Do’s And Don’ts


• Transportation

• Do’s
» During transportation, do provide cushion with straw/thick tarpaulin on truck bed, before loading the roofing sheet in order to
avoid punching effect from projected bolts/nails.
» Cover the sheets with tarpaulin during monsoon. Entrapped rainwater can leave watermarks on the roofing sheet.
• Don’ts
» Don’t load heavy material on roofing sheets.
» Don’t drop the sheets from a height.
» Don’t carry alkali materials (cement/fertilizer, etc.) with roofing sheets. This may cause a chemical reaction.


• Storage & Handling

• Do’s
» Store sheets under 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.
» Wipe the sheets dry, in case they get wet.
» Handle the sheets with care.
• Don’ts
» Don’t let water between the horizontal sheets, 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 keep the sheets directly on the mud/cement floor.


• Fixing and Layout

• Do’s
» For cutting, use a pencil or a steel point mark and cut along the line with a blade/hacksaw. Ensure that the teeth are fine, 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 keeping sufficient cover beyond the accessories, in order to avoid leakage during the
strong, windy rains.
» Paint the purlins before the installation of sheets.
» Roofing Sheets paint on the contact face of the timber is recommended in order to ensure that no interaction occurs during damp
» Clean the sheet surface after completion of the masonry work.
» If you need to walk on the roof, keep the cat ladder to avoid dents.
• Don’ts
» Avoid attempts to sharply bend the sheets.
» Do not cut the sheets with a chisel as it results in uneven edges and deformation of the profile.
» Do not punch for making the holes.


• Fasteners

• Do’s
» Use fasteners fittings from Stellar to extend the life of the roof.
• Don’ts
» Don’t use bad quality fittings otherwise corrosion / leakage will occur.


• Environments

• Do’s
» Earth the roofing sheets correctly. Roofing sheets offers protection from lightning damage, due to its high electrical conductivity.
» Use only roofing sheets conductors.
» Ensure that the design includes proper ventilation and sufficient sloping of the roof. This is necessary to avoid condensation.
• Don’ts
» Don’t use roofing sheets near concentrated sulphur dioxide/chlorine gas, to avoid snowflaking. Natural ventilation in adjoining bays
is also very important.
