Recently, the futures have fallen, and domestic steel prices have continued to weaken, which has made the market mentality pessimistic. In terms of downstream demand, after half a year of hard work, the degree of improvement is still limited, but the production enthusiasm of steel mills is not diminished. In this situation, the future of the steel market is rampant.

From 79 to 35, 43 to 11, and 44 to 32, the reduction in a set of numbers has attracted a lot of attention in the field of foreign investment.

Hot-rolled sheets, that is, hot-rolled steel-rolled steel sheets or steel strips, commonly known as hot plates, are usually also written as stencils, such as hot-rolled sheets, but all refer to the same hot-rolled sheet. Refers to a steel plate having a width greater than or equal to 600 mm, a thickness of 0.35-200 mm, and a steel strip having a thickness of 1.2-25 mm. The cold rolled sheet is obtained by rolling a hot rolled coil as a raw material at a recrystallization temperature at room temperature.

Although the demand for spiral steel pipes has been shrinking in the process of slowing domestic economic growth, since the beginning of 2019, the four major mines have continued to increase production with the support of lower production costs, and the supply continues to increase. In the first quarter of 2019, the output of the four major mines increased significantly year-on-year. In the second quarter, except for FMG, the output of the other three major mines continued to grow year-on-year. According to the seasonal law, the annual high output will appear in the third quarter, and the medium-term ore supply is likely to maintain a growing trend.

Users who have purchased spiral steel pipes know that there is a certain gap between the prices of each spiral steel pipe manufacturer. Then, according to which factors are the prices of spiral steel pipes determined? The following are some of the factors summarized by the spiral steel pipe manufacturers, you can find out, I hope to help everyone:

　　The inner diameter of the stainless steel cylinder tube indicates the output force of the cylinder. The piston should slide smoothly in the cylinder, and the inner surface roughness of the cylinder should reach ra0.8um. The inner surface of the steel pipe column should be plated with hard chrome to reduce friction and wear and prevent corrosion. The cylinder material is made of high-strength aluminum alloy and brass, except for high-carbon steel pipes. This small cylinder is made of stainless steel. In corrosive environments, cylinders using magnetic switches or cylinders should be made of stainless steel, aluminum or brass.
