Products & Services
Space Structures develops and supplies high-performance mechanical subsystems for space applications, covering the full lifecycle from design and manufacturing to assembly, testing, and delivery. Our solutions focus on demanding space environments and various architecture, from small satellites to large spacecraft and human spaceflight missions.
Our portfolio and herritage includes spacecraft primary and secondary structures, rideshare and constellation launch systems (such as modular multi-satellite adapters), and precision optical payload structures like telescope assemblies and optical benches where dimensional stability is critical. We also provide electronic equipment enclosures, balancing structural and thermal performance, as well as struts, booms, and sandwich panels used as lightweight building blocks across missions. Each system is delivered as a turnkey solution, combining advanced materials (metal and composites) with integrated engineering, manufacturing, and in-house precision assembly capabilities.
Struts and Booms
Hybrid struts combine lightweight composite material tubes with high-performance metallic fittings, offering a turnkey solution with excellent value for money. Each strut is tailored to the specific application through careful material selection and optimized layup design to achieve the desired mechanical and thermal properties.
The composite tubes can be manufactured using filament winding, thermoplastic, or prepreg technologies and are available in circular, rectangular, or other custom cross-section geometries. The metallic fittings can be produced from aluminium, titanium, Invar, or other materials depending on performance requirements.
The connection between the composite tubes and metallic fittings is achieved through bonded and riveted joints, qualified across a wide range of temperatures and load conditions to ensure reliable structural performance. Additional features such as threads, close-tolerance holes, bearings, and other customized interfaces can be integrated on demand.
To further meet application-specific requirements, metal parts can also receive surface treatments, heat treatment, and special thread inserts such as Helicoil systems.
Honeycomb Sandwich Panels
Space Structures supplies sandwich panels in a wide range of material combinations to meet diverse structural and thermal requirements. Available configurations include aluminium facesheets with aluminium honeycomb cores, GFRP facesheets with aluminium honeycomb cores, CFRP facesheets with aluminium honeycomb cores, and fully composite solutions with CFRP facesheets and CFRP honeycomb cores. NOMEX cores are also available as an optional alternative where required by the application.
To accommodate structural and functional interfaces, the panels can be equipped with a variety of insert solutions. Inserts are available in aluminium, titanium, INVAR, or CFRP and can be designed as floating, face-to-face, edge, or block types. Depending on customer requirements, inserts may include through-holes or threaded interfaces, including optional thread-locking features.
In addition, we offer a unique all-black sandwich panel solution in which the faceskins, honeycomb core, and inserts are all manufactured from carbon-fibre reinforced polymer (CFRP), providing a fully integrated composite structure with outstanding performance and appearance.
Precision Assemblies
Space Structures develops and manufactures high-performance structures for satellites, launchers, optical payloads, and their associated sub-assemblies. The majority of these projects are executed as Build-to-Spec programs, in which we take full responsibility for the complete development process based on customer-provided specifications.
This includes the design, engineering, manufacturing, and performance validation of the structure, with responsibility maintained through to successful verification testing. By managing the entire process from concept to qualification, we ensure optimized solutions tailored to demanding aerospace applications.
Enclosures
Enclosures for electronic equipment have to fulfill a structural and a thermal function, preventing the sensitive electronic components from excessive vibration and heat. Our turnkey solutions include multidisciplinary structural and thermal engineering to guarantee compliant performance.
Spacecraft Structures
Every spacecraft requires a strong and reliable backbone in the form of its primary structure. Space Structures designs and supplies primary structures for applications ranging from microsatellites to large multi-ton spacecraft. With a technology-agnostic approach, we identify the optimal balance between performance, lead time, and cost for each individual project.
Depending on mission requirements, the resulting solution may range from assemblies based on simple CNC-machined panels to highly advanced carbon-fibre honeycomb sandwich structures. Our multidisciplinary engineering approach ensures that all structural, thermal, and functional requirements are fully integrated from the outset. This includes components such as radiators, which must simultaneously fulfill both structural and thermal control functions within the spacecraft architecture.
SpaceBolt Software
SpaceBolt is an engineering software tool used primarily for the analysis and verification of bolted joints in aerospace and high-performance mechanical design. It helps engineers evaluate bolt loads, joint integrity, and safety margins in accordance with industry standards.
The software is commonly used in space and aerospace projects where precise structural validation is critical. It streamlines calculations by integrating with finite element analysis (FEA) results and automates many aspects of bolt checking that would otherwise be done manually. SpaceBolt is designed to improve accuracy, consistency, and efficiency in structural bolt analysis for complex engineering applications.
