This is the place where we store the components for the doors. It is at this point the quality control starts its systematic checkup.
We strictly adhere to the norms for storage of materials and components. Warehouses of Steel Line are heated, which is allows us to control and establish necessary temperature and relative humidity.
In the production, we use a cold-rolled steel sheets, which provides high strength and durability of the door. From dry warehouse steel billets enter the production shop and undergo gentle anti-corrosion treatment and painting. That minimizes the interaction of steel with the negative environmental factors.
Steel Line uses the best locking system from the world's best manufacturers. Their experience is supported by hundreds of patents and quality certificates. It confirms the motto of the Steel Line factory: the best components - the best doors.
