Hot finished structural hollow sections
Hot finished structural hollow sections are tubular products produced from steel coils. The coil is slitted to strips with appropriate width and then formed by rolling into the shape of the tubular product. The two strip edges, now lying next to each other, are welded together using a high frequency induction process. Further sets of rolling gives the final shape and size of the cold formed hollow section, and after trimming of the external weld bead and non-destructive testing, the tubes are cut to length prior to hot finishing. The subsequent hot finishing process comprises a reheating operation, and with the section at a normalising temperature of approximately 900 degrees Celsius, a further shaping and sizing operation imparts the product’s final dimensions and properties
before despatch.
