Preparation for installation of sheets.

Please ensure the following before the installation of roofing sheets.

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.
The rubber washer, component of self- drilling screws must be from materials compatible with roofing, walling and accessory material.
Use neutral cure silicone rubber sealants.
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.
Don’t install the roof sheeting during rains, sheets get wet and slippery.

Fixing instructions for sheets.

Please ensure the following at the time of installation of roofing sheets.

Keep your weight evenly distributed over the soles of both feet to avoid concentration your weight on either heels or toes.
It is important that shoes do not have small stones, steel drilling etc. embedded into the soles.
Crest fixing for roofs or walls. Valley fixing for walls only.
The groove portion should be on the inner side. The air gap on the left ensures that water does not travel upwards. The groove portion should not be on the outer side. Improper contacts make the roof vulnerable to water leakages
Proper fastener installation procedures to be followed
Don’t use acetic acid based sealants which liberate aggressive by-products during curing which is detrimental to steel sheets
Do not allow dirt accumulation on the sheet

Please ensure the following post the installation of roofing sheets.

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.
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
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
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.
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.
