A GI perforated sheet is a Galvanized Iron (steel) sheet with precisely punched holes, offering corrosion resistance from its zinc coating, durability, and versatility for air flow, light, and sound control in industrial (filters, guards) and architectural (screens, cladding) uses. These sheets feature various hole shapes (round, square, decorative) and sizes, made strong by the base steel and enhanced by the protective zinc layer for extended life, especially outdoors or in damp conditions. Key Characteristics:

• Material: Galvanized Iron (GI), meaning steel coated with zinc.
• Corrosion Resistance: Zinc coating protects against rust, making it ideal for outdoor/moist environments.
• Perforations: Holes punched in patterns (round, square, oblong, etc.) for specific functions like ventilation, filtration, and aesthetics.
• Strength & Durability: Combines steel's strength with zinc's protective qualities for long-lasting performance.
• Versatility: Customizable hole size, shape, and pattern for diverse applications. 

Common Uses:

• Industrial: Filters, screens (mining, coal), pipe guards, machinery parts.
• Architectural: Sunshades, cladding, fencing, ventilation grills, decorative panels, sound insulation. 

Features:

• Uniform surface and flat shape.
• Light transmission and air permeability.
• Can be powder-coated for added finish
