Goodfellow Terra® Pressure Treated Wood products, using MicroPro® technology, exhibit significantly improved corrosion rates on metal products, similar to untreated wood.
For interior or exterior applications, use fasteners and hardware that are in compliance with the manufacturer’s recommendations and the building codes for their intended use.
Aluminum building products may be placed in direct contact with Goodfellow Terra Pressure Treated Wood products in interior applications and above ground exterior applications such as decks, fencing, and landscaping projects. Examples of aluminum products include siding, roofing, gutters, door and window trim, flashing, nails, fasteners and other hardware connectors.
However, Goodfellow Terra Pressure Treated Wood products in direct contact with aluminum products should only be used in code compliant construction applications that provide proper water drainage and do not allow the wood to be exposed to standing water or water immersion. In addition, Goodfellow Terra Pressure Treated Wood should not be encased, sealed, or wrapped with aluminum products where trapped moisture or water can occur so as to avoid pitting or other unwanted results.
We recommend you contact the aluminum building product manufacturer for their recommendations regarding their aluminum products in contact with Goodfellow Terra Pressure Treated Wood used in ground contact applications or when Goodfellow Terra Pressure Treated Wood is exposed to salt water, brackish water, and chlorinated water, such as swimming pools or hot tubs.
Also check with the aluminum product manufacturers regarding compatibility with other chemicals and cleaning agents.
