MP-PZ4: The modern industrial standard with maximum flexibility

MP-PZ4 represents the best of both worlds: the revolutionary zinc-magnesium coating (Z4) and a perforated design. While the classic ladder has smooth rungs, MP-PZ4 is equipped with a continuous hole pattern that allows you to attach cables, boxes, and components with zip ties exactly where you want.

Self-healing and extremely durable

Just like the other products in the Z4 series, MP-PZ4 has a unique ability to heal itself. If you cut or drill into the ladder, the coating flows over the exposed surface and restores the protection. This is a huge advantage with perforated rungs, as every hole and cut surface remains protected against rust throughout the product's lifespan.

Flexibility that saves time

The integrated hole pattern in the rungs is a dream for the installer. Instead of being limited to the side profiles, you can secure cables evenly across the entire width of the ladder. This makes MP-PZ4 ideal for:

• Control systems and instrumentation with many small cables.

• Installations where cables need to be separated at exact distances.

• Environments where extra securing is required due to vibrations or vertical pulls.

Environment class C4 – built for industry

The Z4 coating provides a level of protection equivalent to hot-dip galvanising but with a significantly smoother and neater finish. MP-PZ4 is approved for corrosion class C4, making it perfect for:

• Humid industrial environments and production halls.

• Chemical industries and wastewater treatment plants.

• Modern parking garages and infrastructure projects.

Economy and sustainability in one

Thanks to the efficient manufacturing process, MP-PZ4 is both lighter and more affordable than traditional hot-dip galvanised perforated ladders (MP-PZ), without compromising on load-bearing capacity. The lower weight makes transport cheaper and assembly significantly gentler on the body.

Part of a complete ecosystem

MP-PZ4 is fully compatible with MP bolagen's wide range of joints, angles, and brackets. By using the entire Z4 system, you achieve a uniform installation where all parts have the same high corrosion protection and are optimised for rapid potential equalisation.
