Railing C bed frame with drawers 3D print model

The typical deck railing is generally built from pressure treated lumber. Posts on a deck are also typically pressure treated wood and standard sizes are 4x4, 6x6, and 8x8. These posts give structural support to the railing assembly and are the most critical part for the safety of the guard rail assembly.[15] In between the posts, two 2x4s are attached to the posts with screws for the best connection. The lower board is placed 3.5from the top of the finish deck to the bottom of the board. The top board is placed with the top at 35 from the deck. Then the vertical 2x2 pressure treated wood balusters are installed spaced regularly every 3.5". Then a 2x6 is installed horizontally across the top of the posts and to 2x4. The 2x6 should be fastened with screws to the posts and 2x4 boards for the most rigidity.

Mountain laurel handrail, glass baluster systems, metal baluster systems, and composite railing systems all install in a similar manner. The differences is in the type of baluster installed. All four of these deck railings can be built using pressure treated lumber, another wood like cedar, or composite lumber to provide the structure.

Wrought iron and other metal railing systems that do not come in ready-to-install kits will usually require a skilled blacksmith as much welding will be required. These sections are typically built off-site in a workshop under controlled conditions, so that installation on the job site can be as speedy as possible.
