Expanded & Perforated Sheets

Select material based on application: stainless steel for corrosion resistance and food or medical use, aluminum for light weight and nonmagnetic needs, and carbon steel for strength and lower cost; consider finish (mill, anodized, or painted) for environment and appearance

Choose thicker gauges for structural or load-bearing uses and thinner gauges for screening or ventilation; larger openings and lower open-area percentages increase airflow but reduce strength, while smaller openings increase strength and provide finer filtration

Open area determines airflow and light transmission; strand width (web) affects load capacity and shear strength; hole or mesh pitch controls filtration size and particle passage—balance these to meet strength, airflow, and screening requirements

Common services include laser or waterjet cutting, CNC bending, and slitting; tolerances depend on material and process but are typically tighter for laser cutting and CNC work—specify required dimensions and edge finish when ordering

Store sheets flat and supported to avoid warping, separate dissimilar metals to prevent galvanic corrosion, keep in a dry, ventilated area, and clean with appropriate mild detergents; remove sharp burrs and apply protective coatings if used outdoors

Wear cut-resistant gloves, eye protection, and long sleeves to guard against sharp edges and burrs; use proper lifting methods or equipment for large panels and secure sheets during cutting or welding to prevent movement and injury

Prices vary by material, thickness, pattern complexity, and finishes; budget options commonly fall under $50 for small hobby pieces, while commercial or custom panels can range higher, with average product prices typically in the mid-range for industrial sizes
