ASTM A572 High Strength Low Alloy Columbium-Vanadium Structural Steel

 

ASTM A572 high strength low alloy structural steel shapes. The common section steel in welded construction includes H-beams, channels, steel angles,I-beams. For applications, such as welded bridge construction, where notch toughness is important, notch toughness requirements are to be negotiated between the purchaser and the producer.

Grades 42 [290], 50 [345], 55 [380] are intended for riveted, bolted, welded structures.

Grades 60 [415],65 [450] are intended for riveted or bolted construction of bridges, or for riveted, bolted, or welded construction in other applications.

H-beams

H-beams are steel beams made of rolled steel in the shape of the letter "H". They are manufactured as combined units. Flanges are welded to the web to form an H-section. H -beams are also known as wide flange beams. According to the flange width of the H beam, it is divided into wide flange, middle flange and narrow flange H-beams. It is suitable for various civil and industrial building structures, very kinds of large-span industrial plants and modern high-rise buildings, especially in areas with frequent seismic activity and industrial plants under high-temperature working conditions, large bridges with large bearing capacity, good section stability and large span are required, heavy equipment, high speed way, ship skeleton, mine support, foundation treatment and dam works and machine components.

 

 

Additionally, we can provide angle steel and channel steel for our clients.

 

Angle steel

Angle steel, also called as angle iron, is a long strip of steel with two sides perpendicular to each other, including equal angle steel and unequal angle steel. The very name suggests that the two sides of an equilateral angle are equal in width. Angle steel is widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, hoisting and transportation machinery, ships, industrial furnaces, reaction towers,container racks and warehouse shelves.

 

 

Channel steel

Channel steel,known as “C” section steel, is a long strip of steel in the shape of a groove, shown as h x b x d. Channel steel is mainly used for building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.
