• Steel Door

Since its establishment, we have accumulated knowledge as pioneers in large doors and have developed a construction method for large opening doors that is safe and leads to cost reductions. In conventional construction methods, the products themselves become extremely heavy, making transportation and installation very dangerous. However, with our method, only the cart part, which is the heart of the door, is manufactured in the factory, and the rest is brought to the site in parts. The assembly of the parts above the cart is done on-site. With the above method: 1. The elimination of heavy lifting significantly improves the safety of workers. 2. The absence of heavy lifting allows for a reduction in the heavy machinery used, leading to substantial cost savings compared to conventional methods. 3. Unlike traditional methods, work is performed at the door installation location, eliminating the need for a workspace for ground assembly. (However, a temporary storage area for the parts is required.) 4. The elimination of ground assembly reduces the impact of weather on the work, ensuring it does not affect the overall construction schedule. This method is effective for doors that exceed 10 meters in height or doors that are wider than vehicle sizes. Registered with NETIS!
