Czech Republic-based steelmaker Liberty Ostrava has announced that it is expanding its product portfolio, launching a new product with higher added value. This year, the company will start supplying the market with threaded rods with double anti-corrosion protection designed to strengthen concrete structures. This year, it will start supplying the market with threaded rods with double anti-corrosion protection designed to strengthen concrete structures. In recent years, it has invested almost 80 million crowns in expanding the production of one of the most widely used concrete and anchoring systems in the world, which it produces as the only one in the Czech Republic.Steel threaded rods, rolled in the medium-rolling mill of the Ostrava steelworks since 2014, will be supplemented with two protective layers, plastic and cement, which will significantly extend their service life by up to 100 years, and thus the service life and safety of the buildings in which they are used. There is a high demand for them on the domestic and foreign markets, so Liberty Ostrava expects to be able to supply them to its clients worldwide in the amount of hundreds of tons per year.Part of the investment in the subsequent modifications of threaded rods in the Ostrava steelworks was the purchase of the necessary machinery, including a special cement mixer with grouting equipment, inclined platforms and grates. The threaded rods are first cut with a plastic sheath, and then cement is injected into the free space between the plastic and the rod.Threaded rods are used mainly in building structures, in the excavation of underground works and all geotechnical structures, ie in all mining works, tunnels or underground structures. However, they are also suitable for special uses, such as rock anchoring or rock mass switching. The bars are equipped with a special continuous thread along their entire length, which allows the nuts and other accessories to be screwed on, and thus the individual bars to be joined without the need for welding. Their installation is thus faster, which saves time and material on construction sites.
