Long-lasting steel is a key material for those of us in the storage industry. We all know that steel has proven itself a valuable material. Storage needs to be strong, secure, and safe from the elements. And facilities are looking for a long-lasting product. Storage owners and operators have choices in the steel used to make their relocatable and portable storage units. Galvanized steel, for example, is an excellent choice for facilities looking to decrease maintenance and repair costs. This durable material makes storage units rust-free, maintenance free, and long lasting.
What is galvanized steel? And what makes this a long-lasting steel? In today’s world, galvanized objects are all around us. Take a look at staircases, stop signs, ladders, nails, bridges, benches, buckets, pipes, car parts, buildings, structures, and storage containers. All probably galvanized. And with good reason. The iron in steel is prone to oxidization. Without a layer of protection, or galvanization, steel will rust.
Galvanization 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. It helps prevent rust and wear. Some objects and structures made with galvanized steel may not need maintenance for 40-50 years! That is certainly a long-lasting steel. This is not the case with bare or untreated steel. 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 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.
ELECTRO GALVANIZED: Here, the process is putting the steel into a cold solution of zinc salts and exposing it to an electrical current. The zinc attaches to the steel to create a layer of protection. This method of galvanization brings an aesthetically pleasing surface that is smooth, bright, and shiny. The zinc coating from electro galvanization is thin, which is great for smaller items. Electro galvanized products do not have a long lifespan or optimal durability. But they look beautiful, which is a benefit.
