What are the dimension of metal ceiling tiles?

Most of our real metal ceiling tiles come in either 24" x 24" size or 24" x 48".  The actual sizes slightly differs depending on the application.  If you choose a tile for a suspended ceiling system also known as drop ceiling or a grid system, it will be slightly smaller than 24" x 24" size and 24" x 48", the actual size would be close to 23 7/8" x 23 7/8" and 23 7/8" x 47 7/8".  If you go with a nail-up install option, the tiles are 24 3/8 x 24 3/8 inches or 24 3/8 x 48 3/8 inches. There are couple of odd sizes and we can also create custom tiles with a custom size.
