Hangzhou Singer Building Materials Co.,Ltd

Hangzhou Singer Building Materials Co., Ltd. operates in a sector where material quality and consistency are critical for construction projects. Their product range of bitumen, fiberglass, and roof tiles covers key building materials used in both residential and commercial construction across Asia and beyond. Founded in 2006, the company has over 18 years of experience, which suggests a stable presence in the market. However, the lack of verification on work email, phone, documents, and account email raises concerns about identity and legitimacy — a common risk when dealing with suppliers from China. Buyers should request additional proof, such as a business license or product samples, before placing large orders. Without verified contact details, it's difficult to confirm responsiveness or track communication. This makes due diligence essential before any trade engagement.
