Q235: What is its seismic performance?
A: Strength-to-yield ratio is approximately 1.6~2.1. It has good plasticity and strong deformation capacity, making it suitable for seismic structures.
Q235: What is its heat and corrosion resistance?
A: It is not resistant to high temperatures (strength decreases above 250℃) and is not corrosion resistant. Anti-corrosion measures (painting/galvanizing) are required.
Q235: What steel structural components is it used for?
A: Steel beams, steel columns, roof trusses, purlins, supports, stairs, platforms, and enclosure steel frames.
Q235: Can it be used as reinforcing bars?
A: It can be used as HPB300 (formerly Q235) plain round steel bars for stirrups, stirrup reinforcement, and structural reinforcement.
Q235: What types of steel are it used for?
A: I-beams, H-beams, channel steel, angle steel, flat steel, steel pipes, and steel plates.
