flat bar

​​​​​
Flat bars are commonly used in various industrial and construction-related applications. They are distinguished by their rectangular cross-sectional shape and evenly distributed surface along their sides.
The structure and geometry of the flat bar make it well suited as a component for construction, assembly, and reinforcement of various structures. Its even and flat surface enables easy attachment and creates stability in joints and assemblies.

Flat bars are usually made of different materials such as steel, aluminum, or stainless steel. The dimensions of the flat bar can vary depending on the application area and the requirements of the project.
​​​​​​​
In the construction industry, flat bars are often used to create frames, reinforce structures, manufacture scaffolds, and hold together various components. In addition, it is used in the manufacturing sector to create machine parts, transportation equipment, and interior details.

Flat Bar Dimensions

Stainless steel flat bar

'Stainless flat bar is used in environments with higher corrosivity classification than flat bars of s355 steel. Huddinge Steel does not stock stainless flat bar but it can be ordered.

ALUMINUM FLAT BAR

Aluminum flat bar is used in environments with higher corrosivity classification than flat bars of s355 steel but they do not have the same ability to carry loads. Huddinge Steel does not stock aluminum flat bar but it can be ordered.

Further Information:
  • Width and thickness are measured at a point at least 100 mm from the end of the bar.
  • Straightness is measured over the total length of the bar (L).
  • The right angle is measured as the difference between u and the nominal value for width (b).
