What is galvanized steel? In today’s world, galvanized objects are all around us. Next time you see a staircase, stop sign, ladder, nail, bridge, bench, bucket, pipe, car part, building, structure, or storage container, know that it’s probably galvanized. And with good reason. The iron in steel is prone to oxidize. Without a layer of protection, or galvanization, steel will rust.
So, what exactly is galvanization? It is the process of applying a coat of zinc to steel for corrosion protection. The zinc acts as a protective barrier for the steel, prolonging its life, reliability, and uniformity. Above all, it helps prevent rust and wear. Some objects and structures made with galvanized steel may not need maintenance for 40-50 years! This is certainly not the case with bare or untreated steel. In essence, galvanization makes steel last longer.
Be sure to choose the right galvanized steel for your project. There are two main methods of galvanization: items can be hot dip galvanized, and electro galvanized. Both methods rely upon a layer of zinc to protect the metal from the outside environment. Each method serves a purpose, but there are differences. These two methods vary in zinc application, aesthetics, and durability. Hot dipped galvanization is an excellent choice for buildings and structures. It creates a thick coating that stands the test of time outdoors. Electro galvanization creates a good-looking outer layer. This thinner coating works well for small, less vulnerable items. Let’s look:
HOT DIP GALVANIZED: This is the process of dunking steel into melted zinc. When it’s taken out, the zinc cools and forms a coating onto the steel. The coating from the hot dipped process is thick and creates a somewhat dull finish. Hot-dipped steel is tough, durable, and abrasion resistant. This layer of protection is ideal for large, exposed items. It will be virtually maintenance free, which will bring cost savings. Think: no repairs, maintenance, or replacements.
To break it down, hot dipped galvanized offers a thick protection from the elements. Its finish is dull yet durable, especially for large items. Electro galvanized offers a thin layer of protection that’s smooth, shiny. It is a good option for smaller, more intricate items, although it is less durable than hot dipped.
Either way, galvanized steel will last longer than steel that is not galvanized. In the storage industry, you have options for your steel containers. Powder coating and painting are ways to increase the longevity of storage containers. But if you’re looking to decrease your maintenance and repair costs with a product that will last, choose galvanized. As for storage containers, hot dipped galvanized will offer the most corrosion protection. You will add years to the investment you’ve made with a rust-free, maintenance-free storage solution.
