Q1: What is the maximum span of steel grid structure?
A1: Regular span covers 50m-80m, and customized design can break 100m.
Q2: What is the main difference between grid and truss structure?
A2: Space grid bears force in three-dimensional direction, more suitable for ultra-large span projects; steel truss mainly bears planar force.
Q3: How is its wind and earthquake resistance performance?
A3: It reaches 8-degree seismic resistance standard, and can resist grade 12 typhoon in coastal areas.
Q4: What anti-corrosion method is used for coal shed grid structure?
A4: Heavy-duty anti-corrosion paint and hot-dip galvanizing treatment are adopted to adapt to dusty and corrosive working environment.
Q5: What are common matching roof panels?
A5: Color steel sandwich panel, aluminum magnesium manganese plate and daylighting panel with daylighting belt are all optional.
