Anhui Koyo Door&Window Engneering Co.,Ltd

Anhui Koyo Door&Window Engineering Co., Ltd. has been operating since 1992, giving it nearly three decades of experience in the door and window industry — a strong signal of stability and reliability. The company offers plastic profiles, other windows, and doors, which are in high demand in emerging markets where cost-effective, durable building materials are needed. Being based in China provides access to large-scale manufacturing and low production costs, making it a competitive option for international buyers. However, none of the key verification fields — work email, phone number, or business documents — are confirmed, which raises concerns about the company's legitimacy and ability to fulfill orders reliably. Buyers should request additional proof, such as a company registration or product samples, before placing large orders. Without verified contact or documents, it's hard to trust the accuracy of pricing or delivery timelines. This lack of verification is common among older Chinese suppliers who may not have adopted modern digital verification practices.
