Standard GI Channels

Standard GI channels are the most commonly used profiles in construction and industrial applications. Key features include:

• Dimensions: Common sizes include 75x40mm, 100x50mm, and 125x65mm with thicknesses ranging from 1.6mm to 3.2mm
• Applications: Used in general construction, roofing supports, false ceiling frameworks, and industrial structures
• Advantages: Excellent load-bearing capacity, corrosion resistance, and versatility

These standard channels form the backbone of many structural applications across Kolkata's construction industry.

Lightweight GI Channels

Lightweight GI channels offer reduced weight without compromising structural integrity. Features include:

• Dimensions: Typically 50x25mm, 65x35mm with thicknesses of 1.2mm to 1.6mm
• Applications: Ideal for false ceilings, partition walls, light-duty shelving, and non-load-bearing structures
• Advantages: Easier handling, reduced structural load, and cost-effectiveness

These lightweight options are particularly popular in commercial interiors and residential construction projects across Kolkata.

Custom GI Channel Solutions

Beyond standard offerings, Kolkata's GI channel manufacturers provide customized solutions including:

• Perforated GI Channels: Featuring pre-drilled holes for easier assembly in applications like cable trays, shelving, and modular structures
• Cut-to-Length GI Channels: Precision-cut channels according to client specifications, reducing on-site cutting and wastage
• Pre-Fabricated Assemblies: Ready-to-install channel assemblies for specific applications, saving time and labor costs
• Heavy-Duty GI Channels: Reinforced channels for high-load applications in industrial structures and heavy machinery supports

These customized solutions demonstrate the versatility and adaptability of Kolkata's GI channel manufacturing capabilities.

Raw Material Preparation

The manufacturing process begins with the selection of high-quality mild steel, typically in the form of hot-rolled coils or sheets. These materials undergo thorough inspection for chemical composition, surface quality, and dimensional accuracy before proceeding to the next stage.

Channel Forming

The steel is then processed through one of two primary methods:

• Hot Rolling: For larger channels, the steel is heated to approximately 1200°C and passed through a series of rollers that gradually form the C-shaped profile. This process ensures uniform material properties and excellent structural integrity.
• Cold Forming: For smaller channels, the steel is bent at room temperature using precision press brakes or roll-forming machines. This method provides excellent dimensional accuracy and surface finish.

After forming, the channels are cut to standard lengths, typically 6 meters, though custom lengths are available upon request.

Hot-Dip Galvanizing Process

The distinctive feature of GI channels is the galvanization process, which involves:

1. Surface Preparation: The channels undergo thorough cleaning through degreasing, acid pickling, and fluxing to remove all contaminants and prepare the surface for zinc adhesion.
2. Hot-Dip Galvanizing: The prepared channels are immersed in a bath of molten zinc at approximately 450°C. During this process, the zinc metallurgically bonds with the steel, forming a series of zinc-iron alloy layers topped with a layer of pure zinc.
3. Cooling and Passivation: After galvanizing, the channels are cooled and often treated with a passivation solution to prevent the formation of white rust during storage.

This galvanizing process provides a protective zinc coating typically ranging from 45 to 85 microns in thickness, depending on the steel thickness and application requirements.
