Galvanized Steel Coils for HVAC
One of the main industries we serve is the HVAC system, producing galvanized steel coils of different grades/standards and with various zinc coatings, as well as galvanized steel sheets of various specifications.
- Thickness: 0.4mm – 2.0mm
- Standard Width: 600mm – 1250mm
- Material：DX51D+Z / SGCC+Z、S220GD+Z、S250GD+Z、S280GD+Z
Ensure product quality and transportation
Galvanized steel coils, with their corrosion resistance, strength, and ease of processing, are used in almost every aspect of HVAC systems. We not only produce galvanized steel coils, but also have cutting equipment to precisely cut them into galvanized steel sheets.

Applications of Galvanized Steel Coil in HVAC Systems
- Ventilation Duct Systems: This is the primary application scenario for galvanized steel coils, including supply air ducts, return air ducts, fresh air ducts, exhaust air ducts/smoke exhaust ducts, and ductwork fittings such as elbows, tees, and reducers.
- Structural Support Components: Components such as duct hangers, brackets, and fixing clamps, as well as the base frame of air conditioning units, require a certain degree of rigidity and corrosion resistance, which galvanized steel coils can meet.
- Air Conditioning Unit and Equipment Housings: The housings of modular air conditioning units/fresh air handling units, fan boxes/fan coil units, and fan coil units/indoor units are often made of galvanized steel coils, balancing strength and corrosion resistance.
