Our CQ Steel Products
Many manufacturers need a steel product that delivers reliable performance without the added cost of specialty grades. Commercial Quality (CQ) steel fills that role. Its low carbon content provides the ductility required for moderate forming and bending, while its hardness and strength make it suitable for applications in the automotive, construction, and heavy truck industries. For projects where extreme drawability is not a requirement, CQ steel is often the most cost-effective option. As a full-service Commercial Quality (CQ) steel supplier, Millennium Metals offers the following CQ products:
- Steel plates: We supply CQ steel plate in standard and nonstandard sizes, with hot-rolled (HR) and shot-blasted options available. As your CQ steel plate supplier, we can cut to your exact specifications.
- Steel sheets: Millennium offers CQ hot-rolled (HR) and pickled & oiled (P+O) steel sheets with widths ranging from 48" to 72". As a CQ steel sheet supplier, we can cut lengths to fit your requirements.
- Steel coil: CQ steel coil is available in a range of gauges and finishes. Millennium can provide unique gauges and specifications upon request.
All CQ steel products ship with mill certifications. We also offer a stocking program and processing services to support your production schedule.

Frequently Asked Questions
What is the difference between CQ steel and Drawing Quality (DQ) steel?
CQ steel is designed for general-purpose fabrication where light to moderate forming is required, such as bending, roll forming, and welding. Drawing Quality (DQ) steel has a lower carbon content and greater ductility, making it better suited for applications that involve moderate to deep drawing operations. If your parts do not require significant stretching or deep draws, CQ steel is typically the more economical choice.
What ASTM standards does CQ steel fall under?
CQ steel is covered under ASTM A1011 for hot-rolled products and ASTM A1008 for cold-rolled products, where it is designated as Commercial Steel (CS). These standards define the chemical composition and mechanical property requirements that ensure consistent quality across production runs.
Can CQ steel be galvanized or coated?
Yes. CQ steel is commonly used as the base material for hot-dip galvanized products under ASTM A653. The zinc coating provides long-lasting corrosion protection, which makes galvanized CQ steel a popular choice for outdoor and moisture-exposed applications like HVAC components, roofing panels, and agricultural equipment.
