HongKong-Zhuahai-Macao Bridge would be completed at the end of year 2017, according to recent news. Thanks to all of engineers as well as various materials like the steel products ERW steel pipe and seamless steel pipe, this huge bridge now is in our life.
Ive been here in Zhuhai at August, 2017 and Ive seen this huge and long bridge by myself. Which shocked me at that time. It is here crossing the whole sea and with all of original materials. I think the steel products appear would be the best answer for the complete of this huge bridge. First of all, we know that this long bridge has to hold on the weight of the long distance transportation, and all those steel products strength gives possibility for the strength of the bridge needs. Second, we know that there are lots of wind on the sea. And resistance of corrosion would be one of the most important role for the building of the whole bridge. And of course, galvanized steel products can provide this guarantee.
Thanks to the wise engineers and also the high quality steel products so that we can get the distance short between Hong Kong, Zhuhai and Macao.

Produced by Chongqing Hesheng Longgang Technology Co., Ltd. (manufacturer) Basalt fiber reinforcement (new material to replace reinforcement) Product Description: basalt fiber reinforced bar (BFRP) is a new composite material formed by pultrusion process. It is made of basalt fiber as reinforcement, resin, filler and curing agent. Now it has been widely used in construction, highway and bridge constructionã?? Basalt fiber reinforcement can completely replace ordinary steel reinforcement and deformed steel; Compared with ordinary reinforcement, it has strong advantages: (see Annex for technical parameters) 1. The cost is the same as that of ordinary reinforcement; 2. The strength is 200% of the ordinary reinforcement with the same specification and diameter; The tensile strength reaches 1100mpap; The reinforcement is only 450MPa, 3. Basalt fiber reinforcement, especially with high acid, alkali and corrosion resistance, is a kind of electrical insulator that will never rust. 4. Basalt fiber reinforced bar, which is non-magnetic. It has high tolerance to the moisture concentration in cement mortar and the penetration and diffusion of carbon dioxide, and can prevent the corrosion of concrete structure in harsh environment, so as to improve the durability of buildings and bridges. 5. The specific gravity of basalt fiber reinforcement is 2.1g/cm3; The specific gravity of steel and reinforcement is 7.85/cm3; The diameter weight of the same specification is 370% lighter than that of steel reinforcement, and the strength is 200% of that of steel reinforcement. 6. The physical properties of basalt fiber reinforcement are higher than that of steel reinforcement, and the cost is the same as that of steel reinforcement, which is of epoch-making significance to replace steel reinforcementã??
Duplex 2205 is a nitrogen-enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels. Duplex ? describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless. The structure of 2205 duplex stainless steel consists of austenite pools surrounded by a continuous ferrite phase. In the annealed condition, 2205 contains approximately 40-50% ferrite. Often referred to as the work horse grade, 2205 is the most widely used grade in the duplex family of stainless steels The advantage of a duplex structure is that it combines the favorable qualities of a ferritic alloy (stress corrosion cracking resistance and high strength) with those of an austenitic alloy (ease of fabrication and corrosion resistance). Usage of 2205 Duplex stainless steel should be limited to temperatures below 600 F. Extended elevated temperature exposure can embrittle 2205 stainless.
Duplex 2507 is a super duplex stainless steel designed for applications which demand exceptional strength and corrosion resistance. Alloy 2507 has 25% chromium, 4% molybdenum, and 7% nickel. This high molybdenum, chromium and nitrogen content results in excellent resistance to chloride pitting and crevice corrosion attack and the duplex structure provides 2507 with exceptional resistance to chloride stress corrosion cracking. Usage of Duplex 2507 should be limited to applications below 600�?�° F (316�?�° C). Extended elevated temperature exposure can reduce both the toughness and corrosion resistance of alloy 2507. Duplex 2507 possesses excellent mechanical properties. Often a light gauge of 2507 material can be used to achieve the same design strength of a thicker nickel alloy. The resulting savings in weight can dramatically reduce the overall cost of fabrication. The advantage of a duplex structure is that it combines the favorable qualities of a ferritic alloy (stress corrosion cracking resistance and high strength) with those of an austenitic alloy (ease of fabrication and corrosion resistance). Usage of 2205 Duplex stainless steel should be limited to temperatures below 600 F. Extended elevated temperature exposure can embrittle 2205 stainless
