Results
Gross Deck Capacity
225 lb/ft²
Net Capacity (minus plate weight)214.8 lb/ft²
Capacity (metric)10.77 kN/m²
Total Deck Capacity112,500 lbs
Total Capacity56.3 short tons
Plate Self-Weight10.21 lb/ft²
How to Use This Calculator
- Enter the deck area in square feet and the steel plate thickness in inches.
- Input frame spacing in feet, steel yield strength in psi, and desired safety factor.
- Review the gross deck capacity (lb/ft²) and net capacity after subtracting plate weight.
- Check total deck capacity in short tons for cargo planning.
- Increase plate thickness or reduce frame spacing if the capacity is insufficient for your use.
