Cost steelwork with your own rates
Stek-Calc costs a complete steelwork job: plates and profiles in, a substantiated quote out. You see per line where the money sits — material, machining, coating, assembly and overheads — instead of one number at the bottom of a spreadsheet.
Included in Workshop Pro and Business. On Workshop you add it to your plan.
What you do with it
Plates and profiles in one calculation
Lines for plates (length, width, thickness) and profiles (series and length, or your own kg/m). Weight follows automatically; no weight table to look things up in.
Your own rates, not ours
Material price per kilo, hourly rates for production, assembly, crane and engineering, coating per m² and your overheads. The tool tells you while you are still on the example rates.
See where the money sits
Per line and for the whole job: material, machining, coating, assembly, overhead and margin. So you know where you can come down without going under.
A quote comes out
A quote PDF with your own logo and details, a fuller calculation PDF for yourself, and a CSV for the bookkeeping. Revisions are kept, so you can go back to what you offered before.
What a calculation looks like

Frequently asked questions
Does Stek-Calc use real steel prices?
No, deliberately. You enter your own purchase prices and hourly rates. Example rates are there to start with, and the tool warns you while you are still using them.
Can I pull a calculation from an existing project?
Yes. Plates from a Stek-Plaat project come in as lines, and a Tekla material list can be read in as a PDF.
Can I send the quote in my own house style?
Your logo and company details go on the quote PDF. You set those once in your account.
What happens if I change a calculation after sending it?
You lock the sent version as a revision and continue on a new number. The original is kept.
Can I buy Stek-Calc on its own?
Not without a plan. It is included in Workshop Pro and Business, and on Workshop you add it to your running subscription.
