Terms & Disclaimer

By using MGP10 Span Tables you agree to these terms. Please read them carefully — they matter especially because this site concerns structural building work. Last updated 2026-06-02.

Educational information only — not engineering advice

All content, guides and the Span Spec Builder are provided for general educational and informational purposes only. They are not engineering advice, structural design, certification, or a substitute for the official standards or a qualified professional. We do not publish allowable spans and the Spec Builder does not output one; it only assembles parameters for you to look up.

You must verify everything independently

Allowable spans and member sizes must be determined from the current AS 1684 span tables (or a manufacturer's current published tables) for your exact situation, and your design must be confirmed by a qualified structural engineer or building certifier. Wind classification, load widths and load cases must be properly assessed for your site. Do not build from this website alone.

Regulatory compliance is your responsibility

Structural building work is regulated. It generally must comply with the National Construction Code and the relevant Australian Standards, and may require design, approval and certification by competent persons. Ensuring your project meets all applicable laws, codes and approvals is your responsibility.

No warranty & limitation of liability

The site is provided "as is" without warranties of any kind, express or implied, including accuracy, completeness or fitness for a particular purpose. To the fullest extent permitted by law, we accept no liability for any loss, damage, injury or cost arising from use of — or reliance on — this site, its guides, the Spec Builder, or any product purchased through our links. You use the site entirely at your own risk.

Affiliate links & advertising

The site contains advertising and Amazon affiliate links; we may earn commissions from qualifying purchases at no extra cost to you. See the affiliate disclosure.

Intellectual property & trademarks

Grade designations and standard names referenced here belong to their respective owners; this is an independent guide and is not affiliated with or endorsed by any standards body or manufacturer.
