Galvanized Square Steel Tube

Galvanized square steel tube is a tough and durable material. It is designed with a square hollow section, which is with multiple-axis loading and uniform strength for different industries. Wanzhi Steel offers galvanized square tubing in many different sizes and wall thicknesses. More than that, it is easily welded, punched, or processed for different uses. It is lightweight but is able to withstand extreme temperatures and pressures. After being galvanized, it is also more corrosion resistant. Contact us for more details!

What Is Galvanized Square Tube?

Galvanized square pipe has a hollow square cross-section shape. It is made of a hot-rolled or cold rolled galvanized steel strip or galvanized coil as a billet by cold bending process and then by high-frequency welding.

Weight Calculation Formula

Below is the weight calculation formula of galvanized square tube for your reference.

4 * Thickness * (side length – thickness) * 7.85

Note: When the side length and wall thickness are in millimeters (mm), the value is directly substituted into the above formula, and the result is the weight per meter of the square tube. The weight per meter of a 30 x 30 x 2.5 mm square tube, for example, can be calculated according to the above formula as: 4 x 2.5 x (30-2.5) x 7.85=275 x 7.85=2158.75 grams, about 2.16 kg.

Galvanized Square Steel Pipe Uses

Generally, galvanized round tubing is mainly used in fluid transportation systems. While GI square tubes are mainly used as structural materials. It can be found as the support frame for curtain wall, solar power generation bracket, power tower, greenhouse, gate, fencing, etc. Except for construction uses, it is also widely used in machinery building, shipbuilding, agricultural and chemical machinery, automotive chassis, etc.

Type of GI Square Pipe

The zinc layer makes the square pipe more resistant to corrosion. There are two commonly used types of galvanized square pipe according to different production processes, including hot-dip galvanized square pipe and cold galvanized square pipe. The hot-dipped galvanized square pipe is mainly used type in recent years due to its great corrosion resistance. We mainly adopt hot-dipped galvanizing method.

Hot-dip galvanized square tube is a square tube made by welding steel plate or steel strip after crimping. On this basis, the square pipe is placed in the hot-dip galvanizing bath and then formed after a series of chemical reactions. While the amount of cold galvanization is only 10-50g/㎡, which has poor corrosion-resistance performance and is not suitable for extreme environments. Hot-dip galvanized square tube is superior to the cold galvanized square tube in appearance, strength, and mechanical behavior.

Benefits of Galvanized Square Tubing

1. Better Anti-corrosion Performance

The zinc element is more active than the steel element. The standard hot-dip galvanized anti-rust thickness can be maintained for more than 50 years without repair; in urban or offshore areas, the standard hot-dip galvanizing anti-rust thickness can be maintained for about 20 years without maintenance.

2. Low Maintenance

The GI square pipe is incredibly durable and the cost of rust prevention is lower than coating.

3. Strong Toughness

The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use and withstand more pressure.

4. Comprehensive Protection

Every part of the pipe can be plated with zinc, even in the recesses, sharp corners and hidden places can be fully protected.

5. Good Reliability

The galvanized tubes are metallurgically combined, and the zinc layer is not easy to fall off.

Quality of Galvanized Square Tube

Below are the methods to identify the good and bad quality of galvanized square pipes for your reference.

1. Color and Luster

One of the ways to identify a galvanized square tube is to observe its color and luster. A galvanized square tube with a smooth and bright color is better. This can be observed by the naked eye. When you choose one, you can pay attention to its color and luster.

2. Zinc Layer Thickness

Generally speaking, the thicker the zinc layer the better the quality of the galvanized square pipe will be. This is because the zinc layer provides good anti-corrosion properties for the pipe. Especially for long-term exposure to the outdoor environment, the thicker the zinc layer of galvanized square pipe the less likely it is to rust.

3. Appearance

The quality of the tube can be easily seen from its appearance. If the galvanized layer on the surface of the square tube is uneven and uneven on a large scale, it can be judged as a substandard product. In addition, if there are pockmarks and white spots on the surface of the galvanized square tube, this also indicates that it is of inferior quality.
