Painting of Large Industrial Products

Painting of large industrial products requires custom-engineered systems capable of handling oversized pieces without compromising finish quality. Lesta builds systems for painting of large industrial products and bulky objects, as well as systems for fiberglass and gelcoat spraying.

Our experience in designing and manufacturing automated painting systems, combined with the ability to follow every project through every phase, from feasibility study to after-installation support, allows us to build even large-scale systems, designed to meet the needs of different kinds of industrial production.

What is the maximum size of parts you can paint?

We are able to build painting systems for large parts, sized according to the customer’s specific needs. Our cabins and automation systems reach up to 3.5 meters in height, while for length and width there are no structural limits: the system is sized around the piece, not the other way around. This approach is particularly suited for companies working with components outside standard dimensions who can’t find a truly scalable solution in traditional painting systems.

Here is a practical example of a system in operation: watch the video.

What types of industrial products are suited to systems like this?

In the marine sector we find boats of every type, yachts and hulls, where the aesthetic result of the paint job is often a decisive factor for the perceived value of the finished product. For fiberglass and specialist sectors, we build systems for fiberglass horse shelters and other products made of this material, which require specific painting cycles.

In the earthmoving machinery field we handle components and complete machines for construction and building sites, which must withstand demanding conditions of use while maintaining surface protection over time. For industrial transport, our systems paint trucks, trailers and semi-trailers, ensuring uniformity on large and often irregular surfaces. Finally, for metalworking and structural steel, we work with bars, metal structures, heavy steelwork and oversized components intended for industrial plants or infrastructure.

Why choose Lesta for painting of large industrial products

Choosing a custom-designed solution for painting of large industrial products brings advantages that go beyond productivity alone: a consistent paint thickness across the whole surface, shorter line downtime compared to manual painting, and optimized paint consumption thanks to trajectories calculated on the piece’s actual geometry, instead of standard cycles designed for smaller pieces.

For large metal components, these systems also integrate well with Lesta’s solutions dedicated to industrial metal painting, designed for companies working with heavy steelwork and metal structures across multiple production lines.

Every system is designed together with the customer, starting from the actual dimensions of the pieces and the expected production volumes, to arrive at a configuration that does not force a compromise between part size and finish quality. If you work with products outside standard dimensions and are looking for an automated painting solution designed for your real dimensions, contact us for a technical evaluation of your project.

To cover such large working areas, these systems are often based on cartesian technology, meaning systems that move along linear axes rather than an anthropomorphic arm: a solution that maintains the same trajectory precision even on very large surfaces, without losing repeatability from one piece to the next. This is the same principle behind our cartesian robots, designed precisely for applications where part dimensions exceed what a traditional anthropomorphic robot can handle.

A Lesta technician can analyze the drawing and volumes of the piece and propose the most suitable configuration, even for productions that are not yet standardized.
