1. About the Service
SectionTables.com is a free online collection of reference tables, calculators and short technical notes for practising structural engineers and students. By using the site you accept the terms below.
2. A note on translations
English and Polish are written and maintained by the author. The other languages (German, Czech, French, Italian, Spanish) are machine-translated. The translations are reviewed before publishing, but may still contain awkward phrasing or small inaccuracies in technical terminology. If you spot something off, please let me know through the Contact page — corrections go out quickly.
3. Accuracy and use in real projects
The content is provided as-is, without warranty of any kind. Numerical results are an aid to engineering judgement, not a substitute for it — a qualified engineer should verify any result before it is used in a real project. If you spot a mistake, the Contact page is the fastest way to let me know.
4. Standards
Tables and calculators follow the Eurocodes (EN 1992, EN 1993 and related parts). The Eurocodes themselves are copyrighted by CEN and its national members, so this site publishes only derived values and formulae — never the standards’ text or tables verbatim. For a final design, always consult the current official version of the relevant standard.
5. Copyright
All original content on the site — wording, layout, icons, generated tables, source code, images — is the property of the author. You are welcome to view, print and reference pages for your own engineering work, study or reports. Please do not republish or redistribute larger parts of the site without written permission.
6. No accounts, no tracking
The site does not require an account and does not use third-party analytics, advertising or social-media trackers. A short-lived signed token is issued in the browser to keep the data tables usable for humans and reasonable for the server; it is not a cookie and carries no personal information.
7. How the language is chosen on your first visit
On your first visit, the site opens in the language that best matches you. It looks first at a previously saved "lang" cookie, then at your browser’s Accept-Language header, and finally at the country that the hosting provider (Cloudflare) associates with your IP address for that single request. If none of these points to a supported language, the site falls back to English. The IP address is used only in-flight for this country lookup and is not stored. Once you pick a language yourself (see the next section), your saved choice takes precedence over everything above.
8. Preferences
When you pick a language from the switcher, your choice is saved in a small functional cookie (named "lang", valid for one year) and mirrored in your browser’s local storage, so the site opens in that language next time. The dark / light theme choice is stored in local storage only. These preferences contain just the selected value and can be cleared at any time from your browser settings. Because they are saved only in response to your own click, no separate consent banner is shown.
9. Contact form
If you send a message through the Contact form, the message itself — together with your optional name and email, the page you wrote from, the selected language, and your IP and user-agent — is kept in a simple log so that I can reply and keep spam out. Messages are kept for up to 12 months after my last reply and then deleted on a rolling basis. You can ask me to delete your message earlier at any time — just write from the same email or reference the earlier message. Nothing else is done with this data and it is not shared with anyone.
10. What this site does not do
For clarity: the site does not use Google Analytics or any other third-party analytics, advertising networks, retargeting pixels or social-media trackers. It will never send you marketing or promotional email. Your visits are not profiled and your data is not sold, shared or licensed to anyone. External sites linked from articles have their own policies, which I do not control.
11. Changes
These terms and the site itself may be updated from time to time. Continued use after a change means you accept the updated version.
