Square-shaped Hollow Iron Pipe

According to its shape, hollow pipes are also often referred to as square pipes. This type of iron pipe is often used as a material for making gates or fences. However, nowadays, most people seem to prefer to use hollow pipes for ceiling frames or house canopies.

Compared to wooden frames, the use of hollow pipes as a ceiling frame certainly provides more benefits. This pipe is easier to install and is stronger and does not rot easily. In addition, hollow pipes are also fire resistant, making the house safer from fire hazards.
