As we introduced the differences between hot-dip galvanizing & zinc galvanizing, then which one should be used for your projects, and why you need to choose that.
Where zinc galvanizing pedestal & stringer suit
In office buildings and commercial buildings, zinc galvanizing pedestal and stringer are used much more than hot-dip galvanizing pedestal and stringer. The stability of zinc galvanizing is worse than hot-dip galvanizing, zinc galvanizing may start to fall off after several weeks while hot-dip galvanizing can remain stable for several years, but price of hot-dip galvanizing can be around five times higher than zinc galvanizing(price in 2016). Taking economic factor into account, zinc galvanizing pedestals and stringers would be the better choice.
Where hot-dip galvanizing pedestal & stringer suit
In a high-grade data center or clean room, hot-dip galvanizing pedestal & stringer would be very necessary. If zinc galvanizing pedestal & stringer are used, when galvanizing start to fall off, they will adhere to electronic devices by static function, as galvanizing is also electric conductor, this may lead a crash of devices, it is unacceptable especially for those devices with high precision. Hot-dip galvanizing pedestal & stringer can avoid or greatly reduce the likelihood of occurrence, so in high-grade data center, serve room, clean room, etc, hot-dip galvanizing pedestal & stringer must be used.
