Project Overview
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 and Materials
-
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
Roofing System Installation Process
During the installation of the steel roofing system, the construction team used tight panel-to-panel overlaps to ensure waterproofing and structural stability. Along the centerline of each reinforcement rib, roofing sheets were precisely laid and fixed to the purlins below using self-tapping screws with waterproof caps, enhancing overall roof strength and ensuring long-term durability under harsh weather conditions.
Quality and Process Control
To ensure the quality and performance of the corrugated color steel sheets, Sanjian Meichen implemented strict quality standards for cutting, bending, and welding:
-
Cutting and bending strictly follow process specifications
-
Advanced equipment ensures smooth edges and precise bending angles
-
Avoid stress concentration and unnecessary deformation
-
Ensure flat, aesthetically pleasing, and well-sealed roof installation
Project Value
This steel structure roofing project has significantly improved the protection performance and service life of the pump shelter and metering station, providing strong assurance for the safe operation of the petroleum reserve base. The durable roof structure can effectively withstand varying climate conditions and long-term industrial operation demands.
