Paint grip, or bonderized steel, is galvanized steel that has put through a phosphate bath and a chromate dry. The process produces a primer to the steel for painting. The material should be immediately painted after installation. An alternative to paint grip galvanized steel is galvannealed steel.

Furthermore, what is paint lock steel?

Bonderized steel, also referred to as paint grip steel, is galvanized steel that has been put through a phosphate bath and a chromate dry. This process produces the dull grey color characteristic of paint grip galvanized steel which provides an excellent "primer" for painting applications.

Also, does Bonderized metal need to be painted? Bonderized material should be immediately painted after installation, as the exposed phosphate coating is prone to white rust.

Secondly, what does Bonderized mean?

Bonderized steel is actually Galvanized G90 that has been put through a phosphate bath and has a layer of Chromate applied and dried leaving it ready to accept paint. The process produces a dull gray colored finish. Bonderized is commonly referred to as " Paint Grip ".

What is Mill Phosphatized sheet metal?

Galvannealed. Galvannealed is carbon steel coated with zinc/iron alloy on both sides Galvanized steel is cold-rolled carbon steel with a zinc coating on either side.

Does galvanized steel rust?

Galvanized steel takes a long time to rust, but it will eventually rust. This type is carbon steel that has been galvanized, or coated, with a thin layer of zinc. Like aluminum, zinc is highly reactive to oxygen in the presence of moisture, and the coating prevents the iron in the steel from further oxidation.

What is the difference between galvanized and galvannealed?

What is the difference? They both are zinc coated at the mill and are designed for rust and corrosion resistance. Both are passed through a hot dip coating process; however Galvannealed steel goes through an additional annealing process, which induces diffusion alloying between the molten zinc coating and the steel.

What is GA material?

Galvannealed and galvanized steel are zinc coated at the steel mills and are designed for rust and corrosion resistance. Both steels are passed through a hot dip coating process for rust prevention.

What is galvannealed sheet?

Galvannealed (or galvanneal) Steel is a carbon steel sheet coated with zinc on both sides by the continuous hot-dip process. The galvannealed surface has a non-spangled matte finish, a finish very different than the highly metallic appearance of the galvanized coating.

What is g60 Steel?


Galvanization, or galvanization, (galvanizing as it is most commonly called in that industry), is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc.

What does ASTM a653 mean?

ASTM A653 / A653M Standard Specification for Steel Sheet, Zinc-Coated (Galvanized) or Zinc-Iron Alloy-Coated (Galvannealed) by the Hot-Dip Process. This specification covers steel sheet, zinc-coated (galvanized) or zinc-iron alloy-coated (galvannealed) by the hot-dip process in coils and cut lengths.

Can you paint Galvanneal?

At times, the galvannealed coating may appear similar to uncoated cold rolled steel. One of the primary attributes of the galvannealed coating is that the surface accepts paint very readily. It can be painted without the application of a pretreatment, although a pretreatment will enhance the performance after painting.

How is galvanized steel made?

Galvanized steel is a carbon steel that has been coated with zinc. The most common method of zinc coating is the hot-dip process. When the material is removed from the zinc bath and cooled a reaction to the oxygen in the air occurs. The reaction causes the zinc to become part of the steel (an iron-zinc alloy bond).

Does Galvalume come in colors?

Galvalume®*
Galvalume® has a highly reflective, silver spangled color which weathers in unique patterns over the life of the roof for a rustic, natural appearance. * Galvalume® is the successor to the Galvanized coating that has been in use since the 1800's.

What is Phosphatized steel?


Parkerizing, bonderizing, phosphating, or phosphatizing is a method of protecting a steel surface from corrosion and increasing its resistance to wear through the application of a chemical phosphate conversion coating.

What is Spangle in galvanized steel?

Spangle Galvanized Steel
The spangle is a unique and interesting formation on the galvanized surface. It is created by use of trace metals in the molten zinc, and by controlling the cooling process of the hot-dip zinc coating on the steel.

How do you paint galvanized duct?

Prime the metal with an acrylic latex metal primer. Brush the primer with a synthetic bristle paintbrush or, if you want to avoid brush marks, spray it using aerosol cans or air spray equipment. If the ducts will get hot, use a primer with a high heat resistance.

How do you paint metal ductwork?

Paint. Oil-based paint that is rated for use on metal works best on furnace ducts. Avoid latex or regular paint because it will not adhere properly, even on top of a coat of primer. Use a paint roller in visible spots for a smooth finish and a paintbrush for other areas.

How do you prepare ductwork for painting?

Re: Painting Metal Ductwork
first wipe down with mineral spirits or a degreaser. then prime then paint. The white vinegar will etch the zinc so the primer can bond but it won't clean off the oil. the degreaser will remove the oil but won't etch the zinc.

How do you paint exposed ductwork?


If your ducts are located in an out-of-the-way area, it's probably okay to use a paintbrush. However, if your ducts are in a prominent area, spray paint will look better on your duct system. It's also important to prime the metal with an acrylic latex metal primer when using latex paint.
