What are the core advantages of Q195 steel coil?
Excellent plasticity/weldability, easy cold forming, low cost, complete specifications, and stable supply.
What are the main disadvantages of Q195 steel coil?
Relatively low strength, poor corrosion resistance, requires anti-corrosion treatment in humid/acidic/alkaline environments, and is not suitable for heavy-duty structures.
In which scenarios is Q195 unsuitable?
High-strength load-bearing structures, high-pressure vessels, low-temperature impact, and highly corrosive environments require Q235 or higher, or alloy steel.
What is the difference between Q195 and DC01 (cold-rolled low-carbon steel)?
Q195 is a national standard structural steel, emphasizing strength and weldability; DC01 is a European standard deep-drawing steel, with superior deep-drawing performance, suitable for complex stamped parts.
How to choose the surface and thickness of Q195 steel coil? For high appearance/precision requirements, choose cold-rolled bright finish; for corrosion resistance, choose galvanized/painted finish; for heavy loads, choose thicker specifications (≥3mm); for light loads/stamping, choose thinner specifications (0.5-2mm).
