方矩管，是方形管材和矩形管材的一种称呼，也就是边长相等和不相等的的钢管。是带钢经过工艺处理卷制而成。一般是把带钢经过拆包，平整，卷曲，焊接形成圆管，再由圆管轧制成方形管然后剪切成需要长度。方管是一种空心方形的截面轻型薄壁钢管，也称为钢制冷弯型材。它是以Q235热轧或冷轧带钢或卷板为母材经冷弯曲加工成型后再经高频焊接制成的方形截面形状尺寸的型钢。热轧特厚壁方管除壁厚增厚外情况,其角部尺寸和边部平直度均达到甚至超过电阻焊冷成型方管的水平。综合力学性能好，焊接性，冷，热加工性能和耐腐蚀性能均好，具有良好的低温韧性。

Square rectangular tube, is a name of square pipe and rectangular pipe, that is, the edge of equal length and unequal steel pipe.Ribbon steel is made through process processing roll.Generally, the strip steel is unwrapped, flat, coiled, welded to form a round pipe, and then rolled by a round pipe into a square pipe and then cut into the required length.Square pipe is a hollow square section of light thin-walled steel pipe, also known as steel refrigeration bent profile.It is the Q235 hot rolled or cold rolled strip or coil as the base material after cold bending processing and then by high frequency welding made of square section shaped steel.Except for the wall thickness and thickening, the corner size and edge smoothness all reach or even exceed the level of resistance welded cold forming square pipe.Comprehensive mechanical properties, weldability, cold, heat processing properties and corrosion resistance are good, with good low temperature toughness.

热镀锌方矩管是用钢板或者钢带经过卷曲成型之后焊接制成的方管，在热镀锌池通过一系列的化学反应成型的方管产品，我们可以通过热轧或是冷轧镀锌钢带实现冷弯，之后进行高频焊接而成的一种空心正方形截面的钢管产品。热镀锌方矩管的生产工艺相当简单，生产效率比较高，品种规格多样，设备资源较少，但一般强度是低于无缝热镀锌方矩管的。

Hot dip galvanized square moment pipe is made of steel plate or steel strip after winding forming welding square pipe, in hot dip galvanized pool through a series of chemical reaction molding of square pipe products, we can through hot rolled or cold rolled galvanized steel belt to achieve cold bending, after high frequency welding and a hollow square section of steel pipe products.The production process of hot galvanized square moment tube is quite simple, the production efficiency is relatively high, the variety and specifications are diverse, the equipment resources are less, but the general strength is lower than the seamless hot galvanized square moment tube.

热镀锌方矩管由于其优异的性能常被人们用在玻璃幕墙、电力铁塔、水及煤气的输送、电线套管及金属结构等方面，近些年更被大量地采用。热镀锌方矩管产品一般是以其外观来判断是不是合格产品的，在热镀锌方矩管的外壁表面若出现漏镀、麻点、气泡、泛绿等的频率过高，则判定热镀锌方矩管为不合格的产品。但在产品标准之中对热镀锌方矩管的偏差都有规定的范围，即尺寸是允许偏差的。热镀锌方矩管的品种丰富、规格齐全，业务遍及多个省市地区。热镀锌方矩管的产品规格、壁厚等有相关的标准要求，一切都按照使用的不同途径来具体区分。

Due to its excellent performance, hot-dip galvanized square moment pipe is often used in glass curtain wall, power tower, water and gas transmission, wire casing and metal structure, and it has been widely used in recent years.Hot dip galvanized square moment pipe products are generally on its appearance to judge whether qualified products, in the outer wall surface of hot dip galvanized square moment pipe if the frequency of leakage plating, hemp, bubbles, green, etc. is too high, the hot dip galvanized square moment pipe as unqualified products.However, the deviation of the hot-dip galvanized square moment pipe in the product standard is specified range, that is, the size is allowed to be deviation.Hot dip galvanized square moment pipe variety, complete specifications, business throughout a number of provinces and regions.Hot-dip galvanized square moment pipe product specifications, wall thickness and other relevant standard requirements, all according to the use of different ways to distinguish specifically.

方矩形焊管现在主要应用在大型场馆的建设，例如：飞机场、体育场、车站等用来作为主体钢架、墙体等，民用钢结构住宅的建设；另外在机械行业作为设备的底座和支架，车辆作为大梁和大型货车的改装，农用三轮车的车体，民用上用来焊接各种框架等。高频焊管产品应用于建筑业的主要是结构用高频焊接方矩形管和建筑用结构冷弯型钢，其中方矩形管用量占50%以上。从结构力学和经济角度，方矩形管和H型钢结合应用于建筑业是最佳组合，可以实现工业厂房和民用住宅建设工厂化。

Square rectangular welding pipe is now mainly used in the construction of large venues, such as airport, stadium, station, wall, civil steel structure housing, in addition, as the base and support of equipment, vehicles as girder and large trucks, the body of agricultural tricycles, for welding various frames, etc.High-frequency welded pipe products used in the construction industry are mainly structural high-frequency welding square rectangular pipe and building structure cold-curved steel, among which the square rectangular pipe consumption accounts for more than 50%.From the perspective of structural mechanics and economy, the combination of square rectangular pipe and H-shaped steel in the construction industry is the best combination, which can realize the industrial plant and civil residential construction factory.
