When to Choose Unequal Angles Over Equal Angles
Unequal angles are recommended for structures where one leg must provide greater bearing area or support higher loads. They are also ideal for corner reinforcement, frame edges, and asymmetric mechanical structures.
Surface Treatment Options
Depending on environmental exposure, Unequal Steel Angles can be supplied black, painted, shot-blasted, or hot-dip galvanized. Dexter Steel provides customized coatings to meet international corrosion resistance requirements.
Frequently Asked Questions
Unequal angles are often selected for projects requiring directional load reinforcement, leading to questions regarding strength differences, fabrication behavior, and typical applications. These FAQs summarize the most common engineering concerns when specifying Unequal Steel Angle for structural frameworks and load-bearing assemblies.
Why choose an unequal angle instead of an equal angle?
Unequal angles offer directional stiffness and greater bearing capacity on one leg, ideal for asymmetrical load conditions
Are unequal angles suitable for welding?
Yes. Most are produced from weld-friendly structural grades such as Q235B, Q355B, and ASTM A36.
What sizes are commonly available?
Typical sizes range from 30×20×3 mm up to 200×125×20 mm or larger depending on grade and specification.
What industries use unequal angle steel the most?
Construction, machinery fabrication, shipbuilding, towers, and industrial equipment manufacturing.
Can unequal angles be galvanized?
Yes. Hot-dip galvanized and painted options are available for corrosion protection.
