Under the influence of various factors such as the intensification of the conflict between Russia and Ukraine, the escalation of sanctions against Russia by the European Union and the United States, and the harsh climate, the worldwide energy crisis has further intensified. The fiberglass rebar and fiberglass building products produced by our company can effectively alleviate this trend.

In the 21st century, water resource has gradually become a strategic resource, which plays a vital role in the survival and development of human beings. The scarcity of water resources forces human beings to take various measures to ensure the sustainable development of water resources.

By 2025, extreme climate events will further ravage the Earth. Extreme heat zones will expand, Greenland's 3 million-year-old ice will melt, and China's high-temperature and rain belts will shift northward. Wildfires, droughts and floods will continue, and food production will decline. These disasters, compounded by the "heat dome" phenomenon, will unfold, further necessitating urgent ac...

From China's Tiangong space station, Chinese astronauts can't help but admire the earth as a "beautiful, blue ball of water". However, human beings on the earth have to face an embarrassing reality: according to the United Nations research report, the world's fresh water resources only account for 2.5 percent of its total water, of which more than 70 percent are frozen in the Antarctic and Arctic ice caps, plus difficult to use mountain glaciers and permafrost snow, 86 percent of the fresh water resources are difficult to use. At present, the freshwater resources that can be directly used by human beings are mainly in rivers, lakes and groundwater, accounting for only 0.26% of the earth's total water volume. Data show that more than 1 billion people currently live in areas of water scarcity, and as many as 3.5 billion people will face water scarcity by 2025.
In the 21st century, with the rapid development of industry and agriculture, water resource is rapidly becoming a precious and scarce strategic resource. The sustainable utilization of water resource is not only a resource problem, but also a major strategic problem related to the sustainable development and long-term stability of national economy and society. While the water shortage is becoming more and more prominent, people are polluting the water on a large scale, leading to the deterioration of water quality. Water pollution is mainly caused by waste water, gas and residue from all human manufacturing. According to the United Nations, about 40% of the steady flow of rivers around the world is polluted. "The consequences of the water crisis are clear, in the form of food insecurity, conflict and migration, and financial instability, with huge risks to human lives and livelihoods if no action is taken," said Andrew Steele, president and CEO of the World Resources Institute.
The report by the Washington-based World Water Institute found that the three most immediate solutions to the water crisis were to improve agricultural efficiency, invest in water infrastructure and use water sustainably. Among them, strengthening the sustainable recycling of water resources is the most widely used method in the rapid development of cities and industrial zones, including sewage treatment and seawater desalination. Sewage treatment is mainly the polluted water of people's production and life through sewage treatment facilities, so that the sewage meets the water quality requirements of discharge into a body of water or reuse of its purification process. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical, catering and other fields. Desalination is an effective way to develop and increase water resources by removing salt from seawater and providing fresh water for industrial production and residential life. In both the process of water treatment, are faced with production workshop and facilities by the heavy metal in waste water or sea water corrosion, salt and other contaminants, especially the concrete construction (steel), metal fence, pipe supports, electrification facilities (such as bridge, power distribution cabinet), the loss caused by the run into the billions of dollars every year.
Nanjing Sedray Industries Co., Ltd. developed FRP/GFRP products -- Dragonbar™ fiberglass rebar& form tie, Dragonpro™ fiberglass building products ( including：(1) standard structural profiles, (2) FRP handrail systems, (3) FRP decks & floors, (4) FRP gratings and accessories ), Dragonstrut™ fiberglass framing system (fiberglass support system) ( including：(1) FRP Strut Channels, (2)FRP Channel Fittings, (3)Fiberglass Threaded Rods，(4)FRP Hex Flange Nuts，(5)FRP Channel Washers, (6)FRP Molded Hex Flange Bolts，(7)FRP Assembled Hex Flange Bolts，(8)FRP Hex Nuts，(9)FRP Threaded Rod Couplers，(10)FRP Standard Channel Nuts，(11)FRP Molded Beam Clamps，(12)FRP Fabricated Beam Clamps, (13)FRP Fabricated Clevis Hangers), can better reduce this unnecessary loss. These products mainly use high performance reinforced glass fiber and corrosion resistant resin and necessary additives, through the pultrusion process and special processing technology to produce, compared with traditional materials (steel, aluminum, stainless steel, plastic), has a very obvious advantage:
Corrosion Resistance: FRP/GFRP products will never corrode, rust or lead to concrete spalling in the concrete structure;
High Chemical Resistance: wastewater treatment, water treatment and desalination plants exposed to chemicals, water or high salt content of the environment, FRP/GFRP products can be very good resistance to the corrosion of the harsh environment;
Long Life Cycle: FRP/GFRP products are very durable, therefore, can reduce later maintenance and upgrade costs;
High Bending Modulus: the bending modulus of FRP/GFRP products is higher than that of thermoplastics, which is the ideal characteristic of the key components used for wastewater aeration. It can move in the water treatment process with a relatively low bending degree in response to any high bending load requirements in the water;
Low Moisture Absorption: unlike many plastics, the moisture absorption of FRP products is very low, even if it is soaked in water for a long time, there will be no obvious size change or mechanical property loss.
