无论是在各大工程中还是生产中，总会有剩余的方管，如果一直进行堆积不加于防护就非常容易的被破坏，那么会对方管厂家造成严重的损失，所以在对方管进行保管时，一定要注意合理的进行保管。 保管方管的场地或仓库，应选择在清洁干净、排水通畅的地方，远离产生有害气体或粉尘的厂矿。在场地上要清除杂草及一切杂物，保持方管干净。

Whether in major projects or in production, there will always be surplus square pipes. If the accumulation is not added to the protection, it will be very easy to be destroyed, which will cause serious losses to the other side's pipe factory. Therefore, when keeping the other side's pipe, we must pay attention to reasonable storage. The site or warehouse under the custodian's control should be located in a clean and smooth drainage area, away from factories and mines that produce harmful gases or dust. Weeds and all debris should be removed from the site and square tubes should be kept clean.

一些小型方管、薄钢板、钢带、硅钢片、小口径或薄壁钢管、各种冷轧、冷拔方管以及价格高、易腐蚀的金属制品，可存放入库;库房应根据地理条件选定，一般采用普通封闭式库房，即有房顶有围墙、门窗严密，设有通风装置的库房;库房要求晴天注意通风，雨天注意关闭防潮，经常保持适宜的储存环境。

Some small square pipes, thin steel plates, steel strips, silicon steel sheets, small caliber or thin-walled steel pipes, various cold-rolled, cold-drawn square pipes and high-priced and corrosion-prone metal products can be stored in warehouses; warehouses should be selected according to geographical conditions, generally using ordinary closed warehouses, that is, warehouses with walls on the roof, close doors and windows, and ventilation devices; warehouses require attention to ventilation in sunny days, rainy days. Attention should be paid to damp proof and proper storage environment should be maintained.

在仓库里不得与酸、碱、盐、水泥等对方管有侵蚀性的材料堆放在一起。不同品种的方管应分别堆放，防止混淆，防止接触腐蚀;大型型钢、钢轨、辱钢板、大口径钢管、锻件等可以露天堆放;中小型型钢、盘条、钢筋、中口径钢管、钢丝及钢丝绳等，可在通风良好的料棚内存放，但必须上苫下垫。

No corrosive materials such as acid, alkali, salt and cement should be stacked together in the warehouse. Different kinds of square pipes should be stacked separately to prevent confusion and contact corrosion; large-sized steel, rails, disgraced steel plates, large-caliber steel pipes, forgings, etc. can be stacked in the open air; small and medium-sized steel, wire rods, reinforcing bars, medium-caliber steel pipes, steel wires and wire ropes, etc., can be placed in well-ventilated material shed, but must be upholstered and underlayed. 综合来讲，在对方管进行保管时，存放环境是最重要的，只有存放环境有所保障，那么对于方管才能进行很好的保护。

Generally speaking, the storage environment is the most important when the other party keeps it. Only when the storage environment is guaranteed, can the management be well protected.

方管执行国家标准GBT 6728-2002 结构用冷弯空心型钢尺寸，外形，重量及允许偏差生产，是Q345B带钢经过工艺处理卷制而成。方管在于它的材质Q345B材料(低合金)生产加工而成与普通方管在原材料材质(Q195,Q215,Q235)有很大的区别，一般是把Q345B带钢(低合金)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常用长度为6米，12米量大可根据客户要求定尺加工。一般小规格是50根每包，大规格在4根每包不等重量控制在3吨左右。方管在现货方面以大规格居多在80MM*80MM-500MM*500MM，厚度在3MM-16MM。

The square tube is produced by cold-formed hollow section steel with dimension, shape, weight and allowable deviation for the implementation of national standard GBT 6728-2002. It is made of Q345B strip steel by coiling after process treatment. Square pipe is made of Q345B material (low alloy), which is very different from ordinary square pipe in raw material material material (Q195, Q215, Q235). Generally, Q345B strip steel (low alloy) is unpacked, flattened, crimped, welded to form round pipe, then rolled into square pipe by round pipe and cut into square pipe with the required length of 6 meters. The size of 12 meters can be fixed according to customer requirements. General small specifications are 50 per pack, big specifications are 4 per pack with unequal weight controlled at about 3 tons. In spot, square tubes are mostly of large size in 80MM * 80MM - 500MM * 500MM, thickness in 3MM - 16MM.

方管是方管的一个比较重要的类型的，在各种的市场发展和各种的应用中都是在不断地进行增强的。因此的话建议厂家要多多注意方管的制作方法和质量，这样的话会有更多市场行情的!

Square management is an important type of Square management, which is constantly strengthened in various market developments and applications. Therefore, it is suggested that manufacturers should pay more attention to the manufacturing methods and quality of square tubes, so that there will be more market conditions!
