Tube 300Ø 900mm 24g Galvanised

Round Galvanized Sheet Metal Duct – 300mm Ø x 900mm

The Round Galvanized Sheet Metal Duct is a strong and efficient solution for distributing air in HVAC systems. Made from high-quality 24 gauge galvanized steel, it provides durability, corrosion resistance, and long-term performance.

Each duct section is swaged (big end/small end) for easy, secure connection to consecutive duct pieces, sheet metal fittings, or flexible duct, ensuring a tight and reliable joint.

Features

• Diameter: 300mm, Length: 900mm

• Round profile for efficient airflow distribution

• Material: 24 gauge galvanized steel for strength and corrosion resistance

• Swaged ends (big end/small end) for simple, secure joining

• Suitable for commercial, industrial, and residential HVAC systems
