90-Degree Rectangular Duct Elbow – Galvanised Steel, Made to DW144
Our 90-degree rectangular duct elbow (also called a square duct bend) turns rectangular or square ductwork through a right angle while keeping airflow smooth and pressure loss low. It is fabricated in our Birmingham workshop from galvanised steel, in accordance with DW144 – the UK specification for sheet metal ductwork – so it fits straight into professional commercial kitchen and industrial extraction systems.
