MicroPro® treated timber offers many benefits over many other preservative technologies including significantly improved corrosion performance.
MicroPro® treated timber exhibits corrosion rates when in contact with metal fasteners and connectors similar to CCA treated timber and untreated timber.
Always use fasteners and hardware that complies with the manufacturer’s recommendations and building regulation for their intended use.
Nails, screws, and other fasteners should comply to Australian Standard AS 3566.2 Class 4 and bolts should have minimum galvanisation levels to AS 1214 Table2.
Connectors, brackets, joist hangers and similar.
High Hazard Zones. These are zones that are up to 10km from a surf coast or up to 1km from a non surf coast or near swimming pools, brackish water etc. In these zones Type 304 or Type 316 stainless steel hardware is recommended.
Other Exposed: Use Z275 or hot dipped galvanised hardware with a coating thickness of 300gsm minimum.
Aluminium building products may be placed in direct contact with MicroPro treated timber products used for interior and above ground exterior applications such as:
Examples of aluminium products include roofing, gutters, door and window trim, flashing, nails, fasteners and other hardware connectors.
However, MicroPro treated timber in direct contact with aluminium products should only be used in code compliant construction applications that provide proper water drainage and do not allow the timber to be exposed to standing water or water immersion.
We recommend you contact the aluminium building product manufacturer for their recommendations regarding their aluminium products in contact with MicroPro treated timber used in ground contact applications or when MicroPro treated timber is exposed to:
Also check with the aluminium product manufacturer regarding compatibility with other chemicals and cleaning agents.
