4" X 4" Batu Deck Post S4S RL

The 4" x 4" Batu S4S Deck Post offers unmatched durability and strength for exterior construction. Batu (also known as Red Balau) is a premium tropical hardwood prized for its rich reddish-brown color, fine grain, and long service life.

This post is surfaced four sides (S4S) for a smooth, uniform finish that enhances both aesthetics and workability. Batu’s natural resistance to rot, decay, and insect attack makes it an excellent choice for exterior applications where longevity and performance are critical.

Ideal for use as deck posts, pergola framing, outdoor railings, and other structural elements, Batu provides a stable, dense, and reliable hardwood solution that weathers beautifully over time, developing a natural silver patina if left unfinished.
