Weathering structural steel has been used for various outdoor load-carrying structures (even without anti-corrosion surface protection) in the world as well as in the Czech Republic for about 45 years [1, 2, 3]. Load-carrying structures are designed for service life of as many as 100 years and the weathering steel can be used as a standard structural material without any corrosion protection.FABRICATED BRIDGE PRODUCTS - L.B.

Background Since the early 1960s, uncoated weathering steel (UWS) has been shown to be a cost-effective corrosion protection solution for steel bridges in the United States, and internationally. UWS eliminates the need for paintingResearch on corrosion and fatigue performance of performance of uncoated weathering steel highway bridges1. Introduction. Weathering steel (WS) is a type of low-alloy steel that has superior corrosion resistance relative to conventional carbon steel. The application of WS in bridge structures can be traced back to half a century ago, in which WS was used for highway bridges for the first time in 1964 .Since then, WS has gained considerable developments in bridge construction, owing to its good performance of uncoated weathering steel highway bridges

Steel as a Material for Bridges IspatGuru

Dec 03, 2015Steel has long been recognized as the economic option for a range of bridges. It dominates the bridge constructions for long span bridges, railway bridges, footbridges, and medium span highway bridges. It is now increasingly the choice for shorter span highway structures as well. Early bridges were made of stone, wood and concrete.Structures, 2014. Volume 1.

The Role of the Direct Current Electric Field in Enhancing performance of uncoated weathering steel highway bridges

May 17, 2021Weathering steel (WS) is widely applied to construction and building (highway bridges, buildings, art sculpture), due to its excellent mechanical properties, corrosion resistance, and esthetic features (Ref 1,2,3).The WS is mainly characterized by an excellent corrosion resistance for atmospheric corrosion, which heavily depends on a compact and uniform rust layer.Types of Steel Bridges - American Iron and Steel InstituteThe first bridge using this material was built over the New Jersey Turnpike in 1964. The use of uncoated weathering steel typically provides initial cost savings of 10 percent or more, and life cycle cost savings of at least 30 percent over the life of the structure. Initial cost savings are realized because weathering steels do not need to be painted.Weathering Grade Steel Tube Manufacturer in North AmericaGeneral applications bridges, utility/light poles. Normally in stock 3/16 1/4 3/8 (Custom sizes inquire on lead time) Uncoated weathering steel typically provides initial cost savings of 10-15% by avoiding the expense of painting, and savings of at least 30% over the life of the structure.

High-performance weathering steel Concrete bridges are more commonly used for the smaller spans, since rust in steel members increases corrosion and maintenance costs. Use of weathering steel minimizes painting cost.

Growing use in bridges has resulted in over 40% of all struc-tural steel used in bridges to be weathering steel. However, there are conditions where bare unpainted weathering steel may have problems developing a protective oxide patina. Examples of these conditions are:Weathering steel - SteelConstructionfoWeathering Steel Bridges are suitable for use in most locations. However, as with other forms of construction, there are certain environments that can lead to durability problems. The performance of weathering steel in extreme environments will not be satisfactory, and its use should be avoided in such situations. [ top] Marine environments
