In the first seven months of this year, the cumulative total imports of steel products from the United States and the cumulative imports of finished steel products were 26.876 million net tons (about 24.297 million tons) and 21.116 million net tons (about 19.196 million tons), respectively, compared to the same period in 2005. The corresponding indicators rose by 38% and 39% respectively. According to the cumulative import volume of steel products in the first seven months of 2006, it is estimated that the cumulative total import volume of steel products in the United States and the cumulative import volume of finished steel products will reach an all-time high record (45.9 million net tons and 36.3 million, respectively). Net tonnage is approximately 41.65 million tons and 32.9 million tons) - 49% and 52% higher than 2005 respectively.
Compared with the previous month, in July, the key products increased significantly in U.S. imported steel products include line pipe (up 55%), hot-rolled coil (up 51%), light bar (up 42%), and semi-finished steel. (Most used for converters and processing lines, up 41%), petroleum areas (oil pipes, up 34%) and several corrosion-resistant steels, including galvanized steel strips, various other metal coated strips and heat Dipping galvanized strips (84%, 19%, and 11%, respectively).
The American Iron and Steel Institute pointed out that in July, China has become the largest single exporter (region) of steel products sold to the United States. Under unusual market conditions, exports of steel products from mainland China to the United States this year will likely Increased to more than 4.5 million tons.
Ground Screw For Solar Power System
Ground Screw for solar power system is applied in fixation of solar panel. Pole anchor and Earth Anchor are fit for outdoor as the spiral pile mounting system adopts special materials that can resist corrosion, like HDG (hot dip galvanizing) and anodized silver15μm, screw pole mount system is adaptable for different soils. Additionally, it is easy to install. After it is removed, the vegetation can soon recover to reduce harm to surroundings.
Advantages:
1. Simple installation
There is no need to do welding or surface treatment, which saves time and cost. You just need to drill. Generally speaking, it just takes one day to install one screw pole mount system with 100-200 ground screws.
2. Large-scale application scope The screw pole mount system is suitable for different soils, like soft soil, bed rock, swamp and slope with more than 30°..
3. Spiral pile mounting system can work together with different support structures. The ground screw can be made according to client`s requirements.
4. Adaptable for different environment and environmental-friendly
There is no need to do much preparation for installation and there is no harm to environment during installation. Besides, ground screw can protect PV equipment and can be recycled.
5. Convenient transformation
Screw pole mount system can be transformed easily without damage to vegetations. Additionally, it is simple to reinstall.
the advantages of ground-screws for mounting solar photovoltaic systems
-Usually less invasive and landscape-altering than traditional mounting systems such as the half A-frames that are typically installed on cement slabs
-Screws can be easily adjusted to less serious gradients so mounting-frames are installed level: less complicated earthwork and engineering involved as compared to cement slabs
-More aesthetically pleasing than a cement mounting platform: shade-tolerant grasses and plants can easily grown beneath them
