Load Capacity Prefabricated Steel Bridge With Simple Structure Modular Design

Modular Steel Bridge Description:

GW D Modular bridge are new kinds ofassembly steel bridges, comprising longitudinal trusses that are formed ofsteel beam chords and pre-fabricated modular steel panel webs, connected end toend with transverse cross girders spanning between them that support a two laneor a single lane, steel deck roadway or concrete roadway.
The surface protection can be paint or hot-dip galvanized.

Modular Steel Bridge Introduction
GW D Modular bridge is a standard bridgeequipment, adopted extensively and the most popular in the world.

Steel modular footbridge is a type ofpedestrian bridge that is constructed using prefabricated steel components. Itis designed to provide a safe and efficient crossing for pedestrians, cyclists,and other non-motorized users over obstacles such as rivers, highways, railways,or other barriers.

The modular construction approach involvesfabricating the bridge components off-site in a controlled environment. Thesecomponents, including steel trusses, decking panels, handrails, and connectionelements, are pre-engineered and manufactured to precise specifications. Thisprefabrication process ensures high quality, reduces construction time, andminimizes disruption to the surrounding environment and traffic flow.



Modular Steel Bridge Advantage

Possessing the features of simple structure.
Convenient transport, speedy erection. The modular nature of these bridgesallows for easy transportation to the construction site. The components can becompactly packaged and transported using standard trucks or trailers.
Easy disassembling.
Heavy loading capacity. Steel is a durable material with excellentstrength-to-weight ratio, making modular steel bridges robust and long-lasting.Steel is also resistant to corrosion, providing longevity and requiring minimalmaintenance.
Great stability and long fatigue life.
Being capable of an alternative span, loading capacity.

Modular Steel Bridge Features
1. High strength and big stiffness, relative to the concrete bridge can bereduced trabecular high and self-respect
2. Due to the steel isotropic, quality of a material is uniform and modulus ofelasticity, that make steel bridge in the working condition and calculationcompared with the assumption
3. GW D Modular bridge generally prefabricated in factory,site assembled by pins and bolts; the construction period is short, processingconvenient and not affected by seasonal effect.
4. GW D Modular bridge is suitable for industrializedmanufacture and very convenient to transport.
5. GW D Modular bridge is easy to repair and replace, longlifetime, material can be recycled.

Modular Steel Bridge Application
Beam bridge, arch bridge, rigid frame bridge, cable-stayed bridge, suspensionbridge. passenger footbridge

Mixture form to erect all kinds of Modular Steel Bridge
Temporary Bridges, Emergency Bridges and Fixed Bridges.

Using the bridge equipment, the suspensionbridges of varied span can be erected.
The bridge has the advantages of few components, light weight and low cost.
Modular steel bridge is similar to the panel bailey bridge from theirappearance. The difference is its increased truss panel height and truss panelsection is larger to afford more loading. Pre-arch method is used toadditionally cut down mid-span and vertical deflection to a larger degree.
The components are connected by connecting plates and fixed with high-strengthbolts. Modualr steel bridges has all the advantages of Bailey bridge, and witha larger span and stronger load-bearing capacity.
