Is it better to use square tubes or round tubes for stainless steel security windows?
The anti-theft windows nowadays are no longer just for preventing theft, but more for preventing falling, protecting the safety of family members, and protecting the safety of passers-by. So is the variety of stainless steel anti-theft windows made of round tubes or square tubes, which is more robust? How should we choose?
Stainless steel anti-theft windows are generally available in two materials on the market, 201 and 304 stainless steel. Compared with 304 stainless steel, the two materials are more corrosion-resistant and durable, but the relative price is higher than that of 201.
Which is stronger, stainless steel square tube or round tube? The comparison mainly lies in the magnitude of the resistance moment of the two in the horizontal situation. For example, a 50*50mm stainless steel square tube has an actual thickness of 2mm and a resistance moment of 5.48; a 51mm stainless steel round tube of the same material has an actual thickness of 2.5mm and a resistance moment of 4.4. Therefore, a stainless steel tube of the same material is more round than a square tube. The tube has a large resistance moment and is stronger. This is because the square tube has four 90-degree angles. For example, a 1mm iron plate with a length of 300mm may not be able to withstand 1 kg of pressure, but two 1mm iron plates can withstand at least 100 kg after being welded at 90 degrees. , If there is no 90 degrees, the endurance will be halved.
In conclusion, the square tube of stainless steel anti-theft windows is stronger than the round tube. To make the same anti-theft window, use square pipes and round pipes of the same material and thickness. The cost of square pipes is higher than that of round pipes. Therefore, in general, the manufacture of anti-theft windows is a combination of round pipes and square pipes. The square tube is used as the frame and the round tube is used as the lining. The quality and appearance are very good, and it will be generally welcomed by consumers. In addition, pay special attention to whether it is firm or not during installation.
