Thesla was established in 1996 for the production of prewired ribbed tubes.

The production process of prewired tubes was initially manual. The tubes were purchased, and the combinations of cables or wires were pulled in with mechanical assistance. Very quickly Thesla decided to take control of the extrusion process. This production process involves producing the tube around the wires or cables. The final product is then wrapped in commercial packaging.

Over the years, the production site was enlarged up to 4 times and new and more performing machines were gradually installed to increase capacity. Thesla grew organically through the years and entered the international market.

To this day, Thesla remains committed to a combination of people and technology.
