Galvanized Steel Strip

Galvanized steel strip is ordinary steel strip pickling, galvanized, packaging and other processes processed, because of good corrosion resistance, so widely used. It is mainly used for making metal articles which are cold processed and no longer galvanized. For example: light steel keel, guardrail peach column, water tank, rolling door, bridge and other metal products.

Advantages of galvanized steel strip  

1, corrosion resistance: galvanized steel belt has good corrosion resistance, neutral salt spray test up to 240 hours.  

2, beautiful appearance: galvanized steel strip appearance is smooth, no zinc nodules and burrs, silver white.  

3, keep the characteristics of steel: galvanized without hydrogen embrittlement, no temperature harm, can ensure the mechanical properties of the material unchanged.  

 

Galvanized steel belt type  

1, hot dip galvanized steel belt.  A sheet of steel is dipped into a molten zinc bath so that it adheres to a sheet of zinc on its surface.  

2, alloyed galvanized steel strip.  This steel plate is also made by hot dip, but it is heated to about 500℃ immediately after the groove, so that it generates an alloy film of zinc and iron.  This galvanized sheet has good bonding and weldability.  

3. Zinc steel plate.  This galvanized steel strip made by electroplating has good machinability.  But the coating is thinner and the corrosion resistance is not as good as hot dip galvanized sheet.  

4, single-sided galvanized and double-sided difference galvanized steel belt.  Single-sided galvanized steel strip, that is, galvanized only on one side of the product.  It has better adaptability than double-sided galvanized sheet in welding, rust prevention and processing.  In order to overcome the shortcomings of single side not coated with zinc, and a thin layer of zinc coated on the other side of the galvanized sheet, that is, double-sided difference galvanized sheet.  

5.  Alloy and composite galvanized steel strip.  It is an alloy made of zinc and other metallic metals such as lead, and even a composite plated steel plate.  This kind of steel plate has both excellent anti-rust properties and good coating properties.

 

Application of galvanized steel strip  

1, general civilian: processing household appliances, such as sinks, etc., can strengthen the door panels, etc., or strengthen kitchen utensils and so on  

2, construction industry: light steel keel, roof, ceiling, walls, water baffle, rain lap, rolling door, warehouse inside and outside board, insulation tube shell, etc  

3, household appliances: refrigerator, washing machine, shower, vacuum cleaner and other household appliances reinforcement protection  

4, automotive industry: large cars, trucks, trailers, luggage cars, refrigerated car parts, garage doors, wipers, mud baffle, fuel tanks, water tanks, etc  

5, industrial industry: as the base material of stamping materials, in bicycles, digital products, armored cables and so on will be used  

6, other aspects: equipment box cover, electrical cabinet, instrument panel, office furniture, etc.
