Follow these five straightforward practices for a safe, code-compliant Owens Corning Composite Lumber installation on Missouri deck projects.
OC Composite Lumber cuts just like wood, no specialty tools needed, making cuts faster and more precise on every Missouri job site.
Unlike pressure-treated lumber, OC composite framing needs no end-cut preservative after cutting, rot and pest resistant throughout its full cross section.
OC Lumber does not corrode hardware, but always confirm connector coatings are rated for exterior framing environments on Missouri outdoor deck installations.
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.
Always verify Missouri permit requirements, span ratings, and post height limits, maximum post height is 14 feet above grade, before framing any deck structure.
Whether you are a Missouri homeowner or contractor, Owens Corning Composite Lumber gives every deck build a rot-proof, rust-proof foundation built to last. Contact Top Deck today for pricing and availability.
