Z4 has more advantages and replaces traditional hot dip galvanizing.

We have developed both cable ladders and wire mesh trays. The material is surface treated before welding and bending, in this way the sharp edges are avoided that can occur in traditional hot dip galvanizing.
The transporation of the ladders to a factory for surface treatment after production is not needed either. The corrosion resistance compared to ordinary hot dip galvanizing is better and compares with a surface thickness of more than 85 μm. Normally recommends a level of 60 μm for outdoor use.

When installing in server sites for example it´s preferable to use wire mesh trays in oou Z4 material and cable ladders in sendzimir (pregalvanized) material and accessories. This is to avoid Zink Whiskers that is described in the linked document. Zink Whiskers.

A better environmental solution - less transports, higher corrosion resistance and a lower price!
