Product Description

Thin low carbon steel plate.

Stainless steel plate.

Expanded metal:

Raised Mesh

SWD: Plus 1/4" minus 0" per foot of width

LWD: Plus 3/4 minus 0"

Flattened Mesh

SWD: Plus 1/4" minus 0" per foot of Width

LWD: Plus 3/4" minus 0"

Grating

SWD: Plus 1/4" minus 0" per foot of width

Camber

Measured by placing a straight edge along the concave side of the sheet parallel to the LWD, touching both ends. The maximum distance from the edge expanded metal to the straight edge is the camber

Raised Mesh

1/16" per foot of length

Flattened Mesh

3/32" per foot of length

Out of Square

Expanded metal sheets are not perfectly square as manufactured. Stock size sheets and machine run non standard size sheets will be produced to the following tolerances

SWD: 1/16" per foot of Width

LWD: 1/16" per foot of length

Sheets That have to be perfectly square must go through a secondary process of shearing.

Flattening

Flattened sheet thickness shall be plus or minus 10% of published thickness or strand thickness

Non Standard Sheets

Machine Run

Where tolerances permit, machine run non standard sheet sizes are manufactured to the same tolerances as stock size sheets

Random Shearing

Stock size sheets can be random sheared when a closer tolerance is required. This is a secondary process.

Bond Shearing

Bond shearing can sometimes be performed, with limitations. This is a secondary process.

Finishes:

Cleaning – Carbon expanded metal is lightly oiled and should be cleaned before finishing. The most common cleaning method is an acid or solvent bath with a water rinse. For aluminum, use a non-etching chemical or detergent, then rinse and dry thoroughly.

Anodizing – A surface treatment for aluminum where an oxide coating is added electrochemically to the metal. For interior abrasion resistance a .0025" coating is necessary. Medium abrasion applications for interior or maintained exteriors need a .0004" coating. Use a .0008" coating for exteriors.

Porcelain Enamel – Porcelain enamels can be readily applied to expanded metal. Forming, cutting, welding and drilling should be done before applying the finish. All surfaces should be covered.

Painting, Lacquering, Plastic Coating – Be sure the coating used has good surface tension or wetting properties and viscosity to prevent any pullback from metal edges and webbing-in of diamonds.

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.

Usage:mainly applied as platform and stair treads for constructions,vessels bridges and boilers.They are also used as reinforcement foe instructions and concrete pouring ,radiator grills on all type of vehicles and air-compressors and so on.
