Sheet Metal Tools & Calculators
Every calculator, chart and checklist our quoting engineers use — free, no signup, no email wall. Pick a tool, run your numbers, and send the drawing when you're ready.
Engineering toolsSheet Metal Weight Calculator
Weight per piece and per batch from L × W × t, with real alloy densities.
Sheet Metal Gauge to mm Chart
Steel (MSG) and aluminium (B&S) gauge dimensions, and why we quote in mm.
Bend Allowance Calculator
The neutral-axis length through a bend, from thickness, radius, angle and K-factor.
Sheet Metal Cost Calculator
Where a part’s cost actually sits — material, cutting, forming, finishing and setup.
Sheet Metal DFM Checklist
The 24 checks we run on a drawing before we quote it, grouped and explained.
Sheet Metal RFQ Checklist
The 12 items that make an RFQ quotable in one round, with the reason each matters.
Sheet Metal Supplier Audit Checklist
13 remote-verifiable checks for a sheet metal supplier, in four passes.
Press Brake Tonnage Calculator
Bending force in kN and tons from thickness, material and bend length, with a 20% margin.
K-Factor Calculator (Reverse)
Reverse a K-factor from a real bend: outside dimensions and flat length in, K out.
Hole-to-Bend Distance Calculator
Minimum hole-to-bend and hole-to-edge clearances from thickness and inside radius.
