Frequently Asked Questions
Aluminum offers superior corrosion resistance and lighter weight (⅓ steel density). Steel provides higher stiffness for tall walls > 6 ft. Choice depends on span and exposure. For homes < 5 ft flood height, aluminum is preferred.
Steel averages 20–25 % cheaper per sq ft but requires galvanizing and repainting. Aluminum's lower maintenance offsets higher initial cost after 5 years.
No—they oxidize to a protective layer. Periodic rinsing removes salt deposits. Reference hardware corrosion control.
Yes—hybrid frames (steel posts + aluminum panels) balance weight and strength. Ensure isolation pads to avoid galvanic reaction.
Steel has 2× impact resistance, making it ideal for vehicular barriers. Aluminum deflects elastically but returns to shape under design limits.
Yes—both can be engineered to ASCE 24 and FEMA TB-3 standards with proper coatings and documentation.
