Rebar

Basics

• Shorthand for reinforcing bar
• Beams added to concrete to add tensile strength
• Typically steel, although new material options are being explored

New Material Options

• Epoxy Spray Coated Coated Steel was tried, but supposedly lead to small scratches/defects leading to concentrated corrosion, and then breaks in that point
• Not to be confused with a proper liquid epoxy coat, which may be more stable, also combination with other methods
• Galvanization
• Stainless Steel (not likely due to cost)
