For your deck or composite deck in Quebec, the stability of the support is essential. Although steel is rarely favored in residential construction due to its cost and installation complexity, it offers unparalleled robustness when properly implemented. Discover how to choose and install 4.5” diameter steel columns to ensure the longevity and safety of your outdoor living space.
Why opt for steel for your supports?
Steel columns remain a popular option in certain premium projects. Thanks to their mechanical resistance, they are perfectly suited for decks exposed to heavy loads or areas where freezing and thawing can intensely stress the structure. Even if steel is more expensive and less available than wood or composite materials, it guarantees durable and stable load-bearing capacity.
Types of structural steel columns
Round steel structural columns with welded top and bottom plates are generally used. The most economical version is the 4.5” diameter round column, with a 1/8” wall thickness. These columns are often part of decorative sets offering both aesthetics and structural performance.
- 4.5” Round Column: Optimal diameter for combining controlled cost and mechanical resistance. 1/8” wall thickness suitable for residential loads.
