REINFORCMENT: GALVANISED VS NON-GALVANISED

Reinforcement mesh is a fundamental component in the construction industry, providing structural support in concrete structures. When it comes to choosing the right type of mesh, one crucial consideration is whether to opt for galvanised or non-galvanised reinforcement mesh.

In the following article, we’ll delve into the characteristics, benefits, and applications of both types, helping you make an informed decision for your construction project.

Non-galvanised reinforcement mesh, also known as black steel mesh, is made from plain steel wire without any protective coating. It is primarily used for applications where corrosion resistance is not a primary concern.

Raw Steel Appearance: Non-galvanised mesh has a characteristic dark, raw steel finish. Cost-Effective: Non-galvanised mesh tends to be more budget-friendly compared to galvanised options. Weldability: It can be easily welded to form custom shapes and sizes, providing flexibility in design.

Foundations: Non-galvanised mesh is commonly used in concrete foundations, footings, and slabs. Projects where exposure to moisture and harsh weather conditions is minimal

Susceptible to Corrosion: Without a protective coating, non-galvanised mesh is vulnerable to rust and corrosion over time, especially in environments with high moisture levels. So if your project is on the coast this is important to take into consideration

Galvanised mesh (galv mesh) is made from steel wire that has undergone a galvanisation process. Galvanisation involves coating the steel wire with a protective layer of zinc through a hot-dip or electroplating process. This process creates a corrosion-resistant barrier that shields the underlying steel from environmental elements such as moisture, humidity, and chemicals. As a result, galvanised mesh exhibits a high level of durability and longevity, making it suitable for outdoor and high-moisture environments.

Corrosion Resistance: The galvanised coating provides a strong defense against rust and corrosion. This makes galvanised mesh an excellent choice for applications where exposure to moisture is likely.

Outdoor Projects: Galv mesh is well-suited for outdoor applications where exposure to moisture, chemicals, or corrosive elements is likely. Coastal Areas: It is highly recommended for construction projects in coastal regions, where saltwater and high humidity levels pose a corrosion risk.

Cost: Galvanised mesh may have a higher upfront cost compared to non-galvanized options, but the long-term benefits in terms of durability can outweigh this initial expense

Choosing between non-galv, black mesh,and galv reinforcement mesh depends on the specific requirements of your construction project. Non-galvanised mesh is suitable for applications with low moisture exposure, offering cost-effective solutions.

On the other hand, galvanised mesh is the preferred choice for coastal areas, and environments prone to corrosion, thanks to its superior rust resistance and extended lifespan.

Ultimately, understanding the characteristics and benefits of each type of mesh will help you to make an informed decision, ensuring the longevity and structural integrity of your construction project.
