Description

Factory price mechanical properties spiral welded steel tub with high quality

EN10305-2 Cold Drawn Welded Precision Steel Tubes DOM tubing E155,E195,E235,E275,E355 +C +LC +SR +A +N

DOM is a process that is applied to tubing after it is initially constructed.It is refferred to as Seamless ,It can be said that do seamless process method on ERW tubes,So the tubes will have a high strength ,high quality .Material form E155 E195 E235 E275 E355 1020 1026 and so on .DOM tubing is commonly use in auto parts .
