6mm Decking Spacers 4 Pack

Product Information

If tackling your project alone:If you are working without an assistant to help you nail the hanger into place, use your pencil or chalk tomark where the top of the first joist hangeriswhen using the scrap wood. The shape and size of the deck influence the layout and number of joists, potential spans, and even the spacing. Treated- Treated timber is suitable to be used externally and is suitable for wet areas or areas where the timber will be coming into contact with the ground. When you are planning the construction of a new deck, the deck joist material is a crucial factor to keep in mind while determining the joist span and spacing. But before we get onto that we need to explain why you need to plan your decking with the right joist spacing.

If the deck will have a diagonal layout, then reduce the spacing to account for the additional distance the boards must cross between joists. We also recommend using joist tape or a wood protectant to help shield cut ends from moisture damage. Chapter 5 of the 2018 ICR has a variety of tables that are full of useful information about minimum footing sizes (R507. on NZS3604, the M12x250 coach screw is wrong (the size doesn't exist), but the text in the document is correct.

The Codes identify maximum joist and beam span requirements for different wood types to ensure decks don’t sag or collapse under the weight of people or snow load. Eco friendly, water resistant, low maintenance and fire rated wood plastic composites designed to look and feel like real wood.

As strong, versatile and cost effective this grade of timber might be, it does have some defects, such as grain deviations which may affect the strength of the timber as well as some cosmetic defects such as sap stains and sometimes and an uneven surface. Place a scrap piece of decking joist material in the joist hanger to set the width and then nail or screw the joist hanger on the inside of each double beam every 400mm.

The location of the deck is also necessary to consider when you are planning this construction project. If you are laying your deck on a non-concrete surface, such as grass or clay, lay the framing on patio slabs for additional stability. The spindles are held in place simply by fixing the infill strips between each spindle in both the top and bottom rails. Just keep in mind that the more elaborate the decking plan, the greater the joist structure requirements. You can run a string across the deck frame during the construction process to ensure the joists are level.

However, a wider joist can also be used to increase the span or to use wider spacing between the joists. Base the width of your deck joists on how far apart the beams are or the distance between the beams and ledger. Fixed and adjustable composite decking pedestals supports can be used to facilitate the installation of decking on a range of different surfaces, including balconies, podiums and roof decks.

The higher the deck, the greater the need for post and beam support, and the shorter the joist spacing and spans. NZS 3604 also outlines many other requirements on joists such as fastenings, please refer to this document for more information. Deck joist span tables commonly identify the maximum span for different wood types and joist spacing.
