Galvanized Iron Duct

Rectangular Galvanized Iron Hotel Kitchen Ducting is an essential component of the kitchen exhaust system, designed to effectively channel smoke, heat, steam, and odors from cooking areas to the outside of the building. This type of ducting is made from galvanized iron, offering durability, corrosion resistance, and strength—ideal for commercial kitchen environments such as those in hotels, restaurants, and other hospitality settings.

A commercial kitchen chimney, also known as a kitchen hood or exhaust hood, is a crucial component in commercial kitchens. Its primary function is to remove heat, smoke, grease, and odors generated during cooking processes. Here are some key features and considerations for a commercial kitchen chimney:

1. Type of Hood:

   • Wall-Mounted Hoods: Attached to the wall and positioned over cooking equipment against the wall.
   • Island Hoods: Suspended from the ceiling and positioned over cooking equipment on islands or peninsula counters.
   • Ductless Hoods: Filters and recirculates air back into the kitchen after removing impurities. However, these are less common in commercial settings due to their limitations.

GI (Galvanized Iron) Spiral Duct is a cylindrical duct used in HVAC (Heating, Ventilation, and Air Conditioning) systems for the efficient distribution of air throughout buildings. These ducts are made from high-quality galvanized iron, which provides excellent durability, corrosion resistance, and strength, making them ideal for both residential and commercial HVAC applications. The spiral design of the duct provides smooth airflow, reduces air resistance, and helps improve energy efficiency in the HVAC system.

GI ducting refers to the installation of ducts made from galvanized iron (GI) sheets for air ventilation and conditioning systems. This is commonly used in commercial and industrial settings to distribute and circulate air. Here are the general steps involved in GI ducting work:
Assessment and Planning:
Conduct a thorough assessment of the space to determine the layout and design requirements for the ducting system.
Consider factors such as the volume of air to be handled, the layout of the space, and any specific requirements for temperature control or air quality.
Duct Sizing and Design:
Determine the appropriate size of the ducts based on the airflow requirements and the layout of the ventilation system.
Design the duct layout, taking into account the optimal path for air distribution and the placement of vents and outlets.
Material Procurement:
Procure the necessary materials, including GI sheets, connectors, supports, insulation, and any other components required for the ducting system.
Cutting and Shaping GI Sheets:
Cut the GI sheets to the required dimensions using appropriate tools.
Shape the sheets according to the design specifications, ensuring a precise fit for assembling the ducts.
Assembling Ducts:
Assemble the GI sheets into duct sections using screws, rivets, or other suitable fasteners.
Ensure that the joints are sealed properly to prevent air leakage.
Insulation (if required):
Apply insulation material to the ducts if thermal insulation is necessary to control temperature or condensation.
This step is particularly important in HVAC systems to prevent energy loss.
Installing Supports:
Install supports for the ductwork to secure it in place. The supports should be sturdy and able to withstand the weight of the ducts.
Connecting Duct Sections:
Connect the individual duct sections to create a continuous pathway for airflow.
Seal the joints with mastic or duct tape to prevent air leakage.
Installing Dampers and Louvers:
Install dampers and louvers at strategic points in the ducting system to control the flow of air and adjust ventilation as needed
