Longitudinally Welded Steel Pipe (LSAW)
As spiral pipes are made from coils, there is a limitation to the thickness it can be produced. Longitudinally welded pipes such as LSAW (JCOE) are able to achieve up to 50mm thickness. However as these pipes are rolled from plates, the longest length possible is 18m.
High Frequency Welded Pipe (HFW)
Due to its ability to be welded to small dimensions, HFW pipes are particularly suitable for roof trusses, stadiums, bridges and other structural applications.
