Design & performances


Our whole flood defence program is mainly made of selected marine aluminium alloys that are guaranteed corrosion free even in the worst aggressive environment. Furthermore, the items are manufactured either with hot extruded profiles or laminated sheet and they all get additional heat treatment for hardening purposes. These profiles or sheets show excellent weld ability characteristic.

Why aluminium alloy:

Current modern aluminium metallurgy provides a great variety of profiles, in size and shape, suitable to withstand various stress or engineering requirements, and have with excellent chemical resistance to corrosion as well. Its many uses include the aeronautics and motor industry. Also the waste water industry has been using aluminium extensively for many years now. 


Aluminium alloys are obtained from about 97% pure aluminium to which one add several components, in specific measures, controlled   by international standards. Principal among these components are magnesium (Mg) silicon (Si) manganese (Mn) and copper (Cu).

BERGTEC-MSU, is   supported   by its long association with their main aluminium supplier, based in Switzerland, manufacturing with the highest quality in terms of accuracy and performance. Furthermore the Swiss extruder is a 100% environment friendly operational company with more than 80% of its extrusion waste   recycled so reducing substantially its "carbon footprint".

Your warranty:  Flood defence items are designed and manufactured according to European and ISO standards and they are manufactured with maximum deflection under load (to guarantee excellent water tightness).

In addition, we have a track record in design-and-build, since 1970, and expertise in providing a complete engineering service based on our own, indoor technical department composed by a team of engineers working with latest 3D/ CAD software.
