Material Considerations

• Steel: High tensile strength, ideal for heavy-duty applications; hot-dip galvanized steel offers excellent corrosion resistance.
• Aluminum: Lightweight, corrosion-resistant, and non-magnetic, suitable for outdoor or sensitive electrical environments.
• Stainless Steel: Best for highly corrosive or hygienic environments, such as chemical plants or food processing facilities.
• Reinforced Concrete: Used for permanent, high-load support in large-scale infrastructure projects, though less common due to installation complexity .
