Expanding Metal is used widely throughout the transportation industry, Agriculture, Security,

Machine guards, Floorings, Construction, Architecture and interior design.

The use of this kind of expanding metal mesh is highly beneficial, and of cost saving and low

maintenance,Ventilation properties,Excellent weight-to-strength ratio,Economical

We manufacture a full range of standard and flattened expanded metal, structural grating

micro mesh and decorative patterns. Raw material can be produced in carbon, galvanized,

stainless steel or high strength alloy steel. Certain alloys of copper, brass, bronze and

plastics can be expanded as well.

According with the mesh we can divide:

Expanded diamond;
Expanded Square;
Expanded round;
Expanded Hexagonal.

The materials usually employed for expanded sheets are:

Stainelss steel;
Carbon steel;
Aluminium available in rolls or sheets.

If you can envision it,We can supply it.   TEL:0086-311-87878922 E-mail:sales@steellong.cn MSN：Service@Steellong.Cn

Strand and Bond
Expanded metal is composed of strands and bonds. Strands form the sides of the expanded metal openings. Bonds are where the strands intersect. In other words, the bond is where each diamond shaped opening is connected with the next opening. 

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
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.
Open Area
Expanded metal contains open spaces (the diamond-shaped openings) and material. Open area is the total area of the diamond openings divided by the total area of the sheet or roll of expanded metal and is expressed as a percent. In other words, open area describes how much of the expanded metal is open space. If expanded metal has a 60 percent open area, then 60 percent of the expanded metal is open space and 40 percent is material. 
Gauge or Thickness
Thickness is the measurement from the top surface to bottom surface of the expanded metal piece. Gauge is the most common measurement, but thickness can also be measured in fractional inches or millimeters. This gauges and weights chart can provide additional information. 
Width and Length
Length is the measure of the longest side of the expanded metal sheet or cut-to-size piece. Width is the measure of the shortest side of the sheet or cut-to-size piece.
