ASTM Standards

American Society for Testing and Materials (ASTM) standards govern steel quality, testing methods, and mechanical performance requirements. Ameristeel supplies a broad range of ASTM-graded flat-rolled steel products from our Fraser, MI facility, including cold rolled and hot rolled forming steels, galvanized and galvanneal coated grades, HSLA structural grades, and improved-formability variants. Available in coils, sheets, and processed blanks with slitting and cut-to-length services for prototype runs and high-volume production alike. ASTM specifications are the benchmark for steel procurement across automotive stamping, construction, and industrial manufacturing sectors throughout Warren, Sterling Heights, and greater Southeast Michigan.

About ASTM A653/A653M CS TYPE B

ASTM A653/A653M CS TYPE B is a commercial quality grade galvanized steel conforming to the astm standards.

Type B specifies steel produced to standard deoxidation practice, suitable for unexposed structural applications where aging resistance is less critical.

Ameristeel supplies ASTM A653/A653M CS TYPE B with factory-applied corrosion protection in coil, sheet, and blank formats across a range of gauges and widths. Our galvanized inventory is sourced directly from domestic mills and third-party tested upon receipt at our ISO 9001:2015 certified facility to confirm coating weight, adhesion, and base metal mechanical properties.

ASTM A653/A653M CS TYPE B is supplied with the following coating options: hot-dip galvanized (zinc) for general corrosion resistance; galvanneal (zinc-iron alloy) for superior paint adhesion and weldability; electrogalvanized for precise coating weight control and smooth surface finish. The right coating choice for ASTM A653/A653M CS TYPE B depends on your forming process, paint system, and end-use corrosion environment.

ASTM A653/A653M CS TYPE B is listed alongside ASTM A653/A653M FS TYPE A and ASTM A653/A653M CS TYPE A within this specification family. As a commercial quality designation, ASTM A653/A653M CS TYPE B addresses specific galvanized forming requirements that distinguish it from adjacent grades in ductility, surface quality, and mechanical property control.

ASTM A653/A653M CS TYPE B is widely used across outdoor structural applications, HVAC ductwork, agricultural equipment, roofing and siding, and corrosion-resistant industrial components. Ameristeel sources and stocks this grade at our Fraser, MI steel processing center, with the ability to supply production quantities, prototype runs, and custom-processed orders. Whether you need full coils, slit-to-width coils, cut-to-length sheets, or precision blanks, our team can fulfill orders to ASTM A653/A653M CS TYPE B specifications with complete mill test reports and material certification.

Ameristeel offers in-house processing for ASTM A653/A653M CS TYPE B at our Warren and Fraser, Michigan facilities. Available processing capabilities include precision slitting to custom widths on our multi-cut blanking line, cut-to-length sheet processing for exact dimensional requirements, laser cutting for complex profiles and prototypes on our TRUMPF fiber laser systems, press brake forming on our TruBend series with up to 110-ton capacity and 120" bend length. From raw material sourcing through finished part delivery, Ameristeel provides a single-source solution — eliminating the need to coordinate between separate steel suppliers, service centers, and fabrication shops.
