Stainless Steel Expanded Metal

Stainless Steel Expanded Metal is made of high quality Stainless Steel sheet/coil after

being expanded on the automatic expanded machines. Stainless Steel expanded metal is used

in a variety of corrosive atmospheres; its long life pays back its seemingly high cost.

Stainless Steel Expanded Metal is an extremely versatile material, available in a variety of ferrous and non-ferrous metals and a wide range of mesh sizes.

Although there are standard designs, expanded metal is almost infinitely variable

in pattern and can be specified to achieve whatever characteristics are most critical

for your applications. Increased pattern size alters open area and improves cost effectiveness.

Varied strand width changes appearance and weight. Our design/engineering team works closely

with our customers to offer practical recommendations and design solutions.

The use of Stainless Steel Expanded Metal is various:

Shelters, protective barriers for machinery, against rats,concrete reinforcement , cold store

reinforcement, railings , gangways, fencings.

According with the mesh we can divide:

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

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. 
Determining SWD, LWD Direction
The illustration to the right shows the correct way to designate SWD and LWD dimensions in relation to the length or width.

Shearing Types
Bond Shearing- The material is cut on or near the center of the bond eliminating prongs or jagged edges. Bond shearing is only possible if the dimensions fall directly between bonds. If a bond shear is not possible and you want a smooth edge, U-edging can be installed.

Random Shearing - The material is cut wherever the dimensions fall. This type of cut may leave jagged edges, prongs, and incomplete design patterns.
