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 HR2

GMW2M-ST-S HR2 is a draw quality grade hot rolled steel conforming to the gm material specifications.

This specification carries the GMW2M-ST-S HR2 is a hot-rolled deep-drawing-quality steel with enhanced elongation for complex underbody stampings like spare tire wells and rear floor pans.

Ameristeel stocks GMW2M-ST-S HR2 in a range of thicknesses and widths for structural and forming applications. As a hot rolled product, this specification is supplied in coils, cut sheets, or blanked parts. Our dedicated purchasing team sources GMW2M-ST-S HR2 through direct mill relationships, and every incoming coil is third-party tested under our ISO 9001:2015 quality management system.

GMW2M-ST-S HR2 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 HR2 depends on your forming process, paint system, and end-use corrosion environment.

GMW2M-ST-S HR2 is listed alongside GMW2M-ST-S HR1 and GMW2M-ST-S HR3 within this specification family. As a draw quality designation, GMW2M-ST-S HR2 addresses specific hot rolled forming requirements that distinguish it from adjacent grades in ductility, surface quality, and mechanical property control.

GMW2M-ST-S HR2 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 HR2 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 HR2 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, shear processing for rapid sheet production. 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.
