People use rectangular tubes in many industries. These tubes offer strength and a modern look. Manufacturers choose them for building, furniture, and machines. Their flat sides make welding and joining easy. So they become a popular choice for many projects.

Steel pipes serve many industries. You need the right type for your project. Two common options are ERW pipe and seamless pipe. They look similar but differ greatly. Understanding these differences saves time and money.

A square tube is a hollow steel section with four sides. People use it everywhere in modern construction and design. You see it in buildings, furniture, and machines. Its shape gives unique strength and flexibility.

Steel pipes need protection from rust and corrosion. Manufacturers use zinc coating to achieve this goal. This process extends the pipe's lifespan significantly. But two main methods exist for applying zinc. These methods create pre-galvanized and hot-dip galvanized pipes. Each type serves different applications and budgets.

People often confuse hot dip pipe with GI pipe. Both types resist corrosion. But they differ in process, coating thickness, and durability. Let us explain the key differences clearly.
