Equal and unequal aluminium angles

An aluminium (aluminum) angle is an L-shaped extrusion with two legs at 90 degrees. In an equal angle both legs have the same length. In an unequal angle the legs differ, while the thickness stays the same. Buyers also search for them as angle bar, L section, L profile and corner profile.

Quick answer A 50 x 30 x 4 mm unequal angle weighs about 0.82 kg per metre. Weight = t x (A + B minus t) x 0.0027.

Unequal angle sizes (leg A x leg B x thickness, mm)

Size (mm)	Weight (kg/m)	Area (mm2)
25 x 15 x 3	0.30	111
30 x 20 x 3	0.38	141
40 x 25 x 3	0.50	186
50 x 30 x 4	0.82	304
60 x 40 x 5	1.28	475
75 x 50 x 6	1.93	714

Equal angle sizes

Size (mm)	Weight (kg/m)	Area (mm2)
25 x 25 x 3	0.38	141
40 x 40 x 4	0.82	304
50 x 50 x 5	1.28	475
75 x 75 x 6	2.33	864

Theoretical weight with sharp corners at 2.70 g/cm3. Metric and special sizes can be made on request.

Where angles are used

Corner protection and edge trim
Frames, braces and brackets
Shelving, racks and cabinet supports
Window and door fittings
Vehicle and trailer body parts
Support angles for panels and glass

Equal or unequal?

Use an equal angle for general bracing and symmetrical frames. Use an unequal angle when one face must carry a wider part, such as a shelf or a panel, while the other only needs to fix to a wall.

Why Snalco

Own extrusion plant at Kosamba, Surat, built around a 1600 UST four-column hydraulic press that handles 6 inch and 7 inch billets.
An in-house tool shop, so new dies and die corrections do not wait on an outside vendor.
Cutting to length, drilling, punching and machining done at the plant, so you can receive parts ready to fit.
ISO 9001:2015 certified manufacturing, with checks on raw material, during production and before dispatch.

How to order

Section and size: dimensions in mm, wall thickness, and the profile number or drawing.
Alloy and temper: for example 6063-T5, or 6061-T6 where more strength is needed.
Finish: mill finish, anodised, powder coated or another finish from the list above.
Length and quantity: cut lengths in mm or full mill lengths, and the total weight or number of pieces.
Delivery point: a city in India or an export port, so freight and packing can be quoted.

Frequently asked questions

What is the difference between equal and unequal aluminium angle?

Equal angle has two legs of the same length. Unequal angle has legs of different lengths with the same thickness.

How do I calculate angle weight?

Thickness x (leg A + leg B minus thickness) gives area in mm2. Multiply by 0.0027 for kg per metre.

Is aluminium corner profile the same as angle?

A corner profile is usually a smaller or decorative angle used to protect or finish an edge. It is made the same way.

What is the price of aluminum angle bar?

It depends on the metal rate, alloy, finish and quantity. Send your sizes for a quote.
