When it comes to construction, fencing, industrial applications, and infrastructure projects, weldmesh is a popular choice due to its strength, versatility, and cost-effectiveness. Among the different types of weldmesh available, MS (Mild Steel) Weldmesh and GI (Galvanized Iron) Weldmesh are the most commonly used. While they may look similar, both have different properties, advantages, and use cases.
In this blog, we’ll dive deep into the difference between MS and GI Weldmesh, helping you make the right choice for your next project.
What is Weldmesh?
Weldmesh is a prefabricated grid made from a series of wire strands that are welded together at their intersections. It is widely used for fencing, cages, partitions, construction reinforcements, and more.
The two most common types based on material and treatment are:
- MS Weldmesh (Made from Mild Steel)
- GI Weldmesh (Made from Galvanized Iron wire)
What is MS Weldmesh?
MS Weldmesh is manufactured using mild steel wires that are welded at intersections to form a mesh. Mild steel is a low-carbon steel known for its strength and ductility.
Key Features of MS Weldmesh:
- Made of low-carbon mild steel
- High tensile strength
- Suitable for welding and bending
- Cost-effective
- Can be prone to rust if not coated
Common Uses of MS Weldmesh:
- Construction reinforcements
- Temporary barriers
- Cages for machinery or animals
- Industrial enclosures
What is GI Weldmesh?
GI Weldmesh is made from galvanized iron wires that have been coated with a layer of zinc. This zinc coating protects the mesh from rust and corrosion, making it ideal for outdoor or moisture-prone applications.
Key Features of GI Weldmesh:
- Zinc-coated to prevent rust
- Long-lasting and corrosion-resistant
- More durable than MS Weldmesh in outdoor settings
- Slightly more expensive due to galvanization
Common Uses of GI Weldmesh:
- Fencing for gardens, parks, and industrial areas
- Animal enclosures
- Marine or coastal applications
- Protective barriers
Main Differences Between MS and GI Weldmesh
| Feature | MS Weldmesh | GI Weldmesh |
| Material | Mild Steel | Galvanized Iron |
| Rust Resistance | Low (unless painted/coated) | High (zinc-coated) |
| Durability | Good for dry indoor conditions | Excellent for outdoor/wet environments |
| Cost | Lower | Slightly higher |
| Weight | Slightly heavier | Slightly lighter (due to thinner wires used in galvanization) |
| Appearance | Matte grey/black | Shiny silver |
| Maintenance | Requires regular maintenance | Low maintenance |
| Best Use | Construction, indoor cages | Fencing, outdoor applications |
Which One Should You Choose?
Choosing between MS Weldmesh and GI Weldmesh depends on the environment and application:
- If your project is indoors or temporary, and cost is a major concern, MS Weldmesh is a suitable choice.
- If you need a permanent solution for outdoor or humid conditions, go with GI Weldmesh for its durability and rust-resistance.
Advantages of Using MS Weldmesh
- Budget-friendly for bulk use
- Ideal for DIY or short-term installations
- Can be painted or powder-coated for protection
- Good for indoor cages, partitions, and construction
Advantages of Using GI Weldmesh
- Withstands harsh weather and moisture
- Long-lasting and minimal maintenance
- Better return on investment over time
- Ideal for boundary fencing and security
Environmental Impact and Sustainability
- MS Weldmesh can be recycled easily but may need additional surface treatments to avoid corrosion.
- GI Weldmesh is more sustainable in the long term due to its extended lifespan and resistance to degradation.
Both types can be eco-friendly if disposed of or recycled properly.
10 Frequently Asked Questions (FAQs)
1. Is GI Weldmesh stronger than MS Weldmesh?
In terms of corrosion resistance, yes. But in terms of raw strength, both can be equally strong depending on wire thickness and grid size.
2. Can MS Weldmesh be used outdoors?
Yes, but it must be painted or coated to prevent rust. Otherwise, it may deteriorate quickly in wet or humid conditions.
3. What does “galvanized” mean in GI Weldmesh?
Galvanization is the process of applying a protective zinc coating to iron or steel to prevent rusting.
4. Is GI Weldmesh more expensive than MS Weldmesh?
Yes, due to the added galvanization process, but it lasts longer, especially outdoors.
5. Can I weld GI Weldmesh?
Yes, but special care must be taken to avoid inhaling fumes from the zinc coating. Welding also damages the coating at the weld point.
6. Which is better for fencing: MS or GI Weldmesh?
GI Weldmesh is better for fencing, especially outdoors, due to its rust-proof nature.
7. Can MS Weldmesh be galvanized later?
Yes, MS Weldmesh can be galvanized after fabrication for added protection.
8. Is GI Weldmesh suitable for coastal areas?
Yes, it performs well in coastal or high-humidity environments due to its anti-corrosive properties.
9. Are there different types of galvanization?
Yes, common types include hot-dip galvanization and electro-galvanization, each offering different levels of protection.
10. Can I paint over MS Weldmesh or GI Weldmesh?
Yes, both can be painted, but GI surfaces need a primer suitable for zinc-coated metals.
Conclusion
Both MS Weldmesh and GI Weldmesh serve valuable purposes in industrial and domestic applications. The key to choosing the right one lies in understanding the environment, durability needs, and budget constraints.
- For indoor use or budget-friendly projects, MS Weldmesh is a practical choice.
- For outdoor, long-term, or weather-exposed use, GI Weldmesh offers better durability and value.
No matter your choice, using the right weldmesh ensures safety, strength, and longevity in your projects.
