Safe grain mills thanks to SP gratings

One of the biggest manufacturers of wheat flour in the southeast of Poland whose milling traditions go back many centuries, is moving its activities from Cracow to Niepołomice. A production facility was built for the Polish grain factory (Polskie Zakłady Zbożowe) on a 4 ha site in the Special Economic Zone. The project consisted in building a mill with offices and technical facilities, access route, parking and technical infrastructure. Everything in this milling complex, from the receipt of the grains, the silos and the mill, to the packaging of the final product is brand new. Research activities and technical analysis services are also planned to take place at this location.

The first phase of the investment consisted of building a new production line with a daily yield of 400 tons, and moving one of the existing production lines with a daily yield of 200 tons from Cracow. The factory's daily yield is approximately 600 tons. Staco Polska also played a role in this big project. Staco Polska received an order to supply over 1,000 m2 of SP welded gratings and proved to be the right partner to deliver gratings for the whole project. Staco Polska received the order for the SP gratings because of their durability, stability and load-bearing capacity. The drawn and twisted crossbars provide excellent slip resistance on the technical platforms in the mills, the silos, and the production buildings and warehouses. Welded gratings from Staco are also used as canal covers. Staco Polska also delivered stair treads and a platform to the storage building for pallets.

The current location will enable Polskie Zakłady Zbożowe to continue developing. At the old location, logistics prevented the expansion of the wheat and flour silos. Because the company has a long-standing connection with Cracow, it was decided to keep one production line with a daily yield of 300 tons. Staco Polska is convinced that the sturdy Staco gratings in the new milling complex will contribute to the production of flour in the coming decades.
