Where should we start from when buying high-quality square tubes?
As for how to choose high-quality rectangular tubes, I would like to share my opinion, hoping to have some reference for you. What kind of high-quality square tube is a trustworthy product or service? Many people have doubts about the mass of high-quality square tube.
First, look at the material.
The square rectangular tubes are made of many kinds of materials, and the performance of square tubes made of different materials is not the same. Therefore, the square tubes made of corresponding materials must be selected according to the specific requirements of the house project, so as to ensure its applicability.
Secondly, check whether the weld on the surface of the square tube is tightly welded
Not all square tubes are seamless square tubes. Some square tubes are made by welding. Therefore, when purchasing, check whether the welding seams are tight. Square tubes that are not tightly welded are not easy to use.
Again, check whether the large surface of the square tube is rusty.
Some square tubes will rust due to improper storage. The seriously rusted square tube will greatly affect the quality of the square tube, so once it is found that there is serious rust on the surface, it should not be used again. Of course, only a slight rust treatment on the surface will not affect the quality.
4. Preferred manufacturer of regular square tube
After all, wholesale purchasing managers should pay attention to the price situation. If you can cooperate with regular manufacturers, you can enjoy both the wholesale price of direct sales of manufacturers and the after-sales service of manufacturers. In addition, if you want to customize and process different types of profiles and have additional requirements for size, you should also communicate with the manufacturer in advance, so that the profiles purchased later can truly meet our needs. Some small manufacturers will reduce raw materials to a certain extent in order to better reduce product costs. Alas, although such products are cheap, it is better not to buy them.
5. You should know some performance parameters of the square tube and the situation of the factory.
First of all, we can see that in order to have good efficiency, we must first grasp the plasticity of square tubes. Generally speaking, the plasticity of square tubes refers to the ability of square tubes to deform without being destroyed under pressure. It plays an important role. Secondly, the hardness should be reasonably planned and arranged when selecting. If the hardness is weak, even if the elasticity is good, there will be many disadvantages when dealing with some strong pressure. When selecting square tube, pay attention to select some products with good fatigue performance. When we use it, we will find that due to the efficiency of the product itself, to some extent, our metal parts are insufficient. These problems need our special attention and treatment. Some good products can largely avoid problems, and also make our use more convenient and reasonable.
The product inspection certificates, quality control certificates, honors and engineering cases owned by the enterprise. This reflects the factory's product quality and after-sales guarantee from the side. It's also quite reassuring.
