Question:

Is it good to choose a steel tube or an aluminum tube?

Such questions. Recently prepared to buy an umbrella with the baby, too heavy to hold for a long time can not stand. Taobao took a look, the style is colorful. I saw 3 stalls tent, but there are two kinds of pipes, do not know what kind of practical. Steel pipe should be relatively strong and durable, the aluminum tube is characterized by light, but worried that the baby sit on top of instability. How do moms choose?

Answer:

If less than one year old treasure is lying, over a year old in light, look down is not easy, steel heavier, lighter aluminum, are generally quite solid but before a lie you drop Sanle is not expensive, do not use long long time will fall a few, and I know for all is this, is not recommended to buy
Aluminum tubes are mainly divided into the followingAccording to the shape of: square tube, round tube, pattern tube, special-shaped tubeIt can be divided into seamless aluminum tube and common extrusion pipe according to extrusion methodAccording to the precision points: ordinary aluminum tube and precision aluminum tube, in which the precision aluminum tube generally needs to be processed after extrusion, such as cold drawn, fine drawn, rollingBy thickness: ordinary aluminum tube and thin-walled aluminum tubePerformance: corrosion resistance, light weight.
The umbrella car is better than the aluminum tube.The heat exchange of aluminum is faster than that of steel, so the cooling speed is faster and the cost is almost the same as steel. Because aluminum will not rust, so the latter does not need steel platoon, as rust preventive maintenance.
