Rectangular GI Duct
Hot-dip galvanized rectangular ductwork, accurately formed for efficient commercial and industrial air distribution.
Lightweight, corrosion-resistant aluminium ducting for cleanrooms, wet areas and weight-sensitive installations.
Aluminium ductwork reduces installed weight while offering strong resistance to atmospheric corrosion. Its formability suits custom duct sections, external cladding and specialist ventilation. Indigo Sky coordinates alloy, temper, joint method and support spacing to prevent oil-canning and galvanic incompatibility with adjacent materials.
Typical construction information for early coordination. Final values are governed by the selected model, approved material and project design.
| Material | Aluminium sheet, alloy/temper to specification |
|---|---|
| Thickness | Commonly 0.7u20131.5 mm, size dependent |
| Forms | Rectangular, round, fittings and external cladding |
| Jointing | Lock-formed, riveted or welded as required |
| Finish | Mill, stucco embossed or specified finish |
| Isolation | Compatible separation from dissimilar metals |
Alloy, thickness, joint design and supports are engineered for the actual duct size and environment; dissimilar-metal contact must be isolated.
