Salt spray. Chemicals. Temperature extremes. Your steel faces these every single day.

When steel is exposed to aggressive environments like ammonia-rich agricultural air, salt spray, or chemical-heavy industrial settings, standard protection simply won’t cut it. That’s where MAGNA-SHIELD PRO™(MSP) stands out.

Developed for Millform Australia®, MSP is a future-ready, cold-rolled steel solution that offers:

• Superior corrosion resistance
• Enhanced durability
• And long-term performance in the most demanding applications.

Whether you’re specifying materials for coastal builds, industrial zones, or agricultural infrastructure, MSP provides a smarter, longer-lasting defence.

What is MAGNA-SHIELD PRO™ (MSP)?

MAGNA-SHIELD PRO™ (MSP) is a next-generation, advanced coated steel engineered with a high-performance ZM350 coating. This unique blend of zinc, 5% aluminium, and 3% magnesium delivers exceptional resistance to corrosion, abrasion and chemical exposure.

MSP is cold-rolled steel designed for a wide range of applications. It meets the AS 1397:2021 standard and is ideal for components such as C and Z section purlins, downturn lip purlins, junction studs, trim angles and bridging.

Unlike traditional galvanised products, MSP eliminates the need for post-galvanising and delivers a premium finish with compatibility for powder coating and concrete applications.

With a refined satin matt appearance and bright, uniform finish that weathers to a sleek metallic sheen, MSP is designed to perform and impress.

In certain applications, MSP offers a design life up to or exceeding 100 years.

How Does MAGNA-SHIELD PRO™ (MSP) Protect Steel in Harsh Conditions?

MSP protects steel using a multi-layered defence mechanism that goes far beyond conventional coatings.

Corrosion Resistance The ZM350 coating forms a durable barrier against moisture, salt, chemicals and airborne pollutants. This is especially critical in marine, coastal, and chemical-heavy environments.

Abrasion and Scratch Resistance MSP offers enhanced surface hardness, significantly improving its ability to withstand mechanical wear and abrasion in high-traffic or equipment-heavy areas.

Salt Spray Durability Over 4000 hours of salt spray testing confirm MSP’s long-term performance in coastal and marine environments, substantially reducing maintenance cycles and costs.

Chemical Resistance MSP maintains structural performance when exposed to fertilisers, ammonia, high-humidity air, and industrial compounds, making it ideal for petroleum refineries, chemical processing plants and agricultural facilities.

Temperature Resilience Its advanced coating technology ensures protective properties remain stable even under fluctuating or elevated temperatures.

Self-Healing Action Magnesium in the coating contributes to the formation of protective compounds that reduce corrosion initiation at cut edges and scratches.

Applications Across Australia’s Toughest Industries

MAGNA-SHIELD PRO™ (MSP) is made for Australian conditions and has proven its value in some of the country’s most demanding environments:

Industrial and Commercial Projects From petroleum refineries to environmental labs, MSP delivers chemical resistance and long-term structural protection, minimising the risk of degradation, corrosion, and failure over time.

Agricultural and Horticultural Facilities MSP withstands high-ammonia, high-moisture environments like feedlots, fertiliser storage and produce sheds. 

Marine and Aquatic Environments MSP excels in saltwater-exposed settings such as boat sheds and marinas, where standard coatings quickly deteriorate. Its salt spray durability ensures reduced maintenance in high-humidity environments.

Coastal and High-Salinity Areas Water treatment plants and coastal structures face year-round salt attack. MSP offers consistent, long-term protection against these aggressive conditions.

Chemical Processing Environments Storage facilities and chemical plants face constant exposure to harsh substances. MSP delivers reliable, long-term protection against corrosion and structural breakdown, reducing the risk of leaks and failures over time.
