Din975 2 To 3M Galvanized Gr4.8 Length Long Threaded Rod Threaded Bar 25mm-6000mm Length
Description
Galvanization is a common method used to protect steel in corrosive conditions and galvanized reinforcing bars have been available for many years. The ASTM specification for galvanized reinforcing bars is ASTM A767/ A767M, Standard Specification for Zinc-Coated (Galvanized) Steel Bars for Concrete Reinforcement. Galvanized reinforcing bar may be ordered either as straight bars that are galvanized prior to fabrication or as bars that are galvanized after the bars have been fabricated. The A767/A767M specification provides for two coating weights, a Class 1 (3.50 oz/ft2) or Class 2 (2.00 oz/ft2). However, there are no guidelines concerning the use of Class 1 or Class 2, although most transportation agencies specify Class 1.
