The main application of high corrosion resistant materials in Europe is the construction, basing on the dimensional norms as per Eurocode 3 ( DIN EN 1993-1-4:2015-10 – Attachment A ). Starting from the impact and load on the screw, nut and bar there are five corrosion resistance classes (CRC) that determine which steel to use.

The company TOBSTEEL GmbH, based in Öhringen, south-German, can provide the right fixing for each one of the five corrosion resistance classes. Whether for solar-thermal systems, wind power stations, water treatment plants, swimming-pool technology, tunnel and bridge construction or ventilation systems and many other applications.

In close collaboration with the Informationsstelle Edelstahl Rostfrei (Information office for stainless steel) TOBSTEEL GmbH was involved in the procedure of the current approval Z-30.3-6 of 12th may 2017 of the German Institute for Structural Engineering (DIBt). Because of this, the company will be mentioned in the relative special print 862 as the specialist for high corrosion resistant fasteners .

In the new company building of 2014 there is a warehouse space of 9.000m², built for deliveries all over the world. TOBSTEEL GmbH store here fasteners in standard materials A2 (CRC II), A4 (CRC III) and 1.4571 (CRC III), but also in high corrosion resistant materials 1.4462 (DUPLEX / CRC IV ) and 1.4529 (HCR / CRC V ). Among them DIN 125, 127, 912, 931/933, 934, 976, 980, 985, 1587, 9021, 7991 (ISO 10642) as well as around 25.000 other standard and special items directly available on stock.

Independently from the resistance class you will need with your building project, the company will supply the right fixing. Thanks to a know-how of a team composed by 60 people and to several industrial building projects already realized, the company, DIN-EN ISO 9001 certified, can offer complete solutions to its customers. Also fixings for welding works are available, in the highest classes (EXC 4) for several construction projects, both national and international.
