Yes, carbon fiber straps are generally more affordable than steel I-beams.

According to the repair method comparison, the two solutions differ in both material and installation requirements:

• Carbon Fiber Straps: These are categorized as having a moderate material cost. They are a faster, less invasive solution typically used for moderate bowing and can be installed in just 1–2 days.
• Steel I-Beams: These carry a higher material cost. The installation process is also more intensive and slower because it requires excavation, though it is noted as being excellent for severe structural issues.

While carbon fiber offers a more budget-friendly and lower-impact approach for moderate damage, the best choice depends on the severity of the wall displacement.
