Ventilation Works (GI and Black Steel Works)

Ventilation Works involve the design, fabrication, installation, and maintenance of ducting and air movement systems that ensure proper air circulation, temperature control, and removal of contaminants from indoor spaces. These systems are essential for maintaining air quality, comfort, and compliance with health and safety standards in residential, commercial, and industrial buildings.

Two commonly used materials in ventilation ductwork are GI (Galvanized Iron) and Black Steel, each selected based on specific application requirements.

1. GI (Galvanized Iron) Ducting Works:
  • Galvanized iron ducts are made from steel sheets coated with zinc to protect against corrosion.
  • Lightweight, durable, and widely used in HVAC systems for distributing air (supply and return).
  • Ideal for general ventilation, air conditioning, and exhaust systems in buildings.
Key Features:
  • Corrosion-resistant
  • Smooth internal surface for efficient airflow
  • Easy to fabricate, install, and maintain
Applications:
  • Offices, malls, hospitals, and residential buildings
  • Kitchen exhausts, fresh air intakes, and air conditioning systems
2. Black Steel Ducting Works:
  • Black steel ducts are made from untreated carbon steel and are stronger and thicker than GI.
  • Commonly used in high-temperature or industrial exhaust applications, especially where fire resistance or durability is critical.
  • Suitable for kitchen hoods, industrial fume extraction, and smoke extraction systems.
Key Features:
  • High strength and durability
  • Suitable for heavy-duty and high-temperature environments
  • Typically painted or coated to prevent rust
Applications:
  • Commercial kitchens and restaurants
  • Industrial facilities and factories
  • Fire-rated duct systems and smoke control systems
Benefits of Ventilation Works Using GI and Black Steel:
  • Improved indoor air quality and ventilation efficiency
  • Durable and long-lasting duct systems
  • Compliance with HVAC and fire safety standards
  • Custom fabrication to suit any building layout
  • Reduces heat, moisture, fumes, and airborne contaminants
