About Carbon Steel, Alloy Steel, Spring Steel, and Cast Iron

These sheets and bars are zinc galvanized for good corrosion resistance. Also known as mild steel, low-carbon steel is easy to machine and form. It's widely fabricated into parts that don’t require high strength, such as enclosures, brackets, and mounting plates. All have been manufactured to meet ASTM A653, ASTM A123, or ASTM A108 standards for quality and performance.

Zinc-coating weight designation indicates the level of corrosion resistance. A higher number means there’s a thicker coating and greater corrosion protection.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Mold- and Mildew-Resistant Low-Carbon Steel Sheets

Yield Strength: 40,000 psi
Hardness: Rockwell B55 (Soft)
Heat Treatable: No
Specifications Met: ASTM A653

A silver-filled resin coating on one side of these sheets protects from degradation caused by bacteria and fungi. Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength.

Zinc Sheets

Considered commercially pure, this material is 99% zinc.

Use foil as an alternative to lead for sound barriers and vibration dampers, as well as for EMI-RFI shields and architectural sheeting.

Use sheets to make parts that draw corrosion away from nearby metal in water tanks, heat exchangers, and marine applications. They meet MIL-A-18001 for chemical composition, so they break down faster than other types of metal. Attach them directly to the materials you want to protect.

Metal Panels

Close off openings in structures while allowing air to pass through.

For technical drawings and 3-D models, click on a part number.

Expanded Panels—Flattened

Expanded panels are more rigid than perforated panels and are for use when structural stability is important. They can be formed and welded; however, they are more difficult to cut than perforated panels. Flattened panels begin as raised panels, then they're rolled to a smooth and flat finish. Use them to create protective enclosures, shelving, grilles, and baskets.

Steel is lightly oiled.

Galvanized steel has good corrosion resistance in wet environments and can be used outdoors.
