Dos for Installation
Always wear smooth soft-soled shoes.
Use recommended Personal Protective Equipment (helmet, goggles, shoes, hand gloves & high visibility vests) while handling and installing the sheets.
Remove all metal scrap, drill particles, pop rivet mandrels and excess fasteners from the roof to avoid rust stains.
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 a power saw with a metal-cutting blade to cut thin metals. This results in fewer hot metal particles and leaves less resultant burr than a carborundum disc.
Always place roof screws through the crests. For walling, screws can be either crest or valley fixed.
The groove portion should be on the inner side. The air gap on the left ensures that water does not travel upwards.
Use neutral cure silicone rubber sealants.
Structurals like tubes, HSS, angles and channels should be painted before fixing the sheets.
Use chalk line and fix the screw directly on the supporting members.
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.
Generally, keep your weight evenly distributed over the soles of both feet to avoid concentrating your weight on either heels or toes.
Dont's for Installation
Dont keep colour coated sheets in contact with cement, dirt and chemicals like paint and thinner.
Don't install the roof sheeting during rains, sheets get wet and slippery.
Don't use stainless steel screws, J hook and carbon washer as they may damage the sheet.
Don't overdrive or under drive the screw as it can lead to water leakage or washer damage.
The groove portion should not be on the outer side. Improper contacts makes the roof vulnerable to water leakages.
Don't leave metal articles on the roof.
Don't throw bird feed on the sheet. Birddropping can damage the colour & aesthetics of the sheet.
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.
Don't walk on single rib, sheet, end laps gutter and skylight sheets.
