I-beams, also known as H-Beams have and I or H cross section. The horizontal elements of the “I” are flanges while the vertical element is the “web”. I-Beams are commonly made of structural steel but can be formed out of aluminum. I-beams are most widely used in construction and can have an application for use in both beams as well as columns. Infra-Metals offers many different sizes, lengths and specifications for I -beams.
Customer satisfaction built with steel
ASTM A36 – Standard specification for carbon structural steel. This specification covers shapes of structural quality for use in riveted, bolted, or welded construction of bridges and buildings, and for general structural purposes.
ASTM A572 – Standard specification for high-strength low-alloy structural steel. This specification covers five grades of high-strength low-alloy shapes intended for riveted, bolted, or welded construction of bridges, or for other construction applications.
ASTM A588 – Standard specification for high-strength low-alloy structural steel. This specification covers shapes for welded, riveted, or bolted construction but intended primarily for use in welded bridges and buildings where savings in weight or added durability is important. The atmospheric corrosion resistance of this steel in most environments is substantially better than that of carbon steels with or without copper addition.
ASTM A709 – Standard specification for carbon and high-strength low-alloy shapes. This specification covers shapes, and bars intended for use in bridges. Seven grades are available in four yield strengths.
ASTM A992 – Standard specification for steel for structural shapes for use in building framing. This specification covers rolled shapes for use in building framing or bridges, or for general structural purposes.
