Plastic wall plates are suitable for most household applications. They are designed to resist sparks, fading, discoloration, water, etc. In addition, wall plates made of plastic are usually cheaper than other materials and can last quite a long time.

Polycarbonate Thermoplastic (PCT)

Unlike plastic plates, thermoplastic wall plates are made with solid heat resistance. They also don’t fade that readily, even after being exposed to light for longer. As a result, thermoplastics are replacing plastics as they are more reliable and work great for residential and commercial spaces.


You won’t see metal wall plates much in residential or commercial spaces because plates like that are used in basements, workshops, warehouses, etc. Metal wall plates are made for heavy usage with rounded corners to help prevent any form of injury. They are easy to clean as well. Metal wall plates come in a variety of metals forms such as stainless steel, brushed brass, aluminum, polished brass, etc.

Antimicrobial Treated Wall plates

Another kind of wall plate is the antimicrobial wall plate. As the name suggests, the wall plates have antimicrobial properties that reduce the growth of bacteria and other germs. These wall plates are made of polyurethane coating embedded with a silver ion additive. This polyurethane coating hinders the growth of fungi, mildew, and mold. Wall plates like these are primarily used in hospitals, schools, healthcare, food service, etc.
