Commercial Quality, DQ, and AKDQ Galvanized Steel: Versatile, Reliable, and Always In Stock
If you need dependable, formable galvanized steel for everyday fabrication, CQ steel is a smart choice. At Hascall Steel, we supply Commercial Quality (CQ), Drawing Quality (DQ), and Aluminum Killed Drawing Quality (AKDQ) galvanized coils and sheets that meet ASTM A653 standards. Available in a range of thicknesses and zinc coatings, these grades give manufacturers the right balance of strength, formability, and corrosion resistance.
Whether you’re making HVAC components, brackets, appliance panels, or roll‑formed parts, our CQ steel, DQ steel, and AKDQ steel are always in stock and ready to meet your production needs.
What Is CQ Galvanized Steel?
CQ, or Commercial Quality, is a low‑carbon galvanized steel grade designed for general forming and bending applications. Zinc‑coated using the hot‑dip process per ASTM A653, it provides long‑lasting corrosion protection. CQ steel is ideal for projects that don’t require deep drawing or high structural strength.
How DQ and AKDQ Steel Compare
While CQ steel handles most light‑to‑moderate forming needs, some applications demand greater drawability:
- DQ steel (Drawing Quality) offers enhanced formability for moderate to deep drawing operations.
- AKDQ steel (Aluminum Killed Drawing Quality) is vacuum‑degassed for improved consistency and surface quality, making it the preferred choice for the deepest draws and highest cosmetic requirements.
Hascall Steel stocks all three grades, CQ, DQ, and AKDQ so you can select the right option for your part geometry, forming depth, and end use.
Key Features of CQ, DQ, and AKDQ Galvanized Steel
- Excellent formability for bending, roll forming, and shaping
- CQ steel for general‑purpose forming, DQ steel for moderate drawing, AKDQ steel for deep drawing
- Zinc‑coated for corrosion resistance
- Consistent flatness and surface quality
- Available in coating weights G30, G40, G60, G90
- Meets ASTM A653 specifications
- Custom‑slit or cut‑to‑length to your specs
Common Applications
Our galvanized steel grades are used across industries for parts requiring versatility and durability:
- HVAC ductwork and fittings (CQ steel)
- Appliance panels and backs (CQ or DQ steel)
- Automotive underbody shields and non‑critical parts (CQ steel)
- Appliance faces and visible panels (DQ or AKDQ steel)
- Deep‑drawn housings and enclosures (AKDQ steel)
If your application doesn’t require deep drawing, commercial quality steel is often the most cost‑effective choice.
