16 gauge Galvanized steel

In modern construction and industry, galvanized steel has become one of the indispensable materials due to its unique anti-corrosion properties and superior mechanical properties. Then as the leader in this large family, 16-gauge galvanized steel is widely used in various facilities with its unique specifications and excellent performance. It not only has the high strength and toughness of ordinary steel, but the zinc on its surface also enhances its corrosion resistance. This allows 16-gauge galvanized steel to maintain stable performance in humid, rainy, or corrosive environments, it is often used to make bridges, road guardrails, and house frames, as well as chemical equipment, power facilities, marine engineering, and other fields.

Then, I will delve into the definition, application, and performance characteristics of 16 GI steel.

What is 16 gauge Galvanized steel?

Generally speaking, it refers to galvanized steel sheets with a thickness of 1.61mm. Then galvanized steel sheet refers to a metal anti-corrosion method in which a layer of zinc is plated on the surface of steel because the zinc coating can effectively prevent the steel from being corroded or rusted by air, water, and other media.

16 gauge Galvanized steel Features

1. Corrosion resistance, as well as paintability.

2. Then, formability and spot weldability.

3. In addition, according to the zinc layer: the size of the zinc flowers and the thickness of the zinc layer can indicate the quality of galvanizing. For example,  the smaller and thicker the zinc flowers, the better.

4. Importantly, Wanzhi can also add anti-fingerprint treatments and others.

5. It can be distinguished by its coating, such as Z12, which means that the total amount of coating on both sides is 120g/mm.

6. Longer life: This is a common advantage of galvanized steel, due to it having a service life of up to decades.

7. Environmental protection: no harmful substances are produced during production and use, and the used 16-gauge galvanized steel can be recycled and reused.

Applications of 16 gauge galvanized steel

1. Construction field: Used as pipes for transporting fluids such as water and gas, as well as supports for building structures, for example: scaffolding, guardrails, handrails, etc.

2. Manufacturing industry: Secondly, the production of structural parts such as frames and suspension systems, and the manufacture of automobiles and motorcycles. Bed frames and chair frames.

3. Agriculture and animal husbandry: Later, farm fencing, frames, and brackets for livestock equipment and building greenhouse skeletons.

4. Municipal construction: drainage systems for urban roads, bridges, and tunnels, guardrails, and decorations for public facilities such as parks and squares.

5. Electric power and communications: Then, cable trays, telephone poles, and other components, support, and protection of communication towers, base stations, and other facilities.

6. In petrochemicals, water treatment: At last, it is used to transport various fluid media.

7. Other fields: Fitness equipment, sports equipment.

How heavy is 16 gauge GI steel?

Gauge	US Standard Gauge	Galvanized steel
	(inches)	Weight(lb/ft²)
17	0.0563	2.406
16	0.0625	2.656
15	0.0703	2.969

How thick is 16 gauge GI steel in mm?

As shown in FIG. Typically, tube gauges are expressed using a number followed by the letters “SWG,” which stands for “standard wire gauge.” For example, a tube with a 16 SWG thickness has a wall thickness of 0.065 inches (1.65 millimeters).

What does the 16 gauge of galvanized steel mean?

The word “gauge” in steel gauge refers to the thickness measurement of steel, Meanwhile, this measurement is critical in determining the strength and durability of steel.
Secondly, a gauge size is a number that indicates the thickness of a piece of metal plate, and interestingly, the higher the number, the thinner the plate. For example, each gauge size standard has a different equivalent thickness, and these standards are based on the weight of a plate of a given material.

History of Steel Gauge

The concept of steel gauge has been around for centuries. Simply put, it was based on the number of times steel was processed to a certain thickness, usually measured in numbers. For example, in the US, this ranges from about 3 to 30. Interestingly, as mentioned above, the metal gauge number is inversely proportional to the thickness of the steel, i.e. the lower the gauge number, the thicker the steel. This metric might seem a bit counter-intuitive, but it’s a standard that has been used in the industry for many years.

Gauges in the US and the UK

The Brown and Sharpe Gage, also known as the American Wire Gage (AWG), is used for most nonferrous metals, such as Aluminum and Brass. For instance, in the UK, the Birmingham Gage (BG) is used for a variety of metals and should not be confused with the Birmingham Wire Gage (BWG), which is used for wires.

Relationship between gauge and thickness

Lastly, a standard exists for Zinc in which a higher gauge number indicates a thicker sheet. In detail, the chart below can be used to determine the equivalent sheet thickness, in inches or millimeters, for a gauge number from the selected gauge size standard. The weight per unit area of the sheet can also be seen in pounds per square foot and kilograms per square meter.

Galvanized Steel Gauge Numbers

Emphatically, in terms of steel specifications, the numbers are inversely proportional to the thickness of the steel. For example, 10-gauge steel is thicker than 12-gauge steel. So, let’s take a look at some common steel specification numbers and their corresponding thicknesses:

FAQ

1. What are your prices?

Now that, our prices are subject to change depending on supply and other market factors.

We will send you an updated price list after your company contacts us for further information.

2. Why do lower gauge numbers signify thicker Galvanized steel?

The gauge system dates back to the times when steel sheets were created by hammering them to the desired thickness. The number of hammering cycles determined the galvanized steel sheet and gauge number—fewer cycles resulted in thicker sheets, hence lower gauge numbers signify thicker steel.

3. Can you supply the relevant documentation?
