There are two types of hot dipped aluzinc steel coil. One is hot dipped aluzinc steel coil raw sheet. One is anti-finger hot dipped aluzinc steel coil. Know as CAMESTEEL, most of the material is anti-finger sheet hot dipped aluzinc steel coil. And the so-called anti-finger galvalume steel sheet/coil is very nice.
After the aluminium and zinc galvanization, people do a surface manage, which could not only protect its surface during the Al-Zn alloy coated steel sheets productive process, but also postpone its corroding time. And anti-finger is very important, especially for the steel structure roof or metope.
As the anti-finger galvalume steel sheet/coil, when it is dirty, people could wipe and clean it which will not damage galvalume steel sheet/coil surfaces’ cladding material. And it could reduce the cost effectively.
As it is used widely, galvalume steel sheet/coil surfaces’ anti-finger technique becomes more advanced. And the function has developed from the original surface protection to antisepsis.
