Why Builders Think Angles Are “Weaker” Than Hollow Sections (They’re Not Always)
Just like last week’s SHS vs RHS confusion, where 50×50 became “RHS,” steel angles face a common myth: “Angles are just cheap brackets, use SHS for real strength.” In reality, angle iron (L-shaped steel) often outperforms square hollow sections (SHS) in bracing, connections, and torsion resistance due to its efficient stress distribution along the 90° bend. This misconception leads builders to over-specify heavier SHS, wasting money and weight. Melsteel helps you choose right every time.
Key Differences: Angles Excel Where SHS Struggles
| Feature | Steel Angles (L-Shape) | SHS (Square Hollow Section) |
|---|---|---|
| Shape | Two legs at 90° (equal or unequal) | Four equal sides, hollow core |
| Strength Edge | Superior torsion resistance; evenly distributes stress | High uniform compression but twists under torque |
| Best For | Bracing, frames, shelves, trailers, welds | Columns, posts, spans with multi-directional loads |
| Cost/Weight | Lighter & cheaper per strength; easy to fabricate | Heavier for equivalent bracing; pricier upfront |
| Myth Bust | Not “weak,” resists bending better in connections | Strong overall but overkill (and flexible) for edges |
Angles shine in shear-heavy applications like trailer frames or wall studs, where their open L-shape prevents buckling under twist, SHS can ripple or distort here. Equal angles suit symmetric corners; unequal ones provide ledges for shelves or one-sided fixes.
Melsteel’s Steel Angles: Sizes, Finishes & Full Support
Melsteel stocks equal and unequal angles in primed/galvanised finishes, from small 25x25x3mm to heavy-duty 100x100x10mm, cut to length. Use them for vehicle chassis, brackets, or reinforcing SHS frames, our fabrication team welds, folds, and delivers across Melbourne. No guesswork: Get expert specs to avoid the “angles are weak” trap.

FAQs: Steel Angles vs SHS Myths
1. Are steel angles weaker than SHS?
No. Angles resist torsion better for bracing; SHS wins uniform loads but costs more.
2. Equal vs unequal angles?
Equal for balanced corners; unequal for shelves/walls (long leg against surface).
3. Common angle uses?
Frames, trailers, lintels, and gates are cheaper than SHS for edges/supports.
