Small Hole Raised Expanded Metal Mesh Copper Expanded Metal Mesh Diamond Hole in rolls

Product Description:

Expanded metal is a type of sheet metal which has been cut and stretched to form a regular pattern (often diamond-shaped) of metal mesh-like material. It is commonly used for fences and grates, and as metallic lath to support plaster or stucco.

Expanded metal is stronger than an equivalent weight of wire mesh such as chicken wire, because the material is flattened, allowing the metal to stay in one piece. The other benefit to expanded metal is that the metal is never completely cut and reconnected, allowing the material to retain its strength.

SWD (Short Way of the Diamond) is the distance from the middle of the bond on one side to the middle of the bond on the opposite side.
LWD (Long Way of the Diamond) is the distance across the largest dimension of the diamond measured halfway between the diamonds.
SWO (Short Way of the Opening) is the width of the opening of the shortest side of the diamond. SWO does not include the strand width, where SWD (Short Way of the Diamond) does.
LWO (Long Way of the Opening) is the length of the opening of the longest side of the diamond. LWO does not include the strand width, where LWD (Long Way of the Diamond) does.

StrandExpanded metal is composed of strands and bonds. Strands form the sides of the expanded metal openings. .
Thickness is the measurement from the top surface to bottom surface of the expanded metal piece.

Applications:

Expanded metal is frequently used to make fences, walkways, and grates, as the material is very durable and strong, unlike lighter and less expensive wire mesh.

The many small openings in the material allow flow through of air, water, and light, while still providing a mechanical barrier to larger objects. Another advantage to using expanded metal as opposed to plain sheet metal is that the exposed edges of the expanded metal provide more traction, which has led to its use in catwalks or drainage covers.

Large quantities of expanded metal are used by the construction industry as metal lath to support materials such as plaster, stucco, or adobe in walls and other structures.

Safety:

Freshly-cut expanded metal has a large number of exposed sharp edges, requiring caution and protective clothing, such as leather gloves and aprons to prevent skin abrasions and cuts.
