Ventilation Ducts
Galvanized coil for rectangular and spiral ventilation ducts and fittings.
In ventilation and air-conditioning (HVAC) systems, air is carried through ducts made of galvanized steel. Ducts usually run through ceiling voids and shafts and may be exposed to humid air, so the protection of the zinc coating matters.
GI galvanized coil is suitable for folding rectangular ducts, winding spiral ducts and producing fittings such as bends, reducers and grilles. Larger ducts use thicker sheet.

GI Galvanized Steel Coil
Hot-dip zinc coated coil for profile and duct manufacturing.
Where is GI galvanized coil used?
GI is steel coil zinc coated by hot-dip galvanizing. It is the raw material for drywall profiles, ventilation ducts and trapezoidal sheets. The common grade is EN 10346 DX51D+Z.
Why choose Magnelis over standard galvanized steel?
Magnelis' key advantage is its stronger self-protection against corrosion at cut, punched or exposed edges. That makes it the better choice for solar, agricultural and outdoor profiles that are cut and punched.
