Terrazzo screeds can be made from which materials?

Terrazzo screeds can be made from which materials?

• A. Non-ferrous metal only
• B. Galvanized steel only
• C. Both non-ferrous metal and galvanized steel
• D. Wood

Answer: (C)

Terrazzo screeds are used as rigid guides to define thickness and create a straight edge during the pour, so they must be durable, non-porous, and stable in a moist cement environment. Non-ferrous metals (such as aluminum or copper) resist rust and stay true under use, while galvanized steel gives a tough, corrosion-resistant option thanks to its zinc coating. Wood, in contrast, would absorb moisture, warp, and deform, leading to an uneven terrazzo surface. Because both non-ferrous metal and galvanized steel meet the necessary properties, terrazzo screeds can be made from either.
