1、 Core advantages of Steel Structure truss

Ultra large span and lightweight design

The span of a single-layer grid structure can reach 60m, and the span of a double-layer grid structure can reach 150m, with a self weight of only 1/5-1/10 of that of a concrete structure;

Typical steel usage: 30-50kg/m ² (depending on span and load), reducing foundation costs by more than 30%.

Rapid assembly construction

The prefabrication rate in the factory is ≥ 98%, and on-site bolt connection or welding can shorten the construction period by 70% (such as completing the 5000m ² venue grid in 30 days);

Maximum lifting unit: bolted ball node grid unit (20m × 20m, weight ≤ 15 tons).

Flexible adaptation to complex shapes

Support grid design for flat, curved, and irregular spaces, which can match spherical, dome, and wave shaped building forms;

Node degrees of freedom: Bolt ball nodes can adjust ± 15 ° angle deviation to adapt to irregular grids.

Whole life cycle economy

Low maintenance cost: hot-dip galvanized anti-corrosion (50 years without major repairs);

The recyclability rate is ≥ 95%, which meets the LEED/green building certification requirements.
