At the beginning of the New Year, 2024 is destined to be an extraordinary year. Major countries in the world, such as the United States, the United Kingdom, China and Australia, have directly suffered from extreme climate impacts such as extreme heat, snow, freezing rain and floods, causing great property and personnel losses.

The EU climate monitoring agency Copernicus Climate Change Service issued a press release on February 8 stating that January 2024 was the hottest January on record globally, with the global average surface temperature reaching 13.14 degrees Celsius, which was higher than the previous hottest month of 2022. January was 0.12 degrees Celsius warmer and 1.66 degrees Celsius warmer than the pre-industrial January average from 1850 to 1900. This is the eighth consecutive month since June 2023 that the monthly temperature record has been set. The communiqué further pointed out that the record-breaking high temperatures are mainly caused by the El Niño phenomenon and rising global ocean surface temperatures. The main factor leading to high ocean surface temperatures is the continued increase in greenhouse gas concentrations.

According to relevant reports and statistics from the National Weather Service and CBS, many places in the United States have been hit by violent winter blizzards since mid-January, with heavy snowfall occurring in many places such as New Jersey, Connecticut, and Massachusetts. In San Diego's National City, 10.795 centimeters of rain fell, significantly exceeding the area's average winter monthly rainfall of 5.08 centimeters. On January 21, heavy snow and freezing rain caused road closures and power outages for nearly 100,000 residents in New Jersey, USA.

Before and after the Chinese New Year holiday that just passed, from January 31 to February 5, large-scale persistent rain, snow and freezing weather occurred in central and eastern of our country. The cumulative snowfall in Henan, Shandong, Hubei and other places was extreme. Henan Freezing rain occurred in five provinces, Hubei, Anhui, Hunan and Guizhou. The rain in the south of the Yangtze River was not weak, accompanied by thunder and lightning. This rain and snow lasted the longest so far this winter and affected the widest range. This time, the widespread and persistent rain, snow and freezing weather in 10 provinces in China resulted in highway road closures, traffic jams, large-scale suspension of high-speed rail trains, and a large number of people who went home to celebrate the New Year and were trapped on the road unable to move. This really made people in the " Hundreds of millions of people traveling to and from the Spring Festival once again experienced the power of extremely severe weather. At the same time, many domestic infrastructures withstood extreme tests second only to the "2008 Snow Disaster."

Extreme climate freezing rain, blizzard, high temperature and other infrastructure, such as highway pavement guardrail, bridge, building structure, etc., have huge, hidden destructive power. The phenomenon of rain and even acid rain in extreme climates can lead to the corrosion and rust of building structures and buildings, and the accumulation of long-term subtle damage will greatly reduce its service life, resulting in a great increase in maintenance costs and replacement costs, and even lead to casualties.
Nanjing Sedray Industries Co., Ltd. actively play the enterprise consciousness, take the initiative to assume corporate responsibility, continue to innovate new materials, and develops a low-carbon FRP products series——Dragonbolt™ Composite Fasteners、Dragonbar™ FRP Reinforced System, 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) , Dragonpower™ Cable Management System .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:
1. Low VOCs content
Using new environmentally friendly materials, the content of volatile organic compounds is very low,
which is friendly to the environment and people;
2. Low thermal expansion coefficient
The thermal conductivity of FRP products is 0.487 W /(M.K), only 1/100 of metal, specially suitable for outdoor
construction, long-term high temperature will not cause skin burns;
3. Corrosion Resistance
FRP/GFRP products will never corrode, rust or lead to concrete spalling in the concrete structure;
4. 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;
5. Long Life Cycle
FRP/GFRP products are very durable, Service life of 50~100 years, therefore, can reduce later maintenance and
upgrade costs;
6. Light Weight and High Strength
The density of FRP reinforcement products is only 1/4 of that of metal materials. In modern times with high labor costs
and oil prices, labor costs and transportation costs can be greatly reduced. At the same time, the frp rock bolts has
strong thread load capacity, which can effectively substitute the use of metal rock bolts (slope support bolts);
7. 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.
