The protective nature of both the zink and paint coatings of steel sheeting can be seriously impaired when exposed to wet conditions for extended periods of time in absence of air flow.
The zink surface becomes susceptible to corrosion during prolonged storage without the necessary precautions.
To prevent unnecessary damage to galvanized, zinkal and colour coated coil or profiled sheets, special precautions should be introduced to eliminate contamination by moisture.
If galvanized,zinkal and colour coated coil or profiled sheets are not required for immediate use, coils or packs of sheets must be stored off the ground on site under properly designed cover, protected from wind driven rain. Plastic tarpaulins that completely envelop packs of sheets or coils should not be used, because a sudden drop in temperature may result in the formation of condensation or water vapor which can easily be drawn in between nested sheeting by capillary action.

• ProTile 700 is a very rigid span and the absence of flat areas completely eliminates oil canning.
• ProTile 700 is durable and light weight, and can be accommodated with a lighter roof structure which adds to reducing costs.
• ProTile 700 covers a wide area and is aesthetically pleasing.
• Due to the pressed in profile, ProTile 700 cannot be factory-cranked or curved.
ProTile 700 is ideal for residential applications due to the popularity of standard roof tiles, with the added benefit of being durable and light weight in the steel roof sheet form. ProTile 700 also appeals to commercial applications where aesthetics is important.
