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

Yield Strength: 36,000 psi
Hardness: Not Rated (Medium)
Heat Treatable: Yes
Max. Hardness After Heat Treatment: Not Rated
Specifications Met: ASTM A36

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, such as fixture clamps, mounting plates, and spacers. This material can be surface hardened with heat treating.

Zinc-Galvanized Low-Carbon Steel 90° Angles

Yield Strength: 36,000 psi
Hardness: Rockwell B70 (Medium)
Heat Treatable: No
Specifications Met: ASTM A36

These 90° angles are zinc galvanized for good corrosion resistance. 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, such as fixture clamps and spacers.

Enclosure Drip Shields

Mounting Option 1

Mounting Option 2

Gray Powder-Coated Steel

Light Gray Powder-Coated Steel

Designed to hang over your enclosure door, these shields protect latches, handles, and other exterior hardware from dripping water and falling dust. Bolt them to the top of your enclosure with the included fasteners—the rubber washer seals the bolt hole to keep water and dust out of your enclosure.

Steel drip shields are powder coated, so they won’t rust under dripping water. Gray is also known as ANSI 61 gray, and light gray is also known as RAL 7035 gray.
