ISO 14657:2005 PDF Download

ISO 14657:2005 is a standard that outlines the requirements for the hot-dip zinc coating on steel reinforcement materials used to reinforce concrete. The standard categorizes the coatings into three classes: class A, class B, and class C, with each class having different coating mass specifications. This classification ensures that the zinc coating meets specific criteria in terms of its thickness and durability.

It is important to note that this standard does not cover hot-dip zinc-coated reinforcements used for prestressing purposes or their components. The purpose of ISO 14657:2005 is to provide a guideline for the galvanizing process of steel reinforcement materials in order to enhance their corrosion resistance and increase their lifespan when used in concrete structures.
