Brand names and logo

“Double Building Materials”, “Double Building” and the Double logo are the brand names and logo of Double Building Materials Co.,Ltd. Do not use them in a way that suggests we make, supply, endorse or install for your business when we do not. Other names on this site, such as Google, Meta, Microsoft or standards bodies, belong to their owners.

Information on this site

Our guides, sizes and code references are general information to help you plan. Your project is made to the shop drawings you approve. Your local engineer, inspector or building authority decides whether a design meets local code, and we do not sign off code compliance. Colors and finishes can look different on screen than in real life, so ask for a sample if the finish matters.

Quotations and orders

Nothing on this website is an offer to sell at a set price. Every order is made to order and quoted for your project. Payment, lead time, delivery, installation and warranty terms are agreed in the written contract for each project.

Links to other sites

We link to other websites, such as YouTube, Google and standards bodies. We do not control them and are not responsible for their content.

Changes

We may update these terms. The date at the top shows the latest version.
