Details of coating thicknesses requirements are given in Tables 3 and 4. It should however, be emphasised that for most applications, thicker coatings are rarely necessary. However, there are some exceptions to this standard see thicker coatings below.

Iso filetype pdf

Specification of thicker coatings must only be made following consultation with the galvanizer concerning viability and the means by which they will be achieved. For articles in category A the average coating thickness in each reference area should meet the Average Coating Thickness Requirement. In the unlikely event of being unable to identify the correct clause for a particular galvanizing application, please contact Galvanizers Association for specific advice.

The standard states that at present no suitable International ido test filetyppe for hot dip galvanizing and so where testing is required this should be agreed within the supply chain and reaffirms that such testing is not normally necessary as good adhesion, or jso correctly, cohesion, is a characteristics of the coating. We updated our privacy and cookie policy to improve the functionality of fileetype website. The standard excludes products processed by an automated process such as sheet, wire and tubes.

The standard then lays down a post-galvanizing inspection regime indicating the minimum number of samples which should be taken for inspection based upon the size of the lot galvanized Table 1.

EN ISO 1461

Achieving thicker coatings through specification of a reactive steel is normally only appropriate for specific applications. The standard permits repair on uncoated areas up to 10 cm 2 in size with the total areas for repair not exceeding 0.


Actual coating weights are often much more filftype the minimum specified in the standard. How can I connect steelwork?

If this second control sample fails to meet standard requirement, then the lot is rejected.

The galvanizer acts as a specialist subcontractor to a steel fabricator and, as such, his contractual relationship is with the fabricator, not with the ultimate user. To ensure the best quality and technical back-up service, it should be stated that the work be “processed by a member of Galvanizers Association”.

In addition, it also gives guidance upon filetpe number of areas in an individual article from which batches of coating thickness measurements should be taken Table 2. In accordance with Adobe’s licensing policy, this file may be printed or viewed but shall not be edited unless the typefaces which are filetyoe are licensed to and installed on the computer performing the editing.

Coating thickness requirements are given in terms of Local average coating thickness requirements relating to single reference areas and Average coating thickness relating to the whole article. FAQs How long does galvanizing last? The European and International standard covering post-fabrication hot dip galvanizing of steelwork I. A certificate of compliance ISO would normally be available confirming that the work processed met the requirements of I. How much does galvanizing cost?

The actual thickness of galvanized coating achieved varies with steel section size, surface profile and surface composition. The coating should withstand, without peeling or flaking, handling consistent with the nature and thickness of the coating and normal use of the article although it should be appreciated that thicker coatings may require more careful handling and that bending after galvanizing is not considered normal handling.

How to ensure a good design?

Especificaciones y Mtodos de iso filetype pdf. The basic specification for hot dip galvanized coatings on iron and steel articles is defined by a single standard, EN ISO Hot dip galvanized coatings on iron and steel articles specifications and test methods. In addition, the standard has no aesthetic requirements and consequently variation in coating appearance is permissible.


Guidelines for painting galvanized steel Powder coating galvanized steel. The presence of zinc corrosion products known as wet storage stain formed if the coating becomes damp and is unable to fully dry out is also not grounds for rejection provided the coating meets the local average coating thickness requirements see Table 3 and 4. Design for galvanizing Joining galvanized steel Nuts and bolts. When hot dip galvanizing is specified, the surface of the steel is completely covered with a uniform coating whose thickness is determined principally by the thickness of the steel being galvanized see Graph 1 below.

For structural steelwork, it is advisable to ascertain whether thicker coatings could be achieved through their greater section thickness and without grit blasting.

As coating life expectancy figures quoted are based on the minimum coating thickness they are therefore usually very conservative.

If the control ample meets the surface finish and coating thickness requirements of I.
