The Base Metal:

To ensure the maximum protection against the elements, our base metal is cold rolled, electro galvanised hot-dip aluminium-zinc (55% Al-Zn) coated steel sheet.

The hot-dip alu-zinc coated steel sheet gives 2 to 5 times the corrosive resistance of the standard hot-dip zinc coating.

The colour is stable up to ambient temperatures of 316 degrees centigrade. While being free of oxidation or oxide scaling up to temperatures of 490 degrees centigrade.

Heat and light reflected off the steel is twice that of hot-dip zinc, with a reflectivity exceeding 0.75, easily surpassing the 0.65 required by the EPA Energy Star Standard.

Our cold rolled hot-dip Al-Zn steel sheet is the perfect material for the construction industry, coupling high resistance to corrosion and long lasting durability of colour, with excellent insulation and energy saving qualities.

Insulation materials:

We offer a choice of three insulation materials.

Polyurethane: This is the material used in all our basic twin walled insulated sheets. It comes in a choice of thicknesses dependant upon the U value required on any given building, from 25mm to 150mm. Polyurethane offers the best thermal qualities, for the lowest section of all our insulated sheets.

Rock-wool: This is the insulation material of choice where environmental considerations take precedent over thermal performance and structural integrity. It is completely environmentally friendly, and easy to handle. However, on average, the wall and ceiling panels will be approximately twice as thick as Polyurethane to achieve the same thermal performance. It is cheaper than Polyurethane, but costs more to ship due to its higher volume, so usually the higher shipping cost cancels out the lower material cost.

Expanded Polystyrene (EPS): This insulation material is cheap, very light, provides excellent thermal insulation and structural performance coupled to a very long life. It also has excellent sound-proofing qualities. In the right building, it could be precisely the insulation material of choice. It is not recommended for use in high density urban areas, due to the emission of toxic fumes if burned.
