Flexible, embedded pipe made of Hamco structural steel parts (corrugated steel pipes) is a construction system, which for various problems fulfils these conditions perfectly: fast in preparation and execution of construction, economic, and with its high-quality corrosion protection long-lasting.

On job-site, corrugated steel pipes or MultiPlate are assembled from corrugated steel plates, which are curved according to the pipe shape and may have plate thicknesses of 3 mm to 7 mm, by means of bolt connections. Usual pipe forms are circular profiles, pipe arches with various relationships of height/width, ellipses, circular arches and super-span arches. The Hamco MultiPlate programme includes optimized corrugations for different cases of application.

Known fields of application are culverts and bridges in roads of all classes up to highways and service roads for heavy traffic, for which the term corrugated steel pipe became standard not considering classification in to culverts and bridges according to span widths < 2 m and/or > 2 m. 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 gallary in ground storages.

The offered standard cross-sections are assimilated to various conditions of application:

flat pipe arch profiles for stream culverts and smaller river bridges underneath roads of all classes, railway lines and service roads

underpass profiles with a relationship of height/width of approx. 1 : 1,15 for crossing of bycicles, pedestrians and hikers, roads and service roads underneath roads and railways

small pipe arch profiles used as passages for amphibians and deer

constructive details such as bends, inlets, etc. can be accomplished without problems

Besides the applications described above in road and bridge building MultiPlate structures are also used in industry and agriculture. Structural steel parts are also used as discharge pipe for gravel, where material heights of up to 25 m can be reached, and silos for the storage of gravel, sand, crushed-rock, etc.. The structural details of discharge pipes can also provide for hopper inlet, change in slope, sump, fixation of wires or else. After years, the pipes can be disassembled problemfree and transferred ton other working fields.

Silos needing ordinary footing on ring foundations can be built up to a height of 12 m and a diametre of 16 m.
Manure tanks made of MultiPlate structural steel plates for the agriculture are circular tanks, which are placed on a steel concrete bottom and provided with a tight sealing band and special corrosion protection. These tanks are also suitable for fresh water tanks in industry.
