The size and spacing of beams depend on the deck's dimensions, local building codes, and decking materials. Cedar decking is a popular choice due to its natural resistance to rot, decay, and insect damage, offering a longer-lasting and low-maintenance decking material option. Typically made from treated wood or steel, beams are positioned parallel to the house, often below joists, and secured to prevent sagging. Regular inspection for damage and level installation are vital to maintaining structural integrity. Beams work in conjunction with other structural components like posts and footings to ensure that the deck is not only functional but also safe and durable. Implementing connectors and hardware, such as steel connectors, is crucial to secure beams and girders properly. Compliance with building codes is imperative; consult local authorities to fulfill all support elements' requirements for safety and durability.
Determining Joist Requirements
When constructing a deck, determining the correct joist requirements is essential to ensuring structural integrity and safety. This involves careful consideration of several key factors:

- Considering Material and Load: Wood type greatly influences spacing due to varying strength; stronger wood supports wider spacing. Additionally, the expected load, including guests or equipment like hot tubs, impacts joist requirements. Proper joist selection and installation are crucial for floor safety and performance. For decks that are elevated, the position affects the necessary support posts and beams required. It is also important to seek guidance from licensed deck construction professionals who understand the nuances of structural requirements.
- Joist Sizing: The joist width can be calculated using the formula (Joist Span ÷ 2) + 2. Double thickness nearly doubles the possible span.
- Compliance with Codes: Always adhere to local building codes for sizes and materials to maintain structural soundness.
