Company Introduction:
Jiaxing City Qunbang Hardware Co, Ltd is a production\design\sales and after-sales as one of the fasteners business, The company is located in HangjiaHu Plain, close to Shanghai\Ningbo\Zhapu ports. The geographical position is superior, the transportation is convenient, has created the natural superiority for the export.
The company mainly produces high-strength fasteners business, bolts and nuts are the main, the main standard are DIN/ANSI\ASME/JIS/UNI/ISO/AS/BS/GB and so on. The product massively applies in the bridge\road\the petroleum pipeline facility\the wind power generation and steel structure project. Carbon steel bolts mainly have 4.8, 5.8, 6.8, 8.8, 10.9, 12.9, nuts mainly have 4, 6, 8, 10, the main material of stainless steel fastener is 201\304\316. QBH from its establishment to he present, after ten years of development, it is equipped with perfect testing equipment, and SGS and TUV have a good cooperation, each batch of products is accompanied by a 3.1 or 3.2 certificate, further escort the quality of the company.
In 2017, we registered the trademark "QBH" in the China\EU\United States, and has six fastener product patents, has obtained the Zhejiang Province science and technology small and medium-sized enterprise certificate as well as the ISO9001: 2000 cerfiticate. With the continuous development and expansion of the company, as well as customer demand for product diversification, on the basis of its original production, in order to further enhance the potential for cooperation with customers, as well as to provide competitive prices.
