How much is a galvanized square tube a ton of galvanized square tube price trend today

What is a galvanized square tube? Galvanized square tube Galvanized square tube is a hollow square with a square cross-sectional shape and size made by hot-rolled or cold-rolled galvanized steel strip or galvanized coil as a blank, formed by cold bending and then high-frequency welding Cross-section steel pipe; or galvanized rectangular Rectangular Pipe made of cold-formed hollow steel pipe prepared in advance by hot dip galvanizing. So, do you know the price of galvanized square tube? How much is a galvanized square tube for one ton ? I believe that for the first time friends who are in contact with galvanized square tubes, there will be such questions. Don't worry, if you have needs in this regard, you may wish to come with me to understand the relevant knowledge of how much a ton of galvanized square tube is ! Maybe it can make you have unexpected gains!

Galvanized square tube classification

Galvanized square tubes are divided into hot-galvanized square tubes and cold-galvanized square tubes from the production process. It is precisely because of the different addition of these two kinds of galvanized square tubes that they have created many different physical and chemical properties. In general, they have many differences in strength, toughness and mechanical properties.

1. Hot Dip Galvanized Square Tube

Hot-Dip Galvanized square tube: It is a square tube made of steel plate or steel strip after crimping and welding, and on the basis of this square tube, the square tube is placed in a hot-dip galvanized pool after a series of chemical reactions A square tube formed. The production process of the hot dip galvanized square tube is relatively simple, and the production efficiency is very high, and there are many varieties and specifications. This square tube requires few equipment and capital, and is suitable for the production of small galvanized square tube manufacturers. But in terms of strength, the strength of this steel pipe is far lower than that of seamless square pipes.

2. Cold galvanized square tube

The cold-galvanized square tube uses the principle of cold-galvanized on the square tube to make the square tube have anti-corrosion performance. Different from hot-dip galvanizing, cold-dip galvanizing coatings are mainly anti-corrosive by electrochemical principle. Therefore, it is necessary to ensure sufficient contact between zinc powder and steel, resulting in electrode potential difference, so steel surface treatment is very important.

3. The difference between hot and cold galvanizing

There are two types of galvanized square tubes: hot-dip galvanized square tubes and electro-galvanized square tubes. Hot-dip galvanized square tubes include wet method, dry method, lead-zinc method, and redox method. The main difference between the different hot-dip galvanizing methods is to use a method to activate the surface of the pipe body to improve the quality of galvanizing after acid pickling and cleaning of the steel pipe. At present, the dry method and the redox method are mainly used in production, and the characteristics are shown in the table. The surface of the zinc layer of electro-galvanized zinc is very smooth and dense, with a uniform structure; it has good mechanical properties and corrosion resistance; the zinc consumption is 60% to 75% lower than that of hot-dip galvanizing. Electrogalvanizing has certain technical complexity, but this method must be used for single-sided coatings, double-sided coatings with different thicknesses on the inner and outer surface coatings, and galvanizing of thin-walled tubes.

Specification of galvanized square tube

The specifications of hot dip galvanized square tube are: 30 * 30 * 2.0, 40 * 40 * 3.0, 50 * 50 * 2.5, 60 * 60 * 50, 80 * 80 * 4.0, 100 * 100 * 3.0, 120 * 120 * 6.0 , 80 * 80 * 6, 30 * 30 * 3.0, 40 * 40 * 4.0, 200 * 200 * 8, 250 * 250 * 10, 300 * 300 * 12, 400 * 400 * 12;

The specifications of the cold-galvanized square tube are: 20 * 20 * 2, 40 * 40 * 2.0, 50 * 50 * 3.0, 80 * 80 * 3.0, 150 * 150 * 6.0, 140 * 140 * 4.5, 160 * 160 * 6.0 .

Galvanized square tube use

Since the galvanized square tube is galvanized on the square tube, the application range of the galvanized square tube has been greatly expanded compared with the square tube. It is mainly used in curtain walls, construction, machinery manufacturing, steel construction projects, shipbuilding, solar power support, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, etc.

Characteristics of galvanized square tube

Galvanization has stronger protection and corrosion resistance. The entire structure is made of zinc, forming a dense quaternary crystal, which forms a barrier on the steel plate, thus effectively preventing the penetration of corrosion factors. The corrosion resistance comes from the protective function of the zinc barrier layer. When zinc is used for sacrificial protection on the trimmed edges, scratches and scratches of the coating, zinc forms an insoluble oxide layer, which acts as a barrier protection.

Calculation of galvanized square tube

Calculation of theoretical weight per meter of galvanized square tube

4 * (side length-thickness) * 0.00785 * 1.06 * thickness

Among them, the side length and the wall thickness are in millimeters, and the value is directly substituted into the above formula, and the weight of the square tube per meter is obtained in kilograms.

For example, a square tube of 30 x 30 x 2.5 mm, the weight per meter can be calculated according to the above formula: 4 x 2.5 x (30-2.5) x 7.85 = 275 x 7.85 = 2158.75 grams, which is about 2.16 kilograms.

When the wall thickness and side length are in millimeters, 4 x wall thickness x (side length-wall thickness) calculates the volume of the square tube per meter length, in cubic centimeters, and then multiplies the specific gravity of iron per cubic 7.85 grams per cent, which is the weight in kilograms per square meter of tube.

Galvanized square tube price list
