Galvalume Coil

The surface of the galvalume steel plate is a unique smooth and flat star flower, the basic color is silver, and the coating is composed of 55% aluminum, 43.4% zinc and 1.6% silicon, which are dried at a high temperature of 600 ° C to establish a high-density quaternary Crystals, eventually forming a strong and effective natural barrier to prevent the penetration of corrosion factors.

PRODUCT DETAILS

The corrosion resistance of galvalume mainly comes from the barrier protection function of aluminum and the sacrificial protection function of zinc. When zinc is used for sacrificial protection in trimming, scratches and scratches of the coating, aluminum will produce an insoluble metal oxide layer, giving full play to the role of natural barrier protection.

The advantages of galvalume compared with ordinary hot-dip galvanizing:
1. Corrosion resistance: Tests under the same conditions show that the service life of galvalume steel sheets is about 2-4 times that of galvanized steel sheets.

2. Heat reflection: The heat reflection of galvalume steel plate is very high, which is twice that of hot-dip galvanized steel plate. It is suitable for use as heat insulation material and metal roof of steel structure, which can achieve the actual effect of environmental protection and energy saving.

3. Heat resistance: galvalume steel sheet can be suitable for low temperature environment up to 315°C. Generally, the use scene of hot-dip galvanized steel sheet should not exceed 230°C.

4. Scratch resistance and easy processing: the strength of galvalume coating (100-110HV) is twice that of general hot-dip galvanizing (55-65HV). The galvalume steel plate is a fingerprint-resistant surface, so it is not easy to damage during the cold drawing process, and the surface of the finished product is more beautiful.

Factory Appearance

Galvanized steel coil, immersing the thin steel plate in the molten zinc bath, adhering a layer of zinc
thin steel sheet on the surface.It is mainly produced by continuous galvanizing process, that is, the
coiled steel plate is continuously immersed in the zinc-melted plating tank to make galvanized steel
sheet; alloyed galvanized steel plate. This kind of steel plate is also made by hot dipped method,
but it is heated to about 500 ° C immediately after exiting the tank to form an alloy film of zinc and
iron.This galvanized coil has good paint adhesion and weldability.
Hot-dip galvanizing is the reaction of molten metal with an iron substrate to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle iron and steel parts first. In order to remove iron oxide on the surface of iron and steel parts, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed solution of ammonium chloride and zinc chloride. And then sent to the hot-dip plating bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

Packing and shipping
The sheets is packed with PVC film or water-proof kraft in the first layer, the second layer is iron sheet package, then wrapped
on the metal pallet or metal square tube with steel strip.
It's is water-proof and sea-worthy, and warmly welcomed by the customers. besides,the pakage can also be according to
your demands.
Shipping
1. Shipping by containers
2. Shipping by bulk ship.

Application area

Galvanized sheet coil is produced by continuous hot dipped galvanizing process with hot rolledor cold rolled steel strip as substrate.Hot dip galvanized sheet supplied by cutting across rectangularplates;and hot dipGalvanized Coil supplied by coiling Galvanized sheet coil can be divided into hot rolled galvanized sheet coil and cold rolledhot-galvanized sheet coil, their characteristics are:Corrosion Resistance, good surface quality, benefit from deep processing,economic and practical, etc.
Galvanized Steel Coils are produced through a process of metal coating which involves passing could rolled coils through a kettle containing molten zinc. This process ensures adhesion of zinc to the surface of the steel sheet. The Zinc Layer provides excellent corrosion resistance and prolong service life.
Hot dipped galvanized products are widely used in hosehold appliances, transort, container manufacturing, roofing, base material for pre-painting, ducting and other construction related applications.
In the automotive industry: to manufacture external and internal car body parts, as well as to repair external public transport body parts, for buses and trams.
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 elevators,etc
