Supa-Tile Roofing Sheet 0.30mm x 6.0m Supa Red
Product Description
Super premium appearance of tiles.
With the strength and light-weight advantage of steel, Supa-TILE is a durable, cost-effective, pre-painted roofing sheet. The profile looks like roof tiles, but is as strong as steel. The paint system used on it provides optimal performance and is excellent value for money. Inspired by the vibrant colours of Africa, Supa-TILE is produced by a unique process whereby rolled steel is continuously hot dipped into a patented alloy of 55% aluminium, 43.5% zinc and 1.5% silicon.
This patented coating protects the stell in two ways:
• The aluminium component of the coating provides a tough physical barrier between the external atmospheric conditions and the inner core of steel.
• The zinc in the coating sacrifices itself to protect the steel at cut edges.

PRODUCT CARE/STORAGE
Care and storage:
• Keep your Supa-TILE roof sheet dry at all times.
• If the roof sheet is to be stored, it must be stored in a cool dry environment, with the protective packaging.
• Projects more than 5 km from the ocean or 5 km from a highly industrial environment require a 6-monthly wash down. Projects less than 1 km from the ocean or 1 km from a highly industrial environment, and projects with auxiliary installations, require a 4-monthly wash down.
• All wash downs need to conform to our recommendations as detailed in our “Recommended cleaning procedures for coated steel sheeting” guidelines.“
Welding:
• Resistance spot welding, projection welding, fusion welding, MIG, and TIG welding are recommended at the relevant settings.
• Resistance seam welding is not recommended.
• Projects more than 5 km from the ocean or 5 km from a highly industrial environment require a 6-monthly wash down. Projects less than 1 km from the ocean or 1 km from a highly industrial environment, and projects with auxiliary installations, require a 4-monthly wash down.
• All wash downs need to conform to our recommendations as detailed in our “Recommended cleaning procedures for coated steel sheeting” guidelines.“
Fasteners and accessories:
• All screws should have rubber sealing washings which should be free of carbon fillers.
• Fasteners should be as durable as the roof sheeting.
• A minimum class 3 should be used for all Supa-Roof steel.
• If an inferior class fastener is used, the replacement of the sheet will be at an earlier interval.
General notes:
• Touch up paint is not recommended.
• Never use abrasive or solvent type cleaners.
• Don’t use rough cleaning cloths, wire brushes or steel wool to clean the roof.
• Supa-Roof steel is compatible with other materials such as aluminium, galvanised, or equivalent aluminium/zinc coated steel; however it is advisable to avoid mixing different types of material on one project to prevent the possibility of corrosion.
