Purlin & Girt

  • Sale03-QD steel building
   

1.Purlin: Its function is to transfer the roof load (wall load) to the beams and columns through the purlins, which are generally C-shaped steel and Z-shaped steel.

2.Girt:
Girt conditions refer to the method in which horizontal girts are attached to the exterior columns of your building.

Flush Girt:

where no space is provided between the columns and exterior panels, offering maximum floor space

Inset Girt:

where minimum air space is provided between the columns and exterior panels

Bypass Girt: 

makes a continuous run around the outside of a building’s columns, providing an air space equal to girt depth between the columns and exterior panels

In steel structure engineering, the application value of purlins is mainly reflected in the following aspects:

  1. Improve structural stability: Purlins, as supporting and connecting components, can significantly improve the overall stability of the steel structure and ensure that the building remains stable in natural disasters such as wind, rain, earthquakes, etc.
  2. Reduce construction costs: Purlins adopt standardized and prefabricated production methods, which can reduce the difficulty and complexity of on-site construction and reduce construction costs.
  3. Improve construction efficiency: Because purlins have good interchangeability and repeatability, installation efficiency can be significantly improved and the construction period shortened during construction.
