Our Products

Ace Steel Supply provides a comprehensive selection of flat-rolled products engineered to support manufacturers, fabricators, OEMs, construction companies, and service providers across a wide range of industries. Sourced from reputable mills, our materials deliver the consistency, quality, and reliability required to keep your production moving without interruption.

Hot Rolled (HR) Steel

Best for strength and cost – not for looks. Scaled, rough surface, looser dimensional tolerances, and more cost effective than cold-rolled. Ideal where appearance and tight tolerances are not critical.

Hot Rolled P&O (HRPO) Steel

Cleaned up HR – better for forming, painting, and tighter processes. Hot rolled steel that has been chemically pickled (acid bath) to remove mill scale, then lightly oiled to prevent rust. Results in a clean, smooth, matte surface that’s more consistent. Slightly higher cost than HR, still not as tight in tolerances as cold rolled.

Corten / Weathering Steel (WS)

Patina-forming weathering steel; rust-like finish.

Floor Plate (Diamond Plate)

Raised pattern; durable and wear-resistant; anti-slip. Ideal for heavy-duty flooring.

Cold Rolled (CR) Steel

Smooth, tight tolerances; high strength.

Galvanized (HDG) Steel

Zinc-coated steel for corrosion resistance. Good formability and consistent coating options. G30, G40, G60, G90, G210. Thickness range .009 – .1472.

Electro-Galvanized (EG) Steel

Uniform electroplated zinc coating, smoothest galvanized surface, excellent paintability.

Galvannealed (GA) Steel

Zinc-iron alloy coating; paintable. Ideal for painting, forming, welding. Uniform matter surface.

Galvalume (AZ) Steel

Aluminum-zinc alloy; longest corrosion performance among coated steels, excellent for exterior use.

Bonderized (BZ) Steel

Paint-ready phosphate-treated galvanized steel. Uniform matte grey finish.

Painted (PFS) Steel

Painted flat rolled steel is carbon or galvanized steel coil that has been pretreated, primed, and coated with a baked-on paint finish. Common coatings include: Polyester, SMP (Silicone Modified Polyester), PVDF / Kynar, Acrylic coatings, backer coats for improved.

Aluminum (Sheet & Coil)

Lightweight, corrosion-resistant, highly formable and conductive. Available in common alloys such as 3003, 5052, 6061.

Aluminum Extrusions

Extruded aluminum is produced by forcing heated aluminum alloy through a shaped die, creating long, uniform profiles with consistent cross-sections. Excellent strength to weight ratio.

Stainless Steel (Sheet & Coil)

Exceptional corrosion resistance, hygienic, durable and aesthetic. Available in multiple grades (303, 316, 430, etc.).

Stainless Steel Extrusions

Produced by pushing stainless alloys through a precision die at elevated temperatures, yielding high-strength, corrosion-resistant profiles with tight dimensional tolerances. Offer superior durability in demanding or corrosive environments.Exceptional corrosion resistance, hygienic, durable and aesthetic. Available in multiple grades (303, 316, 430, etc.).

Aluminized Steel

Aluminum-based coating for heat & corrosion resistance. Ideal for high-temperature environments.

Excess / Secondary Steel

Non-prime, mill excess or non-prime material offered at highly competitive pricing and costeffective for many applications. Secondary may include cosmetic imperfections, off-gauge or non-critical variances. Available across multiple product categories. Ideal for customers seeking cost savings without requiring certified prime specifications.
