What is Bonderized Steel? (Paint Grip Steel)

Bonderized steel is galvanized steel that is processed through a phosphate bath. This provides a corrosion inhibiting, crystalline zinc phosphate, micro-porous surface that promotes adhesion of top coatings. This produces the dull gray color characteristic of Bonderized that provides as an excellent “primer” for painting applications. Phosphate acts as an insulator between the drying action of the galvanized coating and the paint, promoting longer paint adhesion. That is why it has been called “Paintgrip” by the trade. Bonderized material should be immediately painted after installation, as the exposed phosphate coating is prone to white rust.

Operating a Seamless Gutter Machine

Anyone who is going to operate a gutter machine must first read and understand the manual provided by the machine manufacturer.  The first reason is the safety of the operator—the manual will guide you on safe practices that will help you avoid personal injury.  The second reason is to properly operate the machine so it will produce hi-quality gutter and avoid damage to the machine. A seamless gutter machine typically produces about 30 feet of gutter per minute.  It usually only needs to be operated a few minutes per day to produce the gutter required for that day’s work. In most cases the gutter machine will have been transported to the worksite with a coil of material on the machine and then… Continue reading »
