Balconies / Event Flooring

Our TERRAZZA MAXI panels combine light weight, robustness and weather resistance – providing the ideal foundation for durable balcony decking and versatile event flooring. Their high load-bearing capacity and structural stability ensure safety and comfort even under intensive use.

Slip-resistant surfaces provide additional safety in everyday use as well as at events, while easy handling and fast installation allow for flexible applications – from temporary event areas to permanent residential solutions.

Thanks to their resistance to weather conditions and moisture, the panels remain dimensionally stable and low-maintenance even in outdoor environments. This results in a sustainable solution that perfectly combines functionality, aesthetics and economic efficiency.

Project insights

Creating sustainable innovation together

Frequently asked questions about us and our products

What is Design Composite’s approach to sustainability and circularity?

Sustainability is part of our DNA.
We focus on resource-efficient alternatives, already use 95% renewable energy (Scope 1 & 2), develop recyclable mono-material composite elements, and continuously increase the share of recycled materials in our products.

Can the elements be processed by the customer?

Yes. The panels can be easily cut, drilled, milled, riveted or bonded.

Which bonding methods are used?

Depending on the requirements, we use hot-melt PU adhesive systems, two-component PU adhesives, or directly weld thermoplastic products together.

Can plywood panels be replaced by lightweight solutions?

Yes. TOP-air antislip provides a durable, moisture-resistant alternative that reduces weight by approximately 50–60%, depending on the panel thickness.

Can ready-to-install elements be ordered?

Yes. Thanks to our extensive service facilities, we also supply elements ready to install.

Is recycled material used?

Yes. The core consists of 100% recycled PET foam.

Can GRP surfaces be repaired?

Yes, repairs are generally possible. Suitable repair instructions can be requested directly from Design Composite.

Which formats are available?

Standard formats are available up to 6,000 × 2,450 mm. Custom made formats of up to 13 m in length and 2.90 m in width can be manufactured on request.

How should the elements be stored?

The elements should be stored flat on pallets in an indoor storage area. High point loads must be avoided.

Are inserts or special cut-outs possible?

Yes. Inserts such as wood, aluminum profiles, PVC or PET rigid foam can be integrated. Custom formats and special cut-outs are produced using our CNC machining centers.

How can the surfaces be cleaned?

Information on suitable special cleaning agents is available directly from Design Composite.

Is Terrazza Maxi certified by the German building authorities?

No. Terrazza Maxi does not have an official building authority approval in Germany.

Can you supply the required installation materials for panel installation?

Yes. We would be happy to prepare an individual offer for this.

Can expansion joints be installed between the supporting beams?

What is the function of the support tape?

The support tape is used to define the adhesive height, compensate for tolerances and interrupt sound bridges. The support tape must always be used.

Is it always necessary to use a primer when bonding?

In principle, a primer always improves the subsequent bonding and, in some cases, makes bonding possible in the first place. For all applications, always use Collano HP 1000 primer.

Can TERRAZZA MAXI ECO also be fixed from below using wood or sheet metal screws?

No! The thin face sheets and the panel core are not suitable for direct screw fastening. Without special factory-installed inserts, only cavity fastening systems are suitable.

What materials is the surface made of?

Polyester reinforced with glass fibers (GRP).

Is it possible to reduce the expansion joint width between profiles to less than 14 mm?

No. In order to absorb stresses, joint sealants require sufficient width and depth. Because larger joint widths are better able to accommodate panel movement, each joint must be designed with a minimum width of 14 mm between the two connection angles for panel lengths of up to 6,000 mm.

How much Collano A 1970 sealant is required to fix the edge finishing angle or the connection angle?

Approx. 5 linear meters of bonding per adhesive cartridge. Collano HP 1000 must be used.

How much Collano A 1970 adhesive is required to bond the panels to the substructure?

Approx. 5 linear meters of bonding per adhesive cartridge. Collano HP 1000 primer must be used.

Can the surface and the white backside be painted?

Only with suitable coating systems. Please consult your paint and coating supplier. Custom solutions are available on request.

What is the function of the PE backer rod in the joints?

The PE backer rod is used to limit the joint depth and to prevent three-sided adhesion.

Can a charcoal grill or similar equipment be placed on TERRAZZA MAXI panels?

For fire safety reasons, we advise against placing charcoal grills, fire pits, terrace fireplaces or similar equipment on the panels. Any such use is at the user’s own responsibility. We recommend using a suitable protective base, for example made of stone or glass.

Can a railing or balustrade be screwed directly onto the panels?

In principle: no. However, professional fastening may be possible using suitable metallic inserts, sleeves or similar components.

What happens to any remaining adhesive or sealant?

Collano A 1970 adhesive is solvent-free and is therefore suitable for a wide range of applications in the construction, industrial and automotive sectors.

Is it possible to use alternative sealants and adhesives?

The Collano products have been tested and proven to be optimal. Professional installation in accordance with our guidelines is required. The use of alternative products is at the installer’s own responsibility.

Is it possible to use an alternative support tape?

This product has been tested and confirmed as optimal. The high strength of the support tape enhances immediate walkability. The use of alternative products is at the installer’s own responsibility.

Can TERRAZZA MAXI ECO panels be processed on-site by the customer?

Yes, provided suitable tools and machinery are used. Trial processing should always be carried out in advance.

Sustainability & ESG – Innovation for a Future-Ready Economy

Sustainability & ESG

The location of our company inspires the entire team every day to actively contribute to reducing environmental pollution. Surrounded by unspoiled mountains and meadows, design composite relied on state-of-the-art ecological construction methods when building its new production facility in the Salzburg region of Pinzgau.
The measures implemented have resulted in a positive energy balance and enabled the sustainable reduction of a calculated CO₂ emission equivalent of 140 tons per year.

For us, sustainability is more than a goal – it is an integral part of our corporate strategy.
Through innovative technologies, a responsible supply chain, and a clear ESG focus, we develop sustainable solutions that meet the requirements of tomorrow.
