Portable Prefabricated Galvanized Steel Bridge , Long-Term Long Span Bridge Corrosion Protection

64m Long Span Portable Prefabricated Galvanized Steel Bridge Long-term Corrosion Protection

Description

Galvanized steel bridges provide a wide range of advantages when compared to competitors, ranging from aesthetic options, extended time to first maintenance, and even superior seismic stability. Galvanized steel is a lighter-weight construction material than concrete, which makes it ideal for long-spanning bridges. Additionally, the production process has significantly improved over time.

Specification

Application

Generally used for urban bridges or highway viaducts and overpasses with small spans
Reinforced concrete: medium and small span
Prestressed reinforced concrete: large span
Straight leg frame (door type) and slant leg frame: medium and small span
T-shaped rigid frame, continuous rigid frame: large span

Features
Because of improvements in production techniques, the cost of using galvanized steel for bridge construction has also decreased over time. The amount of energy required to produce one ton of steel, for instance, has decreased by 34% since 1972.The galvanizing process additionally helps prevent corrosion in a much more affordable way than stainless steel, which means that the bridge will last longer with less maintenance.

Safety
Steel construction is more flexible than other building tools, meaning that a bridge is more resistant to seismic activity. Bridges made of steel are also easier to inspect for safety than concrete. And while galvanized steel has always been extraordinarily resilient against weather conditions, metals are now 30% stronger and more dent-resistant than they were even 10 years ago.

Competitive Advantage

Longer main spans are achievable than with any other type of bridge
Less material may be required than other bridge types, even at spans they can achieve, leading to a reduced construction cost
Except for installation of the initial temporary cables, little or no access from below is required during construction, for example allowing a waterway to remain open while the bridge is built above
May be better able to withstand earthquake movements than heavier and more rigid bridges
Bridge decks can have deck sections replaced in order to widen traffic lanes for larger vehicles or add additions width for separated cycling/pedestrian paths.

Our company

Our experienced team is focused on your steel bridge project's success, from start to finish. Our proven ability to identify and overcome design inconsistencies, potential problems with erection, and shipping obstacles results in the fabrication of structural steel that is right the first time, helping you avoid costly construction delays.

Proper project coordination and efficient delivery of the structural steel to your bridge project is a key factor in its ultimate success. This is what gives us the leading edge.

From material purchase and tracing, planning compilation, drawing detailing, production arrangement, quality inspection, to on-going painting, packing and delivering, we have separated department to strictly control process, quality and traceability, so that the perfect Bailey/Belay/Baley Bridge can be made. 

Finally we would like to emphasize that not like other companies, nearly all machining parts and mechanical accessories are manufactured in our own shop as we have so many wonderful machines and workers inside. In this way, the quality, cost and delivery time can be ensured which eliminates other exterior factors’ influence.
