Expanded Metal Mesh

Expanded metal mesh products are produced from solid sheets of carbon steel, galvanized steel, or aluminium and other metals/alloys.  In the expanding process, the sheet is simultaneously slit and stretched, expanding the slits into diamond-shaped holes of uniform size, shape and regularity.

No metal is lost in the expanding process and the final product is stronger per kilogram and lighter per metre than the original sheet.  The newly formed strands and knuckles of the diamond-shaped trusses are at an angle to the original plane of the sheet, adding strength and rigidity.  Because it is made from a solid sheet of metal, expanded mesh can never unravel.  The metal strands which form the open diamonds of the new sheet permit light, heat, air, liquid, and sound to pass through, yet produce a virtually impenetrable barrier to larger solid objects.  Even if cut at one or more points, the remaining strand intersections continue to hold.

TrussForte’s expanded metal mesh range includes popular brands such as Ornamesh®, Louvamesh®, Balustmesh®, Ruralmesh®, Maximesh®, Gridmesh® and Rendalok®, all formerly offered by BlueScope Lysaght.  TrussForte also now offer Rendalok® Fire Proofing which is a heavier version of our popular Rendalok®, and is suitable for reinforcement of spray applied fire proofing plaster.

Often incorporated as a popular architectural feature, expanded metal mesh offers the benefits of decoration, protection, support and security.  This versatile mesh allows light, heat and air through, while retaining its strength forming a very strong barrier for security purposes. TrussForte manufacture expanded metal mesh for every application including various:

  • pattern types,
  • mesh sizes, and
  • material thicknesses.
    Materials available include:
    • Black mild steel,
    • Galvanized steel,
    • Copper,
    • Brass, and
    • Aluminium
        The manufacturing process of expanded metal mesh involves taking a flash sheet of metal which is simultaneously slit and stretched to form a diamond shaped hole pattern.  During the process no metal is lost and the final product is stronger per kilogram and lighter per metre than the original sheet.
