Hollow Structural Steel (HSS) is a type of structural steel that is often used in construction. It is characterized by its hollow tube-like shape, which makes it lightweight, durable, and ideal for a wide range of applications.
There are several different types of HSS, including:
1. Round HSS: This is perhaps the most common type of HSS, featuring a cylindrical shape that is ideal for column and beam applications.
2. Square HSS: Similar to round HSS, square HSS is flat on each side and is often used in architectural and ornamental applications.
3. Rectangular HSS: This type of HSS is rectangular in shape and is ideal for use in structural applications where a wider range of sizes is needed.
4. Elliptical HSS: This type of HSS has an oval shape and is ideal for use in architectural applications where a unique shape or design is desired.
