COLORBOND® Permagard® steel

COLORBOND® Permagard® steel has been specially developed for the manufacture of coolroom panels.

Its baked on paint finish resists peeling, flaking and blistering in normal weather conditions, and features an antibacterial property that provides excellent benefits for the food industry.

What's a coolroom panel?

Insulated panels for cold storage and other temperature controlled environments typically comprise two sheets of COLORBOND® Permagard® steel adhered to an inner foam core.

The core can be either expanded polystyrene or polyurethane, depending on the application or the design requirement.

These panels are manufactured by specialist producers across Australia using continuous forming equipment to create a rigid panel (although non load bearing).

Panel thicknesses range from 50mm to 200mm.

Coolroom Panels made from COLORBOND® Permagard® steel

Panels made by bonding COLORBOND® steel with an insulating core have been the industry standard for walls and ceilings of temperature controlled environments for many years. Insulation performance, durability, speed of construction, spanning capability, ease of cleaning and light reflection qualities are just some of the reasons.

COLORBOND® Permagard® steel, with its superior antibacterial performance, has raised the industry standard to include greater hygiene and the reduced risk of cross-contamination.

COLORBOND® Permagard® steel provides exceptional corrosion resistance.


  • Reduces risk of cross-contamination
  • Helps to protect difficult to clean areas
  • Enhances antibacterial protection between cleanings
  • Tested effective against Staphylococcus aureus and Escherichia coli 0157
  • Antibacterial protection does not wash off
