We offer rectangular ventilation ducts and related duct structures made of galvanized steel, mild steel, aluminum and stainless steel. Other specialty materials and surfaces, comprehensive fittings and additional components are also available. Rectangular ducts are available in almost any size and shape. Rectangular ducting is available in low and medium-pressure versions and the version for smoke extraction systems. Ductwork is manufactured to order at the JHB factory. Usually we will quote you a price based on the drawings you provide or we will help you with any plans or drawings you may need. If you would like a quote for piping production and installation, please send us the required Ductwork drawings by email or paper. If drawings are not available, please contact our team to discuss your project so we can plan and deliver the drawings. Rectangular ductwork differs from round spiral ducting and fittings in that it’s generally not bought ‘off-the-shelf’. If you’re new to rectangular ductwork or don’t have much experience with rectangular ductwork, we’ll provide guidance on how to connect the various parts.
