Handrails are calculated with the newel posts at 2m centres. You will need to add one newel posts for every time there is a gap in your total length. NZS 3604 also outlines many other requirements on joists such as fastenings, please refer to this document for more information. Galvanized hanger nails:You need 1 1/2″ joist hanger nails. Joist hanger nails are hot-dipped and galvanized. Be sure you have enough nails on hand to fill each hole on every hanger.

The joists may be cantilevered at each end beam or terminate flush with the end beams. Joists that cantilever allow for the use of longer joists than those that terminate at the outside face of the beam.

A scrap piece of lumber:Cut a piece of wood from your pressure-treated joist lumber to use as a guide when placing your joist hangers. Make sure the scrap wood is in the same dimensions as your joists. For example, if you’re using southern yellow pine lumber for your joists, the allowable cantilever overhangwould be 3′ for 2-by-10 joists spaced 16″ apart and spanning 12′ total.

Beam Configuration – Ledger to Beam, Free Standing (joists resting on beam), or Joist Hangers (joists attached to beam sides with hangers) I agree with the 400 centers, but how would you solve my problem? Do you think stepping it is the way to go, sort of the same way you would lay laminate flooring in the house. My drawing are nearly done so these maybe make it easy to see what i have. C16 Timber: C16 is the most commonly used form of timber. It can be used in many different applications and is the most cost effective option. C16 timbers are kiln dried to minimise the amount of moisture in the wood. This grade of timber which is commonly used in internal construction such as floors, walls and roof joists is not only cost effective, it has the strength and other properties such as bending, compression and density which are required for construction. 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. Once each hanger is installed evenly and nailed into place, you can begin attaching your joist boards: A bubble level:If you’re working alone, a bubble level will help you measure straight lines when installing joist hangers.

are required are given in 4.8m lengths so there is as little joins as possible. All screws are supplies. The 2018 IRC is a good place to start as is your local Code which may adjust values or loads for regional conditions. Joist Spans for #2-Grade Dimensional Lumber Four very popular types of spindle are usually used the Square, Chamfered, Colonial and American and each of them can be installed using a universal hand/base rail shown here. The spindles are held in place simply by fixing the infill strips between each spindle in both the top and bottom rails.
