SurfaceTechnology GERMANY 2028: visitor guide

SurfaceTechnology GERMANY is an international trade fair for industrial surface treatment and finishing. The next edition is announced for 20–22 June 2028 at Messe Stuttgart in Stuttgart, Germany. Surface technology is a cross-sectional process: it is used across metals, plastics, electronics, automotive, medical technology, aerospace, precision engineering and other industries. The fair combines product and process displays with the STG.ExpertForum, making it relevant both to people selecting technologies and to teams responsible for production quality, resource use and technical performance.

Why SurfaceTechnology GERMANY matters

Compare processes and materials

The organiser lists technologies ranging from pre-treatment, cleaning and electroplating to thermal spraying, industrial plasma and laser-based treatment, coating materials, measurement and analysis. This breadth helps visitors compare where process choices affect surface quality, durability, appearance and function. Buyers can use consistent criteria—substrate, desired property, throughput, environmental requirements and service support—when evaluating different approaches.

Connect process decisions with end-user industries

The official visitor industries include metal processing, automotive, mechanical engineering, plant and apparatus engineering, electrical industry, medical technology, aerospace, plastics, precision engineering and jewellery. A surface-treatment solution therefore needs to be assessed in its application context, not only by its technology label. Production engineers may prioritise process control and repeatability, while procurement teams may focus on fit, supplier support and lifecycle requirements.

Use the ExpertForum to add technical context

The organiser reported around 50 STG.ExpertForum presentations in 2026, including cleaning and pre-treatment, new electroplating processes, PFAS avoidance, AI support, surface technologies for energy applications, energy and material efficiency, digitalisation, thermal spraying and PVD/CVD. These are examples from the previous edition; the 2028 programme should be checked when it is released.

Latest published scale

The 2026 after-show report recorded more than 4,600 trade visitors from 46 nations and more than 210 exhibitors from 21 nations. The organiser also reported that 30% of visitors and 37% of exhibitors came from abroad. These figures describe the 2026 edition, not an attendance forecast for 2028.

Who should visit SurfaceTechnology GERMANY?

Surface-treatment engineers and production managers

Useful if you specify or operate coating, cleaning, electroplating or other surface processes. Compare technologies against the substrate, required finish, production volume, quality controls and environmental conditions of your process. Ask how suppliers measure results, control variation and handle maintenance or process changes. The organiser positions surface technology as a cross-sectional process used across many industries.

Manufacturing buyers and technical teams

Useful if you work in metal processing, automotive, mechanical engineering, plant construction, electrical manufacturing, medical technology, aerospace, plastics or precision engineering. Identify the surface property that matters to your product—such as durability, appearance or function—and compare relevant systems, materials and services. The official event page lists these industries among the show’s visitor sectors.

Coating, equipment and service suppliers

Useful if your company supplies surface-treatment equipment, coating materials, process services, testing or environmental systems. The cross-industry audience creates an opportunity to explain applications to different customer groups, but product fit varies by substrate and production context. Prepare examples that clearly identify the process, application conditions, measurable result and support requirements.

What makes SurfaceTechnology GERMANY different?

The show treats surface technology as a cross-industry production capability rather than a single end market. Its official positioning links processes and materials with manufacturing sectors from automotive and metalworking to medical technology and aerospace. The ExpertForum adds technical perspectives: in 2026, the organiser described around 50 talks and demonstrations covering topics such as new electroplating processes, AI, PFAS, energy efficiency and PVD/CVD. This mix can help a visitor connect a process discussion with the wider engineering or production context; the next forum programme may differ.

What should you aim to achieve?

If you are a process engineer

Set an objective such as: compare two or three process approaches for one substrate and document the performance, control and maintenance evidence needed for a trial. Bring the target finish, operating constraints and quality requirements. Ask suppliers to distinguish demonstrated performance from application assumptions.

If you are a manufacturing buyer

Set an objective such as: identify a shortlist of suppliers who can address one defined surface property or production bottleneck. Record material compatibility, process steps, installation needs, environmental considerations and service coverage so that options can be compared consistently.

If you are an exhibitor

Set an objective such as: explain one application clearly to a priority customer segment and capture the technical information needed for a qualified follow-up. Prepare different examples for different substrates or industries rather than treating all visitors as if they share the same process challenge.

How to prepare before SurfaceTechnology GERMANY

1. Define the surface problem

Describe the substrate, current process, required finish or function, production conditions and the issue to solve. Is the priority corrosion resistance, wear, cleaning, appearance, adhesion, conductivity, energy use or another defined property? A precise brief helps you avoid comparing technologies that solve different problems.

2. Map the process chain

Note where the surface-treatment step sits in production: pre-treatment, cleaning, coating or finishing, measurement and quality control, wastewater or environmental systems, and downstream assembly. Identify interfaces with existing equipment and any change-control requirements. This lets you discuss a system rather than a stand-alone machine.

3. Build a shortlist from the directory

When the 2028 exhibitor and product directory is available, sort companies into A (relevant to a live project), B (useful alternatives or suppliers) and C (explore if time allows). Group them by process and material so your comparisons remain meaningful. The 2026 exhibitor report counted more than 210 companies, but the 2028 exhibitor list is not yet confirmed.

4. Prepare technical questions

• Which substrates, geometries and production volumes is the process designed for?
• What measurable properties or test methods support the claimed result?
• How does the system control process variation and document quality?
• What pre-treatment and downstream steps are required?
• What are the energy, water, material and consumables requirements?
• How are emissions, waste streams and environmental controls handled?
• What maintenance, training, commissioning and service support is needed?
• Which standards, certifications or customer approvals apply to the intended use?

5. Select relevant forum sessions

Use the 2026 STG.ExpertForum topics as a guide to the kinds of subjects previously discussed, not as a confirmed 2028 schedule. Once the new programme appears, choose sessions that address your process, regulatory or resource-efficiency questions and leave time to discuss relevant points with exhibitors.

How to make the most of the exhibition

Use the same comparison note for each supplier: company → process or material → substrate/application → evidence → production fit → next action. For a coating process, for example, record the material, pre-treatment, target finish, quality test, operating conditions and service requirements. For a measurement system, note the measured property, accuracy requirement, sampling approach and how results feed into quality records.

Do not compare a presentation’s headline result with another supplier’s result unless the test conditions are comparable. Ask what evidence is available for your actual substrate and production environment, and record which questions require a sample, technical review or plant trial.

Plan your time realistically

The 2028 event is announced for three days. If you have one day, prioritise the process area most closely connected to your production need and the ExpertForum sessions that address it. With more time, compare alternatives across treatment, materials, measurement and environmental systems, then reserve a period to revisit suppliers with unresolved questions. Check the official opening hours and the final programme before travel; the schedule for 2028 is not stated in the event information reviewed.

Beyond the exhibition floor

The 2026 STG.ExpertForum brought together around 50 presentations and demonstrations over three days. The reported topics included new electroplating processes, cleaning and pre-treatment, PFAS avoidance, AI support, surfaces for energy technology, energy and material efficiency, digitalisation and physical surface-treatment processes such as thermal spraying and PVD/CVD. Use these examples to identify questions worth following, but confirm the 2028 forum agenda before planning around a particular subject or speaker.

The 2026 edition also included the Stuttgart Surface Technology Award and a Process Chain Surface Technologies group presentation. These are previous-edition examples; verify which special activities return before treating them as part of the 2028 programme.

Bring a live production project

For a current project, prepare a concise technical brief: substrate and component geometry, production volume, current surface process, required property, acceptance test, quality limits, environmental constraints, installation space, delivery stage and service expectations. If a problem concerns a failure or quality issue, bring non-confidential measurements or images where appropriate. A shared brief helps suppliers identify what additional information is needed for a meaningful technical assessment.

After SurfaceTechnology GERMANY: turn comparisons into decisions

Sort contacts into A (current process or investment decision), B (potential alternative or future project) and C (market intelligence). For A suppliers, request process specifications, test evidence, system requirements and service details. Compare options against the same substrate, output property, quality-control method, environmental conditions and total operating needs. Include production, quality and environmental colleagues in the review where their requirements affect approval.

Record the reason for each next step. A supplier may be technically promising but unsuitable for the current production line; another may require further testing before comparison. Set an owner and date for samples, plant trials, quotations or engineering reviews. This protects the value of the visit from becoming a stack of unprioritised catalogues.

Who should consider exhibiting?

The organiser’s categories include measurement and analysis, pre-treatment, thermal spraying, environmental and supply systems, nano- and microtechnology, plasma and laser treatment, coating materials, cleaning, abrasive blasting, electroplating and services. Exhibiting may suit equipment manufacturers, coating-material suppliers, process specialists, testing and environmental-system providers and other surface-technology firms. Before committing, define the customer industry, substrate and application you want to reach, and prepare a demonstration or technical explanation that makes the application clear. The 2026 edition included more than 210 exhibitors from 21 nations; this is not a 2028 exhibitor forecast.

Surface technology opportunities in Germany

Market context

Germany’s Federal Statistical Office reports that manufacturing accounted for 19.9% of gross value added in the German economy in 2024. This is a broad manufacturing measure, not a statistic for surface-treatment suppliers specifically. The fair’s own visitor-industry list spans metal processing, automotive, mechanical engineering, electrical manufacturing, medical technology, aerospace, plastics and precision engineering—industries where surface properties can affect product quality, durability and function.

Opportunities for exhibitors

• Surface-treatment suppliers may explore conversations with manufacturers in the sectors named by the organiser and test which substrate, finish or production challenge best matches their offer.
• Equipment, materials and environmental-system providers could use the cross-sectional audience to identify relevant technical partners and customer requirements, subject to their own product fit and qualification needs.

Opportunities for visitors

• Manufacturing teams may compare process, material and measurement options against a real component or production requirement.
• Buyers and engineers could use the event to investigate how surface treatment supports product quality and durability across different manufacturing applications, then verify suitability through technical evidence or trials.

Germany may be relevant to surface-technology participants because manufacturing represented a substantial share of national value added in 2024 and the fair brings together visitors from multiple manufacturing sectors. The statistic does not guarantee demand for a particular product; fit depends on the application, process requirements and customer qualification.

Discover Stuttgart

Stuttgart’s official tourism partner highlights the city’s automotive heritage and lists the Porsche Museum and Mercedes-Benz Museum among its major attractions. Messe Stuttgart is in the city; both museums are Stuttgart attractions, separate from the exhibition grounds.

Porsche Museum

The official Stuttgart tourism site identifies the Porsche Museum as a city highlight. It offers visitors an automotive-focused stop that complements the region’s industrial identity.

Mercedes-Benz Museum

Also listed as a Stuttgart highlight, the Mercedes-Benz Museum presents another perspective on the city’s automotive and engineering heritage.
