Specifications and dimensions
- Identify equal or unequal angle by leg widths, thickness, root radius and ordered length.
- State leg and thickness tolerances, squareness, camber, twist, end condition and hole or cut requirements.

ASTM A572 Grade 50 Steel Angle
ASTM A572 Grade 50 steel angle for higher-strength structural work; thickness, section, toughness and fabrication requirements remain project-specific.
03Grade-product
Standards and supply condition
- ASTM A572/A572M Grade 50 material specification
- ASTM A6/A6M general requirements for the applicable rolled product
Manufacturing and processing
- Angles are normally hot rolled; cold-formed or welded angles must be identified because geometry and residual stress differ.
- Cutting, punching, drilling, galvanizing and fabrication can change edge, hole and distortion acceptance.
Typical applications
- Bracing, frames and secondary structural members
- Towers, racks, platforms and equipment supports
- Connection and edge members in fabricated assemblies
Quality and acceptance controls
- Match grade, heat number, product form, dimensions and ordered ASTM edition to the mill test report.
- Verify dimensional tolerances, straightness or flatness, surface condition, marking and traceability under ASTM A6/A6M.
- Order impact testing, ultrasonic examination, carbon-equivalent reporting or other supplementary requirements when the design requires them.
Include in your RFQ
- Exact alloy or grade and governing product specification
- Product form, dimensions, tolerances and quantity
- Delivery condition or temper and required surface finish
- Fabrication route, service environment and design standard
- Testing, inspection, certificate and traceability requirements
- Packing, marking, destination and required delivery date
Selection limits
- The grade does not by itself establish structural capacity, notch toughness, weld procedure, corrosion protection or suitability for a specific code.
- Plate, sheet, bar and structural shape availability and property limits vary with thickness, section and the current product standard.
