ADVANTAGES OF THE STARMODUL SYSTEM
Advantages of StarModul Bolted Metal Structures
Metal structures are known for their strength, durability, versatility, and lighter weight. The StarModul system offers an additional advantage: the profiles are assembled using bolted connections, eliminating the need to weld the joints during installation. The tubes arrive cut to size and every part labelled, with step-by-step assembly plans: on site there is nothing to cut or weld, you just bolt it together.
Why bolted
Less work on site, more control over assembly
This construction method simplifies the building process, reduces on-site work, and enables the development of modular structures that can be adapted for homes, industrial buildings, roofs, additions, solar installations, and custom projects.
Parts arrive cut and labelled and are assembled following the drawings, with ordinary tools and no welders. That is why the system works for a house, a warehouse, a porch or an extension alike, and the structure can be dismantled or extended later.
- Bolted joints, no welding on site
- Patented system
- Structural design by an engineer for every project
- CE marking to harmonised standard EN 1090-1

KEY BENEFITS
Advantages of Building with a Steel Frame
In addition to the inherent advantages of structural steel, StarModul aims to simplify the manufacturing and assembly process through mechanical connections designed to work with tubular profiles and other compatible solutions.
Screw-type assembly without welding
Joints are connected using mechanical fasteners. This reduces welding work, sparks, fumes, and operations associated with weld beads.
Modular, collapsible, and expandable
The structure can be dismantled, modified, or expanded as long as the new configuration is compatible with the design and structural analysis.
Lower weight
Lightweight metal structures transmit less dead load than heavy-duty solutions, which can be useful in renovations and additions.
Recyclable and reusable material
Steel is recyclable, and the bolted design makes it easy to recover components or reuse parts of the structure in new configurations.
Accuracy and Repeatability
The geometry is defined in advance, and the connectors help position the profiles, facilitating a more orderly and repeatable assembly.
Design Freedom
The variety of connections and configurations makes it possible to design frames, roofs, modules, enclosures, and special structures.
PRODUCTION AND EXECUTION
Advantages of Screw-Based Assembly
The StarModul system is designed to streamline the assembly of a metal structure. Many operations that, in a welded solution, require preparation, squaring, tack welding, and welding are instead accomplished using connecting parts and fasteners.
- Connectors help position and square the profiles during assembly.
- The tubes can be cut at 90° angles for use in multiple system configurations.
- This reduces the reliance on welding equipment during assembly.
- The fastening is accessible and verifiable via screws.
- In pre-assembled kits, the components can be identified and organized before they arrive on-site.
- The tolerances of certain joints make it easier to accommodate minor assembly adjustments.
COMPARISON
StarModul vs. Traditional Welded Assembly
Not all structures or joints are constructed in the same way. This comparison summarizes the differences in the construction process between a structure assembled with StarModul joints and a conventionally welded structure.
StarModul System
- Joints made with bolted connections.
- No welding is required during the assembly of StarModul joints.
- Less exposure to sparks and hot work.
- Removable and replaceable components.
- Modular design and the possibility of future modifications.
- Preparation and logistics can be simplified using kits.
Traditional welded structure
- Joints require welding operations.
- Greater reliance on specialized welding personnel.
- Hot work and associated safety controls.
- Subsequent modifications may require cutting and rewelding.
- A higher number of set plays in certain games.
- Prefabrication and transportation may require larger components.
COST AND LOGISTICS
How can it help reduce costs?
Cost savings do not depend solely on the price of steel or fasteners. In a steel structure, the final cost is heavily influenced by assembly time, auxiliary equipment, shop preparation, logistics, and future modifications.
Fewer specialized procedures
Eliminating the need for welding on StarModul joints reduces the number of hours of specialized labor required during assembly.
More Flexible Logistics
Transporting individual profiles and joints may be easier than moving large, pre-welded assemblies.
Fewer mounting hardware items
In compatible structures, the need for certain auxiliary equipment associated with welding and prefabrication can be reduced.
Cleaner Construction Site
Dry construction generates less waste than wet processes and avoids waste resulting from welding operations.
Lower modification costs
A bolted structure makes it easier to replace, remove, or rearrange components compared to permanently attached solutions.
Material Optimization
The modular design and calculations allow you to select profiles and thicknesses based on the project's actual needs.
WEIGHT AND FOUNDATION
Lightweight Structures and Foundation Optimization
One of the advantages of steel structures is their high strength-to-weight ratio. Reducing the structure’s dead weight decreases the permanent loads transmitted to the building or the ground.
In certain projects, this can make it possible to optimize the foundation or make modifications to existing buildings with less additional load. The foundation solution must always be determined through the corresponding structural and geotechnical calculations and technical design.
MODULARITY AND SUSTAINABILITY
A collapsible and reusable structure
The bolted system allows the structure to be designed as a set of components that can be separated. This facilitates repair, maintenance, adaptation, and—when technically feasible—reuse.
Recyclability
Steel can be recycled at the end of its useful life and reincorporated into new production cycles.
Dismantlability
Mechanical connections make it possible to separate components without necessarily destroying the entire structure.
Extensions
Its modular design makes it easier to explore expansions or new configurations with minimal intervention.
Maintenance
An accessible part or component can be inspected and, when necessary, replaced on a localized basis.
VERSATILITY
More than 100 bolted joint configurations
The variety of StarModul joints makes it possible to create straight connections, corners, intersections, slopes, and connections in different directions. This expands the design possibilities compared to systems based on a single standard joint.
- Custom metal structures.
- Housing and prefabricated modules.
- Industrial buildings and warehouses.
- Roofs, pergolas, and porches.
- Structures for solar panels.
- Fences, enclosures, and outdoor furniture.
- Expansions and renovations.
ON-SITE CONSTRUCTION
A cleaner and more controllable assembly process
Eliminating welding at the StarModul joints changes the working conditions during assembly. This does not mean that the risks inherent in a metal structure disappear, but it does eliminate the need for certain hot work operations.
No welding required at the joints
The StarModul assembly process eliminates the sparks, fumes, and radiation typically associated with welding.
Accessible Tools
Screw fastening allows many operations to be performed using hand tools or conventional tightening tools.
Drywall Construction
Installation does not require water or any mixtures to make the structural connections.
Verifiable process
The accessibility of the fasteners facilitates visual inspection and quality control of the assembly.
Advantages of a metal structure that does not require on-site welding
A bolted steel structure combines the performance of steel with the flexibility of a detachable mechanical connection. In StarModul, bolted joints for steel structures allow for weld-free connections during assembly.
For projects where the timeline, logistics, or the possibility of future modifications are important, this system can offer advantages over a welded structure. You can learn more about the process on our page about assembling metal structures.
StarModul also develops custom metal structures and self-assembly metal structure kits designed to simplify component identification and assembly.
