From sketch to cutting file
Draw your plate with your finger or type the dimensions. MasMetal straightens it out and turns it into a DXF for laser, plasma or waterjet.
Plate → DXF
Rectangle, disc or flange, with holes, slots, rounded corners and chamfers.
Scriber
Draw with your finger. Grid, snapping, auto-straighten and CAD edits.
Request a price
Email the DXF to your own cutting shop, or get an online price from 247TailorSteel or OrderOn.
Numbers you can trust
If you buy steel on a number, it has to be right. So MasMetal shows where every number comes from.
How this was calculated
Every calculator card shows the working, with your own numbers.
Standards
Section data per AISC, ASTM A6, EN 10365, EN 10056-1 and EN 10210/10219.
