機柜一般是冷軋鋼板或合金制作的用來存放計算機和相關控制設備的物件，可以提供對存放設備的保護，屏蔽電磁干擾，有序、整齊地排列設備，方便以后維護設備。機柜一般分為服務器機柜、網絡機柜、控制臺機柜等。

　　Cabinets are generally made of cold-rolled steel plates or alloys to store computers and related control equipment. They can provide protection for the stored equipment, shield electromagnetic interference, arrange the equipment in an orderly and tidy manner, and facilitate future maintenance of the equipment. Cabinets are generally divided into server cabinets, network cabinets, console cabinets, etc.

　　常見機柜顏色有白色、黑色和灰色。（其中又分很多種類型，如橘紋、細沙紋等）；機柜按材質來分，有鋁型材的機柜、冷軋鋼板機柜、熱軋鋼板機柜；按照加工工藝來分，有九折型材機柜和十六折型的機柜等。

　　Common cabinet colors include white, black, and gray. (Among them, there are many types, such as orange pattern, fine sand pattern, etc.); Cabinets are classified by material, including aluminum profile cabinets, cold-rolled steel plate cabinets, and hot-rolled steel plate cabinets; According to the processing technology, there are nine fold profile cabinets and sixteen fold cabinets.

　　板材種類、涂層材料、加工工藝決定了機柜的穩定性。一般它的長度規格有600，800mm，寬度規格有600，800，1000mm，高度規格是42U，36U，24U。早期所用的機柜大都是用鑄件或角鋼經螺釘、鉚釘連接或焊接成機柜框架，再加由薄鋼板制成的蓋板(門)而成。這種機柜的體積大、笨重、外形簡陋，已被淘汰。隨著晶體管、集成電路的使用和各種元器件的超小型化，機柜的結構也向小型化、積木化方向發展。機柜已由過去的整面板結構發展成為具有一定尺寸系列的插箱、插件結構。插箱、插件的組裝排列方式分水平排列和垂直排列兩類。機柜材料普遍采用薄鋼板、各種斷面形狀的鋼型材、鋁型材及各種工程塑料等。機柜的框架除用焊接、螺釘連接外，還采用粘接工藝。

　　The type of board, coating material, and processing technology determine the stability of the cabinet. Generally, its length specifications are 600800mm, width specifications are 6008001000mm, and height specifications are 42U, 36U, and 24U. The cabinets used in the early days were mostly made of castings or angle steel connected or welded into cabinet frames with screws, rivets, and then covered with thin steel plates (doors). This type of cabinet is bulky, bulky, and has a simple appearance, and has been phased out. With the use of transistors, integrated circuits, and the ultra miniaturization of various components, the structure of cabinets is also developing towards miniaturization and building blocks. The cabinet has evolved from a full panel structure in the past to a plug-in box and plug-in structure with a certain size series. The assembly and arrangement of plug-in boxes and plugins can be divided into two types: horizontal arrangement and vertical arrangement. The materials commonly used for cabinets include thin steel plates, steel profiles with various cross-sectional shapes, aluminum profiles, and various engineering plastics. The frame of the cabinet is not only connected by welding and screws, but also by adhesive technology.

　　機柜按構件的承重、材料及其制造工藝的不同，可分為型材和薄板兩種基本結構。

　　Cabinets can be divided into two basic structures: profiles and thin plates, depending on the load-bearing capacity of their components, materials, and manufacturing processes.

　　①型材結構機柜：有鋼型材機柜和鋁型材機柜兩種。鋼形材機柜由異型無縫鋼管為立柱組成。這種機柜的剛度和強度都很好，適用于重型設備。由鋁合金型材組成的鋁型材機柜具有一定的剛度和強度，適用于一般或輕型設備。這種機柜重量輕，加工量少，外形美觀，得到廣泛應用。

　　① Profile structure cabinet: There are two types of cabinets: steel profile cabinets and aluminum profile cabinets. The steel cabinet is composed of special-shaped seamless steel pipes as columns. This cabinet has good rigidity and strength, making it suitable for heavy equipment. Aluminum profile cabinets composed of aluminum alloy profiles have certain rigidity and strength, and are suitable for general or lightweight equipment. This type of cabinet is lightweight, requires less processing, has a beautiful appearance, and is widely used.

　　②薄板結構機柜：整板式機柜，其側板為一整塊鋼板彎折成形。這種機柜剛度和強度均較好，適用于重型或一般設備。但因側板不可拆卸，使組裝、維修不方便。彎板立柱式機柜的結構與型材機柜相似，而立柱則由鋼板彎折而成。這種機柜具有一定的剛度和強度，適用于一般設備。根據需要機柜還裝有機柜附件。其主要附件有固定或可伸縮的導軌、鎖緊裝置、鉸鏈、走線槽、走線架和屏蔽梳形簧片等。

　　② Thin plate structure cabinet: A full plate cabinet, with its side plate formed by bending a single steel plate. This cabinet has good rigidity and strength, and is suitable for heavy or general equipment. However, due to the non removable side panels, assembly and maintenance are inconvenient. The structure of the bent plate column cabinet is similar to that of the profile cabinet, and the columns are bent from steel plates. This type of cabinet has a certain degree of rigidity and strength, and is suitable for general equipment. The cabinet is also equipped with cabinet accessories as needed. Its main accessories include fixed or extendable guide rails, locking devices, hinges, cable trays, cable racks, and shielding comb shaped spring plates.
