Zhoushan Hongxing Plastic Cement Co.,Ltd.

Zhoushan Hongxing Plastic Cement Co., Ltd. has been in business since 1993, giving them decades of experience in manufacturing manholes, manhole covers, and drains — a strong signal of reliability in a critical infrastructure product. Being based in Zhoushan, China, places them near major coastal ports and industrial zones, which helps with fast delivery and logistics for export buyers. However, none of their key verification details — work email, phone, documents, or account email — are confirmed, which raises concerns about identity and legitimacy. Buyers should request additional proof before placing large orders or sharing technical specifications. Without verified contact or documents, it's harder to trust their responsiveness or ability to handle complex supply chain needs. This lack of verification is common among older Chinese suppliers, but it's a key risk for international buyers seeking secure, traceable partners.
