Overview of Equal Leg Angle Steel
Equal Leg Angle Steel, commonly referred to as Equal Angle, L-Section, or L-Shape, is a hot-rolled structural steel section with an L-shaped cross-section where both legs are of equal length. Equal leg angles are one of the most fundamental and widely used structural steel profiles in global construction, fabrication, and industrial applications. They are available in a broad range of leg sizes and thicknesses, designated by leg width and thickness such as L50×50×5, L100×100×10, or L150×150×15, and are produced according to multiple international standards including EN 10056-1, ASTM A36, JIS G3192, GB/T 706, and AS/NZS 3679.1.
Equal leg angle steel is valued for its versatility, economical cost, ease of fabrication, and ability to function as both structural and secondary members across a wide range of applications. The symmetric L-shaped cross-section provides efficient resistance to tension, compression, and shear in structural frames, trusses, bracing systems, and connection assemblies. Equal angles are commonly supplied in S235JR, S275JR, S355JR, A36, SS400, Q235B, and Q345B steel grades, covering standard and high-strength structural requirements for construction, industrial, marine, and infrastructure projects worldwide.
Key Features and Manufacturing Process
Equal Leg Angle Steel is manufactured through the hot rolling process, where heated steel billets are passed through L-shaped section rolls to form the characteristic equal-leg L-profile. The rolling process produces consistent leg width, leg thickness, root radius, and toe radius as specified by the applicable dimensional standard. EN 10056-1 governs European equal angle sections, ASTM A6 covers American sections, JIS G3192 defines Japanese standard angles, and GB/T 706 specifies Chinese standard equal angles.
Equal angles are available in a comprehensive size range from small sections such as 20×20×3 for light fabrication to large sections such as 250×250×35 for heavy structural applications. Leg widths typically range from 20mm to 250mm, with leg thicknesses from 3mm to 35mm within the standard section tables. Standard lengths are 6m and 12m, with custom cut-to-length available. Steel grades include S235JR, S275JR, S355JR per EN 10025-2, ASTM A36 and A572 Grade 50 per American standards, SS400 and SM490 per JIS, and Q235B and Q355B per GB standards. Surface treatments including shot blasting, primer painting, hot-dip galvanizing, and anti-rust oil coating are available for corrosion protection.
Main Applications of Equal Leg Angle Steel
Equal Leg Angle Steel is used across virtually every sector of structural and industrial construction due to its versatility and economical profile. In building and civil construction, equal angles are used for structural trusses, bracing members, column stiffeners, connection gussets, lintels, shelf plates, edge protection, framing connections, cable tray side rails, and general structural reinforcement.
In industrial and infrastructure applications, equal leg angles are widely used for crane support structures, conveyor frame members, equipment support brackets, machine bases, mining structure members, ladder stringers and rungs, scaffolding frames, ship structural members, dock fenders, marine structure secondary members, bridge cross-bracing members, tower and mast structural members, transmission line tower members, railway track guards, agricultural building frames, greenhouse structures, and a wide range of general steel fabrication applications where L-shaped sections provide practical structural and connection solutions.

📦 Commercial Information
| Packaging | Standard seaworthy export packing for Equal Leg Angle Steel sections. Angles are bundled with steel strapping in bundles of 2-5 tons depending on leg size and length. Each bundle is clearly tagged with heat number, grade designation, angle section size, length, and quantity for full material traceability. Wooden separators and dunnage are placed between bundle layers to prevent surface damage during handling and transport. Smaller angle sections can be loaded in standard 20ft or 40ft containers. Larger sections such as L200 and L250 and long lengths may require open-top containers, flat racks, or break-bulk vessel loading. Anti-rust oil coating is recommended for bare mill surface export shipments. |

❓ Frequently Asked Questions
What is Equal Leg Angle Steel?
Equal Leg Angle Steel is a hot-rolled structural steel section with an L-shaped cross-section where both legs are of equal length. It is designated by leg width and thickness such as L100×100×10. Equal angles are produced to EN 10056-1, ASTM A6, JIS G3192, and GB/T 706 standards and are one of the most widely used structural profiles in global construction and fabrication.
What is the difference between equal angle and unequal angle steel?
Equal leg angle has both legs of the same length, providing a symmetric cross-section suitable for members where equal strength in both directions is required. Unequal leg angle has two legs of different lengths, providing higher bending resistance about one axis, making it suitable for applications where the section is loaded primarily in one direction. Equal angles are more commonly used due to their versatility and wider availability.
What steel grades are available for equal leg angle steel?
Standard grades include S235JR, S275JR, and S355JR per EN 10025-2, ASTM A36 and A572 Grade 50 per American standards, SS400 and SM490 per JIS standards, and Q235B and Q355B per GB standards. The appropriate grade depends on project design requirements and applicable standards.
What sizes are available for equal leg angle steel?
We supply equal leg angle sections from 20×20×3 to 250×250×35, covering light fabrication sections through to heavy structural members. Standard lengths are 6m and 12m, with cut-to-length service available for project-specific requirements.
What are the main structural uses of equal leg angle steel?
Equal angles are used for structural trusses, lattice frames, bracing members, column stiffeners, connection gussets, crane support members, conveyor frames, transmission tower members, mining structure components, ship structural members, ladder stringers, scaffold frames, railway track guards, and general steel fabrication.
What surface treatments and certifications are available?
Surface treatments include Bare / Mill Surface, Shot Blasting (Sa2.5), Painting (Red Primer), Hot-dip Galvanized, and Anti-rust Oil Coated. Certifications available include EN 10204 3.1, EN 10204 3.2, Original Mill Certificate, Third Party Inspection, and Certificate of Origin. Classification society certificates from ABS, DNV GL, LR, and BV can be arranged for marine and offshore projects.
