What is the density used for stainless steel?

Austenitic grades (304, 316) use 7,900 kg/m³. Ferritic/martensitic grades (430, 410) use 7,750 kg/m³. Duplex grade 2205 uses 7,800 kg/m³. These are standard engineering reference values.

What is the difference between I-beam and H-beam?

An I-beam (S-section) has tapered flanges and a narrower profile, while an H-beam (W-section or wide flange) has parallel flanges of equal or greater width than the web height. H-beams generally carry heavier loads.

How accurate is the weight calculation?

The calculation uses the nominal cross-section geometry you enter. Real-world beams may vary slightly due to rolling tolerances, mill scale, or coatings. For critical applications always verify against the mill certificate.

Can I use this for carbon steel beams?

The tool is designed for stainless steel grades. Carbon steel has a slightly different density (~7,850 kg/m³). For a rough estimate with carbon steel, select grade 304 (7,900 kg/m³) — the error is less than 1%.

What units does the calculator support?

You can input dimensions in millimeters with length in meters (metric), or switch to inches and feet (imperial). Weight output is in kilograms or pounds accordingly.
