This recommendation comes from the pressure treated wood industry themselves based on performance testing. It looks like you are visiting from the UK. Points to Remember: With Galvanize coated steels, contact with lead or copper must be avoided (including products containing lead or copper such as pressure treated lumber) as it can result in accelerated corrosion. **Note: ... Galvanized Steel Industrial Metal Sheets & Flat Stock, Galvanized Steel Metals & Alloys, Stainless Steel Sheet 48, The steel is coated with Zinc by the hot-dip process in accordance with ASTM A 653. G90 Galvanized Steel Sheet - (ASTM A527/A653) Galvanized Steel Sheets are intended for usewhere greater corrosion protection is required without painting. The two methods of hot-dip galvanizing, batch and continuous, produce very different products with different characteristics. Galvanized sheet metal and coils have high machinability making it easy to level, shear, and laser cut them to size. The sheet coating thicknesses must be divided by two for an approximate comparison. Fax: 720.554.0909, General Information Hi Big Builders, We have a guillotine, so we can cut your selected sheet into any combination of pieces. 25,000-35,000 ** All values are minimum and are representative. However, the coating thickness difference is significant. About 92% of these are steel sheets, 1% are stainless steel sheets, and 1% are roof tiles. Galvanized G90 Flat Sheet. GAL185.500 : 18 GAUGE X COIL G90 : LB Log in to View Price. Galvanized G90. Example: G235 has approximately 2.12 mils per side. These coating weights are a total for both sides of the strip. Hi Nguyen, FLAT SHEET Metal Sales PVDF pre-painted, Galvanized Steel provided in Flat Sheet is intended for general sheet metal use in build-ing construction. In addition, Galvanize coated steels are not recommended (or require additional zinc coatings and/or paint to limit corrosion) for applications near seawater (chlorides accelerate corrosion) or other harsh corrosive environments which have heavy exposure to corrosive chemicals (such as caustic soda, ammonia, lime, hydrochloric acid, nitric acid, hydrogen sulfide, sulfuric acid, sulfur dioxide), or excessive water contact with wet materials or standing water. For example, the most commonly used ASTM standard is A 653/A 653M, which covers hot-dip galvanized … The material provided herein has been developed to provide accurate and authoritative information about after-fabrication hot-dip galvanized steel.

They may be bent flat upon themselves (within accepted bend radii) in any direction at room temperature without cracking. SKU: PL1648120 . *Mn – .60 Max. Furthermore, batch hot-dip galvanizing provides a significantly thicker zinc coating and therefore a longer service life.
