Industrial Steel Structure Buildings for Warehouse, Workshop and Factory Construction
Steel Truss Frame Structure for Modular Building The steel truss frame is a kind of spatial structure, in the construction of building, the steel components are combined in different ways to constituted the rigid frame. Triangular shape delivers more strength and stability with less material and is more ideal for long span and open room.
Outstanding Features
High Strength-to-Weight Ratio -- Triangular truss geometry allows for strong load carrying capacity with less steel.
Wide Clear Span - It has wide maximum depth. No more internal columns needed.
Multi-purpose design – Suitable for warehouses, workshops, manufacturing plants and auditoriums & sports halls
Prefabrication & Rapid Assembly - Steel components are pre-cut and molded off-site and quickly bolted together on-site.
Longevity — A steel building can last for many decades With proper application of corrosion protection (galvanizing, painting, or coating).
Parts
Top Chord: Upper horizontal or sloped member of the truss
Bottom Chord: Bottom horizontal member in tension
Web Members: Diagonal and vertical elements that compose the triangular unit
Connections: Bolted or welded seams that joins the members
Bracing (Optional): Extra lateral stability for large spans
