ASTM A709-50W is a standard specification for structural steel primarily in the fabrication of steel bridges. ASTM A709-50W covers high strength, low allow steel structural shapes, plates and bars. The atmospheric corrosion resistance of this steel in most environments is substantially better than carbon steel with or without copper addition. CSA 350W CLASS C - Acier AltitubeCSA G40.21 50W / 350W (Canadian Standards Association) is the Canadian specification for Hollow structural section ( H.S.S). These tubes can be manufactured with different shapes:round, square, and rectangular H.S.S tubes in hot rolled and cold formed steel.
CSA grade G40.21 50W / 350W is available with Charpy V-notch impact test. This test measures the energy absorbed by the steel at the fracturing point. The Charpy V-notch impact test is made at differents temperatures. The product nomenclature indicates the letter T for Toughness and its category (1 to 5 ). CSA G40.21 50A / 350A Structural, Carbon & HSLA Steel An atmospheric corrosion-resistant weldable notch-tough steel plate grade specified within G40.21 of the Canadian Standards Association (CSA). This plate is utilized primarily in structural applications such as bridges and buildings. When properly exposed to the atmosphere, this steel plate can be utilized in its bare condition (unpainted).

quality steel / structural quality steel. INTENDED USE Welded, riveted, or bolted construction of bridges and buildings, and for general structural purposes. General specifications for plates, shapes, hollow sections, sheet, sheet piling cold-formed channels and bars used in construction. SPECIFICATIONS ROUND STRUCTURAL TUBING STRENGTH LEVELS Grade C 50W Section Eight Structural SteelThe preferred structural steel is unpainted weathering steel. Two grades are available; ASTM A709 Grade 50W and Grade 70 HPS - 70W. This steel eliminates the need for painting because the steel weathers to form a protective patina, or thin layer of protective oxide coating, that prevents the steel from further rusting.
