Moving to Jerez
We relocated the factory to Jerez de la Frontera, moving into rented premises at the Polígono El Portal industrial estate — a strategic step that opened new opportunities and brought us closer to our clients.

Our own premises
We purchased our own unit at Jerez's Parque Empresarial: 1,000 m² of factory floor on a 1,500 m² plot — a milestone that cemented the company's foundations and gave us the space to grow.
