In addition to fabrication, APAC can supply raw materials cut to length for your project. The nature of the Australian telecommunications industry often involves buildings comms infrastructure in difficult to access locations, where freighting of pre-built metal structures is not practical or economical. APAC supplies cut-lengths of frame work, such as square hollow section, and fittings to permit the assembly of structures on site.
Grade C450
Grade C450 SHS is a high strength cold formed hollow section manufactured using high frequency Electric Resistance Welding (ERW), and is ideal for general mechanical and light structural applications. The cold-forming process enhances the strength, hardness and surface finish of the tube and produces SHS to tight dimensional tolerances.
