Hangzhou Zhongya Special Refractory Co., Ltd

Hangzhou Zhongya Special Refractory Co., Ltd. has been operating since 1986, giving it decades of experience in high-temperature industrial materials. Their key products — ceramic filters, die casting machines, ceramic fiber, graphite, and gas generation equipment — are used in heavy industries like steel and metallurgy, where reliability and heat resistance are critical. Being based in Hangzhou, China, places them near major manufacturing clusters, which helps with supply chain efficiency. However, none of their verification details — phone, work email, business documents, or account email — are confirmed. This lack of verification raises concerns about legitimacy and responsiveness, especially for buyers needing to validate supplier credentials before placing large orders. Buyers should request additional proof or contact through a verified channel to reduce risk when engaging with this supplier.
