Galvanized Steel Coil
DX56D Galvanized Steel Coil

Galvanised steel is represented by cold- and hot-rolled coils with a zinc coating, which helps to protect the steel against atmospheric corrosion. Galvanised steel coils are successfully used in industries with stringent requirements for corrosion resistance, durability, strength and appearance, and can be formed or have various coatings applied.

Advantages

·Excellent anti-corrosion, paintability, and processability due to the self-sacrificing characterisiticof zinc.

·Available to select and produce the desired amount of zinc gilded and in particula enables thick zinc layers.

·Classified as either zero spangle or extra smooth depending on wheteher the sheet undergoes skin pass treatment.

Application of galvanised steel coils

Galvanised steel coils are widely used in the following industries: 

In the construction industry: to manufacture structural elements low-rise construction, light steel thin-walled structures, sandwich panels, lining of heat pipelines and various heat insulation, conditioning systems, metal roof shingle, profiled sheeting, culvert pipes, cladding of entry doors, elevators, reinforcement profiles for PVC windows and plastic doors, European-type fasteners for plasterboards, etc 

In the automotive industry: to manufacture external and internal car body parts, as well as to repair external public transport body parts, eg for buses and trams) 

In the machine building and instrumentation industries: to manufacture cases for electrical and mechanical equipment, home appliances, metering devices and packing 

To manufacture houseware (tableware, bowls, buckets, tanks, baths, etc) 

To manufacture colour-coated (and other type of coating) rolled steel
