Hollow Pipe (Holo): Definition, Types, and Applications
What is a Hollow Pipe (Holo)?
A Hollow Pipe, or Holo, is a steel tube with a square or rectangular cross-section. Although it is not round, it is still called a pipe because of its hollow interior. In the steel industry, the term “pipe” refers to all hollow sections, whether circular, square, or rectangular.
Hollow sections are widely recognized in the construction industry for their strong structure, high precision, and versatile applications. This material is often chosen as a building framework, architectural support, and even as a base material for modern furniture that emphasizes both strength and aesthetics.
Types of Hollow Pipes
Black Hollow
Black Hollow is made from carbon steel without any additional protective coating. Its natural dark color comes from the steel itself. This type is ideal for indoor applications such as ceilings, partitions, or structures that will be coated with paint or finishing layers.
Galvanized Hollow
Galvanized Hollow is coated with zinc to protect the steel from rust and corrosion. Because of its durability against moisture and weather, this type is commonly used for outdoor applications such as canopies, fences, railings, billboards, and roofing frames.
Applications of Hollow Pipes
The applications of hollow pipes are highly diverse, making them a top choice in various construction projects as well as interior design.
- In construction, hollow pipes are commonly used for canopies, ceiling frames, partitions, fences, stair railings, and lightweight steel roof structures.
- In the interior field, they are often utilized for tables, chairs, shelving, and home decoration elements.
- For outdoor use, galvanized hollow pipes are more recommended thanks to their resistance to weather and corrosion. Meanwhile, black hollow pipes are better suited for indoor applications, especially on structures that will be coated with additional finishing.
