Hot Extrusion TechnologyAlex2022-03-04T16:10:29+01:00
During hot extrusion a round steel billet is pre-heated and, after leaving the furnace, is pushed through a forming die into a profile bar using a ram with an extrusion force of 2,200 tons. Hot extrusion can be used to make complex profile shapes even using metals which are difficult to form. In addition, small lot sizes can be produced economically.
“Form is not the aim of our work, it is the result.”

In planning façades, architects not only impose ever greater demands on the flexible adaptation of the materials, but also on individual desires for design. Within the realm of the production possibilities, special steel profiles from MONTANSTAHL can fulfil almost all the requirements for freedom of design, construction physics and architecture as part of an overall ecological concept.
We develop our special profiles in close co-operation with our customers offering above all solutions for unique design and functional challenges.
Circumscribed circle for solid and hollow profiles up to 255 mm Ø
Inside diameters or diagonals for hollow profiles of at least 20 mm to a maximum of 160 mm
Minimum wall thickness: 4 mm
Up to c. 16,800 mm (depending on profile cross-section)
Weight per meter:
Up to maximum 110 kg/m
Hot extruded profiles offer the following benefits:
Seamless finish for solid and hollow profiles (homogenous grain structure and no danger of leakage), thus particularly suited for heated façades
Different material thicknesses within a profile cross-section (advantage: low construction depth with the same structural characteristics)
Integration of grooves to take seals
Surface smoothing by means of cold drawing
Economical production even for small batch sizes
MONTANSTAHL maintains a management system to ensure quality and environmental protection which is certified according to DIN EN 9001 and respectively DIN EN 14001 by an independent accredited certification body.
Material tests can be certified according to DIN EN 10 204.
The following tests can also be carried out, if required:
