In the event that the client has not submitted a request for quotation, the client shall state, upon delivery of the products to be hot dip galvanized or sherardized that a powder organic coating system is subsequently to be applied to these products. Requests for quotation shall also include the following: a) the class or classes of coating powders applied to the galvanized or sherardized steelwork — i.e. Class 1 or Class 2 of EN 13438; b) the size and weight of individual items being sent for processing (including dimensions and steel thickness); c) the coating powder colour and the gloss level required; NOTE This information is important to ensure consistency of appearance of the duplex coated articles with other work that might have been similarly specified for supply to site. d) the location of the site where the duplex coated articles are to be installed; e) the product standard required by the client for the duplex system. The required surface smoothness should be agreed prior to the work being carried out. 4.3 Information provision The information provided by the client to the galvanizer shall be in accordance with Annex A and EN ISO 1461. The information provided by the client to the sherardizer shall be in accordance with Annex A and EN ISO 17668 (stating the class of sherardized coating or minimum coating thickness required). The client shall inform the applicator of the relevant specifications (and / or parts thereof) to be applied with regard to corrosion testing on the finished articles. SIST EN 15773:2018
EN 15773:2018 (E) 12 The client shall inform the applicator of the corrosion category the products to be treated will be exposed to, in accordance with ISO 9223 or EN ISO 14713-1. The client shall inform the purchaser of the steel that the steel will have a duplex coating applied and that the duplex system will include hot dip galvanizing or sherardizing. NOTE See 5.1, Annex B and EN ISO 14713-2 for guidance on the influence of steel chemistry on surface characteristics of the galvanized article. The client shall inform the applicator whether in the specification protective coatings are prescribed. The client shall make such specifications available for the applicator before or at the time of the request for quotation. The client shall inform all parties about the intended use of the product. 4.4 Delivery of product prepared for coating The responsibilities for provision of work with the required surface condition (immediately prior to pre-treatment for application of a powder organic coating) shall be agreed between the client and the galvanizer / sherardizer and applicator. NOTE Correct selection of the steel is important to enable provision of the required surface condition of the galvanized work (see Clause 5, Annex A and Annex B). 5 Fabrication 5.1 Surface condition of the steel The surface condition of the steel article sent for galvanizing or sherardizing (and then for application of powder coating) has a significant effect on the surface quality of the finished product. In order to achieve optimum results from the application of duplex systems, a number of characteristics of the steel substrates require attention at the earliest stages of the fabrication process (see 5.2 to 5.4 for requirements and Annex A). NOTE For guidance on design and fabrication for galvanizing, see EN ISO 14713-2. For Guidance on design and fabrication for sherardizing, see EN ISO 14713-3. 5.2 Nature and composition of the raw material The steel shall be free of any laps and irregularities such as rolling blisters and rolling faults, in accordance with the standard terms and conditions of delivery in relation to the surface quality of steel (e.g. EN 10021, EN 10163-1, EN 10163-2, EN 10163-3 and EN 10221). 5.3 Welds, markings, labels The fabricator should ensure that all welds are sufficiently robust to withstand the stresses associated with the hot dip galvanizing, sherardizing and powder coating operations. Welds shall be free of welding spatter, welding slag and welding oxides. Welding spatter, welding slag and welding oxides shall be removed by appropriate methods such as blasting, grinding, sanding, de-scaling and/or brushing. Unless otherwise agreed, welds used in the fabrication of the article shall be smooth and continuous and shall conform to Level D in accordance with EN ISO 5817. NOTE 1 Welds might appear raised after galvanizing unless weld filler metal is used that matches the parent steel. Any welding spray applied shall be free of silicones and be water soluble. SIST EN 15773:2018
EN 15773:2018 (E) 13 Residual welding spray should be removable using the standard pre-treatment used at the galvanizing plant. The construction parts to be delivered to the galvanizing / sherardizing plant shall be suitable for that process and in particular be free of markings applied in paint, varnish, stickers and/or inks. NOTE 2 For further information regarding galvanizing, see EN ISO 1461 and EN ISO 14713-2 and for further information regarding sherardizing, see EN ISO 17668 and EN ISO 14713-3. 5.4 Deviations of edges and sides In order to prevent mechanical damage to the zinc coating and the possible development of insufficient coating of the edges and sides with powder organic coating systems, all trimming, cutting, punching, drilling and other operations likely to damage the article shall be carried out prior to galvanizing unless repairs are carried out in accordance with guidance set out by the powder manufacturer (see also 6.2). Burrs at holes or along edges shall be removed prior to galvanizing. Any trimming, punching, sawing, cutting (including laser cutting, plasma cutting or similar methods which produce very sharp edges) and welding edges shall be chamfered to at least 1 mm or, preferably, rounded to a minimum of 2 mm. NOTE Perforated sheet and stretched steel does not as a rule fulfil this requirement. The capability to protect the perforated sheet and stretched steel will therefore be reduced. 6 Zinc coating and zinc surface 6.1 Cooling Unless otherwise agreed the hot dip galvanized products, after hot dip galvanizing, shall be air-cooled (see Annex C). NOTE Air-cooling is part of the sherardized process. 6.2 Quality and inspection of the zinc coating The requirements for the quality and inspection of the zinc coating depend on the type of zinc coating process used, for example: a) zinc coatings of hot dip galvanized products in accordance with EN ISO 1461; b) zinc coatings for steel tubes, applied in automatic installations in accordance wit

Introduction
In order to achieve a duplex system which satisfies the many varied aesthetic and performance
requirements currently in existence in the marketplace, the following aspects of the supply and
application of the systems should be controllable:
— fabrication and composition of the material (Clause 5);
— the zinc coating (Clause 6);
— surface smoothing for coating (Clause 6);
— environmental conditions during storage, transport and application (Clause 6);
— the pre-treatment of the zinc surface (Clause 7);
— instructions provided by chemical pre-treatment suppliers (Clause 7), powder manufacturers
(Clause 8);
— the organic coating system (Clause 8);
— packaging, storage and movement of finished products (Clause 9);
— installation (Clause 10);
— inspection (Clause 11).

1 Scope
This European Standard specifies the agreements to be made between the client, the galvanizer/
sherardizer, the chemical suppliers and the applicators of the pre-treatment and the powder organic
coating systems (if they are not one and the same). It also specifies the quality of the galvanized or
sherardized articles to which the powder organic coatings are to be applied and for the pre-treatment
and powder organic coatings intended for application to the galvanized or sherardized articles.
This standard applies to the application of hot dip galvanized, sherardized and powder organic coatings
by controlled industrial processes to articles consisting of or manufactured from steel. The standard
applies to hot dip galvanized products, galvanized in accordance with EN ISO 1461 and EN 10240, or
products sherardized in accordance with EN ISO 17668, as well as parts of these products
manufactured from continuously galvanized sheet and strip galvanized in accordance with EN 10346
which, after the galvanizing and/or assembly or sherardizing, will have a powder organic coating
system applied. This standard also applies to products which have been hot dip galvanized or
sherardized according to specific product standards to which powder organic systems are applied.
This standard might also be useful when supplying other organic coating systems (excluding wet paint
systems).

5 Fabrication
5.1 Surface condition of the steel
The surface condition of the steel article sent for galvanizing or sherardizing (and then for application
of powder coating) has a significant effect on the surface quality of the finished product. In order to
achieve optimum results from the application of duplex systems, a number of characteristics of the steel
substrates require attention at the earliest stages of the fabrication process (see 5.2 to 5.4 for
requirements and Annex A).
NOTE For guidance on design and fabrication for galvanizing, see EN ISO 14713-2. For Guidance on design
and fabrication for sherardizing, see EN ISO 14713-3.
5.2 Nature and composition of the raw material
The steel shall be free of any laps and irregularities such as rolling blisters and rolling faults, in
accordance with the standard terms and conditions of delivery in relation to the surface quality of steel
(e.g. EN 10021, EN 10163-1, EN 10163-2, EN 10163-3 and EN 10221).
