Erection

Erection of pre-engineered buildings and steel structure is the last step in our building process that all the components from the previous steps come together.

General Rules

  • Build column combing with purlins (if any), brace column together. Then, continue building rafters after adjusting column.
  • Install the inside truss frames, and then proceed to erect the outside ones (according to the movement of truck crane – see the enclosed construction drawing)
  • Begin erecting from the braced bay.
  • Settle two construction frames at the braced position before placing new frame. This process is translated for the next frame.
  • Have to have temporary brace during the erection process. Use purlins with the bracing cable to locate, and link all the rafter frames.
  • Erect steel panel after adjusting rafter frame and straight purlin, clean up, and paint all scratches on the rafter and purlin.
  • Use chalks or stretch attached wires to locate or mark axis positions in order to balance the steel panel when to complete the covering.
  • Set foot on the bottom waves when walking on the roof. Steel panel may be crashed if stepping on the high waves, which can cause deformation or leaking.
  • Do not walk on bright panels.
