Angles

Structural Angles have an L-shaped cross section that is used in many structural steel applications.  Standard Lengths are 20′ and 40′.  Infra-Metals offers many different sizes, lengths and specifications for Structural Angles

Specifications

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 primarilyfor 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.
