1.Primary color steel strap is also called the white packing steel strap, and the white color is the bright primary colors after
cold rolling. They needn't do any other surface treatment, only need coat a layer of anti-rust oil. This kind of packaging with
low price, some foreign countries used them as building material and in general their dosage is very large. Commonly, it adopts 3-4 layer packaging, or packaging according to customer requirements.

1. Bluing steel strapping is to heat treatment the steels at about 200 degree centigrade and make the steel surface to form a yer of dense ferroferric oxide film. Its main ingredient is ferroferric oxide
2. Paint steel belt is a new type used for strapping cargo packing belt, it has better performance in all aspects than other common steel belts. Firstly, embodied in the painted steel belt won't appear rusty phenomenon, it does not like ordinary steel belt packaging rusty spot goods, more environmental protection. Secondly, painted steel belt after cold rolling, shearing, bluing or paint or galvanized, and so on, the finished good elongation, tensile strength, the goods strapping compared strong trust, this is also why painted steel belt is more and more popular.
3.Galvanized packing steel straps adopt ordinary carbon structural steel or high quality carbon structural steel, through cold
rolled, electric blue and galvanized. Galvanized steel strip is bluing further deep processing of steel belt, this product is on
the basis of bluing steel straps to do the galvanized processing, solved the problem of the steel strip rust. It is Suitable for
the packing of wood, paper, glass, stone, steel strapping packing, welded pipe and other large objects.
