Building Steel structure Steel structure grid

There are certain requirements for each steel structure grid used in grid engineering. Usually, steel structure grids have special or higher requirements in the following aspects. Haiyao Xiaobian tells you:

Bonding parts: material, surface roughness, error, surface treatment, straightness (or radian);

Joints: hole position deviation, bolt grade; welding method, welding specification, welding material; air tightness, non-destructive testing, liquid penetration test, etc. are required;

Overall structure: vertical, horizontal, etc.;

Packaging: packaging materials, methods;

Warehouse: ambient temperature, humidity;

Transportation: loading and unloading, placing in the car, placing in the container, etc.
