G30, G40, G60 AND G90:UNDERSTANDING ZINC-BASED COATING G30, G40, G60 AND G90:UNDERSTANDING ZINC-BASED COATING WEIGHTS EXECUTIVE SUMMARY Zinc-coated, or hot-dipped galvanized, steel is a widely used material in numerous applications, thanks to its corrosion-resistance, strength and relatively inexpensive cost.
GalvInfoNote Understanding Coating Weight Each coated-steel sheet product has a coating weight designation system that is in common use today. The system for each type of coating is defined in the appropriate ASTM standard. For example, the most commonly used ASTM standard is 653/A 653MA which covers hot-dip galvanized products. The coating
of the air knife as the steel exits the bath controls whether the coating is a G60 or a G210. Coating Designation All general galvanized coatings are produced the same way, in a > 98% pure zinc bath and have no specific coating designation. However, various steel products are galvanized with specific coating thickness minimums per ASTM) A123
HOT-DIP GALVANIZED (HDG) SHEET STEEL - McElroy G60 0.60 0.20 0.50 G40 0.40 0.12 0.30 G30 0.30 0.10 0.25 CORROSION PROTECTION HDG sheet steel protects well against corrosion. Figure 1 shows typical results of outdoor exposure testing on G90 HDG coated steel sheet. The length of time to red rust is proportional to the thickness of the zinc coating. For heavy gauge steel, thicker HDG
Hot Dipped Galvanized Rolled Steel Products « Rolled Hot Dipped Galvanized sheet or strip steel bathed in a molten solution containing not less than 98% pure zinc to uniformly coat for corrosion resistance.

Introduction Coating Weight [Mass] Measurement SystemsEach coated steel sheet product has its own coating weight designation system, which is defined in the appropriate ASTM standard. For example, the most widely used ASTM metallic-coated sheet standard is A 653/A 653M, which covers hot-dip galvanized products. One of the coating
Know your Microns - Hot Dip Galvanized Steel Coating When it comes to the specification of hot dip galvanizing, most contractors know that to be standards compliant, 7mm steel requires an average coating thickness of 85 microns. It is a simple industry standard that is easy to retain and is applicable to many construction needs.
A normal steel sheet will rust almost immediately, but galvanizing will protect the steel. This galvanized, eltro-coated, hot-dipped process produces a silvery look or spangled finish. As a standard, several of our industrial metal siding, metal roofing, metal decking, corrugated metal panels and accessories are made in galvanized steel 5.
Regular Spangle Hot Dipped Corrugated Galvanized Steel A normal steel sheet will rust almost immediately, but galvanizing will protect the steel. This galvanized, eltro-coated, hot-dipped process produces a silvery look or spangled finish. As a standard, several of our industrial metal siding, metal roofing, metal decking, corrugated metal panels and accessories are made in galvanized steel 5.
What does it mean to "Satin Coat Steel"Jan 09, 2012 · The sheet steel is passed through a molten zinc bath, emerging with a thin layer of zinc on either side. Upon cooling, zinc becomes extremely hard and protects the steel from corrosion. Common uses include ventilation ducts, cladding, and steel building studs. Galvalume This is sheet steel coated with 55% Aluminum-Zinc alloy by the hot-dip process.
