Care must be taken to ensure that RIVER BRAND roofing sheets are stored in a well ventilated area. This is to avoid accumulation of moisture on the roofing sheets and to avoid contact with or exposure to any corrosive agent such as chemicals, solvents of noxious vapors. To protect the surface and personal safety, Roofing / Cladding sheets should only be handled using clean dry gloves. The sheets should not be dragged over rough surfaces or on each other, nor should tools be dragged over the sheeting. If bundles become wet, the sheet should be separated, wiped with a clean cloth and stacked so that air circulation completes the drying process.



When walking on the Roofing Sheets, keep weight evenly distributed on sole of the feet. Use soft soled shoes to walk on roofing. Sheets taken newly from packs may be slippery and care should be taken when walking over them until the rolling oil has evaporated.



When cutting roofing sheets with a power saw, care should be taken to protect the material. Whenever possible, cutting should be done on the ground and not over other coated materials. Sheets should be placed face down on padded supports to reduce damage of the surface. Metal cutting blades are preferred to carborundum discs as they produce fewer damaging hot metal particles and leave less burr with no burnt edges on the cut sheet.

Majority of roof rust are due to inferior quality metal fasteners. It is important to select good corrosion resistant self- drilling hexagon head roofing fasteners with neoprene washers.



As it is not practical to solder coated steel, where sealed joints are required, use screws or rivets and silicone sealant.



Normal installation practices such as drilling, cutting, etc. usually leave metallic dust on or around the roof areas. This material and all other debris, including blind rivet shanks, nails, screws, etc., should be swept from the roof area and gutters regularly, certainly at the end of each day’s work, and particularly on completion of the installation. Failures to do so can result in unsightly staining to the surface as the metal particles oxidise. Corrosion and possible failure of the Zinc Aluminium coating may occur when steel, lead or copper based materials are left in contact with coated steel and moisture.
