The price rise of several raw materials affects the cost of glass greenhouse

In recent years, the price of raw materials for glass greenhouses has fluctuated significantly. The first wave: epidemic situation, the second wave: sharp rise of materials, the third wave: staggering power consumption, 2 days off for 5 days, the fourth wave: suppliers' price increase, shutdown and shutdown, and the last wave, the delivery period will be longer and longer, and the price will rise higher and higher. What are the main factors affecting the price of the highest corrugated glass greenhouses in our greenhouses, About the floating range, Guangyuan greenhouse will share with you.

Brief introduction of corrugated glass greenhouse

Glass greenhouse, commonly known as the transparent building built of glass, is equipped with an environmental control system. Its main structure is composed of hot-dip galvanized light steel skeleton and glass covered with aluminum profile. Because of its firm building structure, strong wind and snow resistance and super service life, it is the greenhouse structure most used in developed modern facility agriculture.

Four main materials affecting the cost of glass greenhouse

steel products

As the main steel structure framework of the glass greenhouse is made of hot-dip galvanized steel pipe, steel is the first influencing factor. The steel content of glass greenhouse is about 15 ~ 25kg per square meter. Considering the accessories of the steel framework of the greenhouse and other factors, the increase of 1000 yuan per ton of steel is about 5 ~ 10 yuan per square meter.

Aluminum

Aluminum is the profile used to fix the glass. Both the top and surrounding glass, as well as the top opening window and valgus window are made of aluminum. The main reason is that aluminum has good ductility, no rust and long service life. At present, the price of aluminum rod is 23000 ~ 24000 yuan / ton. Compared with last year, it increased by about 5000 ~ 6000 yuan / ton.

Glass

Glass is the top and surrounding material of glass greenhouse, which is the most direct to the cost of greenhouse. The price of 4mm tempered scattering glass at the top is about 50 ~ 60 square meters at present, and about 40 ~ 50 square meters last year.

Price trend of greenhouse raw materials during the year

Due to the insufficient supply of coal energy and the impact of environmental protection during the year, the price of greenhouse materials will continue to rise during the year, and there is basically no room for decline.
