We can supply as follows:
• Plain stainless steel sheet, polished or stucco embossed 0,40-0,80 mm
• Plain aluminium sheet 0,50-1,00 mm
• Stucco rolled aluminium sheet 0,50-1,00 mm
• Plain Aluzinc / Galvanized / T2 Aluminized steel sheet 0,40-1,00 mm
• Paint coated Stainless Steel / Aluzinc / Galvanized steel sheet 0,40-1,00 mm
Material can also be supplied with a factory applied bonded Surlyn moisture barrier (DryMet) this is fixed to the underside to prevent corrosion especialy for use in industrial insulation.

Due to the processing demands these products are manufactured to order and minimum quantities are required, these may vary dependent on selection but typically no less than 250 m2. Generally its more economical to produce quantities of 500m2 upwards.
Our round corrugation can generally be produced in smaller quantities this can be found here.
