What is the primary advantage of using plastic tipped chairs?

• A. Prevent corrosion
• B. Increase weight
• C. Lower cost
• D. Hard to install

Answer: (A)

Using plastic tipped chairs mainly provides corrosion resistance. Plastic tips are non-corroding, so they won’t rust like metal tips can when exposed to moisture, de-icing salts, or aggressive concrete mixes. This helps keep the chair supports stable and prevents rust staining or corrosion-related deterioration of the embedded reinforcement and surrounding formwork. The other options don’t address this durability benefit—plastic tips don’t inherently increase weight, they aren’t primarily a cost-saving measure, and they don’t make installation harder.
