The Shark System: Hidden Fastener Decking Technology

Five engineering decisions built around the patented Shark Clip, named Most Innovative Construction Tool at IBS.

Engineered Difference

Why Exterpark Technology Is Different

Exterpark wasn’t built to compete with traditional decking. It was built to replace it. Our system is the result of years of engineering focused on one goal: outdoor flooring that looks better, lasts longer, installs faster, and performs under any condition.

Every component, from the invisible fastener to the aluminum substructure, was designed with purpose.

Meet the Shark Clip

Shark is the patented hidden fastener at the heart of every Exterpark deck (you may know it by its former name, Magnet). It holds each board from below and locks it onto an aluminum joist, so nothing pierces the surface, the joints stay closed and every board remains independent. At IBS, the International Builders’ Show, Shark was named Most Innovative Construction Tool.

How a Shark Deck Goes Together

1. Set the Aluminum Joists

Aluminum joists sit on adjustable pedestals or on the existing base, straight and level. Aluminum doesn’t rot, warp or attract termites.

2. Seat the Shark Clips

Each clip sits on the joist at the board position. Nothing is screwed through the boards, so the walking surface stays clean.

3. Lock the Boards In

The clip grips the side groove of the board from underneath, and the next board closes the joint. Board by board, up to 3x faster than screw-down decking.

4. Lift Any Board, Any Time

Every board is independent. One board comes out for access to what sits below, or for a replacement, and goes back in without touching the rest.

The 5 Game Changers

These aren’t features. They’re fundamental engineering decisions that
define how Exterpark performs.

Invisible profile

No open gaps between boards, no view of the structure below, and nothing for a heel or a set of keys to fall into.
The patented invisible profile closes the joint over the Shark Clip, so the surface reads as one clean plane.

A SUBTLE DIFFERENCE WHICH MAKES A BIG DIFFERENCE

accessibility

Total access for decks, walls and ceilings.
With the Shark tool, any board can be opened and closed again without disturbing its neighbors.

EMBRACE FLEXIBILITY AS ONE OF YOUR BEST ALLIES 

no screws

No drill noise, no screw heads, no rust streaks.
The Shark Clip locks each board mechanically from below: strong enough to hold, flexible enough to open again. It was named Most Innovative Construction Tool at IBS, the International Builders’ Show.

MAINTENANCE FRIENDLY AND VERY GENTLE FOR THE USER

3 times faster

Up to 3x faster than screw-down decking.
No pre-drilling and no screwing through every board: crews seat the clip, lock the board and move on.
Less time on site means lower labor cost and a shorter schedule.

FASTER TO INSTALL. FASTER TO REMOVE.

ALUMINUM JOISTS

Build it on a lifetime foundation.
Choosing the substructure is choosing the foundation. You wouldn’t build your home on mud, so don’t build your deck on soft wood or plastic joists. Aluminum doesn’t rot, warp or attract termites, it stays straight, and it is easy to work with.

STRAIGHT LIKE AN ARROW AND STABLE AS A ROCK

Designed for professionals. Documented for precision.

Exterpark provides complete technical documentation for project specification: CAD details, technical data sheets, installation manuals and videos, and direct support from our technical team. Whether you’re specifying for a luxury residential project or a large hospitality development, we have the documentation you need.

FREQUENTLY ASKED QUESTIONS ABOUT OUR DECKING TECHNOLOGY

Yes. The hidden fastener clip system is standard across Exterpark Wood, Tech, and Bamboo collections.

No special equipment is needed to install: the standard tools deck contractors already use are enough, and the system goes in up to 3x faster than screw-down decking.

Yes. Every Exterpark board can be removed and reinstalled with the Shark tool (formerly called the Magnet Tool), one at a time, without affecting adjacent boards.

Aluminum doesn’t rot, warp, or lose dimensional stability over time. It’s the highest-performing substructure option for long-term decking installations, particularly in coastal, rooftop, and humid environments.

Shark is Exterpark’s patented hidden fastener, formerly known as Magnet. It holds each board from below on an aluminum joist, so there are no screws through the surface and every board can be removed on its own. It was named Most Innovative Construction Tool at IBS, the International Builders’ Show.
