Work out the monthly instalment for a purchase or project loan using the standard reducing-balance formula.

Indicative figures only. Your lender may add processing fees, taxes, or insurance.

Pick a profile, enter the section dimensions, and get the weight per meter, per piece, and for the whole order.

Weights are calculated from the nominal geometry and exclude root radii, tapers, and rolling tolerances.

Circular cross-section weight for rebar, bright bar, and round stock.

Cross-section area = pi / 4 x diameter squared.

Equal and unequal angle weight from the two leg sizes and the leg thickness.

Cross-section area = thickness x (leg A + leg B - thickness). Root radii are ignored.

Approximate weight for C and U channels from the web and flange dimensions.

Cross-section area = web + two flanges. Root radii and flange tapers are ignored, so rolled-section tables may differ slightly.
