New: Stainless steel DAVEX beams

ThyssenKrupp Steel : 25 June, 2006  (New Product)
Having successfully launched its carbon steel DAVEX profiles and established a Europe-wide distribution network, Gelsenkirchen/Germany-based ThyssenKrupp DAVEX GmbH is now introducing a new product: DAVEX profiles of stainless steel.
Having successfully launched its carbon steel DAVEX profiles and established a Europe-wide distribution network, Gelsenkirchen/Germany-based ThyssenKrupp DAVEX GmbH is now introducing a new product: DAVEX profiles of stainless steel.

With its high-quality, pickled stainless steel surface, this new product doesn't just look good, it also offers genuine cost benefits: as the geometry of the beams, e.g. the thickness of the web relative to the flange, can be designed more flexibly than with conventional profiles, the DAVEX beams can be matched more accurately to actual loads in use. While offering the same strength, the profiles are lighter and, as less material is needed, less expensive than comparable products produced by hot forming or laser welding.

These material and cost benefits are the result of an innovative production technology. The beams are manufactured by the so-called roll joining process, in which a special tool first rolls a groove into the flange material. In parallel with this, the edges of the web material are contoured and inserted in the flange groove. Subsequently a locking groove is rolled into the flanges on either side of the web, causing material to flow into the contours on the web edges. The result is a firm friction/positive joint produced from slit strip in a continuous, high-speed process, with the web considerably thinner in relation to the flange than on conventional profiles. And there are further advantages when it comes to appearance: DAVEX beams have sharp edges, making them look lighter and finer than hot-rolled or laser-welded profiles.

The new stainless steel profiles from ThyssenKrupp DAVEX are available as standard in six different geometries with flange edges in slit strip quality. The beams are supplied in standard lengths of six meters and in shorter lengths of three, four and five meters, depending on availability. Web and flange are made from stainless steel 1.4301. The flexibility of the roll joining process also allows special geometries and the use of other materials or material combinations.
