Halogen-free corrugated pipe

Halogen-Free Corrugated Conduit – Flexible Cable Protection with Superior Fire Safety for Professional Installations

Discover our high-quality halogen-free corrugated conduit – the professional solution for protecting and organizing electrical cables in demanding installations. Made from premium halogen-free polymer, this flexible conduit provides excellent mechanical protection while ensuring maximum safety: it produces minimal smoke and no toxic or corrosive halogen gases in the event of a fire.

Ideal for electrical contractors, construction companies, renovation firms, industrial facilities, research centers, and van conversions, our LSZH (Low Smoke Zero Halogen) corrugated tubing meets strict international standards including EN 61386-22 and offers reliable performance in new builds, retrofits, and specialized applications.

Key Benefits of Halogen-Free Corrugated Conduit

Compared to standard PVC conduits, halogen-free versions significantly improve fire safety, reduce corrosion risks to sensitive equipment, and support modern building regulations that demand low-smoke, non-toxic materials.

• 100% halogen-free – no toxic or corrosive gases released during combustion
• Low smoke density for better visibility and safer evacuation
• Flame-retardant and self-extinguishing properties
• Wide temperature range: -25 °C to +90 °C
• High mechanical strength (320 N compression resistance)
• Excellent flexibility for easy routing in tight spaces
• Smooth inner surface for effortless cable pulling and future upgrades

Applications of Halogen-Free Corrugated Conduit

This versatile conduit protects cables from mechanical damage, moisture, vibration, and fire risks across a wide range of professional environments.

New Construction and Building Projects

Perfect for concealed installations in walls, ceilings, floors, and concrete. It ensures compliant, organized cable routing in residential, commercial, and public buildings.

Renovation and Retrofit Projects

Its high flexibility makes it ideal for upgrading existing electrical systems with minimal disruption – excellent for older buildings and modernization work.

Industrial and Commercial Facilities

Provides robust protection in factories, warehouses, and machine installations against vibration, dust, and mechanical stress while meeting strict safety requirements.

Research Centers, Laboratories, and Data-Sensitive Environments

In labs, universities, and research facilities, it prevents corrosive emissions that could damage sensitive electronics, measurement equipment, or data infrastructure.

Van Conversion and Vehicle Applications

Widely used in campervan builds, commercial vehicle conversions, and mobile setups due to its vibration resistance, temperature tolerance, and flexibility during movement.

Electrical Contractors and Service Companies

Professional electricians appreciate the fast installation, long-term reliability, and compliance with current fire safety standards for power, data, and telecommunications cabling.

Technical Specifications Overview

All sizes are CE-marked, comply with EN 61386-1 / EN 61386-23, and are tested for flame retardancy and halogen-free performance.

Frequently Asked Questions (FAQ)

What does “halogen-free” mean for corrugated conduit and why does it matter?

Halogen-free (also called LSZH or Low Smoke Zero Halogen) means the material contains no chlorine, bromine, or other halogens. In a fire, it releases far less smoke and no corrosive or toxic gases, protecting people, the environment, and sensitive equipment – especially critical in public buildings, data centers, and industrial settings.

Where is halogen-free corrugated conduit typically used?

It is suitable for concealed, surface, concrete, and hollow-wall installations. Common sectors include construction, renovation, industrial plants, laboratories, research centers, and vehicle conversions (e.g., campervans).

Does it meet current fire safety and installation standards?

Yes. It complies with EN 61386-22 for flexible conduits, DIN VDE V 0604-2-100 for halogen-free properties, and the Low Voltage Directive (CE marking). It is flame-retardant and self-extinguishing.

Is halogen-free conduit suitable for concrete embedding?

Absolutely. With its 320 N compression strength and robust corrugated design, it withstands the mechanical loads of being cast into concrete or screed while providing long-term cable protection.

How does it compare to standard PVC corrugated conduit?

Unlike PVC, halogen-free conduit does not produce corrosive gases that can damage electronics or building materials. It also features significantly lower smoke generation, improving safety during fire incidents and reducing secondary damage.

Can halogen-free corrugated conduit be used in van conversions?

Yes. Its flexibility, vibration resistance, and wide temperature tolerance make it an excellent choice for protecting wiring in campers, commercial vehicles, and mobile installations.

How easy is it to install and pull cables through?

Very easy. The corrugated structure allows tight bending, while the smooth inner surface enables fast cable insertion or future replacements using draw wire or lubricant.

Is it suitable for industrial and laboratory environments?

Yes. In industrial settings it resists mechanical stress and vibration; in laboratories and research facilities it minimizes risks to sensitive equipment by eliminating corrosive emissions.

Which size should I choose?

Selection depends on the number and diameter of cables. Use the table above as a guide: M20 is the most common for standard work, while M25/M32 suit larger bundles or heavier-duty applications.
