SSAB Weathering and COR-TEN - SSAB high-strength steel

COR-TEN WEATHERING STEEL FOR PROTECTION OF STRUCTURES AND BRIDGESis high strength,low alloy weldable structural steel with exceptional weathering resistance.The chemical composition of the steel allows for the creation of a layer of rust that coats a building without altering the mechanical characteristics of the steel.This rust layer,not only protects architectural steel products against the elements,but also delivers a unique finish that Research Report An Assessment Of Weathering SteelThe use of weathering steel in highway bridges has historically been a source of controversy,despite the potential for significant increases in cost-effectiveness.The first weathering steel bridges in America were constructed in the mid-1960s,with a significant percentage of the early weathering steel bridges constructed in Michigan.Related searches for WEATHERING STEEL FOR PROTECTIOwhat is weathering steelweathering steel costweathering steel maintenanceself weathering steelweathering steel llcweathering steel platewelding weathering steelpainting weathering steelSome results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextCorrosion Processes on Weathering Steel BridgesThe rated bridge structures are located on the same roadway.The supporting structures of both bridges are made of S355J2W weathering steel.The distance between the centers of the bridges is approximately 200 m (see Figure 3).The bridge structures are similar in design girder bridges
