Product description

Hot-dip Galvanized Steel  Coil  (GI )

Aluminum-zinc Galvalume Steel Coil (GL) 

The properties of hot-dip galvanized steel are tough coating, completed protection, less maintenance and long life.

Hot-dip Galvalume Steel combines utility with beauty. It consists of tin, chrome, zinc or paint, which are the extra finish applied to the natural steel surface. The application of coating is to protect the surface of steel from oxidation and it is also used to enhance requirements for visual appearance.

Application

Hot dip galvanized steels is specified for optimum corrosion protection and enhanced aesthetic appeal. Typical residential uses for galvanized steel include doors, window hoods, gutters, downspouts, etc.

Hot-Dip Galvalume Steel Coils has excellent heat resistance durable ability and anti-oxidation performance. They will not leech into the water and mud with higher corrosion resistance. Hot-dip galvalume steel coils is the ideal steel materials for water heating machines, food dehydrators, exhausted tubes, automobile mufflers and structural sections.

Quality control

  • Surface test .

  • Salt spray test is srtificial salt spray environment ,simulate marine climate ,used o check Anti salt spray

corrosion performance of GI and PPGI ,and evaluate the quality of the protective coating process  .    

    A salt spray test is a corrosion testing method that uses high-saline environments to measure the corrosion resistance of products, paints and coatings over extended periods.

  • Flexibility Impact Tester  Used to assess catsuit coating at a very fst deformation ablility to resist cracking or fall out .

  • Hardness tester and Tensional test .

  • Cupping test.

    The coating cup drawing tester Used to assess catsuit slow deformation under coating ability to resist cracking or fall out .

    The cupping test is a test method applied in the metalworking industry and is used to determine the ductility of sheet metals and strips.

    For the performance of cupping tests on sheet metal a spherical drawing punch is pressed

into a clamped metal sheet until a crack appears. The cupping test is used to assess drawing formability.

Our Product Services

l Cut large coils into small coils or Strip .

For steel coils, we can cut one large steel coil into small steel coils for loading at seaport; because for container shipping, each container usually loads weight can not be over 26 tons, but each large coil is usually about 28 tons, so one large coils has to be cut into small coils, and because the forklift usually takes 7-10 tons at seaport, so for easy loading into conatiner, each large steel coil usually is cut into 3 small coils. For bulk vessel shipping, it usually demands coils weight under 18 tons, so most times, also need cut one large coil into 2 small coils.

l  Open flat coils into steel plate.

For final application, need open flat the coils and cut the coils into steel plate, so we open flat the coils and cut the coils to steel plate to the sizes as required. For saving cost for loading by container, load into 20 feet containers, so cut the length under 5800mm, usually as required to cut to length 2440mm and 5800mm, width usually be 1220mm and 1500mm.after cutting the steel coils into steel plate, we can do black paints on the surface of the plate to make the plate to be anti-rust.
