Q235A Applicable Scenarios?
A: Only applicable to static loads, normal temperature, non-welded structures, such as ordinary supports and base plates.
Q235B Applicable Scenarios?
A: Normal temperature welded structures, such as building steel structures and ordinary machinery bases.
Q235C Applicable Scenarios?
A: Low temperature welded structures above 0℃, such as ordinary bridges and factories in northern regions.
Q235D Applicable Scenarios?
A: Important low temperature welded structures below -20℃, such as load-bearing components in extremely cold regions.
How to Choose Q235 Grade?
A: Select A for static loads; B for normal temperature welding; C for 0℃; D for -20℃; C/D grades are preferred for dynamic loads/low temperatures.
