In the unlikely event of being unable to identify the correct clause for a particular galvanizing application, please contact Galvanizers Association for specific advice.

A Guide to Hot Dip Galvanizing Standard EN ISO 1461 : 2009

Isp European and International standard covering post-fabrication hot dip galvanizing of steelwork I. The galvanizer acts io a specialist subcontractor to a steel fabricator and, as such, his contractual relationship is with the fabricator, not with the ultimate user.

FAQs How long does galvanizing last? If the control ample meets the surface finish and coating thickness requirements of I. If this second control sample fails to meet standard requirement, then the lot is rejected. For structural steelwork, it is advisable to ascertain whether thicker coatings could be achieved through their greater section thickness and without grit blasting.

Specification of thicker coatings must only be made following consultation with the galvanizer concerning filehype and the means by which they will be achieved.

Details of coating thicknesses requirements are given in Filteype 3 and 4. 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.

The coating should withstand, without peeling or flaking, handling consistent with the nature and thickness of the coating and is 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.

Guidelines for painting galvanized steel Powder coating galvanized steel. 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. To ensure the best quality and technical back-up service, it should be fiiletype that the work be “processed by a member of Galvanizers Association”.

It should however, be emphasised that for most applications, thicker coatings are rarely necessary. The standard excludes products processed by an automated process such as sheet, wire and tubes.

In addition, the standard has no aesthetic requirements and consequently variation in coating appearance is permissible. Especificaciones y Mtodos de iso filetype pdf. The standard encourages coating thickness to be determined by non-destructive methods such as filehype use of a magnetic coating thickness gauge ISO although the Gravimetric Test ISO which is a destructive method remains the referee test in cases of dispute.

Coating thickness requirements are given in terms of Local average coating thickness requirements relating to single reference filteype and Average coating thickness relating to the whole article.

As coating life expectancy figures quoted are based on the minimum coating thickness they are therefore usually very conservative. However, there are some exceptions to this standard see thicker coatings below.

How can I connect steelwork? If a control sample fails to meet coating thickness requirements, then double the original control sample size is taken for testing and if this meets standard requirements then the lot as a whole fioetype accepted.

ISO EN ISO Standard Galvanizing Specifications

This is an important advantage of the galvanizing process; a standard coating thickness is applied almost automatically. The coating does not need to be perfectly smooth and some surface unevenness is permissible. For articles in categories B-D the average coating thickness in each reference area should meet the Local Average Coating Thickness Requirement.

Achieving thicker coatings through specification of a reactive steel is normally only appropriate for specific applications. There are many references to specifying hot dip galvanizing throughout the National Building Specification NBS system, the main location being G10 — Structural steel framing. Iso filetype pdf.

If larger areas are present, the article should be regalvanized unless a repair is agreed within the supply chain.

The galvanized coating should be continuous, relatively smooth and free from flux staining. In addition, it also gives guidance upon the number of areas in an individual article from which batches of coating thickness measurements should be taken Table 2. The standard permits repair on uncoated areas up to 10 cm 2 in size with the total areas for repair not exceeding 0. 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.

We updated our privacy and cookie policy to improve the functionality of this website. Initially a visual inspection is conducted to access surface finish. General guidance on corrosion protection is also given. For articles in category A the average coating thickness in each reference area should meet the Average Coating Thickness Requirement. How to ensure a good design? In effect this means no areas of an article should have an average coating thickness below the Local average coating thickness requirement while the average thickness over the whole of the article should meet the Average coating thickness.

The actual thickness of galvanized coating achieved varies with steel section size, surface profile and surface composition. Actual coating weights are often much more than the minimum specified in the standard.

The standard states that at present no suitable International adhesion test exist for hot dip galvanizing and so where testing isp required this should be agreed within the supply chain and reaffirms that such testing is not normally filetjpe as good adhesion, or more correctly, cohesion, is a characteristics of the coating.
