Surface Engineering at Scale
Interview with Michael Segnana, Commercial Director and Dirk Broekhoven, Technical Sales Manager of Alro NV
From protective coatings to highly specialized finishing processes, industrial surface treatment has become a decisive factor in modern manufacturing – particularly in the automotive sector. Alro NV, headquartered in Dilsen, Belgium, has evolved from a specialized provider into a key international player in this field. In conversation with Commercial Director Michael Segnana and Technical Sales Manager Dirk Broekhoven, we explore the company’s development, its global footprint, and the challenges shaping the future of industrial coatings.
Founded in the 1970s by Luc Thijs, Alro has developed from a small paint shop into an international coating partner with around 700 employees and a turnover of approximately EUR 100 million. The company achieves an export share of around 75 to 80%. Today, Gimv acts as the main shareholder. Alro operates from its headquarters in Dilsen, a second nearby site located around 1 km from the main plant, as well as its Genk facility, known as WCA Alro. As part of a strategic consolidation, earlier activities in Slovakia and a joint venture in China were discontinued. Over the years, the company has continuously developed from a regional provider into an internationally active partner for the automotive industry.
One-stop-shop coating with engineering depth
Alro’s core business combines cathodic electrocoating, wet painting and powder coating. In addition, the company has developed advanced solutions such as fire protection coatings for battery systems in response to growing e-mobility requirements and stricter European safety regulations. One example is a patented solution that significantly exceeds existing standards for thermal runaway protection. At the same time, Alro has expanded its KTL capacities with a second KTL line to meet increasing demand in e-mobility, particularly for coating battery trays and battery boxes. The company processes more than 100,000 components per day in over 1,000 colours. It operates as a one-stop shop covering pretreatment, masking, coating, demasking, and assembly as well as just-in-time and just-in-sequence delivery. For example, Alro supplies DAF on an hourly basis in exact production sequence. In addition, the company delivers fully assembled modules such as bumpers and front grilles for the Mercedes G-Class. Beyond production, Alro is increasingly involved in early engineering and prototyping phases, supporting customers several years before the start of production – in some cases as early as SOP 2029. The company contributes to design optimization, develops masking concepts and improves cost efficiency, for example through specially designed transport racks that reduce handling steps. In addition, Alro builds its own production lines based on internally developed concepts and operates according to strict automotive standards, including IATF certification. Its customer base includes main truck companies such as Volvo Truck, Renault Truck, DAF, Scania, and Mercedes. In the automotive sector, Alro is serving major brands as Mercedes (G-Class) and Audi. “Our strength lies in combining technical expertise with the flexibility to serve global customers across different regions and requirements,” says Dirk Broekhoven.
Digital control, sustainability and scalable growth
Managing this complexity requires a strong internal structure. Alro combines its own automation department, IT systems, engineering and quality management with largely digital processes. Communication is handled via EDI- and XML-based systems, supported by internally developed software solutions. In addition, AI-supported tools are being reviewed to analyze market developments and optimize administrative workflows, while robotics and cobots support production processes. At the same time, digitalization is understood as a tool rather than an end in itself, with a focus on improving efficiency and decision-making. Sustainability is firmly embedded in Alro’s operations. The company has been ISO 14000 certified since 1998 as one of the first companies in Belgium and operates its own water treatment and recycling systems. In addition, renewable energy plays a key role, with wind turbines, solar capacity and ongoing evaluations of battery storage solutions. Commercially, Alro is highly international. Only around 20 to 25% of business is generated in Belgium, while the majority comes from abroad. Key markets include Germany, France, the Netherlands, and Sweden, alongside other European countries. At the same time, the company also serves selected global projects, reaching as far as Brazil, while maintaining a core operational radius of around 500 km. Marketing activities include a strong digital presence, active communication on LinkedIn and a dedicated business development function. Alro invests strongly in customer intimacy, organizing dedicated strategic meetings, combined with a proactive communication on all levels in the organization with customers and suppliers. Internally, the company describes itself as an entrepreneurial, organically grown family business with agile decision-making and a high level of process discipline. In the current, somewhat softer market environment, production has shifted from peak levels of seven days a week to around five. As the company looks ahead, its focus remains clearly defined: “We remain one of the biggest manufacturing companies in our region, where we are committed to be an attractive employer, remain relevant and are ready to grow again through our partnership model,” states Michael Segnana.
