Flattened 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 expanded mesh 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.
The materials usually employed for expanded sheets are:

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

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.
