GM Material Specifications

General Motors (GM) material standards — including GMW2M-ST-S and GMW3032M/3399M designations — define steel grades for GM vehicle platforms. Ameristeel supplies GM-specified cold rolled and hot rolled steel in drawing quality, bake-hardenable, HSLA low-alloy, and advanced high-strength dual-phase (AHSS) grades with galvanized, galvanneal, and electrogalvanized coating availability. These specifications govern material selection for body panels, structural reinforcements, and crash-management components across GM's vehicle lineup. Stocked in coils and sheets at our Fraser, MI facility, with blanking, slitting, and cut-to-length processing for prototype builds and high-volume production orders.

About GMW2M-ST-S CR1

GMW2M-ST-S CR1 is a commercial quality/draw quality grade cold rolled steel conforming to the gm material specifications.

This specification carries the GMW2M-ST-S CR1 is a commercial-quality cold-rolled steel with standard elongation for simple bending and roll forming, typically used for brackets, channels, and non-critical inner reinforcements.

Ameristeel maintains a deep inventory of GMW2M-ST-S CR1 in standard and custom gauges, available as coils, slit coils, sheets, or precision blanks. As a cold rolled product, GMW2M-ST-S CR1 offers the tight thickness tolerances and controlled surface finish critical for visible and semi-exposed automotive applications. Every coil is third-party tested under our ISO 9001:2015 quality system.

GMW2M-ST-S CR1 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 GMW2M-ST-S CR1 depends on your forming process, paint system, and end-use corrosion environment.

GMW2M-ST-S CR1 is listed alongside GMW3032M-ST-S CR240LA within this specification family. As a commercial quality/draw quality designation, GMW2M-ST-S CR1 addresses specific cold rolled forming requirements that distinguish it from adjacent grades in ductility, surface quality, and mechanical property control.

GMW2M-ST-S CR1 is an OEM-specific grade developed to meet General Motors engineering requirements for vehicle body and structural applications. Ameristeel supplies General Motors-specified steel grades directly to Tier 1 and Tier 2 automotive suppliers throughout Southeast Michigan, with full material traceability and third-party test reports on every coil. Our Fraser, MI steel processing facility maintains dedicated inventory of GMW2M-ST-S CR1 to support just-in-time delivery schedules, and our ISO 9001:2015 quality system ensures that every shipment meets the exact mechanical property, surface quality, and dimensional tolerances required by General Motors production standards.

Ameristeel offers in-house processing for GMW2M-ST-S CR1 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.
