What Do U Channel Steel Sizes Represent?
U-channels, also known as U-shaped channels or simply U-channels, are versatile structural components used in a variety of applications across different industries.These channels are characterized by their U-shaped cross-section, which provides strength and rigidity while remaining relatively lightweight.A U-channel is a type of metal profile that features a U-shaped cross-section.
Carbon Steel U Channel Steel sizes are usually expressed as width × height × thickness. And all the values are given in millimeters(mm).
Each dimension affects structural behavior.Even small changes in thickness can significantly influence load capacity.
For engineering work, size selection is not only about fitting drawings.It also determines stiffness, weight, and connection behavior.
Common U Channel Steel Sizes in mm
These U Channel Steel standard sizes and mechanical properties help engineers and distributors select the right grade for their projects.
U Channel Steel is produced in a wide range of sizes. Below is a U Channel Steel standard sizes chart showing common steel U channel sizes in mm (width × height × thickness):
40 × 20 × 3 mm
50 × 25 × 4 mm
100 × 50 × 5 mm
150 × 75 × 6 mm
200 × 80 × 8 mm
In the industry project,smaller sections are often used as secondary supports.Larger sections appear in platforms and framing systems.
U Channel Steel Weight per Meter
Section weight has a direct impact on logistics, erection work, and dead load calculations.
In early design phases, engineers usually rely on approximate figures.
Minor weight differences are common in practice.
They result from manufacturing standards and allowable tolerances.
Engineering Example: Choosing a Size
Consider a light steel platform with a span of 2 meters.
The applied load is uniform and remains within a moderate range.
Under these conditions, a 100 × 50 × 5 mm U Channel usually meets structural requirements.
A thicker section would increase stiffness.
It would also add unnecessary weight and cost without providing additional structural benefit.
