Iron type is one of the strongest types of floor drainage grates. The material is strong enough to carry heavy loads on highway drainage covers, so they can provide a lot of stability. Because they can handle a lot of weight and stress, they are popular in industrial buildings. Iron type grates are usually made of ductile iron.

Steel-type metal floor drainage grates are slightly lighter in weight than iron-type grates are. They are sturdy and do not break easily, so they can help prevent break-ins from the ground level. Manufacturers usually produce them by pressing the steel into patterns, and they can come in double- or single-locking forms. They can carry different weights depending on the size of the grate.

HDPE in-line drainage type grates are not always made of metal. Often, they are made of HDPE (high-density polyethylene). However, despite the name, this type of grate can also be made of ductile iron or steel. HDPE in-line drainage type grates are lightweight and easy to install. They are also fairly durable and resistant to damage from chemicals.

Polymer concrete is another common material for drainage grates. The material is popular for both home and industrial use.
