General Information About Site Storage
Here are some tips regarding site storage that can assist you when planning and carrying out your next project.
- Storage time should be minimized by installing cladding panels as soon as possible after delivery. Good planning will ensure that panels are used on a first-in first-out basis.
- If cladding must be stored for an extended period, the most desirable storage place is under-roof in a cool, dry, well ventilated area
- When storing outdoors is unavoidable, the following is recommended:
- Use good covers, loosely shrouded over stacks and firmly anchored to prevent wind blow off, but plastic covers should not be used for storage
- Tilt bundles for drainage
- Ventilate bundles but do not allow entry of wind-driven rain
- Block bundles off the ground for effective drainage and ventilation
- Block long panels to prevent sagging
- Store out of direct sunlight if possible
- Store away from chemically aggressive substances (e.g. salt, cement, fertilizer), away from material that could contaminate the surface (e.g. diesel oil, paint, grease) and away from site traffic.
- Shipments of bundled cladding panels should be inspected upon delivery.
- Moisture can cause wet storage staining of pre finished material and usually occurs in one of three ways:
- Condensation from high humidity and/or temperature cycling;
- Wet shipping conditions; or
- Wind-driven rain penetration (outdoor storage).
The usual progression is from visible water staining to unsightly white staining (dark grey to dull black on aluminum-zinc alloy coated material) to red rust. On material where wet storage staining has occurred, it should be noted that a nominal amount of white staining is not detrimental to the functioning of the product and is usually considered acceptable.
