Customer visit HiTo company to consult continuous hot dip galvanizing line

Bangladesh customer ordered a continuous color coating line from HiTo in 2022,and he is satisfied to HiTo's product quality,solution and service.Because of business extand,he came to our company again,visited coils continuous hot dip galvanizing line factory,and discussed solutions with our boss and engineer team. Hope we can cooperate again as soon as possible.




Galvanized steel coils are widely used in many fields due to their excellent corrosion resistance, molding ability and durability.  The following are the classification and specific application scenarios of its main uses:

 1. Building and Structural Engineering
 Roof and Walls .Galvanized steel coil is the base material of color steel plates (pressed plates). It is widely used in the roofs and walls of industrial factories, warehouses, airports, gymnasiums and other buildings, and has the advantages of waterproof, rust prevention and lightweight.
 Steel structure support: used for light steel keels, purlins, trusses and other building skeletons, corrosion-resistant and strong load-bearing capacity.
  Fences and guardrails: Such as highway sound insulation panels, construction site fences, balcony railings, etc., they can maintain stable performance when exposed outdoors for a long time.

 2. Automobile Manufacturing
 Body parts: Galvanized steel coils (especially electro-galvanized steel plates) are often used for parts that require anti-corrosion by doors, chassis, fuel tanks, etc. to extend the service life.
  Exhaust system: High temperature resistant galvanized steel (such as aluminum-zinc) is used for high-temperature components such as exhaust pipes.
 Structural parts: Seat frame, bumper internal support, etc.

3. Home appliances and electronic products
  Case and panel: The housing of refrigerators, washing machines, air conditioners and other household appliances uses galvanized steel coils (mostly cold-rolled substrate + galvanized layer), with a smooth surface and easy to spray.
  Internal structural parts: Such as microwave oven inner liner, oven bracket, etc., it must tolerate moisture or high temperature environments.
4. Agriculture and Animal Husbandry**
  Greenhouse greenhouse skeleton: resistant to moisture and pesticide corrosion.
 Breeding Equipment: Poultry and livestock cages, feed troughs, etc., to adapt to high humidity environments.
 Agricultural Equipment: Harvester and seeder components to reduce rust loss.
5. Transportation
 Ship and Container: The internal structure of the hull and the container shell use galvanized steel coils to resist marine salt spray corrosion.
 Railway facilities: such as train car base plate, track guard plate, etc.
6. Industrial Equipment and Pipelines
 Ventiation pipe: Central air conditioning, factory exhaust system, corrosion-resistant and easy to process.
  Storage tanks and containers: Chemical storage tanks (non-strong acid and strong alkali environment), water tanks, etc.
 Cable tray: The metal bracket for protecting the cables must be protected from rust for a long time.
7. Energy Industry
 Solar Bracket: Support structure of outdoor photovoltaic power generation system to adapt to harsh climates.
  Wind power equipment: Internal structure of the tower, equipment shell, etc.
8. Daily consumer goods
  Furniture: Metal tables and chairs, shelves, filing cabinets, etc., both beautiful and durable.
 Kitchenware: Sinks, chimney pipes, etc. (Food grade plating technology is required).
 




Basics of selection of galvanized steel coils
 Coating type:
   Ordinary hot-dip galvanizing (pure zinc) is suitable for general anti-corrosion needs.  
   Zinc-Aluminum Alloy (such as Galvalume) is used in highly corrosive environments (coastal areas).  
   Zinc-iron alloy (Galvanneal) is suitable for parts that require subsequent spraying.  
 Substrate thickness and strength: Thick board for construction (0.3~3mm), thin board for household appliances (0.15~0.8mm).
