Hongxin has worked with the Yellow River steel structure for many times, which is also to promote the common discussion of the two corporate cultures. Recently, the Yellow River steel structure In recent years, with the development of economic construction, the application of steel structure in civil buildings is more and more, with the development of economic construction, the application of steel structure in civil buildings is more and more, with the application of steel structure in practical engineering experience and design theory research increasingly Widely, and steel structure manufacturers continue to launch new steel structure products, the application of steel structure in multi-storey civil buildings is growing day by day, for example, the application of composite floor in multi-storey civil buildings, on the basis of not reducing the structural safety index, can reduce the beam height, plate thickness, reduce the structural self weight and earthquake effect, and can obtain larger building space, to meet the building requirements Compared with reinforced concrete, it has higher economic value. The large-scale production of rolled H-beam, the diversification of floor bearing plate, the maturity of anti-corrosion coating and fire retardant coating also create a wide space for the application of steel structure of multi-storey civil buildings, and at the same time cooperate with Hongxin company to help the Yellow River steel structure reform material problem. This time, our company purchases the steel ball recycling machine, which greatly saves the remaining dirt during production, Huanghe steel structure is very satisfied and appreciates Hongxin Dajia. Thanks for the trust of Huanghe steel structure to Hongxin. In the future, Hongxin will enhance the cooperation with Kaifeng Huanghe Steel Structure Co., Ltd!

　　This machine is a mobile vacuum cleaner. It adopts the vacuum absorption principle to collect the bulk materials. It has great suction, simple operation, self-propelled equipment, self-cleaning electric control and touch electric control box. 4 kg iron bar can be sucked up once, and the equipment can recover 3.5 tons of 3 mm steel sand per hour. The lifting height of the material can be up to 10 meters. It can be used horizontally. The straw can be extended by 50 meters. The adsorption effect is still good. This product has won the third prize of science and technology progress of the Ministry of machinery industry.
