Greenhouse steel pipe is mainly made of greenhouse composite materials made of pull rod, pressure rod, column, and arch rod to cover the plastic film in a greenhouse. This shape is an arch round plastic greenhouse, this greenhouse covers a large area, the effect of heat absorption is also very good, easy to build, and the cost of building one is also very low. The raw material sources of greenhouse steel pipes are very rich and extensive, and the application effect is good.
The lighting surface of each type of shed is designed as an arc, improving the Angle of the light surface, because the lighting surface is curved, no dust accumulation, good light transmission, and high temperature in the shed. After measurement, the average temperature in the shed is 3℃ higher than that of the traditional bamboo pole cement column shed, the yield is increased by 15~20%, and the harvest date is advanced. Scientific formula, surface no moisture absorption, no return halogen through modification technology and scientific production process, to solve the greenhouse frame rod easy moisture return halogen, poor water resistance and variable type of the shortcomings, so that the greenhouse steel pipe in the high temperature and high humidity environment, there is little drip, frost phenomenon, and reduce pests and diseases.
At present, the inventory situation is still ok, and there is no hurry to take the initiative, while the current existing resources of greenhouse steel pipes are mostly in a state of loss. Therefore, in the short term, the market price is more limited. It is expected that the price of billet in the domestic market will rise slightly next week, and scrap steel and coal coke will be mainly stable. It is expected that domestic demand in the steel industry will hardly improve. Upstream iron ore prices are strong, greenhouse steel demand is weakening, as far as the current situation is concerned, the steel industry overcapacity is still serious, the next few years, environmental protection will become the norm.
In this case, the risk of steel mill collapse will rise further. In order to improve the corrosion resistance of the steel pipe, the general steel pipe is galvanized. Galvanized steel pipe is divided into hot dip galvanized and electric galvanized two, hot dip galvanized galvanized layer is thick, electric galvanized low cost, the surface is not very smooth. Used as steel blowing oxygen pipe, generally with small diameter welded steel pipe, specifications from 3/8-2 inches of eight. Made of 08, 10, 15, 20 or 195-Q235 steel strip, in order to prevent corrosion, some should be aluminized.
