Fasteners for all five corrosion resistance classes
There are literally hundreds of different screws but they are not all of the same quality. Adverse conditions take their toll. A challenging climate, the huge forces experienced in buildings and special hygiene requirements – the products have to withstand all these extremes, and the selected material and quality must be just right. It’s a huge responsibility.
Especially in the building sector the use of high corrosion resistant fasteners is inevitable in complete Europe due to the general rules of assessment in the context of Eurocode 3 (DIN EN 1993-1-4:2015-10 – Annex A). Depending on the impact or pressure to the screw, nut or threaded bar, there is to choose one of the five corrosion resistance classes (CRC), which in return determine the necessary steel grade.
TOBSTEEL has specialized in high corrosion resistant fasteners of material 1.4571 (CRC III), 1.4462 (DUPLEX / CRC IV) and 1.4529 (HCR / CRC V) and supplies these directly from stock. Among them are DIN 125,127, 912, 931/933, 934, 976, 980, 985, 1587, 9021, 7991 (ISO 10642) and, including the standard materials A2(CRC II) and A4 (CRC III), another 25.000 DIN, standard and special parts altogether.
For each of the five corrosion resistance classes, TOBSTEEL supplies the right fixings from stock, whether for heliothermal plants, wind power stations, water treatment plants, swimming pool technology, tunnel construction, drainage systems for bridges or the ventilation technique, just to mention some of the application areas. The new premises built in 2014 provide a storage space of 9.000 m² for worldwide distribution.
No matter which corrosion resistance class is required for your next project, TOBSTEEL can supply the adequate fixings. The longtime know-how of the 60 employees and the realization of many large scale industry projects make it possible for the DIN-EN ISO 9001 certified company to offer also completesolutions for its customers’ projects. Thus the screw specialist supplies fixings for national and international construction projects in cooperation with welding operations of the highest execution class (EXC 4) and offers you future-oriented solutions especially for the following industry sectors:
