Hot Dip Galvanizers Association Southern Africa

The Hot Dip Galvanizers Association Southern Africa (HDGASA) is a not-for-profit trade organization, founded in 1965, dedicated to serving the needs of end-users, specifiers, architects, engineers, contractors, fabricators and hot dip galvanizers throughout Southern Africa.

To further this aim, the Association provides advisory involvement, training and information by way of courses, workshops, specialized presentations on corrosion control, technical research papers and case studies of hot dip galvanizing’s effectiveness at corrosion control.

The Association liaises with regulatory and standards authorities governing the corrosion control and associated industries. 

The HDGASA provides services for independent inspection against relevant standards and reviewing compliance against the relevant standards by the stakeholders in the industry, and provides applicable analysis through metallurgical and SANAS approved analytical laboratories.

The Galvanizing Members of the HDGASA represent the majority of the Hot Dip Galvanizing fraternity both by mass and value in sub-Saharan Africa. Through close liaison with the EGGA, AGA, Australian Galvanizers and associated organizations the HDGASA maintains a global presence and participates in arenas of common interest including the ISO standards. 

The HDGASA publishes supporting literature such as our Steel Protection Guide, Design Wall Chart and Facts about Hot Dip Galvanizing. These are used effectively to bring third parties with little or no knowledge of Hot-Dip Galvanizing up to speed with the technology.
