FAQ

What is Q235 carbon steel?
Q235 carbon steel is a common ordinary carbon structural steel, also known as A3 steel, which can be divided into four grades: A, B, C, and D. The "Q" in Q235 represents the yield limit, and the following 235 indicates that the yield value of this material is approximately 235 MPa. Due to its moderate carbon content, good comprehensive performance, and excellent strength, plasticity, and welding properties, it is widely used in fields such as construction and engineering structures, vehicles, boilers, containers, ships, etc
How to Choose: q235 galvanized pipe VS Q235 Black Pipe
If it is for outdoor use or in some special acidic or alkaline environments, choosing Q235 galvanized pipe is more corrosion-resistant. Q235 Black Pipe has weaker corrosion resistance than galvanized pipe due to its untreated surface.
Is q235 steel tube Sample Free?
Yes,Yuantai Derun Can supply you free Q235 steel pipe samples,but the length must be within 20CM.You only have to pay the shipping fee.
