Traffic Solutions

Traffic Solutions is part of 3A Composites Display Europe, an international division within the 3A Composites Group.

Traffic Solutions offers material solutions for traffic engineering, focusing on aluminium composite panels for traffic signs and transparent plastics for sound barrier walls.

As inventor of the first aluminium composite panel and with more than 50 years of manufacturing experience, we are able to make a decisive contribution in the field of sustainability by providing DIBOND®traffic as a substrate for road signs.

3A Composites produces transparent plastics at various locations throughout Europe for sound barrier applications. We offer our customers extruded acrylic sheets (CRYLON® Sound Barrier Wall and PERSPEX® XT Sound Barrier Wall) as well as extruded polycarbonate sheets (IMPEX®).

Traffic Signs

Full video here


DIBOND®traffic is a high-grade aluminium composite panel comprising two aluminium cover sheets and a core. The panel satisfies the most rigorous requirements in terms of mechanical stress as well as weather resistance and has a 12-year manufacturer’s guarantee.

As the panel contains less aluminium than conventional solutions, DIBOND®traffic makes a major contribution to sustainability in traffic engineering. The manufacture of the polyethylene core material, which is laminated between the covering layers, generates an amount of greenhouse gases which is five times lower than in aluminium production. The high-tensile alloy used for the panel’s thin aluminium covering sheets means the overall composite material is equivalent to a solid sheet. No other aluminium composite panel on the market provides properties and availability to compare with DIBOND®traffic.

DIBOND®traffic’s exceptional qualities, in particular its light weight and easy processing, make creating even the most complex shapes and forms economical and sustainable – and herald a new era for variable message signs! By satisfying national and international standards, DIBOND®traffic has been validated as a high-quality product and equivalent to conventional materials for traffic signs.

In 2020, we achieved another milestone in the DIBOND®traffic success story by gaining approval. DIBOND®traffic now satisfies the stringent requirements of the German national standard quality mark RAL-GZ 628 as well as the European standard EN 12899-1, confirmed by the in depth report issued by the German Federal Highway Research Institute (BASt) and the German Federal Ministry for Digital and Transport (BMDV).



  • Weight advantage – A “get in lane” traffic sign in the format 1250 x 1600 mm, including edging profile and reflective film, for example, reveals the difference. The total weight of the solid aluminium version = 23.2 kilograms; the DIBOND®traffic sign = 16 kg – that is 7.2 kg lighter! For this application DIBOND®traffic is 31 % lighter!
  • Weight reduction has a positive impact on both handling during the manufacturing process and installation on site.


  • DIBOND®traffic has been approved by the GVZ e.V.(German quality auditing commission for road traffic signs and transport facilities) based on detailed expert reports relating to European standard EN 12899-1 and RAL quality mark (RAL GZ 628).
    The conditions set out in the approval document issued by the German Federal Highway Research Institute (BASt) and the German Federal Ministry for Digital and Transport (BMDV) confirm the equivalence of DIBOND®traffic with conventional road traffic signs.

  • The high-quality coating on the reverse of DIBOND®traffic and lamination of all standard reflective films on the substrate have been tested by StrAus-Zert (Association for testing, monitoring and accrediting street furniture) enabling unrestricted use of DIBOND®traffic for traffic signs.


  • The Environmental Product Declaration (EPD) for aluminium composite panels confirms low energy consumption, low levels of greenhouse gas emission (CO2) and optimised water consumption – 40 % less global warming potential when recycling is taken into account (Comparison: 3 mm solid aluminium / 3 mm DIBOND®traffic with 0.5 mm cover layers).
  • Transport advantage – lightweight DIBOND®traffic, means considerably more traffic signs can be transported than solid aluminium.
  • As a member of the A|U|F e.V., we support closed loop aluminium recycling management for ecological and resource conserving reuse and recycling. The material remains within the European Community and its recycling system.


  • Less expensive panel material in comparison with solid aluminium.
  • Efficient processing: Component parts can be attached using cost-effective punch riveting and adhesive technologies.
  • Energy-saving processes such as routing or punching facilitate contouring.

Sound barrier walls


When appearance is important, CRYLON® Sound Barrier Wall (SBW) and PERSPEX® XT Sound Barrier Wall (SBW), both made of transparent acrylic sheet (PMMA), are the ideal choice, thanks to high levels of transparency, durability and UV stability. The superior quality surfaces also feature very good resistance to weathering and ageing. CRYLON® SBW and PERSPEX® XT SBW provide unimpeded views of the surroundings due to their optical properties and a high degree of transparency. In comparison with conventional materials such as concrete, CRYLON® SBW and PERSPEX® XT SBW are significantly lighter, a real benefit which makes the whole construction process easier. In addition, the materials also look more attractive, avoid the creation of solid division and the wide range of colours and finishes presents aesthetic options.

The CRYLON® SBW Soft Tone and PERSPEX® XT SBW Soft Tone versions feature a matt surface, which is achieved by a special co-extruded coating on one or both sides. The satin matt finish on the surface avoids reflective effects, improves light scatter, and in so doing enhances the sound barrier’s function.

Both CRYLON® SBW and PERSPEX® XT SBW, and variations of these materials, have been tested and approved in accordance with European standards EN 1793 and EN 1794 and comply with the German technical regulation ZTV-Lsw06. They comply with the requirements regarding acoustic insulation, fire behaviour, and strength under wind loads as well as resistance to stone impact.


IMPEX® stands for a broad range of large-scale, extruded polycarbonate sheets which are practically unbreakable and offer outstanding visual and mechanical features. The top quality sheets are characterised by very high impact resistance. Co-extruded UV protection layers on both sides of IMPEX® sheets provide excellent weather resistance for sound barrier walls.

The IMPEX® HC version stands out not only because of its UV protection but also due to an abrasion resistant coating on one or both surfaces. This makes the sheets less sensitive against scratches, more resistant to numerous chemicals and solvents, and ensures long-term durability in harsh road traffic environments.


Recycling system for aluminium composite panels in Germany

We are the first manufacturer of aluminium composite panels in Europe to have established a recycling system for the return of our aluminium composite materials in Germany. Collecting and recycling the material is carried out in cooperation with our strong partners in the A|U|F. This association of German metal construction companies, system houses and other companies, organizes a closed-loop recycling system to deal with the aluminium used in the window, door and façade sectors.

Initially, the option of returning our aluminium composite panels will start in Germany and will soon be extended to include other European countries and other products. If you are interested in collaborating with us, please get in touch with your known 3A Composites contact or send us a message.
