A36 A572GR50 Channel Beam

ASTM A36 Steel Plate is one of the most common grades of steel used in structural applications. This mild carbon steel grade contains chemical alloys that give it properties such as machinability, ductility, and strength that are ideal for use in constructing a variety of structures. ASTM A572 GR 50 is a high strength low alloy steel. Grade 50 is difficult to form since it contains more alloying elements than plain steel but offers more strength per unit of weight. Owing to its high strength ASTM A572 Grade 50 Plates requires less material to satisfy strength requirements than plain carbon steel.

Also known as heavy duty purlins, channel bars are recognizable as a long rolled bar forming a hard U shape – the flanges creating right angles on both sides. Its smaller variation is more commonly used for frame supports in automobiles. For bigger construction and bridge decks, the larger form of channel bars can be used, harnessing its ability to absorb flex and rigid force that might damage I-beams or H-beams.
