Pre-galvanized Steel (GI) and Pre-Zinc Galvanised Steel (JIS G3302 SGHC/SGCC) are two popular materials used in metal cable management products. In this article, we will discuss the characteristics, pros and cons, and example use cases of these materials in the construction sector and cable management discipline.

Pre-Galvanised Steel (GI)

Pre-galvanized Steel (GI) is a type of steel that has been coated with a layer of zinc to protect it from corrosion. The zinc coating is applied to the steel using a process called pre-galvanization, which involves immersing the steel in a bath of molten zinc. The resulting coating is relatively thin, which makes it suitable for applications where weight is a concern.

Pros

• Lightweight
• Easy to install
• Corrosion-resistant
• Cost-effective

Cons

• Not suitable for outdoor use
• May require additional coating for harsh environments

Example Use Case

Cable trays and cable ladders are common examples of metal cable management products made from pre-alvanised steel (GI). These products are lightweight, easy to install, and cost-effective, making them ideal for use in commercial and industrial buildings. Pre-Galvanised Steel (GI) cable tray

Pre-Zinc Galvanised Steel (JIS G3302 SGHC/SGCC)

Pre-zinc galvanized Steel (JIS G3302 SGHC/SGCC) is a type of steel that has been coated with a layer of zinc using a process called hot-dip galvanization. This process involves immersing the steel in a bath of molten zinc, which results in a thicker and more durable coating than pre-galvanization.

Pros

• High durability
• Excellent corrosion resistance
• Suitable for outdoor use
• Fire-resistant

Cons

• Relatively expensive compared to other materials
• May require specialized tools for installation

Example Use Case

Conduit pipes and fittings are common examples of metal cable management products made from Pre-Zinc Galvanised Steel (JIS G3302 SGHC/SGCC). These products are highly durable, corrosion-resistant, and suitable for outdoor use, making them ideal for use in harsh environments.

Comparison between Pre-Galvanised Steel (GI) and Pre-Zinc Galvanised Steel (JIS G3302 SGHC/SGCC)

• Pre-galvanized Steel (GI) is lightweight and cost-effective, while Pre-Zinc Galvanised Steel (JIS G3302 SGHC/SGCC) is highly durable and corrosion-resistant.
• Pre-galvanized Steel (GI) is suitable for indoor use, while Pre-Zinc Galvanised Steel (JIS G3302 SGHC/SGCC) is suitable for outdoor use.
• Pre-galvanized Steel (GI) may require additional coating for harsh environments, while Pre-Zinc Galvanised Steel (JIS G3302 SGHC/SGCC) does not.

Conclusion

In conclusion, both Pre-Galvanised Steel (GI) and Pre-Zinc Galvanised Steel (JIS G3302 SGHC/SGCC) are popular materials used in metal cable management products. While Pre-Galvanised Steel (GI) is lightweight and cost-effective, Pre-Zinc Galvanised Steel (JIS G3302 SGHC/SGCC) is highly durable and corrosion-resistant. The best material to use depends on the specific application and environment.
