Doing metal containment installations?
Hot Dipped Galvanised not proving to be good enough over the long term, and stainless steel is still too expensive.
There’s a better way – and it’s cheaper, better finished and more environmentally friendly.
Traditional hot-dip galvanised steel is increasingly failing in today’s tougher environments. Coastal sites, agricultural buildings, and industrial facilities cause galvanised coatings to break down faster — especially on cut edges and drilled points. The result is corrosion, call-backs, and premature product replacement that costs contractors time, money, and reputation.
That’s why we’re introducing Magnelis®, a next-generation zinc–aluminium–magnesium coating now available across our electrical containment and support ranges. Magnelis® delivers dramatically higher corrosion resistance and features a unique self-healing action on edges and scratches — solving the problems that standard galvanising can’t keep up with.

Magnelis®: The New Standard for Long-Lasting, Low-Impact Electrical Installations
Electrical installations today face harsher environments than ever — from coastal exposure and ammonia-rich agricultural buildings to industrial sites where corrosion is constant. Traditional galvanised steel struggles to keep pace, while stainless steel often pushes budgets too far.
Magnelis® offers a modern alternative that solves both problems.
What Is Magnelis®?
Magnelis® is a technologically advanced zinc–aluminium–magnesium coating applied to steel using a continuous hot-dip process. The addition of magnesium creates a stable, highly protective layer that delivers up to 3–10× more corrosion resistance than standard galvanising.
Unlike batch hot-dip galvanising, this process produces a controlled, uniform coating and — crucially — offers a self-healing effect on cut edges, scratches, and drilled areas.
Why It Outperforms Traditional Galvanised Steel
Electrical contractors benefit immediately from the improvements:
- Up to 10× greater corrosion protection
- Self-healing on edges and cuts, preventing early rust
- Performs exceptionally in coastal, industrial, and agricultural environments
- Thinner coatings outperform thicker galvanised layers
- A more economical alternative to stainless steel with similar long-life performance
The result: longer-lasting installations and fewer call-backs.
Environmental Advantages Over Hot-Dip Galvanising
Magnelis® doesn’t just perform better — it comes with meaningful sustainability benefits:
✔ Less Zinc Used
The coating requires substantially less zinc than traditional batch galvanising, reducing raw material extraction and processing.
✔ Lower Production Energy
The optimised coating thickness allows a more efficient, lower-energy manufacturing process.
✔ Minimal Zinc Run-Off
Magnelis® releases fewer zinc ions into soil and water, which is especially important for agricultural and coastal installations.
✔ Longer Service Life = Less Waste
A longer lifespan means fewer replacements, reduced metal use, and lower environmental impact over the entire lifecycle.
Magnelis® is increasingly favoured on projects with BREEAM*, LEED**, or sustainability requirements.
Where Contractors Are Using Magnelis®
Magnelis® is fast becoming the first choice for:
- Cable containment systems
- Unistrut and bracketry
- Solar mounting structures
- HVAC and mechanical supports
- Outdoor lighting poles and infrastructure
- Industrial and agricultural installations
- Any environment with high moisture, ammonia, or salt exposure
If the environment is harsh, Magnelis® is the upgrade that protects your work.
Why Installers Are Making the Switch
Contractors choose Magnelis® because it delivers on every critical measure:
- Longer-lasting protection
- Faster installation = labour cost savings
- No need to purchase additional galvanising spray
- Reduced maintenance and fewer failures
- Lower total project cost
- Greener, more sustainable materials
- Better client satisfaction with fewer issues over time
It is simply a smarter, more modern material choice.

* BREEAM = Building Research Establishment Environmental Assessment Method
- It’s a leading sustainability assessment standard used mainly in the UK and Europe.
- It evaluates buildings on energy use, materials, pollution, water, waste, ecology, and overall environmental performance.
- A high BREEAM rating helps buildings meet planning requirements and sustainability goals.
** LEED = Leadership in Energy and Environmental Design
- It’s an internationally recognised green building certification system developed by the U.S. Green Building Council.
- LEED scores buildings on energy efficiency, materials, water usage, air quality, carbon impact, and sustainable design.
- It is widely used in North America and increasingly across global commercial projects.
