This project involves the steel structure roofing works for the finished petroleum pump shelter and oil metering station pump shelter at the Beihai Finished Petroleum Reserve Base. The structure adopts a portal steel frame design, with both design and construction strictly following national and industry standards. The total span is 18m, length 90m, column spacing 6m, eave height 6m, and seismic fortification intensity of 6 degrees. Considering the influence of near-field earthquakes, the structural seismic grade is set to Level IV.
Structure Type: Portal steel frame
Purlin Material: Cold-formed thin-walled C-section steel
Bracing, tie rods, diagonal rods, sleeves: Galvanized Q235B steel
Roofing Material: 0.8mm sky-blue color steel sheet
Seismic Grade: Level IV
Cutting and bending strictly follow process specifications
Advanced equipment ensures smooth edges and precise bending angles
Avoid stress concentration and unnecessary deformation
