Our editorial purpose
Granite China is an independent English-language reference created to turn a complex subject into practical, checkable decisions.
How we work
We prioritize primary sources, standards owners, government publications, universities and established technical references. Each guide distinguishes sourced facts from editorial interpretation and avoids claims that cannot be supported.
