Australian Steel Weight Calculator — UB, UC, PFC

Australian Steel Mass Calculator

Calculate the total weight of Australian steel sections per AS/NZS 3679.1. The calculator uses standard mass per metre values from the Australian section database with density 7850 kg/m³.

Supported Australian Sections

UB (Universal Beams) — 150 UB to 1100 UB, mass range 14.0–388 kg/m
UC (Universal Columns) — 100 UC to 360 UC, mass range 12.0–634 kg/m
PFC (Parallel Flange Channels) — 75 PFC to 430 PFC, mass range 5.9–73 kg/m
Equal and unequal angles — standard Australian angle sections
Plate — custom dimensions in mm

How to Use

Select the Australian section type (UB, UC, PFC, angle, or plate)
Choose the specific section size from the database
Enter the total length in metres
The calculator displays total mass (kg) and total weight (kN)

Worked Example

Problem: Calculate the total steel weight for 12 × 8.0 m long 530UB92.4 beams.

Solution:

Mass per metre: 92.4 kg/m (from section designation)
Total length: 12 × 8.0 = 96.0 m
Total mass: 96.0 × 92.4 = 8870 kg (8.87 tonnes)
Total weight: 8.87 × 9.81 = 87.0 kN

Result: 8.87 tonnes of steel — use this for transport, erection, and cost estimation.

FAQ

What density does the calculator use? Standard steel density of 7850 kg/m³ (7.85 t/m³) — consistent with AS/NZS 3679.1 and EN 10025.

Can I calculate plate weight in mm dimensions? Yes. Enter plate width, length, and thickness in millimetres. The calculator converts to metres and applies the standard density.

Are Australian and US sections the same weight? No. Australian UB sections follow metric mass designations (e.g., 92.4 kg/m for 530UB92.4) which differ from US W-shape imperial weights (lb/ft). The calculator handles both correctly based on code selection.
