Always work safety when installing metal products and use extreme caution on the roof at all times. Wear gloves and safety glasses to reduce the risk of injury, and use hearing protection when operating power tools. Alaways wear smooth soft-soled shoes; avoid ribbed soles that pick up and hold small stones, swart and other objects.


Store metal panels indoors when possible; if outdoors; cover and elevate. Elevate one side higher for water drainage. Never cover in plastic. If a bundle gets wet, break bands and separate sheets; allow sheets to dry completely and only restack if completely dry. Material should be used promptly (within 3 months) to avoid the possibility of a storage related corrosion.


It is recommended that heavy-duty cut-resistant gloves and appropriate manual handling techniques or a lifting plan be used when handling material. Handle materials carefully to avoid damage: don't drag materials over rough surfaces or each other; protect from swarf.
