Galvanized and Coated Carbon Steel Coil Products

At Reliance Metalcenter, we stock and process galvanized steel coil and coated carbon steel coil in a wide range of sizes, coating weights, and finishes. Our materials come from trusted steel coil manufacturers and are certified to meet demanding industry standards for performance and consistency.

Galvanized Steel Coil

Hot-dipped galvanized coils are zinc-coated for corrosion resistance and durability. Common uses include:

• Roofing and architectural panels
• HVAC ductwork and framing
• Automotive body panels
• Agricultural machinery
• Utility enclosures and trailer frames

This material is ideal for applications requiring long-term resistance to moisture, chemicals, or exposure to the elements.

Coated Carbon Steel Coil

We offer a variety of coated steel options, including:

• Aluminized coatings for heat resistance and thermal protection
• Electro-galvanized steel for precision applications needing a smooth, uniform surface
• Galvannealed coatings that combine rust resistance with excellent paint adhesion

These products are suited for appliance manufacturing, energy infrastructure, automotive interiors, lighting systems, and structural parts.
