Do’s And Don’ts

Transportation
Do’s Don’ts
  • 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’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 Don’ts
  • 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’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 Don’ts
  • 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 climates.
  • 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.
  • 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 Don’ts
  • Use fasteners fittings from Stellar to extend the life of the roof.
  • Don’t use bad quality fittings otherwise corrosion / leakage will occur.
Environments
Do’s Don’ts
  • 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’t use roofing sheets near concentrated sulphur dioxide/chlorine gas, to avoid snowflaking. Natural ventilation in adjoining bays is also very important.
