DSWIN Co., Ltd. was founded in 2005 by DONGSUH Control Co., Ltd., its parent company, which was established in 1975.

Since our opening, we at DSWIN Co., Ltd. have committed ourselves to the consistent development and production of customer-centered new products through the constant research on and development of PVC-only rollers and handle and system window hardware, thus leading to the creation of the country first zinc roller.

For decades, the locking device for windows and doors at home and abroad was dominated by the crescent type. Amid the current trend of further sophistication or scale-up in a wide range of buildings, however, such crescent-type products have been encroached upon by the rapid rise in the use of auto-rocks coupled with convenience and security.

Armed with the knowledge that the Korean consumers prefer user-oriented products with elegant designs for window and door products, we have succeeded in developing products that satisfy not only the aspect of quality but also the aspect of function, and with stylish designs that can make interiors pleasant and outstanding.
