The coating 11461 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.

Especificaciones y Mtodos de iso filetype pdf. The standard then lays down a post-galvanizing inspection regime indicating the minimum number of samples which should be taken for inspection based fietype the size of the lot galvanized Table 1.

The presence of zinc corrosion products known as filefype 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. In accordance with Adobe’s licensing policy, this file may be printed or viewed but shall not filetyp edited unless the typefaces which are embedded are licensed to and installed on the computer performing the editing.

The basic specification for hot dip galvanized coatings on iron and steel articles diletype defined by a single standard, EN ISO Hot dip galvanized coatings on iron and steel articles specifications and test methods. The coating does not need to be perfectly smooth and some surface unevenness is permissible.

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

The standard excludes products processed by an automated process such as sheet, wire and tubes. Design for galvanizing Joining galvanized steel Nuts and bolts.

Iso 1461 filetype pdf

Iso filetype pdf. 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. How to ensure a good design? A certificate of compliance ISO would filetyep be available confirming that the work processed met the requirements of I.


However, there are some exceptions to this standard see thicker coatings below. The European and International standard covering post-fabrication hot dip galvanizing of steelwork I.

ISO EN ISO Standard Galvanizing Specifications

Filletype articles in categories B-D the average coating thickness in each reference area should meet the Local Average Coating Thickness Requirement. Initially a visual inspection is conducted to access surface finish. For articles in category A the average coating thickness in each reference area should meet the Average Coating Thickness Requirement.

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”. The standard permits repair on uncoated areas up to 10 cm 2 in size with the total areas for repair not exceeding 0.

There are many references to specifying hot dip galvanizing throughout the National Building Specification NBS system, the main location being G10 — Structural steel framing. How much does galvanizing cost?

In addition, the standard has no aesthetic requirements and consequently variation in coating appearance is permissible. The actual thickness of galvanized coating achieved varies with steel section size, surface profile and surface composition. However, there are some exceptions to this standard see thicker coatings below. When hot dip galvanizing is specified, the surface of the steel is completely covered with a uniform coating fileype thickness is determined filetyp by the thickness of the steel being galvanized see Graph 1 below.


Filetypf 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. Details of coating thicknesses requirements are given in Tables 3 and 4. This is an important advantage of the galvanizing process; a standard coating thickness is applied almost automatically.

Achieving thicker coatings through specification of a reactive steel is normally only appropriate for specific applications. The standard states that at filwtype no suitable International adhesion test exist 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 more correctly, cohesion, is a characteristics of the coating.

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

FAQs How long does galvanizing last? How can I connect steelwork? The standard encourages coating thickness to be determined by non-destructive methods such as the 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.

General guidance on corrosion protection is also given. If this second control sample fails to meet standard filetypw, then the lot is rejected. In addition, it also gives guidance upon 14611 number of areas in an individual article from which batches of coating thickness measurements should be taken Table 2.

Specification of thicker coatings must only be made following consultation with lso galvanizer concerning viability and the means by which they will be achieved. As coating life expectancy figures quoted are based on the minimum coating thickness they are therefore usually very conservative.

Actual coating weights are often much more than the minimum specified in the standard. Guidelines for painting galvanized steel Powder coating galvanized steel.
