Fairhill Industries’ PRIME ZINC is a high performance coating system. Liquid compounds with high content of zinc in the dry film bond to protected iron, steel or aluminum through galvanizing action to provide maximum protection against rust and rust creepage.
Kobe Steel manufactures and markets the following galvanized steel sheet products for a wide variety of industrial applications. G90, G60 and A60 are approved by UL (Underwriters Laboratories, Inc.) of the U.S. Note 1For electrogalvanized steel sheets over

o Galvanneal steel is, as its name implies, annealed. This annealing softens the steel, making it more prone to dings and dents. o Mill phosphatized steel has a zinc phosphate coating. Zinc phosphate is considered dangerous to aquatic life and special handling is required at the mill to prevent its release into the environment.
90 Galvanized Steel is hot dipped in zinc - coated with a minimum 0.90 oz. of zinc per square foot. This gives the steel excellent corrosion resistance. Suitable for exterior applications.

HOT DIP GALVANIZED STEEL, known as ZINCGRIP® Steel, is continuously coated on both sides with a zinc coating. The hot dip process, pioneered by AK Steel, provides a tight metallurgical bond between the steel and the coating. This process results in a material with the strength and formability of steel plus the corrosion protection of zinc.
Zinc coating thickness on galvanized sheet has a linear relationship to service life and for building interior service, coating grade G-60, which has two-thirds the life expectancy of G-90, is consistent with anticipated building service life of 30 years. Base metal thickness is reduced as zinc coating is increased.

Evaluation of G60 vs G90 galvanizing with respect to cold formed metal framing (studs in exterior wall construction) and interior metal stud or other architectural components. Also for use in sheet metal work directly exposed to the elements.
The zinc coating not only serves as a barrier between the steel and the environment, it will sacrifice itself to protect the underlying steel sheet. Thus, the spread of corrosion from cut edges, drill holes, etc. is minimized. NS Wheeling-Nisshin minimized spangle is known in the industry for its excellent paintable, flat, uniform spangle free surface.
It is available on the full range of steel grades, Commercial Steel (CQ) through Extra Deep Drawing Steel (AKDQ) and is produced to ASTM specification A591 “Electrolytic Zinc Steel Sheets”. Chemical treatment (passivation) is available to retard zinc oxide or the surface can be phosphate coated (bonderized) to improve post painting adhesion.
That is, for G90, the coating on one square foot of sheet (total coating, both sides of the sheet) weighs a minimum of 0.90 ounces. If equally applied to both sides of the sheet, there would be a minimum of 0.45 ounces on each surface. The other measurement system in widespread use today is

zinc on the steel surface and is eed to represent the ounces per square foot of zinc as the total weight on both surfaces of the steel sheet. Minimum coating weights There are two coating weights used to specify zinc-coated steel doors and frames. In a coating
Introduction Coating Weight [Mass] Measurement Systems
for Zinc-Based Coatings on Steel Sheet 1.1 Rev 1.1 Mar-09 Introduction One of the most confusing aspects of coated steel sheet products are coating weight designations and what they mean, particularly with respect to product performance. This article is intended to clarify this issue. Coating Weight [Mass] Measurement Systems
Standard Specification for Steel Sheet, Zinc-Coated
1.1 This specification covers steel sheet, zinc-coated (galvanized) or zinc-iron alloy-coated (galvannealed) by the hot-dip process in coils and cut lengths. 1.2 The product is produced in various zinc or zinc-iron alloy-coating weights [masses] or coating designations as shown in Table 1
Batch Hot-Dip Galvanizing. Th e batch hot-dip galvanizing process, also known as general galvanizing, produces a zinc coating on iron and steel products by immersion of the material in a bath of liquid zinc. Before the coating is applied, the steel is cleaned to remove all oils, greases, soils, mill scale, and rust.
