MicroPro® Treated Lumber
Lumber

MicroPro® technology is a revolutionary way to pressure treat wood for decks, fences, landscaping and general construction uses. MicroPro pressure treated wood is treated with micronized copper preservatives, which help protect against termite damage and fungal decay. MicroPro offers many benefits including significantly improved corrosion performance. MicroPro treated wood products are US building code compliant.

Pressure treated wood products with MicroPro® technology might be branded as LifeWood MCA, ProWood Micro, MicroPro AC2, to name a few.

General Use - Above Ground (Examples - decking, joists, beams, and sills.)
 
Ground Contact and Fresh Water Contact (Examples - decks, fence posts, playsets and docks.)
 
Ground Contact - Critical Structural Members (Examples - building poles, permanent wood foundations, salt water splash zones.)
