7 new houses added to the Chicago listings

The Chicago Fire Department has recently updated its listings on the site, thanks to a generous contribution of image files from Hank Sajovic, who provided photos of rigs and stations. Additionally, several fire stations now feature custom patches, which are proudly displayed here with permission from Jack Connors. Here are some of the newly added stations: - Engine 18 (1st District) - Engine 84 (5th District) - Engine 62, 75, 80, 93, 97 (6th District) You can view the new house for Engine 18 below, featuring its unique patch: Here’s the new station for Engine 84: Below is an image of Engine 62’s new house: Here’s the patch from Engine 75’s station: And finally, here’s a look at Engine 97’s new house:

Galvanized Steel

Galvanized steel is a type of steel that has been coated with a layer of zinc through a process called galvanization. This coating helps protect the steel from rust and corrosion, making it a popular choice for many industrial and construction applications.

The process of galvanization involves immersing the steel in a bath of molten zinc, which reacts with the iron in the steel to form a protective layer of zinc-iron alloy. This layer is tightly bonded to the steel surface, providing excellent corrosion resistance.

There are two main types of galvanization processes: hot-dip galvanizing and electro-galvanizing. In hot-dip galvanizing, the steel is immersed in a bath of molten zinc at temperatures above 800°F (427°C). This process creates a thick, durable zinc coating that provides long-lasting protection against corrosion.

Electro-galvanizing, on the other hand, involves using an electric current to attach a thin layer of zinc to the steel surface. While this process creates a thinner zinc coating compared to hot-dip galvanizing, it is often used for applications that require a more cosmetic finish or where intricate shapes need to be coated.

Galvanized steel is commonly used in a wide range of applications, including construction, automotive manufacturing, and industrial equipment. It is known for its durability, strength, and resistance to corrosion, making it an ideal choice for outdoor structures, such as fencing, roofing, and guardrails.

One of the key benefits of galvanized steel is its low maintenance requirements. Because the zinc coating provides a barrier between the steel and the environment, galvanized steel is less prone to rust and corrosion compared to untreated steel. This makes it a cost-effective and long-lasting material for a variety of applications.

In addition to its corrosion resistance, galvanized steel also has excellent mechanical properties, including high tensile strength and impact resistance. This makes it a reliable and sturdy material for structural components in buildings, bridges, and other infrastructure projects.

Despite its many advantages, galvanized steel does have some limitations. For example, prolonged exposure to acidic or alkaline environments can weaken the zinc coating and reduce its effectiveness in protecting the steel underneath. In such cases, additional protective measures may be necessary to prevent corrosion.

Overall, galvanized steel is a versatile and durable material that offers many benefits for a variety of applications. Whether used in construction, automotive, or industrial settings, galvanized steel provides the strength, corrosion resistance, and long-lasting performance that is essential for demanding environments.
