Quality Policy Statement

We define quality as the degree to which our products or services meet or exceed our customers’ expectations as well as the level of service and professionalism achieved.

We are committed to promoting individual and collective responsibility for quality throughout all levels of our organization. We provide products and services that set the benchmark in their field.

As a minimum standard, galvanizing shall comply with AS/NZS 4680:2006 Hot – dip galvanised (zinc) coatings on fabricated ferrous articles.

To ensure that we document, monitor and continually seek to improve our performance or rectify substandard results, Albury Galvanizing operates a system based on AS/NZS ISO 9001: 2008 which provides the framework for our process of improvement.

To measure our performance, Key Performance Indicators (KPIs) are established at relevant functions and levels within the organization.

Coating Thickness

Thickness

The thickness of the galvanized coating shall conform with Table 1 and Table 2 in AS/NZS 4680:

Table 1:

REQUIREMENTS FOR COATING THICKNESS AND MASS FOR ARTICLES THAT ARE NOTCENTRIFUGED

Article Thickness (mm)Local coating thickness (Microns)Average coating thickness (Microns)Average coating mass (g/m2)(g/m2)
1.5mm or less 35 45 320
Over 1.5 to 3mm 45 55 390
Over 3 to 6mm 55 70 500
Over 6mm 70 85 600

Table 2:

REQUIREMENTS FOR COATING THICKNESS AND MASS FOR ARTICLES THAT ARE CENTRIFUGED

Article Thickness (mm)Local coating thickness (Microns)Average coating thickness (Microns)Average coating mass (g/m2)(g/m2)
Less than 8mm 25 35 250
8mm and over 40 55 390

The galvanized coating shall be sufficiently adherent to withstand normal handling during transport and erection.

Adhesion

The galvanized coating shall be continuous, adherent, as smooth and evenly distributed as possible, and free from any defect that is detrimental to the stated end use of the coated article. On silicon killed steels, the coating may be dull grey, provided the coating is sound and continuous. The integrity of the coating shall be determined by visual inspection and coating thickness measurements. Where slip factors are required to enable high strength friction grip bolting, where shown, these shall be obtained after galvanizing by suitable mechanical treatment of the faying surfaces. Where a paint finish is to be applied to the galvanized coating, this should be advised at the time of order and all spikes shall be removed and all edges shall be free from lumps and runs.

The thickness of the galvanized coating shall first be tested by the purchaser/designer at the galvanizer's works, using an approved magnetic measuring device. In the event of any dispute, an independent test shall be carried out in accordance with AS/NZS 4680, Appendix G.
