Manufacturers since 1957

Rubber modeling company

In 1957, Antonio Riesco & JM Alonso created the company Rials SA for the manufacturing of rubber profiles and frames vulcanized by steam. It started out as a small business which answered to very small and specific demands of many sectors and its success brought the company to create annex companies only a few years later.

In 1972 NEOTEX SA is created for the manufacturing of rubber profiles vulcanized by UHF and LCM. A few years later, in 1974, RUBALCA S.A. is created for the manufacturing of rubber raw material and a laboratory is created for the control and investigation of new compounds.

In 2015 RIALS SA turns into RIALS SL, maintaining the same human and productive resources. With more than 60 years of experience, our company has a strong commercial network in Europe and the rest of the world and has assumed a leading position  in the development of products with high added value.

Thanks to its history and extensive experience, RIALS S.L. is nowadays a specialised company in the manufacture of rubber profiles. In order to meet the customers needs , our company makes a selective analysis of the most adequate material, evaluates all the requirements, functionalities and applications of the final product and the capacity to produce the required units with high precision.
