Instructions for Installation of Sheets

  • Keep your weight evenly distributed over the soles of both feet to avoid concentration your weight on either heels or toes
  • Structure like tubes, truss, angles and channels (except Zinc coated supporting structures) should be painted before fixing the sheets
  • Cut materials on the ground and not on other material where hot particles can fall and cause damage to the finish of the sheet
  • Use neutral cure silicone rubber sealants
  • Immediately after installation / fixing, remove the guard film of pre-painted/ coated sheets. Non-removal of guard may cause condensation of moisture and degradation of inorganic coatings resulting in subsequent paint peel off
  • The rubber washer, component of self- drilling screws must be from materials compatible with roofing, walling and accessory material
  • Iron fines from drilling, saw cut chips & fasteners lying can cause rust stains
  • Leaving debris on the sheets may lead to such type of defects. Sweep, swarf from roof after finishing installation
  • Direct contact with cement foundation is not recommended for bare and pre-painted Galvalume & Pre-Painted Galvanized products. Accelerated corrosion can occur due to the lime contained in the cement
  • Crest fixing for roofs or walls – (A)
  • Valley fixing for walls only – (B)
  • The groove portion should be on the inner side. The air gap on the left ensures that water does not travel upwards –(C)
  • The groove portion should not be on the outer side. Improper contact makes the roof vulnerable to water leakages
  • Remove all metal scrap, drill particles, pop rivet mandrels and excess fasteners from the roof to avoid rust stains
  • It is important that shoes do not have small stones, steel drilling etc. embedded into the soles
  • Two types of dirt accumulate on buildings: dry soil and greasy or organic residues
  • The dry dirt, by itself, washes off with rain or high-pressure water spray
  • Greasy residues do not wash off in rain and hold dry soil and chalk tightly to the surface
  • Water can enter through the guard film, which may lead to paint peel off
  • Proper fastener installation procedures to be followed
  • For roll forming of pre-painted materials, rolls should be properly polished. There should not be any damage on the sheets. Clean the sheets to avoid damage to the paint finish
  • Maintain the roll forming equipment to achieve proper vertical and horizontal tooling alignment, as well as adequate clearance between the mating top and bottom spindle rolls to avoid abrading the coating
  • Guard film should be removed immediately after installation
  • Clean the roof with clean water or mild detergent by using soft cloth, mop or soft nylon bristle brush to avoid swarf stains and rusts
  • Use a power saw with a metal-cutting blade to cut thin metals. This results in fewer hot metal particles and leave less resultant burr than a carborundum disc
  • Metal debris from sawing, drilling and other construction possess should be removed during installation, otherwise, the metal fillings will red rust on the surface where they were deposited. Red rust of the metal filing can cause stain or discolouration on the surface of the panel whether it is bare of painted and cause appearance issue
  • Guard films are provided only for forming operations and avoid handling scratches
  • This water entrapment is because of the capillary actions of the gap between sheet which get entrapped in the packet while stacking/storage
Installation Dont
  • Don’t walk on single rib, sheet, end laps gutter and skylight sheets
  • Don’t throw bird feed on the sheet. Bird dropping can damage the colour & aesthetics of the sheets
  • Do not leave debris on the sheets
  • Do not allow contact with Cement
  • Don’t install the roof sheeting during rains, sheets get wet and slippery
  • Do not allow dirt accumulation on the sheet
  • Don’t use stainless steel screws, J hook and carbon washer as they may damage the sheet
  • The groove portion should not be on the outer side. Improper contacts make the roof vulnerable to water leakages
  • Don’t use acetic acid based sealants which liberate aggressive by-products during curing which is detrimental to steel sheets
  • Never use abrasive or solvent type cleaners and wire brushes, steel wool, sponge scourers to clean the roof sheet as it softens the paint film
  • Do not leave metal filings on the sheets
