Good dynamic characteristics of truss - earthquake resistance, wind resistance

Sufficient strength - no fracture or plastic deformation; sufficient rigidity - no excessive elastic deformation; sufficient stability - no collapse due to sudden transition of equilibrium form; good dynamic characteristics - shock resistance, wind resistance.

Design requirements for trusses: There must be rods that meet the requirements; there must be good connections, including rivets, pins and welds. These relate to the type of truss, the size and material of the members, but first the static analysis.

1. Seiko welding: large-scale machines, flow operations, technicians for many years, professional welding, quality assurance.

2, paint technology: car quality, professional paint room, Seiko paint technology.

3. Standard processing: large machine positioning, accurate hole position.

4. Leading technology: have its own rental and installation company, first-line research and development, always leading
