Gate latches must be made of which materials?

• A. Steel
• B. Malleable iron
• C. Aluminum alloy
• D. Any of the above

Answer: (D)

Gate latches are not tied to a single material; the choice depends on the environment and the required performance. Steel provides great strength and durability, especially when galvanized or powder-coated to resist weather. Malleable iron offers toughness and good wear resistance for cast latch mechanisms. Aluminum alloy delivers light weight and excellent corrosion resistance, which is particularly useful in humid or coastal areas. Because all three materials can meet the functional needs of a gate latch when properly finished and installed, any of the above can be used. The key is selecting a latch that matches the gate material, anticipated use, and exposure to elements to ensure reliable operation over time.
