Henan Total Construction Engineering Co. , Ltd. (Dowdar) focuses on prefabricated steel structures and prefabricated construction systems for projects such as production halls, logistics buildings, workshops, farm structures and commercial facilities.

Its role is primarily as a supplier of prefabricated structural packages rather than a finished-home retailer. Buyers can assess the company for fabricated frames and related envelope components, while aligning design loads, corrosion protection, insulation, openings, delivery terms and on-site assembly with the requirements of the destination project.
