Slotted hole
Perforated Metal is a specialized type of perforated metal characterized by elongated slots that allow for the efficient passage of air, liquids, and solids while maintaining structural integrity.
Slotted perforated patterns are produced with rectangular or slotted holes. Available with either straight line or staggered alignment, these contemporary products are commonly used for ventilation covers or architectural accents.
Specifications of Slotted Hole Perforated Metal
Material Options
Slotted hole perforated metal can be manufactured from various materials, including:
- Carbon Steel
- Stainless Steel (e.g., Type 304, Type 316)
- Aluminum
- Galvanized Steel
- Specialty Alloys
Dimensions
- Sheet Sizes: Common dimensions include 48" x 96" and 60" x 120", with custom sizes available upon request.
- Thickness: Typically ranges from 0.025 inches to 0.250 inches, depending on the application.
Slot Dimensions
- Slot Widths: Common slot widths range from 1/8 inch to 1 inch or more.
- Slot Lengths: Lengths can vary based on design requirements, typically ranging from 1/2 inch to several inches.
- Patterns: Available in various patterns, including:
- Straight-line patterns
- Side-staggered patterns
- End-staggered patterns
Open Area
- The open area percentage varies based on slot size and pattern, generally ranging from approximately 22% to over 50%. This allows for excellent airflow and drainage capabilities.
Structural Characteristics
- Gauge: The thickness of the material is often specified in gauge, with common gauges ranging from #10 to #22.
