Ritilälevyjä

Ritilälevyjä, often translated as perforated sheets or expanded metal mesh, are sheet metal products that have been expanded or punched with a pattern of holes. They are manufactured from a single sheet of metal, typically steel, aluminum, or stainless steel, which is simultaneously slit and stretched to create a diamond-shaped, hexagonal, or other patterned opening. This process results in a strong, lightweight material with excellent strength-to-weight ratio.

The open structure of ritilälevyjä allows for ventilation, drainage, and light penetration. They are widely used in various industries due to their versatility and durability. Common applications include architectural elements like facade cladding, balustrades, and ceiling panels, providing both aesthetic appeal and functional benefits. In industrial settings, they serve as walkways, gratings, stair treads, machine guards, and screening. Their robust nature makes them suitable for heavy-duty applications where resistance to impact and wear is required. The pattern and size of the openings can be customized to meet specific project requirements, offering a high degree of design flexibility. Ritilälevyjä are also known for their cost-effectiveness compared to other mesh or grating materials.
