When is it Better to Use US Iron Instead of Hollow?

In the world of construction and fabrication, the choice of iron type greatly affects the strength of the structure, cost efficiency, and aesthetics of the final result. Two types of materials that are often compared are AS Iron (or Angle/Solid Iron) and Hollow Iron. Although both are in the form of bars, their characteristics and functions are very different. So, when should you use AS Iron rather than hollow?

Understanding the Basic Differences
AS Iron is a solid iron bar in the shape of a square or round that has high strength and is not hollow.

Hollow Iron is iron in the form of a square or rectangular tube with an empty (hollow) inside.

When is AS Iron More Suitable for Use?
When Maximum Structural Strength is Needed
Because it is solid, AS iron is very suitable for use as structural supports, machine mounts, or frame parts that receive heavy loads directly.

For Precision Engineering Applications
AS Iron is often used in industrial machine components, heavy racks, and heavy steel construction that requires high tensile and compressive strength.

Welding and Turning Work
Because the material is solid, AS iron is more stable during the turning or welding process. This is important in the fabrication of components that need further processing.

Extreme Environment
US iron is more resistant to pressure and is not easily dented. Suitable for heavy industrial areas or locations with high impact risks.

When is Hollow More Efficient?
Non-structural architectural work such as canopies, fences, partitions, suspended ceilings.

Light aesthetic needs, because hollow looks neater and lighter.

Small-scale projects that do not require heavy loads but still want sturdy and economical results.
