Galvanised 45-Degree Spiral Duct Elbow (250mm – 630mm)
Galvanised 45-Degree Round Duct Elbow – Spiral Duct Bend
A galvanised steel 45° bend for round spiral ductwork, used for gentle changes of direction and for stepping a duct run around beams, pipes and other obstacles. Its segmented construction gives a smooth air transition with low resistance, and the corrosion-resistant galvanised finish suits commercial kitchen extraction and ventilation systems.

When to Use a 45° Bend
Use two 45° bends to offset a duct run sideways or around an obstacle, or wherever space allows a gentler turn than a 90° bend – it keeps airflow smoother and reduces pressure loss.
