Installation of steel structures, steel structures, Peng Jian (certified), Huizhou Steel Co., Ltd., Dongguan City, Peng was built by steel. Steel Co., Ltd., Dongguan City, Peng Jian (dgpengjian.cn) is specialized in the "Steel" of the enterprise, the company adhering to the "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Xu. Should note the following points in the factory process: ①, end milling planing to design requirements, after cutting to be grinding at the local grievance with the angle grinder. ②, drilling holes and especially the group of rows of holes, requiring accurate pitch, can be used drilling, stacked plates can be used to send drilling method. After drilling burrs should be removed. ③, planing welding groove with a planing machine planing, planing groove. Can not be used planing machine and planer planing bevel steel prices, available semi-automatic cutting machines out of the slope, and then to grinder grinding, must pay attention to the correct bevel angle planing. After the materials approach, to be in batches, classification release, should not be used immediately neatly stacked and covered with canvas or plastic sheets. To keep dry must be laid sleepers material may not touch the ground. Semi-finished steel lifting. Using 25t crane tires. Before lifting should press the bomb line on the template design requirements, the use of single specimens of lifting when lifting, lifting point four-point lashing steel, lashing point applications where a soft material pad to prevent damage to steel members. When lifting the first member hanging about 50cm off the ground, then slowly rose hook, hanging to the bridge over the members, and then slipped the rope so that it is aligned rotary member mounting portion steel structure design, slowly off the hook when, after taking place Temporary fixed spot welding, whilst hung vertically correction hammer examination, in line with the design and specification requirements before welding. The anti-corrosion coating on steel processing research in recent years, the extraordinarily rapid development of steel buildings. Steel is widely used also revealed a series of shortcomings, the more serious is the steel corrosion. Corrosion protection of steel structures were reviewed. With the extensive use of steel construction, steel structure itself due to the characteristics of the steel structure installation, and based on the architecture of security and durability of steel corrosion problem has become increasingly prominent. At present, the world each year due to the economic losses caused by corrosion of steel has been up to hundreds of billions of dollars; but due to an accident caused by corrosion of steel endanger the safe operation of the structure, the corrosion caused by a catastrophic accident has a lot to see. For welded steel structures and steel structures to withstand greater stress situations, and under stress, the corrosion will be faster.
