Unjacketed Metal Conduits
Metal protective conduits from FLEXA without an outer coating are specialized cable protection systems intended for applications where mechanical resistance, flexibility, and durability in extreme conditions are key. The products in this category are made from profiled steel strip (stripwound), in single- or double-layer arrangements, with optional braiding from copper, steel, or tinned copper wire. These are solutions designed for sectors such as: machine construction, automation, heavy industry, energy, rail, and offshore.
FLEXA Metal Protective Conduits
What distinguishes FLEXA metal conduits (without coating)

Profiled strip constructions
Pipes with an S-profile or Agraff (double-folded) profile provide high resistance to compression and tension while maintaining flexibility, which facilitates installation and cable pulling.
Wide range of materials and braids
Variants with braiding from tinned copper, pure copper, or galvanized steel allow for the adaptation of the cover to specific requirements: electromagnetic shielding, chemical, or environmental protection.
Versions dedicated to special applications
Products such as FDW-VA or HG-CU-K are designed for applications in medical technology, sensor technology, or microwave transmission - with optimal braid coverage (>85%) and precisely selected braiding angles.
High environmental resistance without the need for coating
Pipes made of stainless steel or tinned copper do not require external insulation, yet they offer resistance to corrosion, atmospheric conditions, and vibrations.
Applications of metal conduits
- construction of machines and devices exposed to mechanical loads
- protection of cables in heavy, rail, offshore industries
- applications where flexibility is required while simultaneously shielding the signal (e.g., sensor technology, measurements)
- environments with high temperature, presence of oils, dust, vibrations
