In terms of standardized installation, we have introduced an 8+15 step standard process for installation of water supply and heating system, in an effort to follow scientific standards instead of traditional experience and avoid deviations caused by subjective experience.

We adopt an 8+12 step acceptance system. After auditing and supervising the quality of water supply and heating system installation services and archiving relevant documents, we will issue a quality assurance certificate to our consumers. It allows consumers to enjoy the import quality while alleviating their concerns about after-sales guarantees for imported brands.
