Cookies are small files a website stores on your device. This page lists the cookies and similar technologies (such as local storage and tracking pixels) Steel Beam Calculator uses, who provides them, what they’re for and how long they last.
We only use cookies that aren’t strictly necessary if the law where you are allows it. In the UK, Switzerland, the European Economic Area, Gibraltar, Jersey, Guernsey and the Isle of Man we ask first, and we also ask first if we can’t tell where you are. The exception is our cookie-free statistics, which run in the UK and Switzerland without asking, and which you can turn off. Elsewhere, including the US, we tell you what we use and you can opt out.
If your browser sends a Global Privacy Control signal, we treat it as opting out of advertising, unless you’ve made a different choice in our cookie settings. It doesn’t turn off statistics or analytics.
When you’re signed in, advertising and session recording don’t run. The one exception is the page you see straight after subscribing, where the advertising tags run once to count the subscription.
You can change your choices at any time, using the link at the bottom of every page or this button. Each choice lasts 12 months. We ask again when it expires, or when we make a material change to the technologies we use. If you’re signed in, your choices are saved to your account and apply on all your devices and our sites, and we apply the strictest rules of the country you’re visiting from, the country set on your account and the country you signed up in.
You can also block or delete cookies in your browser’s settings, although the site won’t work properly without the strictly necessary ones. To opt out of advertising based on your browsing with many companies at once, visit youronlinechoices.eu or aboutads.info/choices.
Needed for the site to work and to keep it secure: keeping you signed in, protecting the site from attacks, remembering the country and design settings you chose, and remembering your cookie choices. These can't be turned off.

Some US state privacy laws give you the right to opt out of the “sale” or “sharing” of your personal information, and of targeted advertising. Those laws may treat the Advertising and Analytics cookies above as selling, sharing or targeted advertising. To opt out, use “Your Privacy Choices” and turn off Advertising and Analytics. A Global Privacy Control signal from your browser turns off Advertising, unless you’ve made a different choice in our cookie settings. Our sites don’t respond to the older “Do Not Track” setting. We don’t sell personal information for money.
Our privacy notice explains how we use personal information and your rights. Section 6 covers cookies, analytics and advertising.
We keep a record of each cookie choice for 2 years, so we can show we have respected it: the time, site, country, the rules that applied, what you chose, how you chose it and the version of this policy. The record doesn’t include your IP address.
Thank you, we really appreciate your help.
We use cookies and similar technologies for analytics and advertising. Under some US state laws, sharing information with our advertising partners counts as “selling” or “sharing” personal information. You can opt out at any time. Cookie policy
