Aluminum square tube can be generally divided into four types, this article will introduce you.

1. U-shaped aluminum square: U-shaped aluminum square pass is directly formed by the machine or artificial cold bending forming, the length of the machine formed aluminum square pass within 6 meters, the bottom width of 200mm, the height of 400mm, generally can meet the needs of the current market, artificial aluminum square pass in the height, thickness, the choice of the bottom width is not limited, but the labor cost is high, so generally less used. Only when the size of the machine is exceeded will this processing method be chosen.

2. Profile aluminum square: profile aluminum square is directly extruded by the machine according to the relative size of the grinding tool, the product in hardness, straightness, the overall effect is better than U-shaped aluminum square, because each size needs to have a corresponding mold, if you need to customize, you need to customize grinding tool reproduction.

3. Arc aluminum square: arc aluminum square is a special aluminum square with aluminum profiles drawn and bent by the machine directly in accordance with the arc. The thickness of its profile will require a little thicker.

4. Modeling aluminum square: modeling aluminum square refers to the irregular shape, the line has ups and downs, the need to burn welding and other special aluminum square, the product time consuming, material consumption is relatively large, generally made of thicker materials, in some special design or special requirements of the occasion will be used, the cost is high, the decoration style is distinct, the artistry is strong.

First of all, we should look at the material of aluminum square pass. Bad aluminum square pass material is definitely unqualified in quality. Processing aluminum square pass products with such materials is definitely very low in grade. The above three materials decline in turn.

The production process of aluminum Fangtong products is also very important. For the poor aluminum Fangtong products, it will directly affect the applicable life.

Aluminum square pass surface treatment methods have a variety of, including spraying, roller coating, coating, painting four methods, spraying and painting treatment of aluminum square pass material in the service life is relatively short, there will be color difference in the surface treatment, roller coating product color uniformity, but need to be decorated before the actual style, not easy to fade, discoloration, And the film can basically guarantee the effect of 10 years of stability without discoloration.
