G550 Structural Grade Galvanized Slitting Steel Coils Zero Spangle Galvanised Steel Strips G40=Z120 for roller doors

Classification of galvanised steel 

Hot rolled galvanised steel sheet: hot rolled steel sheet with pickled substrate.

Cold rolled galvanised steel sheet: the substrate is cold rolled or hardened steel sheet.
 

Galvanised steel coil applications:

Galvanised steel coils are used in a wide range of applications and have the advantage of a long corrosion protection period. It is mainly used as a building and substrate for household appliances, office panels, roof panels, automotive panels, and pre-painted steel coils.

Automotive Steel Sheet

　　To use automotive steel plates must first be stamped and formed, where the plates are stamped into parts of the desired shape and size.

　　Spot welding, as an important welding method for joining thin plates, has a wide range of applications in manufacturing, especially in the automotive industry.

Galvanised Roof Sheet

　　The performance requirements for galvanised roof sheets mainly include the mechanical properties of the material (tensile strength, yield strength, elongation), coating properties (coating type, coating thickness and coating adhesion).

Household Office Galvanised Sheet

　　Including air conditioners, washing machines, refrigerators, photocopiers, etc. Household galvanised sheet is mainly used for general forming applications and stamping.

　　PrePainted Steel Base Metal Substrates

　　Another use for galvanised steel coils is as a substrate for pre-painted steel coils. Pre-painted steel coils are more durable than galvanised coils as they have a polyethylene coating.

DECHO building colour steel plate can meet the need to use colour steel plate as raw material for building.

DECHO BUILDING MATERIALS colour steel plate is mainly processed into, for example, colour steel corrugated board or colour steel composite sandwich board after our colour steel plate is widely used in the construction of airports, freezers, steel plants, warehouses, and other industrial buildings and commercial buildings, such as the roof of the colour steel tiles, colour steel plate sandwich walls and doors.

Reasons for choosing DECHO BUILDING MATERIALS:

1,Provide extremely rich colour choices

2,The paint surface is long-lasting and bright

3,Surface coating will not fall off after stamping and has good hardness with strong ductility and is not easy to scratch.

4, with excellent weather resistance, corrosion resistance, is to ensure the durability of the premise of the building

5,DECHO BUILDING MATERIALS for the manufacturer direct sales

6,The colour is customized by customers;

7,Thickness and width have a variety of options;

8,We provide whole rolls and cut boards for sale;
