Galvanized Expanded Metal Mesh

Expanded metal is infinitely variable in pattern, and can be specified to achieve any critical characteristics.  A larger pattern size will increase open area, light, sound diffusion, and cost effectiveness.  Changing the strand width alters appearances and weight.  In fact, expanded metal actually has a higher strength to weight ratio than in its previous sheet metal state.  Standard expanded metal provides rigidity, while flattened expanded metal has a smoother and safer surface.

The expanded metal mesh ensures excellent ventilation while providing security, safety, and visibility throughout the parking structure.  The aluminum expanded metal provides a durable, long-lasting, and virtually maintenance-free solution to any parking structure exterior.  At a major cost savings compared to wire mesh & perforated, choose expanded metal when designing your new project. 

Galvanizing - Hot dip galvanizing is primarily a protective coating and may have a rough uneven appearance. Where smooth finish is required, other coatings and protective methods should be used. Certain small expanded metal styles do not lend themselves to hot dip galvanizing because the openings become filled with zinc. Warping or distortion may occur during hot dip galvanizing due to the heat of the molten zinc.For these reasons patterns lighter than 18 gauge, with openings of 1/2" or less or any patterns with a weight per square foot of 0.45 lbs or less are not recommended to be galvanized. 

Benefits:

Expanded Metal has a proven track record for quality and value.
The mesh can be easily formed into curved surfaces.
Metal lath improves the appearances of cracking plaster / render.

Features:

Can be provided cut to shape and sizes.
Can be used as a carrier for fire protection to structural steelwork.
The mesh is easily fixed and ready to use.
Wide range of options to suit your specific use.
Strip mesh can be used along the lines of potential weakness.
Corner mesh is used for reinforcing corners formed by plaster / render.
Corner mesh reduces cracking in plaster / render caused by shrinkage.

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.
