An History Built by People
STET celebrates 65 years of a history built on people, knowledge, and commitment to the future.
Throughout 2026, we celebrate a solid track record marked by constant innovation, trust built over time, and a clear vision of what lies ahead.
As a trusted partner of the premium brands it represents in Portugal—Caterpillar®, Sandvik, Pronar, and Magni—STET continues to turn challenges into opportunities and ideas into concrete solutions, reinforcing its role as a market leader.
A history marked by innovation and growth
For six decades, STET has accompanied the growth of the industries in which it operates, facing market challenges with determination, adaptability, and innovation. Continuous investment in technology, infrastructure, and team development ensures not only service excellence but also that each project is a story of trust, excellence, and success.
Business portfolio expansion
STET began its history exclusively representing Caterpillar® in Portugal and Cape Verde. Over time, it grew and diversified its portfolio, incorporating prestigious brands such as Sandvik and Pronar. More recently, in 2025, it also began representing Magni, while maintaining the same commitment to quality, premium service, and the trust that customers place in the company. This evolution reflects not only the expansion of the business, but also STET’s ability to keep pace with market needs and offer complete, reliable, and excellent solutions.
Skills development
STET’s growth has been accompanied by significant investment in technical skills. The company now has a large team of specialized technicians who are able to provide highly qualified after-sales service, ensuring complete support from installation to ongoing maintenance.
Skills development is a strategic priority, ensuring operational excellence, reliability, and confidence in every project.
People and partnerships at the heart of the story
More than just a milestone, STET’s 65th anniversary celebrates the contribution of the people who built its history and the partnerships established over time. This anniversary is an opportunity to recognize the work of the teams, reinforce institutional values, and project the strategic vision that will guide the company toward future challenges.

Extension and remodeling of facilities
In recent years, STET has strengthened its national presence by opening new facilities in Leiria, Madeira, and most recently in Beja, allowing it to be closer to its customers and offer an even faster and more efficient service. These new infrastructures reflect the company’s growth and commitment to quality, modernity, and specialized service.
65th anniversary commemorative logo
To celebrate this historic milestone, STET has launched a special extension of its logo, highlighting its 65 years of history.
The design reflects the company’s trajectory, combining solidity, innovation, and vision for the future, and reinforces the values that have always guided STET: trust, partnership, excellence, and commitment to customers and communities.
Looking toward the future
With concrete action and ambition, STET continues to create value for Customers, Partners, and Communities, maintaining its firm commitment to innovation, excellence, and progress. The celebration of 65 years is, therefore, a moment of reflection on the past, action in the present, and ambition for the future.
