List four requirements when storing large quantities of sheet materials.
Correct storage is important for all wood-based panels.
Care is needed to avoid (1) mechanical damage to panel edges and corners and to (2) avoid damage from wetting or high humidity or (3) injury to the persons undertaking the storage and handling operations. Storage on site (4) Panels must be protected from rain and direct wetting at all times
Prevent damage to the sheets
Correct Storage
Stacking
Panels should be stacked flat on a level surface with all four edges flush. The panels should be sufficiently clear of the ground to avoid any potential splashing from water on the ground. Stacking of panels on edge should be avoided, whenever possible. The ideal base for the stack is a close boarded or slatted pallet. If this is not possible, then the panels should be carefully stacked on battens of equal thickness at centres not exceeding 600mm, as shown.
Where space will only permit stacking on edge, then the edges should not be permitted to come into direct contact with the ground or floor to avoid any possible moisture pick-up or damage to the edges. Panels should not be leant against walls but should be supported by a braced, purpose-made stack using thick (>18mm) base and back panels as shown.
Handling
When lifting, moving and stacking panels, edge protection should be provided to avoid damage by lifting ropes and/or forklift tines.
When handling pre-finished panels, it is essential to avoid damage or dirt on the finished surfaces. Pre-finished panels should be lifted from the stack and not slid
Storage on site
Stacking of panels on site should be in accordance with the recommendations given above.
Panels must be protected from rain and direct wetting at all times.
