方管分类及用途

　　Classification and use of square tubes

　　一、方管的分类

　　1、 Classification of square tubes

　　方管是一种中空的方形管材，常用的材质包括钢、铝、铜等不同金属材料，根据尺寸和厚度的不同，可以分为以下几类：

　　Square tube is a type of hollow square pipe, commonly used materials include different metal materials such as steel, aluminum, copper, etc. Depending on size and thickness, it can be divided into the following categories:

　　1. 方钢管：是指壁厚大于等于2.0mm的方形钢管，一般的规格为20*20mm、25*25mm、30*30mm等。

　　1. Square steel pipe: refers to a square steel pipe with a wall thickness greater than or equal to 2.0mm. The general specifications are 20 * 20mm, 25 * 25mm, 30 * 30mm, etc.

　　2. 方管矩管：是指壁厚小于2.0mm但大于等于1.0mm的方形钢管，规格有10*20mm、15*30mm、20*40mm等。

　　2. Square tube rectangular tube: refers to a square steel pipe with a wall thickness of less than 2.0mm but greater than or equal to 1.0mm, with specifications of 10 * 20mm, 15 * 30mm, 20 * 40mm, etc.

　　3. 薄壁方管：是指壁厚小于1.0mm的方形钢管，规格有10*10mm、15*15mm、20*20mm等。

　　3. Thin walled square tube: refers to a square steel pipe with a wall thickness of less than 1.0mm, with specifications of 10 * 10mm, 15 * 15mm, 20 * 20mm, etc.

　　4. 镀锌方管：是指经过热浸镀锌处理的方形管材，可以增强方管的耐腐蚀性能，常用于室外设施和构筑物。

　　4. Galvanized square pipe: refers to square pipes that have undergone hot-dip galvanizing treatment, which can enhance the corrosion resistance of square pipes and is commonly used in outdoor facilities and structures.

　　5. 不锈钢方管：是指用不锈钢材质生产的方形管材，具有较好的耐腐蚀性能和美观度，一般用于高端建筑装饰。

　　5. Stainless steel square tube: refers to a square tube made of stainless steel material, which has good corrosion resistance and aesthetics, and is generally used for high-end building decoration.

　　二、方管的用途

　　2、 The purpose of square tubes

　　方管广泛应用于建筑、机械制造、电力设备、太阳能、汽车制造、船舶建造、化工工业、运动器材等领域。以下是方管的常见用途：

　　Square tubes are widely used in construction, mechanical manufacturing, power equipment, solar energy, automotive manufacturing, shipbuilding, chemical industry, sports equipment and other fields. The following are common uses of square tubes:

　　1.建筑领域：方管是建筑结构中不可或缺的构件，主要用于搭建架子、支撑框架、搭建隔墙、围挡等。

　　1. In the field of architecture: Square tubes are indispensable components in building structures, mainly used for building shelves, supporting frames, building partitions, fences, etc.

　　2.机械制造：方管适用于各种机械、电器设备中，如汽车底盘、汽车门窗、机器床、贮槽、通风管等。

　　2. Mechanical manufacturing: Square tubes are suitable for various mechanical and electrical equipment, such as car chassis, car doors and windows, machine beds, storage tanks, ventilation pipes, etc.

　　3.电力设备：方管也可应用于电力设备制造，如电线槽、开关箱、电缆桥架、输电塔架等。

　　3. Power equipment: Square tubes can also be used in the manufacturing of power equipment, such as wire ducts, switch boxes, cable trays, transmission towers, etc.

　　4.太阳能光伏：方管可以用于太阳能光伏板架的支架和接口，长期承受阳光、雨水等自然环境。

　　4. Solar photovoltaic: Square tubes can be used as brackets and interfaces for solar photovoltaic panels, and can withstand natural environments such as sunlight and rainwater for a long time.

　　5.化工工业：方管在化工工业中也有广泛应用，如注塑机、气源设备、传送带等。

　　5. Chemical industry: Square tubes are also widely used in the chemical industry, such as injection molding machines, gas source equipment, conveyor belts, etc.

　　以上仅是方管应用的部分场合，随着人们对材料技术的不断研究和应用，方管的用途会变得更广泛和多样化。
