International Certification and Standards for A588 Grade B Weathering Steel

A588 Grade B weathering steel is a high-strength low-alloy structural steel plate commonly used in heavy construction and industrial applications. It has excellent weldability and formability characteristics, and is easy to manufacture, making it a popular and economical choice for applications where weight reduction is important. Like all weathering steel alloys, A588 Grade B has a number of advantages that make it ideal for a variety of industrial applications such as bridges, buildings, facades, water towers and utility pole infrastructure.

ASTM A588 Grade B is the ASTM designation for this material. We have a long history of supplying A588 Grade B to projects that require durable specifications and consistent quality over a long period of time. As a structural cold-rolled steel, A588 Grade B exhibits improved atmospheric corrosion resistance. It is typically furnished as-rolled with a minimum Charpy V-notch impact energy of 27J at -20°C (Fracture Toughness).

The charcoal gray oxide film that forms on A588 Grade B provides a rust-inhibiting coating that is particularly effective in guarding against corrosive elements such as salt, water, rain and snow. The coating provides a protective layer that is molecularly bonded to the steel substrate which can withstand extreme environmental conditions and is self-healing in the presence of natural air humidity.

We have developed standards for A588 Grade B Weathering Steel that adhere to the American Society for Testing and Materials (ASTM) A-588 Grade B standards. Furthermore, our standards aim to ensure that the quality of A588 Grade B meets the requirements of construction jobs and projects that require long-term use with minimal corrosion.

These standards are based on the AHSS (Advanced High Strength Steel) recognition and include a number of measures of performance that go beyond the ASTM A-588 Grade B standards. This includes requirements for corrosion-resistant finishing, improved corrosion resistance, weathering characteristics and greater toughness than what is found in a standard Grade B steel.

Additionally, we follow International Organization for Standardization (ISO) testing standards and guidelines. Quality control is carried out according to ASTM A-588 Grade B standard as well as ISO TS 16949 to ensure high quality products. Finally, Kolev Insulated offers third-party certification to verify compliance with design standards, providing customers with assurance of product quality and sustainability.

Ultimately, our standards make A588 Grade B weathering steel the ideal solution for customers concerned with long-term performance without sacrificing quality.
