We start with the standard itself and always check more than one source, including makers' listings and spec sheets and the federal, state and local rules that apply.
We look at the real jobs and questions our customers bring us and add what's useful.
We sometimes use AI tools to help with research and drafts. Before a new guide goes up, a human on the core US Made Supply team reads it and checks it against its sources.
We revisit our guides regularly and update them when a standard, a rule or a product changes.
Some guides show products we sell. Buying one doesn't make a building compliant. Your local code official has the final say.
The “Updated” date changes only when a guide really changes.
