Foreword

GB/T 19355 "zinc layer covering the steel structure corrosion prevention guidelines and recommendations" is divided into three parts. --- Part 1. Design and basic principles of corrosion; --- Part 2. Hot dip galvanizing; --- Part 3. infiltration of zinc powder. This section GB/T 19355 Part 1. This section drafted in accordance with GB/T 1.1-2009 given rules. This portion instead of GB/T 19355-2003 "corrosion protection of steel structures - Zinc and aluminum coatings - Guidelines" corrosion resistant part of the design, compared with the GB/T 19355-2003, in addition to editorial changes, the major technical changes are as follows . --- The name of the standard was changed to "zinc coating layer steel structure corrosion prevention guidelines and recommendations Part 1. Design and corrosion of the basic principles"; --- Original mixed hot dip galvanized, zinc powder infiltration separate chapters, put forward the basic principles of the zinc coating layer design and corrosion. This section uses redrafted Law Amendment uses ISO 14713-1.2009 "Steel Structure Zinc Coatings corrosion guidelines and recommendations Part 1. General Principles for Design and corrosion." This part of ISO 14713-1.2009 compared to the main differences are as follows. --- For ease of use, this part of the normative references and references used in our country has equivalent or modify the international standards of national standards. This part is proposed by China Machinery Industry Federation. The portion of the layer Standardization Technical Committee (SAC/TC57) administered by the National Metal and non-metal cover.

1 Scope

GB/T 19355 in this part of the anti-corrosive zinc coating layer structure is exposed to different environments used by the proposed grade and corrosion resistant design guidelines and recommendations. The initial protection related to. --- Workable standard process; ---Design requirements; --- Environment. This section applies to a zinc coating layer obtained by the following process. a) hot-dip galvanizing layer (hot-dip galvanized parts); b) hot-dip galvanizing layer (continuous hot-dip galvanized steel); c) infiltration of zinc powder layer; d) thermal spray coatings; e) coating machine; f) electro-galvanized layer. These guidelines and recommendations do not involve galvanized steel corrosion in service maintenance. Guide to this issue can be found in ISO 12944-5 and ISO 12944-8. Note. all kinds of product-related standards (such as nails, fasteners, ductile iron pipe, etc.), the zinc coating system put forward specific requirements, which exceed the general guidelines in this section of this standard proposed. These requirements for specific products, priority should be given to the general guidelines.
