Nordic Galvanizers’ technical delivery conditions for hot-dip galvanizing as contract work Oktober 2017

1.0 Liability in damages 1.1 The hot-dip galvanizer (”HDG”) will take well care of the items delivered for hot-dip galvanizing or other treatment and give them a professionally correct treatment. 1.2 HDG will exercise the attention and care required but assumes no responsibility to treat items the condition of which is such that they will be damaged or cause damage during treatment, without HDG’s knowledge. 1.3 The instructions as to which requirements to be made of items to be hot-dip galvanized are available in Danish Standards - DS/EN ISO 1461:2009 which includes specific information about...

Need for or acceptance of hot-dip galvanizing being performed in centrifuge plants and Additional treatment or coating, if any, to be applied to the zinc surface after hot-dip that the coating thereby complies with the requirements specified in Table 4. galvanizing. k. Inspection measures. 2.2 By request, HDG must submit the relevant information in HDG’s possession, including information about the method of repairing un-coated areas. 2.3 All references above refer to special sections and notes of DS/EN ISO 1461:2009. – Individual quotations may contain deviations from the standard. 2.4 Such deviations...

galvanizing. – Internal as well as external threads cannot be expected to be threadable after hot-dip galvanizing. 7.0 Coverage 7.1 Any surface part which is not to be hot-dip galvanized must be clearly specified in the order and in the Customer’s delivery note. 7.2 Coverage of such surfaces will be performed at a surcharge. 7.3 However, the location or extent of a surface may hinder its effective coverage. 8.0 Additional cleaning 8.1 All materials must be free from paint, lacquer, grease, oil, pitting, zinc or other impurities and products which cannot be removed in a standard staining process....

11.0 Material changes 11.1 The Customer is responsible for changes in the item’s materials, e.g. aging or other brittleness caused by the material’s reaction during the treatment. 11.2 Please note that in hot-dip galvanizing of steel with a tensile strength of 1000 N/mm2 or above, hydrogen embrittlement may occur which is why such materials should not be treated in a contract galvanizing plant. 11.3 Please note in particular that flame / plasma cutting or laser cutting of edges will affect the silicon content which is why HDG does not guarantee the film thickness and adhesion to these, see DS/EN...

16.0 The material’s suitability for hot-dip galvanizing 16.1 The Customer is responsible for the steel types and steel composition being suitable for hot-dip galvanizing to ensure that the target quality can be achieved in a normal, routine immersion process (without extended immersion times). The Customer selects the steel and material design according to DS/EN ISO 14713 (2010). 16.2 In hot-dip galvanizing of aluminium-calmed steel with a low content of silicon (Si <0.03 w%), it can be very difficult to meet the requirements for film thickness, even at extended immersion times in the molten...
