More and more High Bay warehouses of 16 to 40 m (50 to 130 ft.) in height are being built and are directly associated with the use of automated stroage and retrieval systems (ASRS). The number of Distribution Centers (D.C.) are very much on the increase and are taking full advantage of the totals systems available from TRAVHYDRO. TRAVHYDRO also provide the structural engineering support to provide a "design and build" Rack Clad Building i.e. roof and wall-supporting frame storage structure. This steel construction is designed to meet the local conditions of wind forces, seismic forces and to the meet the required firee regulations. Based on the use of cold-rolled sections whose strict limits in tolerances are widely recognised, the advanced design and latest manufacturing technology used in the TRAVIRACK welded upright profile as well as the experience of over 70 years in scaffolding and steelwork, is a record of excellence to be considered when storage solutions are required to meet the operational demands placed on supply chains ans especially when the compliance with very accurate manufacturing and installation tolerances are critical.
