Yes. Coating steel with zinc through the hot-dip galvanizing process protects it from corrosion, with minimal environmental, economic and social impacts. Not only does hot-dip galvanizing provide decades of maintenance-free longevity, but its primary components, zinc and steel, are natural, abundant, and 100% recyclable, making hot-dip galvanized steel an infinitely renewable building material.
Depending on the product mix, square feet per ton, and condition of the steel surface, galvanizing is often less expensive on an initial cost basis. However, as with any purchase, the lifetime costs should be considered when making a project decision on the corrosion prevention system to utilize. And, with galvanizing, the life-cycle cost, i.e. the cost per year to maintain, is almost always less than a paint system. Paint systems require maintenance, partial repainting, and full repainting several times over a 30-year project life. The costs can be staggering, making the decision to paint a costly one in the long run.
Yes. Corbec uses standards and processes that meet the specifications for hot-dip galvanizing issued by the Canadian Standards Association (CSA) and the American Society for Testing and Materials (ASTM). The test results and certificates of compliance for selected specifications are also available, provided the request is made on the original order, delivered before galvanizing.
There are limits to the size of piece that can be accommodated in our kettles, however, it is best to contact us and we can discuss options and solutions. Double-dipping is a progressive immersion procedure for parts that are too large for in a single dip in the kettle. This procedure cannot be used to obtain additional coating.
