Certification

In SIGNZONE, when each product is completed, a material inspection certificate and quality certificate provided by the material supplier of the product will be issued to the customer. We took the lead in establishing industry standards and independently passed the national technical standards certification. Among them, GB/T 19001-2016 ISO 9001:2015 International Quality Management System Certification, ISA member units, and “Guided Sign Board Testing Report" and “Advertising Lightbox Testing Report" and other certificates are issued, which are authorized by national authorities and certification by international marking agencies.
