Hot-Dip Galvanizing As Corrosion Protection Method

Enormous economic challenges in the 21st century have brought tremendous needs to utilize available limited resources in the most efficient and effective ways. The impacts of globalization, currency devaluation, inflation, environmental concerns as well as massive natural disasters are changing governance at all levels.

Technological advances have enabled new ways of deploying services in timely and cost effective means. It has become very apparent that governance must be very strategic and the capacity to adopt technologies that would save cost especially in the long term is vital. Innovative technological applications drive efficiency, productivity and aid to enhance the quality of lives of citizens.

This technology should be durable, environmentally friendly as well as cost competitive. Over the years, many governments have made decisions to build and expand their infrastructures in order to be competitive in tourism, transportation and other key areas of the economy. Regrettably, governments have been slow to adopt and implement techniques to protect these facilities from corrosion.

As governments continue to focus on expanding militaries and managing political systems, budgetary allocations for expanding national infrastructures like bridges, dams, airports are expected to decrease despite increased levels of operations. To ensure that these facilities operate at optimal levels since building new ones are not immediate, efforts should be geared to preserve them using the most efficient corrosion protection method. This certainly affects all major economies: from Africa to North America.

Corrosion causes both economic and environmental problems and adequate techniques should be used to control it in facilities to ensure maximal service to the citizens. Adopting the right technological solution to the hazards of corrosion will arguably extend the usefulness of these facilities as well as help the state to save money in the long run. This will ultimately benefit everyone especially the taxpayers.

Presently, commonly used public corrosion protection techniques are painting and plating. These techniques though partially effective are not state of the art. They fail to deliver long-term benefits, which taxpayers expect from their taxes. As an engineering student that has studied the effects of corrosion and how to minimize their impacts, I wish to suggest hot-dip galvanizing corrosion protection method as a technique of choice.

This method of corrosion protection is a method where a metal is used to “bath” the one that is being protected to form a bonded structure that prevents rust. It is a form of “chemical mechanical bathing” of the metal that enables the formation of metallic oxides that prevent corrosion. This corrosion protection technique has been proven to be reliable, cheap, and durable with less harm to the environment. The process of galvanizing (bathing a metal with metal to form oxides resistant to corrosion) from which hot dip galvanizing is made has existed for more than 250 years and has been a mainstay of the industry since the early 20th century. It is used in different manufacturing processes to produce steel with unmatched protection from the ravages of corrosion. From roofing nails to highway guardrail, to Brooklyn Bridges suspension and to NASA’s launch pad sound suppression systems, galvanizing has provided means to protect materials from corrosion successfully.
