Our engineer team for prefab metal buildings( made of steel frame ) :We owns 36 TEKLA professional designers, by applying computer work station. They make the model for steel structure items assembling, define the assembly dimension and inspect the connection status of each joint in three-dimensional way through difference perspectives, which has optimized the design for realizing 100% successful bolt installation, greatly enhancing working efficiency. We owns 15 professional STAAD-Pro designers. As for secondary design and partition treatment of drawings, our design team applies STAAD-Pro together with Ram Connection module to optimize joint design to establish scientific and reasonable assembly design scheme.5. The advantages of prefab metal buildings( made of steel frame ) :1) Economic: quick installed and saving the cost of construction. 2) Reliable quality: mainly produced in the factory and control the quality. 3) Big space: the max span of prefab steel structure can reach 80meters. 4) Anti-seismic: because the weight is light. 5) Flexible: can be dismantled and enlarged. 6) Beautiful appearance: can use different colors. 7) Long lifespan: can be used more than 50 years.6.
