Final answer:
Every floor drain should have a grate that allows water to pass through while preventing large debris from entering. The grate should be made of materials that are durable and resistant to corrosion.
Step-by-step explanation:
The grate of every floor drain should be designed to ensure effective drainage while also preventing large debris from entering and clogging the drain system. The grate is the cover that sits on top of the drain and allows water to flow through while trapping any solid objects. It is typically made of materials such as stainless steel or cast iron, which are durable and resistant to corrosion. The design of the grate may vary based on the specific application, but in general, it should have openings small enough to prevent objects like coins or jewelry from falling through while still allowing water to pass.
