Mild Steel Equal Angle, a bent right-angle bar widely used in fabrication and construction for frames or racks and typically bolted or welded to a vertical face to form a shelf for support or bracing of a wall. Its L-shaped profile leads to its occasional references as “L” angle or “L” Bars, with “equal” indicating that the legs of the right angle have the same length.
EA Mill Finish, a 300PLUS® Grade Mild Steel by OneSteel – Liberty – GFG Alliance in Australia, is available in mill finish for hot-rolled Structural Steel and Merchant Bar sections, potentially displaying surface rust. Coatings are optional at an extra cost. The 300PLUS® Product line includes heavy and light structural steel (channels and beams – UBs), merchant bar products (rounds – squares – flats – rods – PFCs – TFBs – angles), and light billets (Square Bars). Equivalent products meeting Australian Standards may also use this product code.
Characteristics
Most mild steel equal angle bars are hot-rolled mill finish, characterised by a low-tolerance coarse finish with mill scale. Refer to the manufacturer’s guide to Hot Rolled Structural Steel Products for sizes, dimensions, weight information and mechanical properties, including yield strengths for Structural Steel Equal Angle bars.
Common Applications
Mild Steel Equal Angel bars can be cut, formed and bent, threaded, drilled and welded and have a range of applications, including:

Surface Preparation and Coatings
To comply with NCCC (BCA) and Australian Standards, consider industrial protective coatings for preventing atmospheric corrosion (rust). As a customer or user of structural steel angle equal, be aware of the Australian Building Codes guidelines covering steel coatings.
Our Hot-dip Galvanised Structural Steel angle equal adheres to the Australian Standard for Hot-dip Galvanized (zinc) coatings on fabricated ferrous articles (AS/NZS 4680) for both inside and outside. Find additional information about the Hot-Dip Galvanizing process here.
Consult your designer or certifier for additional guidance on Coatings of Structural Steel Beams. For more information on protecting structural steel from rust, refer to Part 1 (Paint coatings) and Part 2 (Hot dip galvanising) of AS/NZS 2312.
