Q235 Carbon structure steel tube

Q235 steel is an ordinary carbon structural steel with a yield value of about 235 MPa, and the yield value will gradually decrease with the increase of steel thickness. Because the carbon content of Q235 steel will be moderate and its comprehensive performance will be better, it is widely used in the construction of plants, bridges, ships, vehicles and so on.
Q235 steel is a Chinese GB standard plain carbon structural steel, it provided in four quality grades: Q235A, Q235B, Q235C and Q235D. 3PE is a coating that usually used to protect carbon steel pipe and prolong their service life.
