在建筑鋼材中，根據不同施工用途，鋼材的種類也是不一樣的，其中包含了方管。那么對于想要購買的使用者來講，方管性能、工藝要求以及保存內容是怎樣的呢？
In construction steel, according to different construction purposes, the types of steel are also different, including square tubes. So for users who want to buy, what are the performance, process requirements and storage contents of square tube?
方管性能
Square tube performance
塑性是指金屬材料在載荷作用下，產生塑性變形（永久變形）而不破壞的能力。
Plasticity refers to the ability of metal materials to produce plastic deformation (permanent deformation) without damage under load.
硬度是衡量金屬材料軟硬程度的指針。目前生產中測定硬度方法較常用的是壓入硬度法，它是用一定幾何形狀的壓頭在一定載荷下壓入被測試的金屬材料表面，根據被壓入程度來測定其硬度值。
Hardness is a pointer to measure the hardness and softness of metal materials. At present, the common method for measuring hardness in production is the indentation hardness method. It uses an indenter with a certain geometry to press into the surface of the tested metal material under a certain load, and determines its hardness value according to the degree of indentation.
以很大速度作用于機件上的載荷稱為沖擊載荷，金屬在沖擊載荷作用下抵抗破壞的能力叫做沖擊韌性。
The load acting on the part at a great speed is called impact load, and the ability of metal to resist failure under impact load is called impact toughness.
強度是指金屬材料在靜荷作用下抵抗破壞（過量塑性變形或斷裂）的性能。
Strength refers to the resistance of metal materials to failure (excessive plastic deformation or fracture) under static load.
方管工藝要求
Process requirements for square tube
1、方管必須在專用進口流水線上進行制作，以確保風管制作精度及風管的密閉性。
1. The square pipe must be manufactured on the special import assembly line to ensure the manufacturing accuracy and tightness of the air pipe.
2、方管配件的下料應在進口專用機器上運用計算機軟件全自動化完成，并由進口的鈑金專用等離子切割機上完成自動等離子切割工序。
2. The blanking of square pipe fittings shall be completed automatically by using computer software on the imported special machine, and the automatic plasma cutting process shall be completed by the imported special plasma cutting machine for sheet metal.
3、方管的咬口連接應采用進口自動咬合器進行咬合工藝。等等。
3. The bite connection of square pipe shall adopt imported automatic bite device for bite process. wait.
方管保存
Square tube preservation
方矩管貨物的場地或者發電站，應取舍正在干凈腌臜、排水通順的中央，遠離發生無害氣體或者粉塵的廠礦。正在場地上要肅清荒草及所有雜品，維持鋼材腌臜。
The site or power station of rectangular tube goods shall choose the center that is being cleaned, pickled and drained smoothly, and be far away from factories and mines where harmless gas or dust occurs. Clean up weeds and all sundries on the site and maintain the steel pickling.
重型型鋼、鐵軌、辱謄寫鋼版、大口徑竹管、標準件等能夠室外堆放。
Heavy section steel, rail, steel plate, large-diameter bamboo pipe, standard parts, etc. can be stacked outdoors.
中中型型鋼、盤條、鋼骨、中口徑竹管、鋼絲及鋼絲繩等，可正在透風優良的料小棚寄存，但必需上苫下墊。
Medium and medium-sized section steel, wire rod, steel bone, medium diameter bamboo pipe, steel wire and steel wire rope can be deposited in the material shed with excellent ventilation, but they must be covered and padded.
一些中型鋼材、薄謄寫鋼版、鋼帶、硅片、小口徑或者薄壁竹管、各族熱軋、冷拔鋼材以及價錢高、易侵蝕的非金屬制品，可寄存入庫。
Some medium-sized steel products, thin transcribed steel plates, steel strips, silicon wafers, small-diameter or thin-walled bamboo tubes, hot-rolled and cold drawn steel products of all ethnic groups, as well as high-priced and erodible non-metallic products, can be deposited and warehoused.
庫房應依據天文環境選出，正常采納一般開啟式庫房，即有房頂有圍子、窗門縝密，設有透風安裝的庫房。
The warehouse shall be selected according to the astronomical environment, and the general open warehouse shall be adopted normally, that is, the warehouse with roof, enclosure, careful windows and doors and ventilation installation.
庫房請求晴天留意透風，下雨天留意開放防潮，時常維持適合的貯存條件。
The warehouse is required to pay attention to ventilation in sunny days, open to moisture in rainy days, and maintain suitable storage conditions from time to time.
