Market of SS Rebars prospects well
The rebar is the most widely used steel raw materialin construction field. With the rapid social sustainable development and stainless steel reinforcement increasingly used, and gradually replaced the ordinary carbon steel reinforced the status, the market has a good prospect.
Over the years, our country hot-rolled ribbed reinforcement constantly improve the level of. Steel and iron industry development policy explicitly pointed out to promote Ⅲ level (400 MPa) and above level ribbed reinforcement, speed up the hot rolling out 335 MPa hot-rolled steel with strength, to the areas where earthquakes are building, building infrastructure, and key projects, force the use of more than 400 MPa and strength of steel. Using ultra-fined grain or micro alloying, etc, on the building of large steel production in large and medium-sized enterprises of production line, and promote the reform of building steel upgrading. Nowadays, strength 400 MPa reinforced already is widely used, Shanghai 400 MPa reinforced YingYongLiang of more than 50%. At the same time,stainless rebar sprung up, and more and more is valued by the market, a number of key buildings adopt stainless reinforce bar reinforcement.
Industry insiders point, in reinforced concrete structure field stainless rebar is used to strengthen tendons, strength and resistance of the harsh Marine environment and in the concrete in the process of chloride to embed the corrosion. Corrosion resistant stainless steel concrete buildings in the ocean of bridge deck on the application, satisfy the intensity corrosion resistant and seismic requirements, no maintenance, its service life of 120 years. Stainless rebar can be used in the bridge pier, dock, pile foundation, prevent slope dike, carrying out system, is the gear, the ramp, railing. In many industry fields, some corrosion of the high demand of the base structure of important equipments, also must use high strength and corrosion resistance of the stainless steel reinforcement. The city infrastructure, such as pedestrian Bridges and reinforced concrete structure using stainless steel.
Stainless rebar in bridges and coastal highway, high speed railway, and other important infrastructure project, the application effect is notable. In the water, the coastal environment, or in the ice on the highway salt pollution place, chloride in concrete with the entire range migration in the structural design of the steel in life, thus make obvious within the corrosion problems and lead to expensive structure of the maintenance costs. But, stainless reinforce bar has good corrosion resistance and can be well applied to these in major corrosion of the reinforced concrete structure environment.
At present, some domestic large steel enterprises attach importance to the researchment and production of stainless reinforce bar. There’s one stainless steel factory successfully trial-produced 316 L, 2205, 2304, the stainless steel ribbed reinforcement, and transportation ministry unit and highway institute of science related application research cooperation. The bridge with stainless steel reinforcement and development and application of "by the transportation ministry unit for the traffic construction project in western science and technology project", for the stainless steel reinforcement, stainless steel wire into roads, Bridges industries laid a foundation.
We believe, with the domestic gradually increasement of demand about stainless rebar , the stainless rebars will have a good market.
