The better care you take of your panels, the longer they last. Careful site handling includes • Store formwork panels on flat, level, dry ground • Protect them with a waterproof covering • Avoid storing panels in very hot and dry places • Avoid direct sunlight to prevent panels from twisting and panel surfaces to be damaged If conditions are humid, remove strapping to prevent expansion damage. Note that overlaid panels are extremely slippery - after strapping has been removed, panels should not be moved using mechanical moving • Finnforest formwork panels can be cut, shaped and drilled...
