ASTM Carbon Steel Angle Bar: Dimensions, Grades and Applications

ASTM angle bar, also known as angle steel, is one of the most popular steel products in the international industries and infrastructure markets. Angle bars conforming to ASTM standards offer outstanding strength, stability, and flexibility, which makes them ideal for an extensive number of load support and bearing uses.

Common ASTM Grades

Several ASTM grades are widely applied in angle bar production, including:

ASTM A36 Angle Bar – General purpose A36 plate is a plain carbon steel plate, which is suitable for welding, riveted, or bolted.

ASTM A572 Grade 50 Angle Bar – High-strength, low-alloy steel with better strength-to-weight ratio than A36, used in bridges and heavy structures.

ASTM A992 Angle Bar – Used in structural framing where uniform mechanical properties are desired.

These specifications enable engineers and contractors to choose angle bars according to the strength, weldability and standard design requirements.

Key Applications

ASTM angle bars are widely applied in various industries such as:

Building construction: Structural frames, columns, roof trusses, and bracing systems

Infrastructure projects: Bridges, transmission towers, ports, and highways

Industrial facilities: Equipment supports, platforms, and machinery frames

Energy and utilities: Power plants, renewable energy structures, and substations

With their straightforward design and high strength, angle bars are a economic solution for both permanent and temporary structures.
