Steel Weight Calculator

Calculate the approximate weight of common steel sections using dimensions, quantity and material rate.

Section Shape

Quantity

Rate per kg (Optional)

⌁

Estimate weld metal required based on weld leg size, weld length, number of welds and reinforcement factor.

Leg Size (mm)

Weld Length (mm)

Number of Welds

Reinforcement Factor

Calculation note: Throat area = leg² / 2. A factor of 1.2 allows for weld convexity. Use 1.0 for theoretical throat only.

🔩

Estimate the approximate weight of bolt assemblies including one nut and one washer per bolt.

Bolt Size

Bolt Length (mm)

Quantity

Note: Approximate calculation including one nut and one washer per bolt. Actual weight can vary by grade and standard.

⇄

Convert common engineering units for length, mass, force and stress.
