The High Density system is available in stainless steel, aluminium and aluminium/plastic. Such a system increases the storage capacity by up to 40%. The systems are available as single and double racks with screwed cross connectors to make optimum use of the rack depth without cross braces. High-quality rollers on rails (these do not have to be bolted to the floor) guarantee easy movement of the racking units. The mobile racking system can be assembled without any problems, whereby an even floor surface is the prerequisite.
