Rigid tube systems and their applications

  1. Electrogalvanized rigid tube system:

This system, designed to meet the requirements of ITC-BT-28 and ITC-BT-29, emerges as the ideal choice in installations with possible mechanical impacts or risk of explosion. Its application can occur in public places, automotive workshops, open-air or underground parking lots, as well as in the mechanical transformation industry. Its protection level (5557 according to IEC 61386) makes it the preferred option for safeguarding electric vehicle charging stations, in accordance with the low voltage technical instruction ITC-BT-52.

With a protection degree of IP 54, internal and external corrosion resistance of grade 2 out of 4 according to IEC 61386, and an electrical conductivity of less than 0.05 Ohm/m, this system is positioned as a benchmark in terms of safety and durability. .

  1. Hot dip galvanized rigid pipe system:

Similar to electrogalvanizing, this rigid tube system It maintains its fundamental characteristics but significantly increases corrosion resistance, reaching grade 4 according to IEC 61386 (very high protection). Its application is indicated in accordance with ITC-BT-30 and 31, providing a robust and durable solution.

  1. Stainless rigid tube system:

For those environments that demand exceptional corrosion resistance, the rigid tube system Stainless steel is presented as an outstanding option. It meets food industry standards and maintains outstanding mechanical resistance. Suitable for mounting according to ITC-BT-30 and 31, this system represents a high-end solution.


  1. PVC rigid pipe system:

Designed for indoor use in places with low mechanical liability, such as public places, schools, hospitals and residential buildings, PVC pipe offers corrosion resistance and does not spread flame. Its insulating nature makes it valid for installations that must comply with the requirements of ITC-BT-28 and ITC-BT-29.

  1. LH rigid tube system:

This system shares characteristics with PVC pipe, slightly improving mechanical resistance and manufactured with halogen-free materials. It stands out for drastically reducing the generation of harmful smoke in the event of a fire, positioning it as a safe and environmentally friendly choice.


The selection of rigid tube system Suitable depends on the specific characteristics of the environment and the protection needs of the interior wiring, being essential to consider the corresponding regulations and standards to guarantee safety and efficiency in each application.
