Structural Features and Application Differences Between Perforated Metal and Expanded Metal

Perforated metal is usually produced by punching regular hole patterns with molds. Hole shapes can include round, square and slotted holes, making it suitable for screening, protection, ventilation, decoration and equipment covers.

Expanded metal is made by slitting and stretching metal sheet into a continuous mesh structure. It has good integrity and is often used for walkways, protection, support and engineering structures. Selection should compare load requirements, opening effect, appearance needs and further processing methods.
