wrought iron angle weight calculator

Enter the dimensions of a wrought iron angle and this works out its volume and weight. Historic fibrous iron. Modern "wrought iron" gates are almost always mild steel.

Density used: 7750 kg/m3

Show the working

Leg A = 50
Leg B = 50
Thickness = 5
Length = 1000
Number of pieces = 1
volume_mm3 = (50*5 + (50 - 5)*5) * 1000 = 475 000
Volume of one piece = 475 000 / 1000 = 475
Density used = 7750 = 7750
Weight of one angle = 475 000 * 7750 / 1e9 = 3.681 25
Total weight = 3.681 25 * 1 = 3.681 25
Weight per metre of length = 475 000 / 1000 * 1000 * 7750 / 1e9 = 3.681 25

Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula

Volume = (A x t + (B - t) x t) x length, ignoring the root and toe radii
Weight = volume x density, with density = 7750 kg/m3
One cubic millimetre of a material at 1000 kg/m3 weighs exactly one milligram, so the millimetre-to-kilogram step is a shift of the decimal point rather than a rounded factor.

Historic fibrous iron. Modern "wrought iron" gates are almost always mild steel.

Dimensions are nominal. Mill tolerances on thickness, and the corner radii on formed sections, both move the real weight by a percent or two.

Every field takes inches or feet as readily as millimetres: change the unit next to it and the conversion is done exactly before the arithmetic starts.

Frequently asked

What is the density of wrought iron?

7750 kg/m3, which is 7.750 g/cm3. Historic fibrous iron. Modern "wrought iron" gates are almost always mild steel.

How do you calculate the weight of a wrought iron angle?

Volume = (A x t + (B - t) x t) x length, ignoring the root and toe radii. Multiply the volume by the density of wrought iron, 7750 kg/m3, taking care that both are in the same unit system.

Can I enter dimensions in inches?

Yes. Each dimension field has its own unit selector, and inch, foot, millimetre, centimetre and metre entries are all converted exactly before anything is multiplied.

Where the numbers come from

Densities are nominal room-temperature values for the grade named, drawn from the usual mill and handbook figures.
