Red brick is a type of building material that has been used in construction for thousands of years. It is made from clay that is fired at high temperatures to create a hard, durable, and weather-resistant material. Red brick gets its distinctive color from the iron oxide present in the clay.

Common sizes for red bricks include 8 x 4 x 2 inches and 9 x 4.5 x 2.5 inches. Red bricks can be manufactured to meet different standards and specifications, such as ASTM C216-19 Standard Specification for Facing Brick (Solid Masonry Units Made from Clay or Shale).
