Product Description:

1、Structure of Hollow Section Description: 

Hollow section is a type of metal profile with a hollow tubular cross section. Hollow section, especially rectangular sections, are commonly used in welded steel frames where members experience loading in multiple directions. Square and circular hollow section have very efficient shapes for this multiple-axis loading as they have uniform geometry along two or more cross-sectional axes, and thus uniform strength characteristics. This makes them good choices for columns. They also have excellent resistance to torsion. Hollow section can also be used as beams, although wide flange or I-beam shapes are in many cases a more efficient structural shape for this application. However, the hollow section has superior resistance to lateral torsional buckling.

2、Main Features of the Hollow Section: 

• High manufacturing accuracy

High strength

Small inertia resistance

Strong heat dissipation ability

Good visual effect
