The profile is bent with both hands, and the twisting strength is good, and it can be restored after loosening your hands. If the strength of the aluminium profile is not enough, it is easy to be deformed, which may result in unqualified wind pressure resistance level, the finished switch is not smooth, and the deformation amount is too large.

Unlike spray-on rust prevention coatings that only cover exposed surfaces, hot dip galvanization coats the outside, inside and underside of the dipped pieces.  The biggest problem with lower end spray coatings is that the pieces will often rot from the inside out and by the time you see it, the piece is already ruined.  Look for specifics on how the pieces are treated to prevent rust.  Our Stronghold Iron line utilizes a hot dip galvanization, a 4-stage chemical wash and then use a TGIC poly-based powder coating with UV fade inhibitors to protect our pieces.
