Product Q&A

Q:How to specify unequal angle size?

Unequal angle specified by long side x short side x thickness (mm), e.g., 100x63x8 means 100mm long side, 63mm short side, 8mm thickness. Also by size number, e.g., 10/6.3# means 100mm long, 63mm short. Common sizes: 2.5/1.6#-20/12.5#.

Q:When to use unequal angle?

Use unequal angle when structural loading is asymmetric or connection positions need different widths on both sides. E.g., tower cross arms (long side bending, short side connection), vehicle frame reinforcement (long side load, short side connection), ship ribs (long side reinforcement, short side connection). Unequal angle saves 10-20% material vs equal angle in asymmetric positions.

Q:How to calculate weight?

Unequal angle weight (kg/m) = 0.00785 x [d x (B+b-d) + 0.215 x (r2-2r12)], simplified approx 0.00785 x d x (B+b-d). Example 100x63x8 approx 0.00785 x 8 x (163-8) = 9.73 kg/m (actual 9.88 kg/m).

Q:Can hot-dip galvanize?

Yes. Unequal angle hot-dip galvanized has 20-30 year anti-corrosion life, suitable for outdoor towers and vehicle structures. Recommend fabricate first then galvanize as whole.

Q:MOQ and lead time?

Common sizes stock 1 tonne MOQ 3-7 days, special size custom rolling 3 tonnes MOQ 15-30 days. Cutting, drilling, welding, hot-dip galvanizing etc. fabrication available.
