the advantages of galvanized steel coil are mainly manifested in the following aspects:

1.Processing performance
Hot dipped galvanized steel coil can fully meet the requirements of rolling, stamping, printing, marking, bending and other forms of processing.

2.Corrosion resistance
Hot dipped galvanized steel coil has excellent corrosion resistance, and the service life is 3 times than that of hot rolled and cold rolled steel under the test of the same thickness and surface treatment.

3.Heat resistance
Hot dipped galvanized steel coil can be used for a long time in an environment of 315 degrees without changing color while other steel sheets are just used at a temperature of only 230 degrees, and 250 degrees will change color.

4.Mechanical properties
the mechanical properties of galvanized steel sheets are significantly higher than those of hot rolled and cold rolled steel sheets, which are mainly manifested in yield strength, tensile strength, and elongation. the yield strength of galvanized steel sheet is between 300 and 400mpa, the tensile strength is between 300 and 550mpa, and the elongation is between 28% and 40%.

FAQ of Hot Dipped Galvanized Steel Coil

1.Is hot dipped galvanized steel same as galvanized?
Hot-dipped galvanized steel is a type of galvanized steel. Hot dipped galvanizing process is practical, and hot dipped galvanized product is very durable, versatile and highly corrosion-resistant.

2.What is the difference between G60 and G90 for galvanized steel?
G90 galvanized steel are coated by the coating weight of zinc 0.90 oz/ft^2 while G60 galvanized steel are 0.60 oz/ft^2. that is to say, G90 galvanized steel are coated by the weight of zinc 275g/m^2 while G60 galvanized steel are 180g/m^2.
Therefore, G90 galvanized steel are more 95g/m^2 zinc coating than G60 and then a longer service life.

3.What are galvanized steel coil used for?
Hot dipped galvanized steel coil are most produced to roofing sheet for construction, home appliances, containers, transportation, automobiles and metallurgical industries.

4.how are galvanized coils made?
Hot dipped galvanized steel coil are made from cleaning and heat-treating cold rolled coils and then are zinc coated from zinc pot. through this process, cold rolled steel coil are plated with zinc for anti-rust.

5.how long will galvanized steel coil last?
the zinc coating of hot-dipped galvanized steel will last 10 to 30 years in the open environment. High humidity and temperature have less life time for galvanized steel coil.

6.Does galvanized steel rust?
Galvanized steel coil will take 10 year or more to rust, but it will eventually rust. Galvanized steel coil the layer of zinc on both sides. Which can resit rust acts by preventing oxygen and water from the steel.

 

What is 28 Gauge?

Are used to specify the thickness of the sheet metal. Gauge is neither standard nor metric, and its values are independent of those measurement systems. Generally speaking, for the same material, the higher the number, the thinner the sheet of metal.

the term " 28 gauge" refers to the thickness of the steel sheet. in the , a higher number indicates a thinner sheet. Specifically:

• 28 Gauge Thickness: Approximately 0.0157 inches or 0.40 millimeters.
