Product Description:

We mainly engaged in manufacturing PHC concrete piles with diameters of Φ600~Φ1400 for wharf. Every year, the company produces various types of concrete piles of over 150,000 meters with single-section pile of 41meter long and annual gross output value up to RMB 600 million.
With years’ manufacturing experience of concrete piles and a great number of excellent technological and management talents, the company persists in technical innovation and research of new products. The large-diameter PHC concrete piles with merits such as good bending strength, large bearing capacity, fine resistance against the external force and so forth have been the preferential choice of structural materials for foundation engineering construction  such as large ports, wharfs, shipyard, huge bridges, high-rise buildings, heavy factories, high-speed railway, etc.
The company holds the operation philosophy of “honest, practical and harmonious for win-win” and persists in the quality guideline of “constant improvement with prohibition of non-conforming products into construction site” to provide you sincerely with superior products and service.

Q:Steel Barns..........?
Barns can be constructed out of a number of materials be it steel, block or wood. Among all the available materials, steel offers the best in terms of strength, durability and pricing. Constructing a barn using wood can be a costly task because of the high price of wood. On the other hand, constructing a barn using block consumes more time and involves a much more professional approach thereby increasing the labor costs. Considering all these factors, it is always recommended to go for steel barns due to their durability, robustness and longer life span.
Q:Why not use stainless steel to make coins?
Stainless steel has been used by some countries to make coins, but it's not an ideal metal. When a coin is struck, a die comes down and strikes the blank with many tons of force (the blank is also sitting on top of another die--one has the image on the obverse (front) of the coin, while the other die has the image of the reverse of the coin). When the die strikes the blank, the force causes the metal in the blank to flow into the recesses of the die. The problem with stainless steel is that it doesn't want to flow into the die. To get an image, either the relief (how high the raised portion of the design will be) has to be very low, and the coin has to have a simple design, or they have to greatly increase the pressure of the strike. This slows the coining press down, and greatly shortens the life of the dies.
Q:Advantages and disadvantages of stainless steel
Stainless steel is the main advantage of corrosion resistance or high temperature, general acid resistant medium, as well as heat resistance, high temperature oxidation (heat resistant skin) of high temperature stainless steel.
Q:Are there any differences between the two prices of I-beam and H steel?
The flanges of Wuxi H steel are of equal thickness, have rolling section, and have a combined section composed of 3 plates welded together. Hua Liang is a rolling cross section, due to poor production process, flange within the edge of the 1:10 slope. H type steel rolling is different from ordinary I-beam with only one set of horizontal roll, because of its wide flange and no inclination (or inclination is to be very small), a group of vertical roll and roll, therefore, the rolling process and equipment than the conventional mill complex. The maximum rolled H steel produced in China can be 800mm high and can only be welded composite sections. China's hot-rolled H steel GB (GB/T11263-1998) H steel is divided into narrow flange, wide flange and steel pile three categories, its code names are Hz, HK and hu. The narrow flange H steel is suitable for beams or columns, while wide flange h and H steel piles are suitable for axial compression members or bending members. Compared with H steel, the W, IX and iy are better than H steel under equal weight condition.
Q:What's the use of steel sheets on both sides of the transformer?
Under normal circumstances, the magnetic leakage is too large, can not play the function of transformers.If there is an air gap, the transformer will have a steep drop characteristic, not a transformer, and the output has constant current characteristics. The arc welding machine will adjust the welding current with the air gap.
Q:Multiple and calculation methods for channel 12
No. 12 channel specification: high 120; leg length 53; waist thickness 5.5; channel cross section area 15.36 cm^2
Q:Can lightning protection earthing steel bar be directly welded with thread steel?
Yes, but the length of the weld must be greater than or equal to 6 times the length of the steel bar, double sided welding. If one side welds, double the length of the weld. Otherwise, lightning acceptance is not up to standard.
Q:mechanical behaviour data for recycled steel?
It is not clear from the question whether the recycled steel is used in its existing state or used as raw material for further fabrication. For the existing steel, you need to track down the original documents such as the ladle analysis and mill certificates certifying the material standards for which the steel was fabricated. Another alternative is take samples and conduct chemical and mechanical tests on the steel. Also the date of when the structure was built from which the steel is recycled may help indicate whether it is (American Society for Testing and Materials) Standard ASTM A7 or ASTM A36 or another type of steel. In most cases, the steel is used as raw material to make new steel. The mill will adjust the additives to produce steel with the required chemical and physical properties to meet the ASTM standards specified.
Q:How to distinguish 301 stainless steel wire, soft silk, hard silk?
In order when you can clearly inform the seller, if not required to directly buy soft sellers give you is hard to do, if you need to like shrapnel hard half hard and soft, generally consists of the seller according to your requirements of materials (annealing) treatment, so you need time the seller will be clear, soft and hard materials can be bought to.
Q:What's the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel seamless steel tube is a kind of steel strip with hollow section and without seams.
