CHS pipe sizes follow specific standards and codes. For instance, in the United Kingdom, the British Standard (BS) 4360 outlines the preferred dimensions and tolerances for CHS. In the United States, the American Society for Testing and Materials (ASTM) provides specifications that are widely adopted, such as ASTM A500 for cold-formed steel structural tubing. Familiarity with these standards ensures that engineers and contractors select pipes that comply with local regulations and industry norms.

Wet air in rain and snow climate, steel mesh sheet exposed, easy to rust, to avoid affecting the use of steel mesh, it is necessary to carry out simple rust prevention treatment, of course, slight rust float will not affect the use of steel mesh. Common network site storage, rainy days, heavy snow, rainy days and rainy days, how to better save the steel mesh, this is a lot of friends need to consider.
- The management system of the rinsing water after the steel wire pickling should be regularly and regularly discharged after the rinsing water, and the rinsing water should be kept clean and low acid value as far as possible. The pH control is more appropriate. The concentration of plating aid should not be too high. Hot plating wire must be added ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled in the range of 50~80g/L. The addition of ammonium chloride or zinc chloride raw materials without the results of laboratory analysis shall be subject to criticism and education, and economic treatment if necessary.

- It was designed not only to be easy to install, but also to allow for quick and easy installation in harsh terrain such as cliffs, with little anchorage and little excavation. Based on the characteristics of heavy hexagonal mesh duplex structure, it can withstand the impact of falling rocks even when the steel wire is damaged.
- Generally, galvanized wire used for welding is required to have a certain hardness. After acceptance of galvanized wire, the first thing to do is to feel the hand, and the other thing is to test on the machine. Because the average user does not have testing equipment, it is also very inconvenient to test on the machine. Use a micrometer to measure the diameter of galvanized wire evenly, and keep it about 0.02mm above and below the contract signing standard, with neat appearance, no leakage plating and no mess.
- The last is the size of the barbed rope or blade barbed rope. The commonly used size is good, especially for some special-shaped products, which need to be mentioned repeatedly in the production process of the barbed rope factory to avoid unnecessary losses.
- Due to the implementation of the grassland contract operation obligation system, herdsmen have a high capacity to strengthen and raise their stainless steel barbed rope fence net in grassland pastoral areas, forming the phenomenon of high density and high height of stainless steel barbed rope fence net in grassland pastoral areas, which is destructive and even destructive to the survival of wild animals.
- Canary cage is also known as hibiscus cage, jade bird cage. Can be made of nickel-plated alloy or bamboo, for the refined round, square or rectangular (breeding cage) bird cage. The top of the cage has two kinds of flat top and dome, and the bottom of the cage is closed with a bottom circle. The circular cage is about 33 cm high and 20 cm in diameter; The square cage is 24.7 cm long, 24.7 cm wide and 33.8 cm high. The spacing of the cage is 1 cm, and the diameter is 0.2 cm. Cage bottom NEED NOT BAMBOO, MAKE IT WITH PLASTIC BOARD, bottom plate CAN move, FACILITATE PULL OUT WASH. Two perches are placed in the cage, and a food and drinking pot is placed in the cage. The cage has a board at the top of the cage to change the bird’s habit of looking up at the sky.

Large roll galvanized wire is processed by low carbon steel wire rod, through drawing molding, pickling rust removal, high temperature annealing, cooling and other processes. Large roll galvanized wire electroplating temperature should be controlled in 30-50℃. Because of the strong corrosivity of chloride ions in bath, quartz glass heater is generally used. Continuous production does not need heating, but need cooling cooling.
- The last is the size of the barbed rope or blade barbed rope. The commonly used size is good, especially for some special-shaped products, which need to be mentioned repeatedly in the production process of the barbed rope factory to avoid unnecessary losses.
- 3. The transport, storage and use of the binder of galvanized wire mesh should adopt safety and fire prevention methods according to the relevant regulations, so as to be safer.
- So, do you know how to choose the right dog cage? Choose a dog cage to focus on quality and practicality! Let’s take a look:

There are still some differences between the welding mesh and the wire mesh and the steel mesh. This mesh is mainly a welding mesh made of high quality low carbon steel wire straightened and cut, and then welded with electric welding equipment. It can be said that because of the characteristics of fast production and convenient transportation, it has been applied to many industries. The application of welding mesh in the industry, because the mesh has strong corrosion resistance and uniform mesh. It has become a special grid for floor heating in the building industry and has been applied in many fields.
-
The wire mesh is composed of low carbon steel wire or medium carbon steel wire, high carbon steel wire or stainless steel wire. There are two kinds of manufacturing technology of steel wire mesh, one is the weaving method, the other is the welding connection, the formation of grid.

Each coil of steel wire shall consist of one wire. The surface of the rod shall not have cracks, folds, scars, ears, layers or inclusions. However, indentation, pits, bumps, scratches and pockmarks are allowed, and the depth or height shall not be 0.2mm. There should be no corrosion and oxidation skin on the surface of the steel wire, and oxidation color is allowed by heat treatment. The surface of the wire is allowed to have scratches not exceeding half of the allowable deviation range of the diameter, and local defects not exceeding the allowable deviation of the appropriate diameter.
-
Galvanized barbed wire (barbed wire) is made of galvanized barbed wire twisted on the main wire, so as to play a protective and isolation role. Among them twist weave way is divided into single twist weave and double twist weave. Construction methods include direct installation and spiral insertion.

The whole welding process of galvanized steel wire mesh does not need special technological methods, good weldability. However, in a few cases, the welding process will present difficulties: the converter steel produced by the old smelting method has high nitrogen content and high impurity content, resulting in high cold brittleness, added aging sensitivity, lower quality of welded joints, and poor weldability.
-
Customers in the order of wire mesh will often shop around, most customers are in comparison with manufacturers to give the product price, the company tells you, do not blindly compare the price. To standards, production technology, manufacturers and other factors lead to different prices.
