Hot Dipped Galvanized Steel Coil

Product Introduction

Hot dipped galvanized steel coil are processed by continuous hot-dip galvanizing from cold-rolled steel coil. Zinc coating on both sides can effectively prevent corrosion and rust, and increase the service life of steel plate.

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%.

Quality Control and Self-inspection

WITOP steel have the advanced testing equipment and professional team. WITOP steel strictly control the quality on each step of production, including inspection on raw materials, product’s thickness and width test, zinc coating test, T-bend test, impact test, tensile test, salt-spray test and package testing on exporting steel coil, which ensures its integrated performance and quality.

Product Application

Hot dipped galvanized steel coil has excellent performance and good comprehensive properties such as corrosion resistance, easy forming and painting. Hot dipped galvanized steel coil are mainly used in build construction, home appliances, containers, transportation,automobiles and metallurgical industries.
Construction industry: roofs, doors and windows, rolling shutter doors, ceiling keels, etc.;
Home appliances: refrigerators, washing machines, air conditioners, range hoods, etc.;
Automotive industry: body shells, chassis, doors, fuel tanks, fenders, etc.;
Metallurgical industry: steel window blanks, color-coated board substrates, etc.
For example, Corrugated Roofing Sheet, Steel Floor Deck Sheet, Ventilation Ducts, U/C Channel, Round/Rectangular/Square pipe, Protection Fence of Highways, Metal Expanded Mesh and so on.

Product Package

Standard export package: 3 layers of packing, inner side is anti-water craft paper, PVC plastic film is the middle and outer side covered by at least 0.45mm thick steel sheet,wrapped by minimum seven steel strapping strips with lock catch.

In particular, WITOP steel places desiccant on the coil inner core side and on both lateral sides of the coil for bulk transportation to ensure that coils are delivered to clients in good condition.

Package can be customized as client’s requirements.
