FAQS
The primary difference lies in the manufacturing process. Raised expanded metal undergoes an additional process that elevates the ridges, enhancing its strength, grip, and load-bearing capacity. Standard expanded metal is simply slit and stretched, resulting in a flatter profile. This ‘raising’ effect makes the former preferable for applications requiring increased safety and structural integrity.
Raised expanded metal is commonly manufactured from carbon steel, stainless steel, and aluminum. Carbon steel is cost-effective and suitable for general applications. Stainless steel offers superior corrosion resistance, making it ideal for harsh environments. Aluminum provides a lightweight solution with excellent corrosion resistance. The choice of material depends on the specific application and environmental factors.
The pattern—specifically the strand width, short pitch, and long pitch—significantly impacts the material's performance. A narrower strand width and short pitch increase the density of the mesh, enhancing its load-bearing capacity and providing a finer surface for filtration. Conversely, wider strands and longer pitches offer greater ventilation and visibility.
In industrial settings, raised expanded metal is frequently used for flooring, stair treads, walkways, safety guards, and ventilation screens. Its strength, durability, and non-slip surface make it ideal for protecting personnel and equipment. Its open structure also facilitates airflow and drainage, reducing maintenance requirements.
