round pipes

Steel Pipes in Curtain Wall Systems:

• Curtain walls are non-structural, outer coverings of a building, usually made of glass and supported by a steel or aluminum framework. Sometimes, steel pipes may be used as part of this framing system, though typically, structural steel elements like beams, columns, or channels are involved. In this case, "steel curtain pipes" might be a term someone uses to describe the smaller pipe components used in such systems.

Pipes for Fencing or Barriers (Curtain as in Shield or Barrier):

• In construction or industrial settings, "curtain" might be used to describe a barrier or shield made from steel pipes. These types of pipes could be used to create protective walls or partitions in industrial applications (e.g., construction site barriers, safety screens, etc.).

Steel Pipes for Decorative or Architectural Uses:

• In some artistic or architectural contexts, pipes are used as part of a design element for "curtain-like" structures, often serving as a decorative frame or screen.
