Specifications and dimensions

Equal- and unequal-leg angle ordered by leg widths, thickness, and length
Hot-rolled, laser-welded, press-brake formed, or cold-formed construction identified
Leg, squareness, twist, straightness, radius, and length tolerances agreed

Standards and supply condition

ASTM A276/A276M where applicable
ASTM A484/A484M general requirements
EN 10088-3 material requirements

Manufacturing and processing

Section geometry may be rolled, formed from plate or sheet, or fabricated by welding depending on size and availability.
Heat tint removal, pickling, passivation, grinding, and polishing are separate finish requirements.

Typical applications

Frames and supports
Architectural trim
Food and chemical equipment
Marine and water-treatment structures

Quality and acceptance controls

Verify the heat or coil number and material test certificate against the ordered grade and product standard.
Confirm dimensions, tolerances, surface condition, permitted repair, marking, and traceability.
Agree inspection, export packing, moisture protection, document language, and third-party witness points before production.

Include in your RFQ

Grade and governing product specification
Dimensions, tolerances, and ordered quantity
Condition, finish, edge, end, or processing route
Required testing, inspection, and certification
Packing, marking, and traceability requirements
Destination and required delivery date

Selection limits

Grade name alone does not define product form, governing specification, dimensions, finish, inspection, or fitness for the service environment.
Published ranges and reference guidance are not stock promises or purchase acceptance criteria; the ordered specification and certificate control.
