Raised expanded metal is made by shearing and stretching the metal sheet with a set of die on a press, creating diamond shaped openings. The solid intersections of two strands are called bonds that lie on top of each other to form a raised effect. This adds additional strength and rigidity to the expanded metal, also provides directional skid-resistance surface. No material is lost in the manufacturing process, not like the perforated metal production, so it is a green engineered alternative in many projects.
