Sustain Lumber

Sustain lumber is becoming increasingly popular due to the fact that it can withstand many weather conditions. With its natural color and easy paint-ability, sustain lumber is very versatile for both commercial and residential uses.

With sustain lumber the chances of corrosion decreases exponentially. This lumber can be used for interior and exterior above ground, ground contact, and fresh water immersion. With a wide range of uses, sustain lumber is the lumber of choice for your next building project.
