Environmental assessment of photovoltaic bracket hot-dip galvanizing project

What is hot-dip galvanized steel?

Hot-dip galvanizing is a proven steel corrosion protection system that transcends time with little economic or environmental impact. From artful sculptures and building facades to utilitarian bridges, utility poles, and other infrastructure, hot-dip galvanized steel is an important part of everyday life.

Why should you choose hot-dip galvanizing?

Once considered only as a means of corrosion protection, hot-dip galvanizing is now specified for an array of reasons including lower initial and life cycle costs, durability, longevity, availability, versatility, sustainability, and aesthetics.

Does hot-dip galvanising protect steel structures from corrosion?

The durability of protection depends on the zinc layer thickness and the environmental exposure conditions (Kovalev et al., 2019). The hot-dip galvanising (HDG) method is one common and effective solution to protect steel structures from corrosion.

How can the galvanisation sector reduce its environmental impacts?

Thus, one important challenge of the galvanisation sector, is to reduce its environmental impacts linked to the intensive use of energy and resources. 1.2. The hot-dip galvanising process and life cycle assessment In the literature, the environmental assessment of steel production has been studied using tools such as life cycle assessment (LCA).

Is hot-dip galvanized steel a sustainable building material?

Not only does hot-dip galvanizing provide decades of maintenance-free longevity, its primary components, zinc and steel, are both 100% recyclable, making hot-dip galvanizing an infinitely renewable building material. Sustainability and corrosion protection are intrinsic whenever hot-dip galvanized steel (HDG) is used.

What is a hot-dip galvanisation process?

System description of the hot-dip galvanisation process in scenarios 1 and 2. Within the HDG process the main stages were degreasing, pickling, fluxing, drying, immersion in the molten zinc bath and centrifugation (Ortiz et al., 2004). The main raw materials inputs are primary zinc and hydrochloric acid.
