Hi-tensile Steel Wall Cladding
LengthMetroll can supply Metroclad 850 Colorbond® or Zincalume® sheeting up to a maximum length of 6 metres depending on load limit regulations set by the relevant local transport authority. Lengths ordered to be manufactured by Metroll must be site measurements, not those taken off plans. Length tolerance on Metroclad 850 is ± 10mm. Width tolerance on Metroclad 850 is ± 5mm.
Availability & Delivery
Metroclad 850 is available direct from Metroll or their distributors. Prompt and efficient delivery is assured. Please contact your local Metroll office or distributor for the relevant delivery days to your area. You can help us to supply you with materials in good order by ensuring that you have made suitable arrangements to have our trucks unloaded. To prevent damage when lifting long lengths of sheeting by crane, please take care to ensure that the load is spread. Where a crane cannot be made available it is the customer’s responsibility to provide sufficient labour to assist the driver in unloading.
Handling of Material
When handling Metroclad 850 care should be taken at all times to preserve the quality of the finish. Packs should be kept dry and stored above ground level whilst on site. If however the sheets do become wet they should be separated, wiped and placed in the open to dry.
Cutting
Metroclad 850 roof sheeting can be cut where necessary by using a circular saw with a metal blade, not an abrasive disc. When you cut Colorbond® sheeting ensure the coloured surface is placed downwards to lessen the likelihood of swarf (hot metal filings) being embedded in the exposed roof surface.
The Product
