Galvanized Steel Sheet Specification

The basic specification for hot dip galvanized coatings on iron and steel articles is defined by a single standard en iso 1461 hot dip galvanized coatings on iron and steel articles specifications and test methods.

Galvanized steel sheet specification.

1 2 the product is produced in various zinc or zinc iron alloy coating weights masses or coating designations as shown in table 1 and in table s2 1. However there are some exceptions to this standard see thicker coatings below. The number immediately following the designation indicates the year of original adoption or in the case of revision the year of last revision. The zinc iron alloy layers formed during the process of galvanising create a protective coat around the steel keeping moisture out and preventing corrosion.

Standard specification for steel sheet metallic coated by the hot dip process and prepainted by the coil coating process for exterior exposed building products. Astm a123 standard specification of zinc hot dip galvanized coatings on iron and steel products refers to products fabricated and then hot dip galvanized using the batch process. Standard specification for steel sheet zinc coated galvanized or zinc iron alloy coated galvannealed by the hot dip process. Standard specification for steel sheet zinc coated galvanized or zinc iron alloy coated galvannealed by the hot dip process1 this standard is issued under the fixed designationa653 a653m.

These measurements are based on astm a924 924m 94 standard specification for general requirements for sheet steel metallic coated by the hot dip process formerly astma525. A792 a792m 10 2015. The method as specif relevant iso standard 111ay also be followed as an alternate method. And astma653 a653m 94 standard specification for sheet steel zinc coat galvanized or zinc iron alloy coated galvanized by the hot dip process.

The galvanised steel we make is not just high in strength but also corrosion resistant eco friendly durable and lightweight. For all tests specified in this standard chemical physical others. Astm a767 standard specification for zinc coated galvanized steel bars for concrete reinforcement covers zinc coatings applied by the hot dip process on individual steel reinforcing bars before fabrication used in concrete. The two methods of hot dip galvanizing batch and continuous produce very different products with different characteristics.
