Floor depth 16.5mm approx.3-4mm Stone size 2.5m length RAL Colours These Aluminium profiles are made for particularly highly stressed floors. For example, the expansion joint profiles are suited for warehouses and production floors, underground garages and shopping centres as well as any floors that are to be cleaned using machines. The visible surface of the profile is 10 mm. Both legs are equipped with an EPDM expansion zone. The specially developed expansion joint profile absorbs heavy stresses and spreads them evenly throughout the flooring and the foundations. It also prevents transmission of footfall and sounds from other objects. Important: any expansion joints in the foundations need to be followed precisely. Properties: Aluminium profiles may be used wherever unusual chemical reactions are not to be expected. To avoid corrosion, it is necessary to take care with cement materials. Since aluminium is susceptible to alkalis, any mortar, tile adhesive or grout residues must be removed immediately from all visible surfaces. The profile must be completely embedded in the contact layer. This avoids the formation of pockets where alkaline solutions of water can collect.
