HISTORY OF STARMODUL
History of StarModul: Manufacturers of metal structures and creators of the patented system
StarModul develops and manufactures its own system of metal structures with bolted connections. We invented the system, manufacture StarModul components, and have secured patent and industrial design protection for them.
Who we are
Over 25 years in steel structures
This page traces the evolution of StarModul: from the initial idea and the development of the first connectors to manufacturing in Spain, the system’s applications, and its digital evolution.
We have spent more than 25 years in sandwich panels and steel structures and more than 10 manufacturing StarModul joints, with 4,000 m² of facilities in Torre-serona (Lleida) and over 1,000 completed projects.
- Bolted joints, no welding on site
- Patented system
- Structural design by an engineer for every project
- CE marking to harmonised standard EN 1090-1

OUR HISTORY
Manufacturers of metal structures and creators of the StarModul system
StarModul was not created as a commercial adaptation of someone else’s product. We are the inventors and manufacturers of the StarModul system, a proprietary solution for building bolted metal structures. We design the connections, secure their industrial property rights, and manufacture the fasteners that transform structural profiles into a modular building system.
The innovation lies in the connector: components designed to precisely position and connect steel profiles, allowing the structure to be pre-assembled and enabling a dry, modular, and organized installation. You can learn about the construction principle for steel structures with bolted connections and explore further details on how the StarModul system works.

STARMODUL TIMELINE
The Evolution of StarModul Metal Structures
A structured evolution in seven milestones: from the initial idea to the development, protection, manufacturing, and digitization of the system.
ORIGIN
The idea: to simplify the joining of metal profiles
The starting point was simple: to put up a metal structure, however small, you had to weld and make life complicated. We were looking for something simple and easy to do. StarModul offers an alternative: specialized mechanical connections that allow certain joints to be assembled using fasteners and facilitate the assembly process.
DEVELOPMENT
StarModul Connections Are Born
The idea takes shape as a family of structural tube components. Joints are developed that can accommodate various connections, geometries, and configurations using identifiable, repeatable components designed for modular assembly.
PROTECTION
The system is protected as an in-house development
StarModul promotes the industrial protection of its solution. The brand’s technical and commercial documentation identifies the system as patented and also notes that it is protected by a Community Design Registration.
DOCUMENTED MILESTONE
The system is already documented as a patented product
The 2017 StarModul catalog publicly presents the system as a patented product and includes CE marking in accordance with EN 1090-1:2011+A1:2012, thereby consolidating its technical and commercial development.
MANUFACTURING
From Invention to Manufacturing in Spain
StarModul does more than just market an idea: it manufactures the metal connectors that form the core of the system. This allows the company to control geometries, part numbers, compatibility, and the evolution of the various part families.
APPLICATIONS
The system is being extended to new types of structures
The versatility of the connections allows the system to be used in homes, industrial buildings, roofs, additions, bungalows, canopies, supports for installations, and other custom-made metal structures.
DIGITAL EVOLUTION
3D Modeling and a New Era of Industrialization
StarModul incorporates digital tools such as the 3D steel structure configurator to analyze initial geometries and obtain preliminary information about components before the final technical definition.

WHAT SETS US APART
Proprietary metal structures, designed and manufactured by StarModul
The relationship between the design, manufacturing, and practical application of our metal structures is essential to understanding the brand. Our knowledge of the system stems from having developed it and continues through its manufacturing, technical evolution, and adaptation to real-world projects.
Inventors and Developers
The concept, connections, and structural logic of the StarModul system have been developed to create modular metal structures using bolted connections.
Manufacturers
We manufacture StarModul metal fasteners in Spain and develop the necessary product families to address various joint configurations and applications.
Patented system
The industrial protection of the system and its design reinforces the unique nature of a solution specifically designed for the assembly of metal structures using mechanical fasteners.

FREQUENTLY ASKED QUESTIONS
About the History and the StarModul System
Who invented the StarModul system?
StarModul is a system developed by our own team. We are the creators of the structural concept, its families of connections, and the system’s technical evolution.
Who manufactures StarModul connectors?
StarModul manufactures its own metal fasteners in Spain and applies the system to the development of bolted metal structures. We are not merely distributors: we are the manufacturers of the system and its specific components.
Is StarModul a patented system?
Yes. StarModul’s technical and commercial documentation identifies the system as patented and also notes that it is protected by a Community Industrial Design Registration.
What problem does StarModul solve?
StarModul allows compatible joints in a metal structure to be assembled using mechanical connections and fasteners, reducing the need for welding during assembly and facilitating a modular, dry-assembly process that is planned in advance.
What types of structures is it used for?
It can be used for homes, industrial buildings, roofs, additions, bungalows, porches, canopies, solar structures, and other custom projects. Each structure must be designed based on its geometry, loads, use, and location.

APPLICATIONS
