Grad® : traditional method

The grad® system comes as an aluminum track (also called rail) pre-fitted with our grad® clips. 

 

Grad® clips are not made of your traditional plastics. 

Polyoxymethylen (or POM) is an engineering thermoplastic that is often used in the production of ski boots. With great dimensional stability, high mechanical strength and rigidity, corrosion resistance, toughness at low temperature (down to 40 C = 40 F), excellent resistance to moisture, gasoline, solvents and many other chemicals of neutral pH. grad® clips can be used across a wide temperature range (up to +90 C = +195 F). 

POM is a favorite across many fields in the construction industry and is recyclable.

Why are clips pre-set onto an aluminum track? What does it mean? 

 

Traditional decking installations use individual clips every 16” that need to be fastened one at a time along each board to secure the deck.  

With grad® the clips are already there and in the right spot, there is no need to use individual clips anymore.  Boards are simply snapped on the clips so you don’t need to fix boards with screws.  

 

Installation is fast, easy, straight-forward, and leaves no margin for errors.

How to use grad® rails?

Rails are to be fastened onto structural  elements (studs, beams, concrete floor…). The type and number of required fasteners depend on the substrate and the wind zone. Check our installation guide for more recommendations.

Rails must be parallel to each other (simply use a level) and the clips from one rail to the other must be aligned. There is no need to use one rail per board! Use rails just like you would use 2x joists.  

 

The system is for different applications:

— narrow boards

— wide boards

— breaker boards

— picture frames

— elevated decks

— platform decks

What type of deck can I build? 

 

 

— standard deck

— docks or boardwalks

 

 

What surface can I build onto?:

 

 

— use rails over joists of a brand new deck frame or an older deck frame*

— directly over concrete floors*

— directly over old slabs or tiles*

 

 

 

  • *always follow installation guidelines and local/state/federal building code standards 

How to use grad rails with a deck frame?

 

MINI RAILS AND START RAILS MUST BE LAID OVER JOISTS, PR39 CAN BE USED AT 90° ACROSS JOISTS

 

— Rails are fastened onto joists

— Deck boards are snapped over the clips

— Enjoy the results!

— No need to fasten individual clip s anymore

— Build well and faster with minimum effort 

 

Make sure the deck frame is sound and meets standard local/state/federal building code expectations. Check our installation guide for more details.
