Is it possible to vary the deck size to use standard steel members?

Yes, you can vary your deck size to make use of standard steel members, leading to potential cost savings and improved structural efficiency. Standard steel beams like I-beams and wide-flange beams come in specific sizes and weights—for example, I-beams commonly range from 3 inches (5.7 pounds per foot) to 24 inches (121 pounds per foot), with standard lengths up to 60 feet .

Designing your deck around these standard sizes can help minimize custom fabrication needs, reducing both material costs and construction time. It also ensures your project aligns with established structural standards, supporting safety and durability.

However, it’s important to consult with a structural engineer to make sure the chosen steel sizes and overall deck design meet your specific load requirements and comply with local building codes.
