Formula Used

Mass = Cross-sectional area × Length × Density

For one beam, the calculator multiplies area in square metres by length in metres. It then multiplies volume by density in kilograms per cubic metre.

Weight force = Mass × Gravitational acceleration

The default acceleration is 9.80665 m/s². Mass and weight force are different quantities. Kilograms measure mass. Newtons measure force.

Total purchase mass = Adjusted beam mass × Quantity × (1 + Waste %)

Coating mass, manufacturing tolerance, connection weight, and purchase allowance are added when entered.

Shape formulas

Section	Area formula	Important checks
Solid rectangle	A = B × H	Width and height must be positive.
Solid round	A = πD² / 4	Diameter must be positive.
Rectangular hollow	A = BH − (B − 2t)(H − 2t)	Wall thickness must be less than half the smaller side.
Circular hollow	A = π(Dₒ² − Dᵢ²) / 4	Inside diameter must remain positive.
I-section	A = 2Bf tf + (H − 2tf)tw	Root radii are not included in the simplified custom formula.
T-section	A = Bf tf + (H − tf)tw	Flange thickness must be smaller than depth.
Angle	A = at + bt − t²	The overlap square is subtracted once.
Plate girder	A = Bt tt + Bb tb + (H − tt − tb)tw	Enter each flange separately.

Worked Example

Consider an IPE 300 steel beam. The reference mass is 42.2 kg/m. A six metre beam has a base mass of 253.2 kg. Four identical beams have a combined base mass of 1,012.8 kg. A three percent purchase allowance increases the order mass to about 1,043.184 kg.

The corresponding standard-gravity force is roughly 10.23 kN. This self-weight does not represent the safe load capacity. It is only the force caused by the beam mass.

Planning and Accuracy Notes

Standard sections may have rolling tolerances. Published masses can also include fillets, corner radii, and manufacturing conventions. Simplified custom formulas may omit those details. Coatings, moisture, fasteners, weld metal, end plates, stiffeners, and fire protection can materially increase transport weight.

Concrete and timber densities vary more than steel densities. Moisture content can strongly affect timber mass. Concrete mass depends on aggregate, reinforcement, and mix design. Always use project-specific supplier information for ordering, lifting, and transport planning.

The transport estimate divides total mass by the entered payload. It does not check legal axle limits, beam length restrictions, load distribution, route rules, crane radius, rigging angles, or lifting accessory capacity.

Frequently Asked Questions

Does this calculator determine beam strength?

No. It estimates mass and gravitational weight. Strength requires section properties, material grade, span, supports, load combinations, stability checks, connections, and code-based design.

Can I calculate aluminum or timber beams?

Yes. Select the material preset or use custom density. The same volume method applies, but actual material density may vary.

Why does a standard profile differ from my custom dimensions?

Standard tables may include root radii, corner radii, rolling tolerances, and exact published geometry. Simplified custom formulas usually omit fillets.

What is the difference between mass and weight?

Mass describes the amount of material and is commonly shown in kilograms. Weight is gravitational force and is shown in newtons or pound-force.

How should galvanizing be included?

Enter coated surface area per metre and an estimated coating mass per square metre. Supplier coating data gives the best estimate.

Can the schedule contain different materials?

Yes. Each schedule row has its own profile, material, length, quantity, and price. The row mass scales by the selected density.

Can I save a report as PDF?

Use Print or Save PDF. Modern browsers can create a PDF from the print dialog while preserving the result report.

Are the built-in profile values guaranteed?

No. They are reference values for calculation and comparison. Verify current section data with the applicable standard, mill, fabricator, or supplier.
