astm a588 s355j2wp weather resistant plate

ASTM A588 is a high strength low-alloy structural steel specification with improved atmospheric corrosion resistance for structural steel shapes such as angles, channel and beams, as well as steel plate and bars. The A588 specification is intended primarily for use in welded bridges and other structures where savings in weight or added durability is important along with the longer life cycle due to its corrosion resistant properties.

S355J2WP (EN 10025-5) is a structural steel often used for outdoor structures that require enhanced atmospheric corrosion resistance. It is normally used for bridges, pylons, transmission towers and structural parts that are subjected to environmental conditions, such as rain, snow or smog. It has improved corrosion resistance compared to regular carbon steel, due to the added element of copper in its chemical composition.

S355J2WP can be welded using common welding methods. The steel is self-protecting – the rust layer that forms on the surface is formed by the atmospheric corrosion resistance properties found in the steel; there is no need for additional coatings. The metal supplied by suppliers is pre-treated and cut in different forms.

ASTM A588 is a material grade specification for low and intermediate tensile strength carbon steel plates in the USA. The specifications ASTM A 588 covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction with atmospheric corrosion resistance. The atmospheric corrosion resistance of this steel in most environments may be enhanced by painting, and this is a commonly used material in bridges. It is the most commonly used grade of structural steel in the USA due to its high strength and toughness. It can also be certified to meet multiple standards such as ASTM A1035 or ASTM A572, among others.

ASTM A588 and S355J2WP are both weather resistant structures that can be used for bridges, pylons and other types of structures that are exposed to the atmosphere and other environmental conditions. In general, ASTM A588 has a higher corrosion resistance than S355J2WP due to the added copper in the chemical composition of the steel. However, S355J2WP has a lower tensile strength than A588, which means that it may not be as suitable for other applications that require a higher tensile strength. Both steels offer good protection against extreme weather conditions, making them suitable for use in infrastructure constructions that are exposed to weather extremes.
