It is available in steel, aluminum and stainless steel.
Standard (not flattened) expanded metal has a variety of uses, including baskets, bins, fencing, displays, gratings, grilles, guards, racks, reinforcing, screens, shelving, trays, enclosures, and partitions.
Flattened expanded metal is made by the same process as standard expanded metal but is then passed through a series of rolls that flatten the strands and bridges. This reduces the thickness of the original sheet approximately two gauges while retaining all the original metal. Flattened expanded metal provides an almost unlimited number of uses due to it being decorative, strong, and easy to work with.
The hole design of a typical piece of expanded metal is:
LWD = long way of design
LWO = long way of opening
SWD = short way of design
SWO = short way of opening
Check out the available sizes below and remember that other sizes are available on special order:
Size of Opening = width and length of opening (see above diagram)
Design Size = length from the center of a bond to the center on the adjacent bond (see above diagram)
Strand Thickness = actual gauge of strand once produced
Overall Thickness = overall thickness of material

Expanded Metal Grating
Expanded metal grating is the most practical and economical material you can use when a safe, strong, and non-slip surface is required. It is not woven, not welded, by sturdy, solid steel that is pierced and stretched from a single plate.
The open diamonds prevent the accumulation of slippery grease, mud, and snow, while still allowing light and air to pass through. It can be cut to fit irregular shapes and can be welded to supporting members. It has a neat appearance, long life, and is free from needing repairs and maintenance. It is low in cost and easy to construct, making it perfect for plant runways, catwalks, and working platforms.
We can furnish promptly the following other items of Expanded Metal Grating: Walkway 4.27 Ibs. per sq. ft. and Skywalk 3.14 lbs. per sq. ft.
