A Simple Guide To Galvanized Steel Angle

Galvanized steel angles are one of the most common structural steel shapes to use in any construction project. It is strong, durable, affordable, and easy to be sued in many different ways. For buying GI steel angles, here are something you need to know:

What Is Galvanized Steel Angle?

Galvanised angle, sometimes called angle iron, is named for its shape. It is a long strip of steel with two sides perpendicular to each other and angled at 90°. Generally, they are available both as “equal angles” where both legs are the same size and “unequal angles” where the legs are the different sizes.

How Is This Material Produced?

The steel angle can be either hot dipped galvanized or cold galvanized so as to achieve the purpose of corrosion and rust prevention. For example:

Hot Dipped Galvanizing: the process of hot-dip galvanizing is to dip the rust-removed angle steel in the molten zinc solution at about 500°C. The zinc layer will be firmly attached to the surface of the steel, substantially increasing the corrosion resistance. It is suitable for various higher corrosive environments such as strong acid and alkali mist. Hot-dip galvanizing provides a distinct advantage over other corrosion protection methods, making HDG steel angles commonly manufactured and purchased in the market.

Cold Galvanizing: this type is to accomplish its anti-corrosion through electrochemical principles. Before galvanizing, the steel must be mechanically deducted (sandblasting, shot blasting), and then its surface is free of oil, rust, scale, and other contaminants, or leaves only slight traces. This can ensure the full contact between zinc powder and steel, achieving the ideal state of cold galvanizing. Cold galvanized steel angle generally needs to be processed according to customers’ needs.

What Benefits It has?

Here are some benefits that GI angle iron can offer your project:

- Affordable

The cost of hot-dip galvanizing for corrosion protection is lower and can be a cost-effective replacement for many higher-priced metals, such as aluminum, stainless steel.

- Durable

The angle steel has the characteristics of uniform zinc layer, strong zinc adhesion, and strong corrosion-resistance, making it durable to use. Besides, without having to repair, you can enjoy GI steel angles with a lifetime of more than 20 years in urban or offshore areas and 35 years in suburban areas.

- Light

Compared with wood or concrete of similar strength, a GI steel angle is much lighter and compact. This makes it a perfect product to use wherever weight and strength are a concern.

- Anti-corrosive

Zinc is a strong material to resist corrosion and prolong lifespan. The combination of zinc and steel makes the angle iron highly resistant.

- Saving time and energy

The galvanizing process is much faster than other coating methods. Besides, it is easy to work with, greatly shortening your construction period.

Applications It Can Be Used in

It is a versatile product that can be used in many projects, from creating the frame for a lawnmower to adding bracing to a heavy-duty trailer. It can also act as a structural component on a lightweight roof or be used for purely decorative purposes, such as art projects. Here are some examples of it:

Powder tower,

Building steel structural components,

Bridges, 

Machinery,

Railways, 

Truck trailers or beds, 

Racks, etc.
