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.

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.

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.
