ABOUT USAbout us

徐州新兴达克罗科技有限公司为专业生产M16以上的国家标准、国际标准以及非标准高强度螺栓连接副的厂家。产品包括各种六角螺栓、双头螺栓、地脚螺栓以及球接点网架螺栓、螺母、垫片。2004年与达克罗涂覆（锌铬涂层GB/T18684-2002）国家标准制定单位南京宏光空降装备厂合作，开始对外加工、生产达克罗涂覆（锌铬涂层）的产品并开展达克罗技术咨询服务。因达克罗（锌铬涂层）抗腐蚀性能高出普通镀锌5－7倍，盐雾试验可在1000小时以上，在生产过程中无排放、避免了电镀过程中氢脆现象，是国际流行的国家鼓励发展的环保型生产工艺（环发[1999]185号文件，项目编号为99B030），所以是代替表面氧化、电镀锌、电镀镉、热镀锌和锌合金镀层等传统表面处理的必然趋势。

　　2007年随着我国高速铁路及客运专线项目的实施，公司又引进了多元合金共渗（真空渗锌）技术装备，产品现已批量应用在京沪高铁、甬台温、合武、京石等客运专线。

　　徐州新兴达克罗科技有限公司愿以全新的经营理念，本着“以质量求生存，以信誉求发展”的原则，竭诚为各行各业的新老客户服务！

　　Xuzhou Xinxing Fastener Technology Co., Ltd. Is a manufacturer specializing in producing M16 or higher national standards, international standards and non-standard high strength bolt connection pairs. The products include all kinds of hexagonal bolts, double-headed bolts, anchor bolts, and ball contact grid bolts, nuts, gaskets. In 2004, in cooperation with Nanjing Hongguang Airborne Equipment Factory, the national standard-setting unit of Dacromet Coating (Zinc-Chromium Coating GB/T18684-2002), Dacromet Coating (Zinc-Chromium Coating) began to process and produce Dacromet Coating (Zinc-Chromium Coating) products and provide Dacromet technical consulting services. Because the corrosion resistance of Dacromet (zinc-chromium coating) is 5-7 times higher than that of common galvanizing, salt spray test can be done for more than 1000 hours, no emission is produced in the production process, and hydrogen embrittlement is avoided in the electroplating process. It is an environmentally friendly production process encouraged by the international popular country (Document No. 185 of Circular Development [1999], Project No. 99B030), so it replaces surface oxidation, galvanizing and cadmium plating. The inevitable trend of traditional surface treatment such as hot-dip galvanizing and zinc alloy coating.

　　In 2007, with the implementation of China's high-speed railway and passenger dedicated line projects, the company also introduced multi-alloy co-infiltration (vacuum zinc infiltration) technology and equipment. The products have been batch applied in Beijing-Shanghai high-speed railway, Yongtaiwen, Hewu, Beijing-Shijiazhuang and other passenger dedicated lines.

　　Xuzhou Xinxing Fastener Technology Co., Ltd. Is willing to serve new and old customers in all walks of life wholeheartedly with a brand-new management concept and the principle of "survival by quality and development by reputation".
