The stainless steel raw materials used by the stainless steel cookware produced by Guanhua are all purchased from superior suppliers in China and Korea. We carry out strict quality control for each batch of stainless steel to ensure that the product delivered to our customers meets the requirements of the customers, thus continuously improving the degree of satisfaction.
The lab of Guanhua is equipped with a spectrum analyzer which can be used for raw material inspection. The inspection mainly includes XRF component analysis and mechanics property analysis (including yield strength, strength of extension, ductility, hardness etc.) of the steel coils.
For all of the materials, we strictly control the content of any hazardous substances, especially VOCs (volatile organic compounds) which are well defined in REACH, PAHs and some other related laws and regulations.
