SSAW steel pipe/ spiral steel tube is made of hot-rolled steel plates.
Generally price for SSAW steel pipe is lower than that of ERW steel pipe and LSAW steel pipe when it comes to the same steel grade and standard. SSAW steel pipe is usually used to transfer water, oil, or gas due to the big size.
