Type 7111, 7511, 7631
Longitudinally welded with wide inside corrugation. The wide range of dimensions of round cavity pipes covers diameters from 21 mm to 1,500 mm. A general profile height from minimum 2.5 mm to 8.00 mm allows for the use of these pipes in anchor engineering. The continuous inside and outside profile allows for force-locking anchoring, but also for the construction of cavities... more

Type 7531
The cavity pipe with square or rectangular cross section is mainly used in prefabricated concrete engineering. The wide range of dimensions and cross-sections allow for optimum application. Mainly with only limited concrete cover of elements or whenever passages or anchor points are specified, the square cavity pipe provides the required flexibility with the additional benefit... more

Type 7512
The so-called bendable pipe demonstrates its advantages when being used with complex parts in walls, ceiling or also in bottom plates with backfill openings for the starter bars and their subsequent backfilling or press fitting. A characteristic feature of this pipe is its profile, which allows for a relatively easy bending of a 90° bend without buckling. This means that the... more
