At present, our new generation of stainless steel highway guardrail has passed the A-class, SB-class, SA-class, SS-class collision test, marking our material has in 90% of the road conditions as a guardrail material to use the qualifications, stainless steel highway guardrail to replace the traditional carbon steel highway guardrail and took a key step.
As China's important stainless steel R & D production enterprises, TISCO has always been to continue to develop new stainless steel products, expand the application of stainless steel, and promote the traditional material replacement and upgrading as its responsibility. In the context of the "dual carbon" strategy, TISCO further accelerates the expansion of low-carbon products to help cities and society to reduce carbon, increase the production and application of high strength, high corrosion resistance, high energy efficiency green products represented by stainless steel, and vigorously expand the new market of economic stainless steel, giving full play to the significant advantages of stainless steel in the whole life cycle of emission reduction and carbon reduction. Advantages, to help the national economic development of green transformation. This year, TISCO, with its outstanding advantages in the field of stainless steel, has become a special steel materials in Shanxi Province, "chain master" enterprise, "chain master" responsibility to promote the application of TISCO in the promotion of economic stainless steel to further speed up.
In fact, we have been focusing on stainless steel materials in the highway guardrail to replace the traditional material opportunities. But objectively, the cost of stainless steel material is indeed higher than traditional steel materials. Although from the whole life cycle point of view, stainless steel guardrail is more cost-effective, but the customer an increase in investment costs is inevitable, and the upgrading of national requirements for environmental protection, especially the 'double carbon' strategy proposed, to provide us with opportunities.
In order to extend the life, the traditional highway guardrail generally uses ordinary steel plus hot dip galvanizing process for anti-corrosion treatment. In the past, hot dip galvanizing process of highway guardrail and suitable for manufacturing highway guardrail of conventional stainless steel material compared to the one-time investment cost can save about 30%. For investment cost considerations, the construction unit to upgrade the material is not enough incentive. Zinc is a heavy metal pollutant, will cause pollution to water bodies (groundwater) and land, belongs to the environmental protection strict control project. With the upgrading of environmental requirements, in line with environmental requirements of the galvanized enterprises less and less, galvanized treatment prices are getting higher, the construction unit for the highway guardrail of new alternative materials began to be interested.
In this way, R & D staff to ensure that the material performance to meet the required strength of the guardrail, corrosion resistance requirements on the basis of further in-depth research and testing of the composition and production process, and finally make the highway guardrail with stainless steel materials and reduce the cost of more than 5 percentage points. Stainless steel highway guardrail service life reached two times the traditional highway guardrail, a mile outside, the investment cost only increased by more than 20%, and the whole life cycle cost than the traditional highway guardrail of hot dip galvanizing process reduced by nearly 40%, if you consider the stainless steel material can be 100% recycled characteristics, stainless steel highway guardrail economic benefits, social benefits are very considerable.
For the development of the national economy to provide more, better, more economical stainless steel green materials is the "global stainless steel industry leader" of the right. In addition to highway guardrails, TISCO's new elevator with economic stainless steel, low-cost construction stainless steel, new energy cladding stainless steel and a number of new stainless steel products have been or will be applied to the main battlefield of the national economy in various fields, TISCO people are full of pride for China's economic green high-quality development to contribute to the wisdom and strength.
