What is an angle bar?
An angle is a hot-rolled L-shaped section with two legs at 90°, equal (both legs the same, e.g. 50×50×5) or unequal (e.g. 100×65×8). It is the simplest structural shape and the cheapest per ton after flat bar, and it does everything from lattice towers and roof trusses to shelf frames: bracing, purlin cleats, tank stiffening rings, lintel supports, door and window frames, gratings and platform edges, machine guards, racking, fence and guardrail posts, and the diagonals of transmission towers (S355J2, galvanized). MS angle, angle iron and L bar are trade names for the same product.
Equal or unequal — the two angle pages
Equal angle bar (20×20 to 200×200) for bracing, towers and cleats; unequal angle bar (40×20 to 200×150) for lintels, stringers and edge members. Both pages list every size with kg/m and 12 m bar weight.

Frequently asked questions
What is an angle bar?
An L-shaped hot-rolled steel section with two legs at 90°, equal (50×50×5) or unequal (100×65×8), 20–200 mm, used for frames, trusses, towers, bracing, racking and general fabrication. Also called MS angle, angle iron or L bar.
What is the standard size for angle bars?
6 m bars (12 m on request) in sizes from 20×20×3 to 200×200×20 mm equal and 30×20 to 200×100 unequal; 40×40×4, 50×50×5 and 100×100×10 are the most ordered.
How much does a 50×50×5 angle weigh?
3.77 kg/m — 22.6 kg per 6 m bar, about 44 bars per ton. 40×40×4 = 2.42 kg/m; 100×100×10 = 15.0 kg/m.
How much angle bar is 1×1?
A 25×25×3 mm (≈ 1" × 1" × ⅛") angle weighs 1.12 kg/m (6.7 kg per 6 m bar) — about 149 bars per ton; price per bar from the band above.
Which is stronger, tubular or angle bar?
For the same weight a square hollow section is stiffer in bending and torsion; an angle is easier to bolt and cheaper per ton. Use angles for trusses, bracing and cleats, tubes for columns and frames.
Do you supply galvanized angles?
Yes — hot-dip galvanized to EN ISO 1461 (70–85 µm) after cutting and punching, for towers, masts, fences and outdoor frames; adds 25–35% and 5–7 days.
Can you punch tower angles?
Yes — punched and drilled to the tower or truss drawing on the angle line, S355J2, galvanized, bundled by mark number with bolts.
What is the price of angle bar per ton?
See the indicative FOB Istanbul band above for S235JR equal angles 25–150; small sizes, S355J2 and galvanizing add to it. Firm price within one working day.
