Steel structures, such as those used in buildings, bridges, and industrial facilities, undergo a series of processing steps to transform raw steel materials into the final assembled components.

The assembled steel structure undergoes surface preparation, such as cleaning, degreasing, and shot blasting, to remove any contaminants or rust.

Protective coatings, such as paints, galvanization, or specialized fireproof coatings, may be applied to the steel surface to enhance corrosion resistance, fire protection, and aesthetic appeal.

The steel components are cut, shaped, and prepared for assembly using processes like sawing, drilling, punching, and welding.

Specialized machinery and equipment, such as CNC (Computer Numerical Control) machines, are often used to ensure precision and efficiency.

• Large span capability
• Fast construction speed
• Energy efficient
• Aesthetically pleasing appearance
• Excellent seismic performance

The primary load-bearing structure that bears vertical loads. Composed of upper chord, lower chord and belly rod (divided into diagonal bar and vertical bar). Nodes are divided into large nodes and small nodes, with pitch referring to the distance between nodes.

Classification: Longitudinal connection and horizontal connection.

Function: Connects the main truss, creating a stable space structure capable of withstanding various lateral loads.

The longitudinal connection system (upper and lower horizontal) withstands transverse horizontal loads, wind, rocking forces and centrifugal forces while supporting chord elements.

The transverse connection (bridge frame and crosslink) increases torsional stiffness and helps balance forces between main stringers.

Composed of longitudinal beams, beams and their connections. Load transfer path: deck → longitudinal beams → beams → main truss.

The surface for vehicles and pedestrians, with forms similar to steel beam bridges and combined beam bridges.

• Compliance with building codes and safety standards
• Minimizing waste and optimizing resource utilization
• Efficient logistics and supply chain management

Highway and Road Bridges: Steel truss bridges are frequently used in the construction of highway and road bridges. They are suitable for a wide range of span lengths, from short to long, making them versatile for accommodating different road widths and crossing various terrains.
