corrugated steel pipe
corrugated steel pipe https://www.corrugatedsteelculvert.com/ The project will form a web of twists and turns corrugated web, greatly improve the stability of the steel web, the web thickness is reduced by more than 50%, to achieve light weight and materials. The outcome of the establishment of a complete corrugated web steel design theory. Addresses this new steel web and flange locally stable beam overall stability and local pressure, fatigue, a combination of a series of calculation and design of beams and other theoretical issues, the preparation of the first specialized domestic and foreign design specifications; developed corrugated steel webs proprietary manufacturing equipment. corrugated steel pipe , structural plate, CSP culvert
