One line of HTML. Your visitors get a handy rebar weight & bar-count tool, you get a more useful page — free forever, no signup.
This is exactly what your visitors will see. Try it:
Paste this where you want the calculator to appear on your page:
<iframe src="https://getsteelcut.com/embed/widget.html" width="100%" height="480" style="border:1px solid #d9e1e9;border-radius:12px;max-width:420px" loading="lazy" title="SteelCut rebar weight calculator"></iframe>✓ Copied!
That's it — no JavaScript, no API keys, works on any website builder (WordPress, Wix, plain HTML).
Adjust the size, or pre-fill values for your customers with URL parameters:
| Option | How | Example |
|---|---|---|
| Width / height | Change the width, height and max-width in the snippet. Minimum recommended: 300px wide, 480px tall. | height="520" |
| Preset diameter | Append ?d=16 to the widget URL (6–40 mm). | widget.html?d=16 |
| Preset length & pieces | Append &len=6&n=50. | widget.html?d=16&len=6&n=50 |
The widget is fully responsive and works on phones, tablets and desktops.
No fees, no trial, no signup for you or your visitors. It just works.
Under 15 KB, lazy-loads, zero dependencies. Won't slow down your page.
An interactive tool keeps people on your page longer — and the "Powered by SteelCut" link sends curious ones to the full free optimizer.
Please don't — that link is what keeps the widget free. It also gives your visitors one click to the full cutting optimizer.
No. Everything runs in the visitor's browser; nothing is sent anywhere.
