a means when the thickness is more than 1.5mm, the minimum value r90 can lower 0.2.
b means when the thickness not more than 0.7mm, the minimum value r90 can lower 0.2, n90 can lower 0.01.
c means For difference thickness of coating products, thick coating surface as the outer surface of the bending test.
DC52D+ Z is same with the grade St01ZR, St01ZR is an old grade and we usually use DC52D+Z now. As a professional galvanization factory, BEBON can supply the material DC52D+ Z, DC52D+ZF according to your requirement. If you have need for them, BEBON is your right choice.
