Conforms to : ASTM A792, , JIS G3321, AS1397. This is an absurd number for the coating thickness, because the coating is a thing flexible film, hardly noticeable on the fabric. Follow the line of the chart for the type and weight of paper you wish to convert until you find the column that states the gsm for that type. Conversely, for every 1 gram per square metre of coating, you get 0.14 microns of thickness: 1 gram per square metre = 0.14 microns thick This uniformity of the zinc thickness is typically given within a batch on the supplied sheet that still has to be formed. Gsm is g/m². High tensile strength of 550 MPA. So then a 1 micron thickness translates to 7.14 g/m^2. Volume of zinc coating (total) 0.048 cm3. The galvanized coating shall be continuous, adherent, as smooth and evenly distributed as possible, and free from any defect that is detrimental to the stated end use of the coated article. 2. 5 micron powder 93 *with 100 psi. When the body parts are formed, flowing or even scraping off of the zinc coating may occur in the areas of severe bending radii, and this may vary thickness by 3 and 9 microns, and occasionally remove the coating altogether. •Pre- Printed Galvanized Steel Sheet (GI Base) Zinc coating: Z 120 GSM Primer service coat : 5 micron epoxy/ PU on both sides Paint coating : Regular Modified Polyester (RMP) (Optional – SiliconModified Polyester & PVF 2) Painting thickness (top) : 18-20 Microns. Yield Strength : 345-550 MPa. “The CGR process has lower thickness thereby saving up on zinc while 350 GSM coating increases steel life. On silicon killed steels, the coating may be dull grey, which is acceptable provided the coating is sound and continuous. China 15/7 Micron Paint Zinc 40GSM PPGI Coils for Roofing, Find details about China PPGI Coils, PPGI from 15/7 Micron Paint Zinc 40GSM PPGI Coils for Roofing - … The life expectancy of zinc coatings is independent on the coating process – an equivalent coating of zinc will provide the same life expectancy regardless of the coating process. Therefore: 0.45 oz/ft2 x 1.684 = 0.76 mils per side; 0.45 oz/ft2 x 42.78 = 19 microns per side Zinc phosphate coatings can be higher and may run from 50 to 125 mg/ft 2 or 0.5–1.4 g/m 2. Taking a density for polyurethane elastomer of 1.2 g/cm3, 1500 grams per metre would be a 1260 micron thick coating (rounding). Galvanization or galvanizing (also spelled galvanisation or galvanising) 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 the parts are submerged in a bath of molten hot zinc. If you know the material density, multiply density by thickness and adjust the prefixes. 1 metre is equal to 1000000 micron, or 1.0E-9 Gm.
