Multi Span Steel Pedestrian Bridge Single Lane Steel Box Girder Bridge

Footbridges or Pedestrian Bridges are needed where a separate pathway has to be provided for people to cross traffic flows or some physical obstacle, such as a river. The loads they carry are, in relation to highway or railway bridges, quite modest, and in most circumstances a fairly light structure is required. They are, however, frequently required to give a long clear span, and stiffness then becomes an important consideration. The bridges are often very clearly on view to the public and therefore the appearance merits careful attention.

Steel offers economic and attractive forms of construction which suit all the requirements demanded of a footbridge. Steel box girders are very commonly used for footbridges over 30m span. Box girder footbridges use an all-steel configuration as the entire cross section including the parapets can be fabricated. The top flange of steel box girder acts as the floor of the bridge, and there are usually short cantilevers either side of the box. This form has the benefits of good torsional stiffness, which can simplify support arrangements and clean surfaces which minimize maintenance.

Advantages of box girders

• Reduce the requirement for support points
• Have high strength and torsional stiffness that give greater and better suitability for horizontally curved bridges
• Ensure enhanced durability
• Require minimum maintenance of simple protective coatings as these have less exposed surface and only a few edges

Specification

Application

Steel box girder bridges are commonly used for highway flyovers and for modern elevated structures of light rail transport. Although normally the steel box girder bridge is a form of beam bridge, box girders may also be used on cable-stayed bridges and other forms.

Construction
For steel box girders, the girders are normally fabricated off site and lifted into place by crane, with sections connected by bolting or welding. If a composite concrete bridge deck is used, it is often cast in-place using temporary falsework supported by the steel girder.

Either form of bridge may also be installed using the technique of incremental launching. Under this method, gantry cranes are often used to place new segments onto the completed portions of the bridge until the bridge superstructure is completed.

Our company

Our highly trained team of engineers and craftmen focus on your steel bridge project's details and 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.

Hangzhou USEU Metal Manufacturing Company (shortly called as USEU) lies in Yuancun Village, Xindeng Town, Fuyang District, Hangzhou city, Zhejiang Province. It covers an area of 80,000 square meters. The traffic is very convenient. It is 50 kilometers away from Hangzhou Airport and five kilometers from Fuyang Motorway Entrance& Exit. By Train it is only 1 hour away from Shanghai, the largest city of China.

Our registered capital is RMB 10 million Yuan, and now USEU have over 100 million Yuan in total assets. The annual production capacity can reach more than 90,000MT. USEU have over 200 staff and workers overall and over 50 professional and technical personnel. We invite senior engineers and specialists of China Steel Structure Association Councilor and Scientific department of the General Equipment as our consultants, and hold technical communication meetings time to time.

Most importantly, not like other companies, nearly all machining parts and mechanical accessories are manufactured in our own shop as we have professional machinery line and skilled workers inside. In this way, the quality, cost and delivery time can be ensured which eliminates other exterior factors’ influence.

We have passed the ISO 9001:2000 International Quality Management System Authentication, America AWS D1.1 Qualification, EN1090-2 Certification and ISO3834-2 Europe standard welding system certification. The company is recommended as the Demonstration of Quality Management by China Quality Observation Station; Safe Production Advanced Unit by the city government, Industrial and Commercial Relief Enterprise by the city Industrial and Commercial Bureau in 2016, Rank A enterprise of Labor Protection by the city Labor Bureau in 2016, A business tax credit of Hangzhou city. At the same time we declare the patent of the technology production and the practical production of Equipped Road Steel Bridge to National Knowledge Property Right Bureau.

Our main production is various structural steelworks fabrication and steel-based bridges design/fabrication, in which the modular Bailey type Steel Bridge is the most popularly used. Meanwhile we are developing new models of various prefab steel bridges with state-of-the-art technology absorbtion and development, including but not limited in the truss bridge, box girders, arc shaped bridge, overpass etc.

We adopt the Road Bridge Construction Technical Rules (JTL041200) by the Ministry of Communications to process, and make the steel bridge, which is simply-structured, conveniently-transported, strongly-suited, well-exchanged, rapid erection, and huge load. It is widely used in national defense equipment, flood fighting, transportation, irrigation works, railway and so on. We also specialize in producing the derivative product of steel Bailey bridge, such as panel pin, nonstandard transom, bridge deck, female end post, male end post, bridge seat, baseplate, reinforced chord, clip and so on. All the machining accessories of Bailey type bridge are done by ourselves, which can control the quality, cost and delivery time.

Our company undertook the construction of national key projects form China Railway Bridge Bureau, China Tunnel Traffic and China Railway Shanghai Bureau. And the qualities are quite good. Because of the good quality, our productions are exported widely wordwidely like North America, Europe, South America, Middle East, Oceania, Africa and Asia countries such as Chile, Costa Rica, Ecuador, Canana, Australia, New Zealand, Laos, Angola, Saudi Arabia, Poland, Romania, Kenya, Nigeria, Bangladesh and Myanmar etc. So we are widely received and accepted by the international markets.

To satisfy the demands of the market, we set up a renting company in 2016, which rents Bailey Piece and a complete set of steel bridge as well. It also forms a professional bridge erecting group. Nowadays, Jiangsu Jiuzhou Bridge has formed a supermarket of steel bridge which combines design, making, fitting, renting, transportation to become a first rate enterprise.

The company will takes full advantages of flexible mechanism and strong technical force, be market-oriented, adherence to the “customer first, quality first and integrity management” as the quality policy and “quality and creditability” as the enterprise tenet to ensure that customer requirements are satisfied and translate them into the demands for products and service. It provides the high-quality products and service for customers and try its best to create band and credibility, enrich the outstanding professional personnel, creates benefits with scientific management and advanced technology to create a first-rate steel structure enterprise.

Now as the biggest shareholder of USEU, FAMOUS Steel Engineering Company is awarded to be the only export project agent for all kinds of overseas market operation.

Lastly we would like to emphasize that we are able to do various standards structural steel fabrication ranging from normal China standard, to Europe standard, America standard, British BS Standard, Australia New Zealand AS/NZS standard and steel based bridge s design & construction upon different clients' requirements.

USEU is willing to create a better tomorrow with you! Warmly welcome various clinets either from Domestic or International market to visit us!
