9. Perforated Sheet Technology – Expert FAQ
1. What are the main differences between MS and SS perforated sheets?
MS (Mild Steel) offers cost efficiency and moderate strength but requires surface treatment for corrosion resistance; SS (Stainless Steel) provides exceptional corrosion resistance, longevity, and meets strict hygiene standards (FDA, ISO 22000).
2. How does open area affect perforated sheet performance?
Open area (% of the total sheet that is open) directly influences airflow, filtration capacity, and load-bearing. Higher open area improves filtration and ventilation but can reduce structural strength.
3. What standards govern perforated sheet manufacturing?
Leading standards include ISO 9001:2015 (quality management), ASTM A240/A36 (material), ANSI B32.3 (tolerances), and FDA (food safety). Compliance ensures repeatability and reliability.
4. What is the typical installation method for square wire perforated sheets?
Installation options: bolted frameworks, spot welding, or modular clips. Custom flanges & pre-punched holes can be provided for easier assembly. Always follow local load and building safety codes.
5. How to specify the right perforation pattern?
Consider hole shape, size, pitch, sheet thickness, and open area based on your flow/filtration needs, aesthetics, and strength. Square patterns offer uniform flow and efficient filtration for many industrial and architectural uses.
6. What kind of surface finishes are available?
For MS: hot-dip galvanizing or powder coating. For SS: brushed, mirror-polish, pickling & passivation. These prevent corrosion and enhance hygiene, appearance, or paint adhesion.
7. How does a perforated sheet compare with wire mesh?
Perforated sheets offer higher strength, precise apertures, and predictable airflow, while wire mesh offers flexibility and is suitable for lighter or more flexible applications. Certain applications, such as high-pressure filtration or facades, demand perforated sheets for safety and durability.
