Can I fix to steel joists or frame?
This practice is not always successful because the screws normally provided are not suitable for fixing timber to steel. During periods of higher humidity, the expanding timber may cause the screws to fail in shear. It is recommended that the decking boards be nailed or screwed to a timber batten affixed above \ or beside the steel joist.
Should I finish the deck with anything?
As a minimum, a protective coating should be applied to all surfaces (including any freshly cut end) of each decking board, preferably before fixing to the joists. A protective coating includes products which penetrate the surface of the timber and products which provide a film or coating to the surface of the timber. This protective coating of the timber surface will minimise the effects of weathering of any timber (treated or untreated) in an exposed situation.
The purpose of the protective coating is to slow down the rate at which the timber will take up or lose moisture. By slowing that rate down, the severity of any checking is considerably reduced. The coating should contain a fungicide to prevent mould growing on any sugars or starches that may be in the coating.
Most timbers contain water-soluble extractives which provide colour and some decay resistance to the timber. Discolouration from these water-soluble extractives will be leached to the surface of the timber whenever moisture leaves the timber. Because the discolouration is water-soluble, it can be washed to other surfaces and leave an unsightly stain which can be difficult to remove from brickwork and concrete. To lesson the likelihood of such staining, use seasoned timber and apply a protective coating to all surfaces (including any freshly cut ends).
Iron or Steel staining
Avoid using any tools which may deposit fine iron filings on the timber surface. Any iron filings which are not cleaned from the surface are likely to create unsightly black staining of the timber. An angle grinder cutting bricks creates iron filings from the metal mesh which forms the base of the cutting disk.
Some softwood species such as radiata pine and slash pine can be prone to resin bleed. Only some boards are affected. If a board shows obvious signs of resin bleed then don’t fix it in the deck. If it has to be fixed in the deck, fix it in a position where the resin bleed won’t be a problem. Sometimes it may not be obvious that a board is prone to resin bleed until after the finished deck has been exposed to a period of hot weather. In such circumstances the resin can be cleaned up or the offending board replaced.
Can your timber shiplap cladding and decking be used in Bushfire Areas?
Yes we have a range of species that are approved for use in bushfire areas, up to Bushfire Attack Level – BAL29. AS 3959 – 1999 Construction in Bushfire Prone Areas, permits fire-retardant-treated-timber to be used in certain bushfire prone areas where the use of timber externally is otherwise not permitted. Included in the definition of fire-retardant-treated-timber are timber species which meet specified parameters without having to be subjected to a fire retardant treatment. A number of species have been tested.
– Seven Hardwood species have been shown to meet the parameters. They are —Blackbutt, Spotted gum, Red ironbark, Turpentine, River red gum, Silvertop ash and Merbau.
