Thank you for visiting the Cheong O website.
Based on the idea of connecting people to space, premium windows for many years While researching and developing only the quality, we can provide efficient and economical windows for customer needs I'm working hard to make it.
Our product has been reborn as an aluminum system window that overcomes the weaknesses of materials with high thermal conductivity and has the greatest strength. We are not only satisfied with insulation, airtightness, watertightness, condensation, and durability, but we will continue research and development to maintain these performances.
The windowpanes are not just windowpanes, except for glass. We will try to satisfy our customers with a higher quality of the product by allowing them to choose the aluminum system window and glass together.
Thank you.
