This is one of our core competencies. Based on our experience with large enterprises such as Changan and Weichai, we specialize in the construction of heavy steel frames for buildings with long spans and high loads. From single-span (portal) frames to multi-story steel frame structures, we not only ensure that the stringent load-bearing requirements of large equipment (such as stamping lines and general assembly) are met, but also that they are fully compatible with complex industrial piping and crane girder systems.
Designed for heavy-duty power applications, the GVU valve block is precision cast from high-strength alloy steel. The surface of the block undergoes a special anti-corrosion treatment, which ensures structural stability and tightness even at temperatures down to -50 °C.
This oil pan is manufactured using solid stamping technology with uniform wall thickness and strong welds, which effectively prevents oil leakage and vibration fatigue damage. Specially designed for use in low temperature environments using steel that is resistant to cold brittle fracture. The lower part is reinforced with stiffening ribs, increasing impact strength.
This series of brackets is made according to a modular principle, which ensures quick installation and flexible adjustment. The brackets are suitable for fixing various industrial equipment. The main material is high-strength Q345B steel, the load-bearing capacity significantly exceeds industry standards. The thickness of the zinc coating is at least 80 microns, which guarantees protection against corrosion caused by deicing agents in Siberian winter conditions.
Pipes are made of food grade stainless steel 304/316L. The internal surface is smooth, without burrs, which ensures low hydraulic resistance and low tendency to form deposits. The pipes are especially suitable for heating and hot water systems in cold regions. Welding is performed using automatic argon arc welding, the seams are smooth and tight.
This steel bed is welded from cold-rolled square tubes. The design is stable, does not make creaks, and can withstand loads of up to 300 kg or more. The surface is treated with electrostatic spraying - the coating has high adhesion, wear resistance and scratch resistance, does not peel off or rust even in conditions of high humidity or low temperatures.
Relying on the strong industrial potential of one of the key industrial centers of China, Chongqing Huaxia Windows & Doors Co.,Ltd and Chongqing Huaxia Steel Structures Co., Ltd. have joined forces to create a dual business structure: “Energy Efficiency in Building + Intelligent Manufacturing in Heavy Industry.” We specialize in the production of painted steel windows with poured insulation, fiberglass windows and high-efficiency energy-efficient windows.
