Flexibility for new builds and renovations

Thanks to the double box system, the GRIMM letterbox can be prepared in the shell and completed at a later date with a front panel and technology modules. Ideal for projects with staggered construction phases, it also allows building owners to replace the front panel - for example, when installing a new intercom system or changing the design.

High-quality letterbox - made from durable stainless steel

Stainless steel with a polished surface is currently experiencing a real renaissance in high-quality interior design and in the architectural living environment. Whether in kitchens, furniture handles, wall panelling or stair railings - the elegant, matt finish has a modern, professional and understatedly exclusive look.

The GRIMM letterbox consistently picks up on this trend: With its finely polished stainless steel surface, it fits seamlessly into modern design concepts in which materiality and feel play a decisive role. The polished stainless steel sets stylish accents and creates a harmonious connection between inside and outside, particularly in the transition area between the living space and the exterior façade - i.e. in the entrance area.

Made from V2A stainless steel, the GRIMM offers extremely high corrosion resistance, durability and lasting value. Stainless steel is not only easy to clean, but also fully recyclable - a clear plus for the environmentally conscious.

Advantages of stainless steel:

• Corrosion protection: ideal for outdoor use

• Easy to clean: dirt-repellent surface

• Weather-resistant: No deformation or fading

• Recyclable: Sustainable material with a low ecological footprint

All letterboxes are manufactured in the factory in Bad Salzuflen - with precision craftsmanship and state-of-the-art production technology.

Sustainability and future-proofing

A high-quality designer letterbox should not only look good today, but also function reliably in the future. The GRIMM is impressive in this respect thanks to:

• Modular design: individual parts such as flaps, panels or communication modules can still be replaced or added to years later.

• High-quality workmanship: No cheap plastic parts - just durable, solid stainless steel.

• Resource-conserving production: Short supply chains, responsible supplier selection, durable materials.

The GRIMM letterbox therefore fulfils all the requirements of a sustainable product - from both an ecological and economic perspective.

Whether for a detached house, a modern residential complex or an architectural project - the GRIMM letterbox impresses as a high-quality designer letterbox that combines stylish aesthetics with state-of-the-art technology. Its versatility, compatibility with leading door communication systems and sustainable design make it the ideal choice for anyone looking for more than just a letterbox.
