Composite decking manufacturers

Nine patented fixing technologies since 1995

Exterpark registered its first concealed fixing clip, Exterpark Classic, in 1995. Shark is the ninth registration in that programme, and each generation answered something the previous one left open: composite boards arriving with an expansion coefficient that timber clips were never designed for, aluminium joists imposing tolerances a batten clip could not hold, rooftop terraces making uplift a governing load rather than a marginal one. The full patent history and fixing technology is documented separately.

In the screwless version, the substructure uses aluminium joists, which stay straight and will not warp or decay; the screw-in version is installed on timber joists. The invisible profile keeps the fixing hidden while maintaining a 4 mm drainage channel, so water drains and air circulates without the deck reading as a slatted surface.

Composite decking made from 95% recycled content

Exterpark Tech boards are made from 95% recycled content:

LEED certifies projects, not products, so no decking board is LEED certified in itself. What this composition provides is a documented attribute a project team may use to support specific credit pathways in its own application. Architects should confirm eligibility during specification rather than assume automatic qualification. More on our green practices.

Independently tested by three laboratories

A patent registration establishes that a design is original. It says nothing about how that design behaves once it is carrying a deck.

Exterpark’s fixing systems have been assessed by three independent bodies: AIDIMME, Tecnalia and Applus. The tested results include two million impact cycles, an operating range from -40°C to +90°C and load capacity above 4,000 kg/m².

The relevant point for a specification team is the scope rather than the figures: board, clip and substructure are evaluated as one functional system, which is what the specification document actually describes. Test documentation is available on request for inclusion in specification files and tender submissions.

Six composite decking collections

Exterpark Tech is available in six collections, all installed with the Shark system and suitable for residential, hospitality, commercial and public projects. The choice depends on the finish, texture and colour the architect has in mind:

The NEXUS collection has been installed at Go Park, Hong Kong, demonstrating its use in a demanding, high-traffic public environment. NEXUS has also been used, together with SUPREME, at Marsa Al Arab, Dubai, one of Exterpark’s most recent flagship projects. See more completed installations in our project gallery, or explore our Bamboo and Wood collections for alternative natural decking systems.

Who manufactures Exterpark Tech composite decking?

Exterpark Tech is manufactured by Exterpark, a Spanish decking company founded in Barcelona in 1977 that patented the first hidden fastening clip for decks in 1995. Its decking and fixing systems are present in more than 80 countries.

How does the Shark system work?

Shark is the patented fixing system developed by Exterpark. It secures the decking boards with an invisible profile, keeping every screw and joint hidden beneath the surface. It’s available in screw-in and screwless versions.

What makes the Shark system different from conventional decking installation?

Conventional systems leave screws or joints visible on the surface. Shark hides all fixings beneath an invisible profile and allows a single board to be removed without disturbing the rest of the deck.

What is the invisible profile?

The invisible profile is the part of the Shark system that conceals every fixing beneath the decking surface, so no screws or joints are visible when walking on the deck. It also leaves a hidden 4 mm drainage gap: water drains away and air circulates, but phones, coins, rings and other valuables cannot fall through and get lost under the deck, and heels do not get caught.

Is the Shark system installed with screws or without?

Both options are available: screw-in and screwless. The choice can be adapted to the requirements of each project.

What is Exterpark Tech composite decking made from?

Exterpark Tech boards contain 95% recycled material: 65% reclaimed FSC®-certified bamboo and wood fibre, 30% recycled PE and 5% additives.

Is Exterpark Tech suitable for commercial and hospitality projects?

Yes. Exterpark Tech is designed for residential, hospitality, commercial and public-space applications, with six collections to choose from according to the finish and texture each project calls for.

Can individual Exterpark Tech boards be removed after installation?

Yes. The Shark system allows individual boards to be removed and replaced without dismantling the surrounding decking, simplifying maintenance and access. This is the principle behind accessible decking systems.

Can Exterpark Tech contribute toward LEED credits?

Its recycled composition can contribute toward LEED credits on qualifying projects. Requirements depend on the specific project and certification criteria, so technical documentation should be reviewed during specification. See our LEED-related materials.

Which laboratories have tested Exterpark’s fixing systems?

Three independent bodies: AIDIMME, Tecnalia and Applus. Testing covers the assembly rather than the board alone, including two million impact cycles, an operating range from -40°C to +90°C and load capacity above 4,000 kg/m².

How many patents does Exterpark hold in fixing technology?

Nine, registered since 1995. The first was Exterpark Classic, the first concealed fixing clip in the sector; the most recent is the Shark system, the ninth.
