B490NQR anti corrosion structural steel coil has added phosphorous which makes the material best suited for gas flue applications and for aesthetic facials The material is not recommended in heavy load bearing applications – in this case B490NQR anti corrosion structural steel coil should be considered.With alloy element, such as Cu, Cr, Ni , added , the anti corrosion structural steel acquires a corrosion resistance ability and extends the service life.
B490NQR Hot rolled steel coil improved anti corrosion structure steel plates have better corrosion resistance than carbon steel plates in the atmosphere. With time passing by, once installed, B490NQR improved anti corrosion structure steel plates can gradually formed a protective layer of rust resistance to atmospheric corrosion.
