Corrugated steel structure
Corrugated steel structures (also corrugated steel tubes , steel tube passages , spiral tubes ) are structures with up to about 30 m span, the load capacity on a composite action between corrugated steel based and surrounding bedding material. Areas of application are mainly underpasses for flowing water , pedestrians and road traffic under road and railway embankments.
Corrugated steel structures are regulated in Germany in ZTV-ING Part 9 "Structures", Section 4 "Corrugated steel structures". There they are defined as follows: Corrugated steel structures "are flexible, steel structures embedded in the ground. They are only screwed from corrugated sheet steel elements that are corrosion-protected at the manufacturer's site to form various cross-sections in the longitudinal and circumferential direction and then embedded in compactable soil The load-bearing behavior of the structures is that they deform under load until a support line running in the building wall has approximately formed on the circumference of the structure from the loads from the soil and traffic and the restoring forces resulting from the deformation.

history
,_1896.jpg)
One of the first confirmed production of spiral tubing was in Crawfordsville, USA, in 1896 . The corrugated steel tubes manufactured at that time are in principle comparable to today's spiral tubes. In the mid-1950s, ARMCO ( American Rolling Mill Company ) brought this product family to Europe. Founded in Middletown, USA in 1899, ARMCO developed the principle of screwing curved corrugated steel plates together to form profiles. Even today, multi-plate systems under the name ARMCO-Culverts are common in technical parlance. ARMCO itself discontinued the product branch in the early 1990s due to restructuring measures in Europe.
One of the first European producers in Germany was Thyssen , which together with ARMCO Inc. founded a production site in Dinslaken in 1956 and introduced this technology in Germany. This production site still exists today (now: Hamco Dinslaken Bausysteme GmbH). In Austria, voestalpine, at that time still VÖEST Linz, started production of multi-panel systems in Linz in 1961.
Over the past fifteen years, the technical possibilities of corrugated steel structures have been steadily expanded through intensive research and development , which is why this product is now widely used in international infrastructure construction.
