Galvanizing

Hot Dip Galvanized Steel Frame Supported Structures

 

Post-fabrication hot dip galvanized provides the best corrosion protection available. There is no substitute.

 

For anyone considering steel famed buildings and structures, careful thought must be given to the construction quality being proposed by the supplier. This will ensure that you get the best building for your money. For example, there are three different steel protective processes that can be employed. The quality and longevity of the finished structure is dependent upon the method chosen.

 

 

1. Painted Black Steel (NOT ADVISED)

 

In this process the steel framework is welded together and then painted before being erected on site. Unfortunately, the paint is susceptible to chipping, particularly during handling and transportation, and such damage results in rust and a reduced lifespan.

 

2. Pre-Galvanized Steel (NOT ADVISED)

 

Here zinc galvanized tubes are first bent or welded together then the “black” areas are treated with a special paint to prevent corrosion. This process is used by several fabric building manufacturers and the main benefit is a reduced cost. However, the weld points usually start to rust, even though they have been painted, and the result is, again, a limited lifespan and unsightly appearance.

 

3. Hot-Dip Galvanized

 

In this process, the complete framework is built of welded black steel and then hot-dip galvanized to provide a consistent zinc coating over the entire structure. All Rubb Buildings are Hot-Dip Galvanized post-production for the highest level of quality and longevity.
