Civil engineering
Under heavy loads such as stretching or crushing, extruded plastic profiles are in their element. For civil engineering, Heller Kunststoffe manufactures plug-in, joint and sealing profiles for expansion joints, edging profiles for roof ventilation and tubes in special shapes such as oval.
Five profiles, one joint
For expansion joints and adjacent construction tasks we supply coordinated profiles. All five come from real customer projects.
-
01
Plug-in profile for expansion joints
Fills the joint and keeps space free for the movement of the structure.
-
02
Joint profile for expansion joints
Closes the joint to the outside and stays permanently flexible.
-
03
Sealing profile for expansion joints
Seals against water and dirt, designed for permanent deformation.
-
04
Edging profile for roof ventilation
Fabricated edging profile for guided ventilation at the roof edge.
-
05
Oval tube
Hollow profile in a special shape: when round does not fit, we extrude oval.
From joint dimension to tool
Your joint has a dimension; our wire EDM machines turn it into the tool. Samples before series included.
To toolmakingFAQ: Civil engineering profiles
Which profiles does Heller manufacture for civil engineering?
Documented applications are plug-in, joint and sealing profiles for expansion joints, edging profiles for roof ventilation and oval tubes. Further construction profiles are made to your drawing.
What do expansion joint profiles have to achieve?
Expansion joints work: components expand, contract and shift against each other. The profiles must follow that movement permanently without tearing or migrating out of the joint.
Are special cross-sections like oval tubes possible?
Yes. Besides open profiles we extrude hollow sections and tubes in special shapes, each with a dedicated tool from our in-house toolmaking.
In which lengths are profiles delivered?
As fixed lengths, with mitre cuts on request, or as rolls, depending on how you process on site or in the factory.
