AMICO Expanded Metal Grating is a heavy-duty form of expanded metal designed for high-strength, load-bearing applications. Made from thicker sheet or plate, it features larger diamond openings and deeper strands for maximum durability and traction.
Its one-piece construction eliminates the need for welding, reducing weak points while maintaining structural integrity. Expanded metal grating is commonly used for industrial flooring, catwalks, platforms, and ramps, offering excellent slip resistance, drainage, and long service life in demanding environments.
