Gamrat WPC Installation Components
Gamrat WPC installation components are the ideal choice for those who value consistency and a perfect fit across the entire decking system. The system is fully integrated – every element, from boards to clips and joists, has been designed to work seamlessly together, ensuring quick, simple, and precise installation. This perfect alignment is the result of thorough compatibility testing, eliminating gaps, looseness, or visible mismatches.
Gamrat WPC accessories are also resistant to weather conditions, contributing to structural stability and user safety. An added benefit is the ease of installation and maintenance – the well-thought-out design makes building your deck intuitive and hassle-free.
WPC joist
Gamrat WPC Joist is durable and weather-resistant structural element designed for the installation of composite decking.
Made from high-quality composite, it offers excellent resistance to moisture, mould, and pests. It provides stability and longevity for the entire structure, enabling quick and precise terrace installation. Water drainage beneath the decking structure is ensured by specially designed grooves.

Aluminium joist
A joist with increased strength and rigidity, recommended for Gamrat WPC boards. It will also work well in installation on suspended structures- e.g. on concrete posts. It enables the construction of the so-called “floating terraces”. It is available in two versions (low and high), so you can adjust the height of the entire structure to your own requirements.

Mounting sets
The set consists of stainless steel clips and screws. We also offer our proprietary mounting clip solution made from high-quality polymer materials. The starter clip is used to fix the first board. Mounting clips allow hidden fastening, ensuring the terrace maintains an aesthetic and seamless appearance without visible screws. Their unique design ensures a stable installation while compensating for board movement caused by temperature changes. They maintain a consistent expansion gap between the boards.
Mounting kits are available in two variants:
| Kit | Number of elements |
|---|---|
| Kit for 2 m² | 3 pcs – starter clips 32 pcs – mounting clips 35 pcs – screws |
| Kit for 10 m² | 15 pcs – starter clips 160 pcs – mounting clips 175 pcs – screws |
Clips can also be purchased individually. The choice of mounting clip depends on the selected type of board and joist. More information is available in the price list (downloads section) and from our customer service department.
Mounting elements for aluminium joists

Leveling elements
Adjustable pedestals are specialised structural components that allow for creating a level and stable surface for composite decking. They are installed beneath the joists, which serve as the base for the terrace. With adjustable pedestals, it is easy to compensate for ground unevenness or correct deformations resulting from the natural ageing of the substrate. This significantly improves the durability and overall appearance of the terrace.
Adjustable pedestals are available in various sizes and are made of lightweight yet durable plastic.
Installing adjustable pedestals is straightforward and can be carried out by anyone with basic DIY skills. Begin by preparing the ground — levelling and stabilising the base. Then, position the joists at the required height and secure the pedestals underneath. Once in place, you can proceed with installing the decking boards.
We also offer additional accessories for terrace levelling. Full details can be found in the price list (downloads section) or via our customer service team.
