Girder Steel I Beam Bridge Pedestrian Bridge Over Road Railway River Skewed Curved

A girder bridge with a truss as the main load-bearing structure, referred to as a truss bridge, is a bridge whose main girder is mainly subjected to bending as the main load-bearing member. The truss bridge has a simple appearance and is convenient to manufacture, install and maintain, so it is widely used in medium and small span bridges.

The structural truss bridge is generally composed of two main trusses and longitudinal and transverse connections to form a spatial structure.

The members of the steel truss bridge are composed of section steel and steel plate. In the early days, riveted rods mostly used strips and strips, but now they are mainly shaped steel and whole plates. Most of the welded rods are made of steel plates. Some of the small-span truss beams use section steel (flat steel, angle steel) as members. The intersection points of truss members are called nodes. The intersecting members are connected by gusset plates to form a truss. The connection methods include riveting, bolting or high-strength bolting, welding, etc. In the early days, there were pivot connections, which are no longer used. Some military structures also use pin connections. In theory, all-welded truss bridges are the most economical, but trusses with larger spans cannot be welded into a whole in the factory, and the construction site conditions are difficult to ensure the welding quality, so most of the rods and other components are welded in the factory, and the Connect with high-strength bolts to build a bolted beam bridge. The connection of ordinary bolts is mostly used for temporary truss bridges.

All of our  Bridges can be tailored to meet customer-specific requirements. In addition to any special load requirements, we are able to accommodate site-specific topography, extremes of high temperature, high wind loads and seismic requirements.
