Technical Springs for Building Services Engineering
Manufactured for industrial applications according to customer specifications
We manufacture wire-formed springs, stamped and bent parts, compression springs, and other technical springs for building services engineering. Manufactured according to drawings, samples, or specifications, and designed to withstand humidity, temperature fluctuations, and heavy use over many years.
Advantages
Corrosion- and chemical-resistant materials for plumbing, HVAC, and heating systems.
Designed to withstand a large number of load cycles in door, window, and hinge mechanisms.
Assemblies & Custom Packaging
Upon request, pre-assembly and process-specific packaging for the assembly line are included.
We understand the challenges
in building services engineering
Building services components are often in use for decades, frequently in areas with high humidity, temperature fluctuations, or exposure to water and cleaning agents.
Even a worn-out return spring in a door closer or a corroded clamp on a heating valve can lead to costly repairs.
We supply springs and wire-formed parts that deliver on the long-term performance of your components.
We use corrosion-resistant spring steels (e.g., 1.4310 or 1.4401) that can withstand damp indoor environments, splashing water, and chemical exposure from cleaning agents.
Heating, ventilation, and air conditioning systems are exposed to fluctuating temperatures. Our springs are designed so that their spring force and function remain consistent even under thermal stress.
Springs used in door, window, or hinge mechanisms must remain stable over a large number of cycles. We design the geometry, material, and spring characteristics to meet the required service life.
With easy-to-install click-and-clip solutions, we reduce installation and service times—a clear advantage given the shortage of skilled workers in the trades.
Through process monitoring, careful material selection, and comprehensive documentation, we ensure traceability and reduce complaints throughout the product’s entire service life.
Areas of Application
Where Our Technical Expertise in Building Systems Makes a Difference
We manufacture precision components for key areas of building systems, exactly according to your drawings, samples, or functional requirements.
Door, Window, and Fire Protection Technology
Ensure the functionality and safety of movable structural components throughout their entire service life.
Wire-formed springs and leaf springs for door closers, window hardware, and swing-wing actuators, designed to withstand a large number of cycles.
Specified return forces for technical applications on fire-rated doors, combined with suitable spring materials for applications subject to thermal stress.
Stamped and bent parts for the tool-free, repeatable installation of hardware and gaskets.
Blackout, Sun Protection, and Shading Technology
Moving components that are used daily and must function reliably over the long term.
Consistent force characteristics throughout the entire operating range for roller shutters, awnings, and interior roller blinds.
Torsion springs and extension springs that reliably assist in opening and closing the gate for many years.
Wire-formed parts for securing slats, guide rails, and end caps.
Plumbing Technology
Springs for components that are operated many times a day and come into contact with water.
Compression and return springs made of stainless spring steel, designed for high cycle counts and chemical exposure.
Tension springs and wire-formed parts for lifting and release mechanisms.
Return springs for showerheads, diverter valves, and hose holders, designed to be limescale-resistant.
From Prototype to "
" Production Part
From prototype to mass production in record time. Are you developing a new application for building services engineering? We can quickly produce samples for you or advise you on prototype manufacturing so you can test the spring force and fit in real-world conditions. This helps you minimize your risk before starting mass production.
The Sketch / Idea
Do you have an idea, a rough sketch, or a 2D/3D drawing for a new mount?? We review your functional requirements and advise you on the optimal design . Even at this stage, we take into account the installation situation, available space, and environmental conditions, in order to streamline the subsequent manufacturing process.
The Prototype
Before your part goes into production, we’ll quickly produce prototype parts or a small batch to verify its functionality.. This allows you to test spring force, holding force, and fit directly on the object. This minimizes your development risk, refines the geometry, and provides you with maximum assurance before the start of series production.
The Production Part
Once approval is granted, we will transition seamlessly to mass production. With continuous process monitoring, we process certified materials to ensure long-term stability. Upon request, you can receive your components ready for assembly or in special packaging tailored to your logistics needs..

Questions and Answers: Technical Springs for Building Services Engineering
What information do you need to provide a quote?
Ideally, a drawing (2D/3D) or a sample part. Additional information such as the installation situation, desired spring force, available space, quantity, and operating environment (e.g., damp locations, contact with cleaning agents, temperature range) is also helpful.
Do you also manufacture prototypes or sample parts for building services components?
We provide you with detailed guidance on prototype development and, based on this, deliver samples or a small production run for functional validation before seamlessly transitioning to mass production.
What materials do you use for wet areas and plumbing applications?
For applications involving corrosion and chemical exposure, we use stainless spring steels such as 1.4310 or 1.4401. Upon request, we can supplement the material selection with appropriate surface treatments.
Can you design springs for high cycle counts, such as in door closers or valves?
Yes. We specifically design the geometry, material, and spring characteristics to meet the required service life, ensuring that the spring force remains stable even after millions of cycles.
Do you supply only individual parts, or do you also supply pre-assembled units?
Upon request, we also supply subassemblies, kits, and custom packaging to simplify your assembly and logistics processes.
How do you ensure documentation and process reliability?
Through process monitoring, clear specifications, and comprehensive documentation, we ensure traceability that protects you in the event of a complaint or warranty claim.
