Is All Galvanizing the Same?
No! There are two different types of galvanized pipe: in-line (triple coat/Gatorshield or pre-galvanized) and post production hotdipped galvanized. While both use zinc coating, the application is the most critical part. 

Britespan applies hot dipped galvanizing to all of their trusses post production (after all fabrication is complete), which uses an entirely different process to ensure lifelong corrosion protection and a much longer service life. We start with untreated black structural steel.  We bend and weld the raw steel into our trusses.  Holes are drilled into the pipe to ensure the galvanizing reaches every surface.  After that, the trusses are submerged in a bath of molten zinc where they receive a coating on every surface inside and out that is three times thicker than the coating  on the outside of  in-line galvanized pipe.  This process means that your building will offer a service life that is approximately three times longer than the in-line galvanized alternative.

In-line galvanized pipe is rolled through a waterfall of zinc and the pipe is coated on the outside, painted on the inside, and is then sent out to be manufactured. The pipe is bent, welded into trusses, and shipped out.  Unfortunately, the welding of the trusses burns off the paint on the inside of the pipe, leaving it unprotected and susceptible to rust before it ever gets erected.
