A world of solutions for every project

Seventy years ago, we started with a simple idea: creating innovative doors capable of revolutionizing the world of fire protection. Knowing the regulations is the first step in offering truly safe fire-rated doors. We design solutions that exceed standard requirements because when it comes to protection and design, we make no compromises. Today, our doors are certified in many countries and exported to over 60 markets worldwide.

Design and research
We invest in innovation and knowledge
For us, a fire-rated door is much more than a barrier. It’s a safety device designed to save lives, integrate with the architecture, last over time, and simplify installation on-site. This is why we continuously invest in R&D, aiming to improve every product and adapt it to different construction environments.
PRODUCTION
Innovation is at the heart of every project

Automated, monitored, and secure production
Automation serving people. We digitize processes to ensure consistent quality, minimize errors, and enhance human contribution.

High standards, reliable outcomes. Automation enables us to produce doors that meet the highest expectations for safety and innovation.

Production flexibility. The integration of people and technology allows us to adapt quickly and customize every project.

With NDD, the door becomes design. Our exclusive technology allows doors to be decorated with textures, images, writings, or logos, transforming them into design elements that blend with their environment.
