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. 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.

Next, we will delve into the definition, application, and performance characteristics of 16-gauge galvanized steel to appreciate its unique charm!

What is 16 gauge Galvanized steel?

It usually refers to a galvanized steel sheet with a thickness of 1.61mm. Galvanized steel is a metal anti-corrosion method that covers the surface of the steel with a layer of zinc. 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, paintability.

2. Formability and spot weldability.

3. Divided by zinc: the size of the spangle and the thickness of the zinc layer can indicate the quality of the galvanizing, the smaller and thicker the better.

4. 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, with 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 water, gas, and other fluid transportation pipelines, building structure support, such as scaffolding, protective railings, and handrails.

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

3. Agriculture and animal husbandry: farm fences, 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: cable trays, telephone poles, and other components, support, and protection of communication towers, base stations, and other facilities.

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

7. Other fields: fitness equipment, sports equipment.

How heavy is 16 gauge GI steel?

How thick is 16 gauge GI steel in mm?

As shown in FIG. Tube gauges are typically 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 term “gauge” in steel gauge refers to the measurement of the steel’s thickness, a measure which is vital in determining its strength and durability. Gauge (or gauge) sizes are numbers that indicate the thickness of a piece of sheet metal, with a higher number referring to a thinner sheet. The equivalent thicknesses differ for each gauge size standard, which was developed based on the weight of the sheet for a given material.

History of Steel Gauge

The concept of steel gauge has been around for centuries, originating from the number of times steel had to be processed to reach a certain thickness.

Steel gauge is typically measured in numbers, ranging from about 3 to 30 in the United States. Interestingly, the metal gauge number is inversely proportional to the steel’s thickness – 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. 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. 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.

What is the yield strength of 16 gauge GI steel?

Its allowable loads are based on 54mil (16ga) U-Channel bridging with minimum yield strength, Fy=33 ksi, and tensile strength, Fu=45 ksi.

Galvanized Steel Gauge Numbers

Remember, in the context of steel gauge, a lower number denotes thicker steel, and a higher number indicates a thinner sheet of steel. Let’s take a look at some common steel gauge numbers and their corresponding thicknesses:

steel gauge and thicknesses

gauge and thickness

The gauge is a standardized measurement of the thickness of steel sheets and is inversely proportional to the thickness of the steel. The lower the gauge number, the thicker the steel.

For example, 10-gauge steel is thicker than 12-gauge steel.

FAQ

1. What are your prices?

Our prices are subject to change depending on supply and other market factors.

We will send you an updated price list after your company contact 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?

Yes, we can provide most documentation including Certificates of Analysis / Conformance;    Insurance;    Origin, and other export documents where required.

4. What is the average lead time?

For samples, the lead time is about 7 days.

For mass production, the lead time is 5-20 days after receiving the deposit payment.    The lead times become effective when :

(1) we have received your deposit.

(2) we have your final approval for your products.

If our lead times do not work with your deadline, please go over your requirements with your sale.

In all cases, we will try to accommodate your needs.

In most cases, we are able to do so.
