Square pipes, as the name suggests, are a type of square steel pipe that is a common material in the industrial construction industry. From the current development, not only is the demand for square pipes greatly increasing in the industrial and construction industries, but also other industries are increasingly using square pipes. In order to meet people's needs, the types of square pipes are also increasing, and the number of people selling square pipes is also increasing. The quality of square pipes sold by these merchants is also quite different, Therefore, we must learn some knowledge about selecting square tubes. Choosing high-quality square tubes can improve the quality of manufactured products, and high-quality square tubes can also improve the safety factor.

對方管有所了解的人都知道方管是具有一定的抗拉、抗壓性能的，因此我們在選擇方管時也可以從這幾個方面進行考慮。

People who have some knowledge of square pipes know that square pipes have certain tensile and compressive properties, so we can also consider these aspects when selecting square pipes.

抗拉性是方管基礎的性能，因此抗拉強度越大代表方管的性能越好，因此我們選擇抗拉強度較大的方管可以讓方管帶給我們更大的幫助。

Tensile strength is the fundamental performance of square tubes, so the higher the tensile strength, the better the performance of square tubes. Therefore, choosing square tubes with higher tensile strength can help us more.

當然方管還有其它的特性，其它特性指的就是抗壓和抗彎性能，我們在挑選方管時要從這三個方面進行考慮，不能只注重一個方面，只有全面考慮才能讓自己挑選出較好的方管。

Of course, square tubes have other characteristics, which refer to their compressive and flexural properties. When selecting square tubes, we should consider these three aspects and not only focus on one aspect. Only by comprehensively considering can we choose a better square tube.

此外，在面對市場上多種多樣質量不同的方管時我們還應該對方管的廠商進行一番篩選，選擇信譽度高質量好的廠家才能讓自己挑選出來的方管更有保障，選擇這樣的廠家在我們使用方管的期間如果出現問題才能得到融洽的解決。因此在購買方管時選擇一個信譽度高的廠家也是非常重要的。在此華鎳公司可提供材料難題咨詢以及方管和其它鋼材的供給。

In addition, when facing a variety of square tubes with different quality in the market, we should also conduct a screening of the manufacturers of the square tubes. Only by selecting reputable and high-quality manufacturers can we ensure that the square tubes we have selected are more reliable. If there are any problems during our use of square tubes, we can find a harmonious solution. Therefore, it is also very important to choose a reputable manufacturer when purchasing square tubes. Here, Huani Company can provide consultation on material problems and supply square tubes and other steel materials.
