No End-Cut Field Treatment Required

Unlike pressure-treated lumber, OC composite framing needs no end-cut preservative after cutting, rot and pest resistant throughout its full cross section.

Follow Manufacturer Fastener Specifications

OC Lumber does not corrode hardware, but always confirm connector coatings are rated for exterior framing environments on Missouri outdoor deck installations.

Cap Notched Posts Correctly for Multi-Ply Beams

When notching posts, follow OC notching guidelines and use three No. 10 x 4-inch screws to secure 3-ply beams to 6x6 OC Structural Composite Posts.

Check Local Building Codes Before Installation

Always verify Missouri permit requirements, span ratings, and post height limits, maximum post height is 14 feet above grade, before framing any deck structure.
