General The Aardwolf bundle racks consist of a pair of galvanized steel rails 3m long, together with rectangular galvanized steel tube posts (these posts are to be sold separately). The rectangular post can be positioned anywhere along the rack. All posts are manufactured from rectangular tube steel with a minimum yield strength of 345Mpa, with 5mm wall thickness, ensuring safety for the vertical storage of slab bundles. Features The maximum number of marble or granite slabs that can be safely stored per bay at a 4° lean depends on the slab thickness and dimensions . Aardwolf has developed a simple calculator specifically to calculate the slab storage capacity. Post available in 3 standard heights of 1200mm, 1400mm, 1600mm.
