Weather steel plate, with alloy elements, such as Cu, Cr, Ni added, the anti-corrison structural steel acquires a corrosion resistance ability and extends the service life, in the development and producing of anti-corrosion structural steel. Our weather steel plates suitable for welding and bending, anti-corrosion structural steel is easy to use, and widely used in the field of marine container and railway Construction Health and Safety Manual:IronworkersThe fumes from welding and cutting are the greatest health hazards for ironworkers. Exposure to welding by-products such as fumes, radiation, noise, or vibration is covered in the chapter on Occupational Health. The risk to your health is worse when there is a lead-based paint on the metal being cut or welded. The following sections deal with

How to Weld Weathering (CORTEN) Steel WELDING

Structural Welding Code. It is a group II steel which means prequalified welding procedures may be used. The filler metal to be used depends on the following:Specific code requirements; Required strength; Color matching requirements; As mentioned above, AWS D1.1 covers A588 steels. Because weathering steels are largely used in bridges, AWS D1.5 (Bridge Code) also imposes certain requirements and limitations governing the welding Paint coatings - SteelConstructionfoPaint is the most commonly used material to protect steel. Paint systems for steel structures have developed over the years to comply with industrial environmental legislation and in response to demands from bridge and building owners for improved durability performance. Previous five and six coat systems have been replaced by typically three
