MicroPro® Fastener and Hardware Information
MicroPro® technology offers many benefits including significantly improved corrosion performance. Smart Sense® pressure treated lumber and other wood products, with MicroPro® technology exhibits corrosion rates on metal products similar to CCA pressure treated wood and 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 MicroPro® treated lumber and other wood products used for interior uses 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, MicroPro® treated lumber and other 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, MicroPro 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 MicroPro® treated wood used in ground contact applications or when MicroPro® 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. Contact Osmose for further information on aluminum contact use in commercial, industrial, and specialty applications such as boat construction.
