China Baowu Steel Group Corporation Limited (abbreviated as China Baowu) was formed through the merger of the former Baosteel Group Corporation and Wuhan Iron and Steel (Group) Corporation. A project in Jiangsu, Baosteel, utilized louvers for factory ventilation and part of the roof ceiling. The requirements for the louvers were high resistance to both extreme temperatures and humidity, corrosion resistance, and high wind resistance levels (typhoons, for personnel to walk during maintenance), as well as a long service life, with the ability for personnel to walk on the roof louvers. Our fiberglass louvers stood out and were successfully selected.
