Transportation

- During transportation, do provide cushioning, by placing straw/thick tarpaulin on the truck bed before loading the roofing sheet, in order to avoid a punching effect from projected bolts/nails.
- Cover the sheets with tarpaulin during the monsoons. Entrapped rainwater can leave watermarks on the aluminium sheet.
- Don't load heavy material on roofing sheets.
- Don't drop the sheets from a height.
- Don't carry alkali materials (cement/fertiliser, etc.) together with aluminium roofing sheets. This may cause a chemical reaction.
Storage & Handling

- Store sheets in a covered shed and cover the stack with tarpaulin.
- Stack the sheets on a batten with a longitudinal slope to allow condensation to drain away.
- In case they get wet, make sure to wipe the sheets dry.
- Handle the sheets with care.
- Don't let water collect between the horizontal sheets, as trapped moisture is likely to cause marks.
- Don't keep too many sheets on one stack. If loose sheets are stacked too high, the bottom sheet will lose its design mould.
- Don't store sheets near alkaline materials. This may cause a chemical reaction.
- Don't drop the sheets from a height.
- Don't place the sheets directly on the mud/cement floor.
Fixing & Layout

- While cutting, use a pencil or a steel point mark and cut along the line with a blade/hacksaw. Ensure that the teeth are fine, in order to avoid uneven edges.
- Lay the starting row sheets at the eaves end with proper alignment of the guide thread.
- Pass the attachments (accessories) through the crowns of the corrugated or troughed sheet.
- Do provide wider ridges/North Light Curves, while keeping sufficient cover beyond the accessories, in order to avoid leakage during the monsoons.
- Paint the purlins before the installation of sheets.
- A coat of aluminium paint on the contact face of the timber is recommended in order to ensure that no interaction occurs, especially due to damp climates.
- Clean the sheet surface after completion of masonry work.
- If you need to walk on the roof, use a cat ladder to avoid dents.
- Avoid bending the sheets sharply.
- Do not cut the sheets with a chisel, as it results in uneven edges and deformation of the profile.
- Do not punch the sheets in order to make holes in them.
Fasteners

- Use aluminium accessories to ensure extended life of the roof.
- Don't use copper/brass/bronze fittings or else bimetallic corrosion will occur.
Environments

- Earth the aluminium sheets correctly. Aluminium offers protection from lightning damage, due to its high electrical conductivity.
- Ensure the use of aluminium conductors.
- Ensure that the design includes proper ventilation and sufficient sloping of the roof. This is necessary to avoid condensation.
- To avoid snowflaking, don't use aluminium sheets near concentrated sulphur dioxide/chlorine gas. Natural ventilation in adjoining bays is also very important.
