A-36 / A572-50 HR Structural Steel Channel

Alro stocks A-36/A572-50, a dual-certified carbon hot-rolled steel channel. It meets the requirements of both ASTM A-36 and ASTM A572-50. A-36/A572-50's strength, form-ability, and excellent welding properties make it suitable for a large variety of different applications. A-36/A572-50's yield strength is increased to 50,000 psi (higher than that of a normal A-36). Because of this, A-36/A572-50 is often used in structural applications that require higher strength than standard A-36. A-36/A572-50 can also be galvanized to provide increased corrosion resistance.

Tensile: 65 ksi min
Yield: 50 ksi min
Typical Uses
A-36/A572-50 is considered a "workhorse" grade and is widely used in many applications. Steel mills produce channel and heavy beams with Grade 50.
It is commonly used in structural applications, heavy construction equipment, building structures, heavy duty anchoring systems, truck frames, poles, liners, conveyors, boom sections, structural steel shapes, and applications that require high strength per weight ratio.
