STEEL PIPEBRIDGES
We are glad to announce, that the strong and durable prefabricated steel profiles have been added to the product assortment available in Hydroseal LLC. These quality steel plates are made in Germany and offer great variety of possibilities to construct pipe bridges with different shapes and dimensions. Corrugated steel pipes are assembled from corrugated steel plates, which are curved according to the pipe shape and will be connected to each other with bolts.

Bridges and culverts are essential parts in the system of roads and ways. The maintenance and construction of the efficiency of an economic domain and its environmental development require permanent care, renewal and reconstruction of roads and ways, as well as water courses. Construction and reconstruction of bridges and culverts are involved, whereby low-price solutions matched to the landscape are asked for. Increasing shortage in money of public budgets and keen competitive conditions of the economy force to search for economical, technical solutions, which at low cost-expense fulfill fast, long-lasting construction work with defined service value.
Flexible, embedded pipe made of structural steel parts (corrugated steel pipes) is a construction system, which for various problems fulfills these conditions perfectly:
• fast in preparation and execution of construction;
• economic, and with its high-quality corrosion protection long-lasting;
• nonsensitive compared to settlements;
• existing corrugated steel buildings can be extended by attaching new structural steel parts;
• dilapidated bridges or arch building can be restructured by inserting corrugated steel pipes without exerting influence of the above operating traffic.
On job-site, corrugated steel pipes are assembled from corrugated steel plates, which are curved according to the pipe shape. Usual pipe forms are circular profiles, pipe arches with various relationships of height/width, ellipses, circular arches and super-span arches.
Known fields of application are culverts and bridges in roads of all classes up to highways and service roads for heavy traffic. However, fields of application are by far not fully utilized. Using further construction elements, such as steel walls, bends, connecting pieces, entries, etc. pipes of various length can be constructed as well as storm water basins, back-water sewer, collecting pipes, escape tunnel or drainage pipe gallery in ground storage.
In addition to the standard cross-sections a variety of special profiles can be obtained with a variation of radii and angles of aperture to serve best the application purposes. Existing railway tracks and pipeline roads can be bridged with arches. The use of structural steel parts for the repair and reconstruction of old vault bridges and culverts with running traffic is most suitable. For these applications the profiles can also best be matched to the cross-section of the vault.
As there are more than 500 different steel profiles available on the market, then feel free to ask for additional and more precise information about the products by phone or e-mail!
The steel plates are easy to transport, since steel plates are in packs. Mounting has different possibilities. Manual comes with every pipe to indicate how the sheets should be located in the process of assembling.
