Channel beam is an important element for construction and mechanical engineering. Its weight directly affects the calculation of loads and the project cost. In this article, you will find size tables according to GOST 8240-97, learn the difference between hot-rolled and bent profiles, and also learn how to quickly calculate the mass using an online calculator.
GOST 8240-97: standard for steel channel beams
According to GOST 8240-97, steel channel beams are divided into two types:
- Hot-rolled (series P, U, E) - high precision
- Bent equal leg - made of sheet steel
The marking includes a number (height in cm) and a letter: for example, channel beam 16P has a height of 160 mm and parallel flanges. The weight per meter depends on the wall thickness and varies from 10.4 kg (10P) to 36.5 kg (30P).
Table of weight for popular channel beams
Let's calculate the mass for popular profiles used in construction:
| Type | Weight 1 m (kg) | Application |
|---|---|---|
| 10P | 10.4 | Light structures |
| 12P | 12.4 | Partition frames |
| 16P | 17.8 | Supporting beams |
| 20P | 25.8 | Industrial facilities |
How does the online channel beam weight calculator work?
To calculate the mass without formulas:
- Choose the profile type (hot-rolled/bent) from the directory.
- Specify the height and wall thickness.
- Enter the length in meters.
The service will automatically determine the weight according to GOST and offer supplier options. This is especially convenient when working with non-standard sizes, for example, for bent equal leg channel beams.
