Philippine Oval Steel Truss Stadium Bleachers Canopy

This project is pipe truss oval bleachers in Semirara, Philippines with area 2042㎡，width 19.633m, length 104m.

This truss structure includes 21 primary trusses. Secondary truss, steel tie bar, column bracing, horizontal bracing are used to connect the support and primary truss,column top below the truss. The roof purlin is cold pressing rectangular steel tube, the roof cladding is HYK anti-corrosion sheet.

The design use life for this pipe truss structure is 50 years, roofing cladding system use life is no less than 15years. As this project is located near the sea, the wind force is more heavy, the corrosion of sea water is bigger, so this project need to be maintained at certain time（for example: pipes made up by anti-rust paint , repairing destroyed roof panel on time, etc …）
