Carbon Steel Ventilation Assembly With Hood Air Duct and Welded Flanges

We supply a controlled specification sheet so key datums and flange interfaces stay stable across your builds. For each hood air duct order, we lock material family, surface finish, and tolerance specificationss as measurable controls. If you require traceability, we can add a batch code on the builds and include a material certificate in the shipment. The lead time and pricing are set by duct size envelope, wall thickness, and overall weld length. Our facility builds hood air duct to hold critical features without extra rework. Our IATF 16949 and ISO 9001 factory plant in Wuxi runs welded and formed metal assemblies for vehicle applications.
