CHOOSE THE RIGHT FIXINGS FOR YOUR EXTERNAL DECKING PROJECT
Corrosion is the biggest threat to the performance of outdoor metal fixings – its consequences range from unsightly stains on the surface of wood to the loss of load bearing capability and premature failure . As the deterioration of a deck fixing is often unseen , failures can occur without any warning causing the safety of the structure to be compromised .
Sourcing for your next decking project ?
Look for the Mark
Recommended fixings for timber deck boards * Screws provide a number of advantages over nails – they are unlikely to lift if movement occurs ; are more easily removed to allow access ; are less likely to be damaged during installation and hammer dents on boards are avoided .
Specialised decking screws are available which include features such as : self-drilling threads and self-countersinking heads . All fixings should be between 2-3 times the length of the board thickness ( unless the fixing manufacturer can substantiate any different ). On hardwoods or dense species softwoods , the use of screws is always recommended – predrill pilot holes with 2mm oversized clearance and countersink slightly below the surface .
Find third-party verified and fit-for-purpose products and installers
From deck components and design engineers to wood coating solutions and specialised fixings .
To retain the aesthetic of the surface there are several ‘ secret fixing ’ systems on the market . Fixings can be inserted diagonally into the sides of the board with specialised tools ( if board depth is sufficient ) or clip systems offer alternative concealment methods .
* Specialist fixings are used with wpc products - usually available from the deck product supplier . These include ‘ secret ’ fastener clips and colour matched trim fixings . Always follow the manufacturer ’ s installation instructions .
