StarModul is a patented dry-construction system for bolted metal structures. It allows structural profiles to be assembled using precision mechanical connections, eliminating the need for welding at joints and simplifying the assembly of structures of various shapes and sizes.
The system can be used with structural or solid tubing, with square or rectangular cross-sections, and is designed to streamline the assembly process: preliminary design, predefined components, bolted connections, and clean installation directly on-site.
Mechanical connections for assembling the structure without welding the joints.
A system designed to simplify and speed up assembly work.
It allows for the construction of structures of various sizes and configurations.
Profiles and thicknesses sized according to the project's loads and characteristics.
A bolted metal structure uses mechanical connections to join the sections that form columns, beams, frames, roofs, floor slabs, and other load-bearing elements. At StarModul, each joint is designed with a specific component that positions the sections and allows them to be secured with bolts.
By eliminating the need for welding during assembly, the installation can be carried out using conventional tools and a much more organized process. The system reduces the need for on-site adjustments and facilitates the preparation of materials in advance.
Its modular design allows for different configurations and, depending on the series used, enables work with steel, iron, aluminum, or wood profiles, as well as solutions compatible with IPN and HEB beams.
The result: a system of modular, demountable, dry-assembly metal structures that can be adapted to residential, industrial, and commercial projects.
Steel tubes used to form columns, beams, and load-bearing elements.
Parts specifically designed to untie different types of knots.
Mechanical fastening of the profiles to the structural joints.
The configuration and thickness of the profiles are determined on a case-by-case basis for each structure.
The system transforms the traditional assembly of a steel structure into a pre-designed and organized assembly process.
The geometry, dimensions, modularity, and positions of columns, beams, frames, and other necessary elements are defined.
Profile dimensions, thicknesses, joints, and fasteners are determined based on the specific loads and conditions of the project.
Profiles, joints, and components are organized according to the project documentation to simplify their identification on-site.
The profiles are assembled using StarModul connectors and the corresponding fasteners until the structure is complete.
StarModul connectors are manufactured from 3 mm-thick alloy steel, cold-rolled, and protected against corrosion by a zinc-plating process. The published technical documentation also includes chromate passivation and electrolytic finishing. For special applications, specific alloys—including stainless steel—can be considered.

Square tubing: 100×100, 50×50, and 25×25 mm. Rectangular tubing: 100×50 mm. The published documentation indicates compatibility with different wall thicknesses.
The system’s efficiency is based on connections that are fully accessible via fasteners. Assembly can be performed using standard tools—fixed wrenches, open-end wrenches, or ratchet wrenches—without the need for welding equipment.
The currently published specification calls for zinc-plated hex head screws conforming to DIN 933 (ISO 4017), class 8.8, M10×20. The assembly is completed with class 8.8 or 6.8 hex nuts featuring a neoprene self-locking element to reduce the risk of loosening due to vibration.

A system designed for clean, modular, and mechanically assembled installation.
The StarModul system combines the advantages of a metal frame with a mechanical assembly process: fewer on-site operations, high modularity, and the ability to disassemble or modify the structure.
Mechanical fasteners are used instead of welding when assembling profiles.
Pre-assembly and pre-screwing reduce the number of steps and simplify on-site installation.
The structure can be dismantled, modified, or expanded when the design and structural calculations allow it.
The components are predefined to facilitate squaring, positioning, and identification.
The different families of joints make it possible to accommodate a wide variety of geometries and configurations.
Homes, warehouses, pergolas, roofs, solar structures, enclosures, and custom projects.
The main difference between the StarModul system and a welded steel structure lies in how the joints are constructed. The bolted joints used in steel structures connect the profiles using specific mechanical fasteners, so that assembly can be performed off-site without having to weld each joint on-site.
This approach makes it possible to plan the structure before assembly, organize profiles, joints, and fasteners, and reduce ancillary work. The result is a more industrialized, clean, and easily repeatable process.
StarModul allows you to develop custom metal structures and to supply self-assembly structural kits with components prepared to facilitate installation.
For simple projects, you can also use the 3D metal structure configurator to define an initial geometry and determine the necessary components.
The system is suitable for residential, industrial, and commercial projects thanks to its various series of profiles and connectors.
