As the popularity of outdoor living spaces continues to grow, so too does the need for an up-to-date understanding of Ontario Building Code Deck Span Tables. Decks are a great way to add an additional living space to your backyard, but they can also be dangerous if not built correctly. Knowing the specific requirements for deck spans in Ontario is the first step in making sure your deck is built safely and to code.
The Ontario Building Code (OBC) outlines specific requirements for deck span tables to ensure safe construction of decks in the province. Deck beams and joists must be able to carry the weight of the deck and any people or objects that may be placed on it. The OBC provides different span tables for different types of decks, depending on the materials used and the size of the deck. In order to ensure your deck is built safely, it’s important to understand the different span tables and how they apply to your project.
The most common type of decking material in Ontario is pressure-treated lumber. Pressure-treated lumber is a wood that has been treated with a chemical preservative to make it more resistant to rot, decay, and insect infestation. It is the most economical option for deck construction, but it does have some drawbacks. For example, pressure-treated lumber is not as strong as other types of decking materials such as cedar or composite. This means that the deck beam and joist spans must be shorter than with other materials. The OBC provides a specific span table for pressure-treated lumber decks, which details the maximum span allowed for different sizes of beams and joists.
When constructing a deck with a more exotic material such as cedar or composite, the OBC provides different span tables for these materials. Cedar is a more expensive choice than pressure-treated lumber, but it is much stronger and more durable. This makes it possible to achieve longer spans with cedar decking than with pressure-treated lumber. The OBC provides specific span tables for cedar decks, which detail the maximum allowable span for each size beam and joist.
Composite decks are becoming increasingly popular in Ontario, due to their low maintenance requirements and unique appearance. Composite decks are typically constructed from a combination of plastic and wood fibers, and they are much stronger than either wood or plastic alone. As such, the OBC provides specific composite deck span tables that allow for longer spans than with either pressure-treated lumber or cedar.
No matter what type of deck material you choose, it is important to understand the Ontario Building Code Deck Span Tables and make sure that your deck is built safely and to code. By following the correct span tables for your decking material, you can ensure your deck is built to last and will provide years of enjoyment.
