Before you start

These are the things you need to know

Consider this

When designing and fabricating steel for the hot-dip galvanizing process, certain considerations must be taken into account. Communication between the architect/engineer, the fabricator and the galvanizer will ensure everyone is on the same page and has a complete understanding of what will be happening. By adopting these practices, in conjunction with the standards in ASTM A 385 for Providing High Quality Zinc Coatings, you will ensure your expectations are met and achieved.

Sustainable development is the social, economic and environmental commitment to growth and development that meets the needs of the present without compromising future generations to meet their needs. It is a vital aspect of the present and future built environment. Hot dip galvanized steel is uniquely positioned to contribute to building a sustainable future. Coating steel with zinc in the hot-dip galvanizing process protects steel from corrosion with minimal environmental, economic or social impacts.

The energy input over the life of hot dip galvanized steel is, in fact, less than half of painted steel. There is no energy, material or labor input for maintenance throughout a project’s lifetime. The global warming potential (CO2) of hot dip galvanized steel is 1/3, and the acidification potential (SO2) is less than half of painted steel.

LEED is the nationally accepted benchmark for the design, construction and operation of high performance green buildings. LEED promotes a whole building approach to sustainability by recognizing performance in key areas of human health and environmental impacts. With more than 70% combined recycled content, hot dip galvanized steel easily meets requirements of Credits 4.1 and 4.2 of the Materials and Resources Credit.

The durable corrosion protection of steel by coating it with naturally occurring zinc metal is unmatched in terms of safe and economical construction material. With hot dip galvanized steel being 100% recyclable, it is the most sustainable choice to protect our infrastructure!
