High-end glass doors: why leading manufacturers are investing in sandblasting, marking and protective coatings
In the high-end entrance door and premium window sector, glass is taking on an increasingly strategic role. In many cases, it is no longer just a functional component but a decorative surface capable of adding significant value to any environment or building and of defining the style of an entire collection. Today, the quality and type of glass surface finish—soft satin effects, geometric patterns, shaded gradients, permanent markings and custom textures—directly influence product perception and brand identity.
For this reason, a growing number of manufacturers are increasingly choosing to bring glass processing in-house, performing all finishing and decoration operations internally without relying on external suppliers. This approach ensures total control over design and every stage of the production process, guaranteeing industrial repeatability, precision and greater competitiveness on the market.
The use of glass in premium entrance doors
In contemporary design, glass increasingly interacts with materials such as aluminium, steel and composites, helping to create entrance systems that are aesthetically coherent and perfectly balanced. Soft satin finishes, calibrated opacity, geometric patterns and micro-textures make it possible to obtain elegant, distinctive surfaces that enhance both high-end entrance doors and premium window systems. Permanent marking adds an additional level of customization: logos, house numbers and graphic elements can be integrated into the glass in a discreet, precise and long-lasting way, becoming a true signature of the brand.
Alongside the aesthetic component, the need for protection and durability is becoming increasingly significant. Next-generation coatings play a key role in this respect: they reduce dirt absorption, protect glass surfaces from atmospheric agents and simplify cleaning operations, keeping the glass bright for longer. The result is a product that maintains its aesthetic value over time and requires fewer post-sale interventions—offering tangible benefits for both manufacturers and end customers.
Why more companies are choosing automatic sandblasting
Manufacturers of high-end doors see automatic sandblasting as a true accelerator of quality and productivity. The ability to achieve flawless, repeatable and highly sophisticated surfaces has redefined the role of glass not only in exterior doors but also in designer interior doors and window systems with satin or decorated glass panels. Compared to outsourced or semi-manual processes, automatic sandblasting offers:
- Repeatability and uniformity of results, essential for premium collections.
- Direct control over decorations, including shading, transitions and selective privacy areas.
- Reduced production times, thanks to smoother internal workflows.
- Large-scale customization, which the market increasingly requires.
The combination of sandblasting, permanent marking and protective coatings allows manufacturers to offer doors and windows with higher-performing surfaces—more elegant and more consistent with the brand’s identity.
RL Series: the sandblasting machine designed for door and window production lines
The RL Series is designed to optimise the sandblasting process for companies producing entrance doors, interior glass doors and high-end window systems. Unlike standard models that operate from left to right, the RL operates from right to left, enabling more efficient integration into production lines that require opposite directions.
This configuration makes it possible to place an RL next to a standard sandblaster, creating a symmetrical layout that facilitates loading, processing and transfer without interruption. When integrated with vertical washers or other machines for glass preparation and finishing, the RL helps create a continuous, well-balanced and space-optimised production flow.
Designed for glass panels of various sizes, it ensures:
- stable material handling
- uniform satin finishing and decoration
- reduced transfer times
- easy operator use
- consistent quality across batches of any size
For manufacturers producing thousands of doors every year, this translates into greater efficiency, improved ergonomics and perfectly repeatable results.
