In the space truss project, each steel structure space truss component we install and use has certain requirements. Generally, the steel structure space truss will put forward special or higher requirements in the following aspects:

Structural parts: material, surface roughness, tolerance, surface treatment, straightness (or radian);

Connection: hole position deviation and bolt grade; Welding method, welding standard and welding materials; Air tightness, requiring nondestructive testing, liquid penetrant testing, etc;

Overall structure: verticality, levelness, etc;

Packaging: packaging materials and methods;

Storage: ambient temperature and humidity;

Transportation: loading and unloading, placing in the vehicle, placing in the container, etc
