Steel Angle - one of the key elements in construction and metal structures. Knowing the exact weight per meter is necessary for calculating loads, delivery costs, and installation. In this article, you will learn how to quickly determine the weight of an angle using formulas and an online calculator, as well as find tables for popular sizes according to GOST standards.
Types of Steel Angles: Equal Leg and Unequal Leg
According to the profile shape, angles are divided into:
- Equal Leg (GOST 8509-93) - both legs have the same width (e.g., 50x50x5).
- Unequal Leg (GOST 8510-86) - legs of different widths (e.g., 100x75x6).
How to Calculate Angle Weight
Formula for calculating the weight of 1 meter of an angle
Weight of 1 meter of angle (kg) = (leg width A + leg width B - leg thickness S) × leg thickness S × 0.00785.
Example for angle 50x50x5: (50 + 50 - 5) × 5 × 0.00785 = 3.77 kg/m.
Table of Weight for Popular Angles According to GOST
- Angle 40x40x4: 2.42 kg/m
- Angle 50x50x5: 3.77 kg/m
- Angle 63x63x5: 4.81 kg/m
- Angle 75x75x5: 5.82 kg/m
The reference book takes into account GOST and TU standards in our calculator calculations and weight tables:
- GOST 8509-93: Hot-rolled equal leg steel angles.
- GOST 8510-86: Hot-rolled unequal leg steel angles.
- GOST 19771-93: Bent equal leg steel angles.
- GOST 19772-93: Bent unequal leg steel angles.
FAQ: Frequently Asked Questions
What is the weight of a 100 mm angle?
It depends on the thickness: 100x100x10 - 15.1 kg/m; 100x65x7 - 8.03 kg/m.
What is the difference in weight for an unequal leg angle?
The formula takes into account the different leg widths: (A + B - S) × S × 0.00785.
Conclusion
Use professional calculators and GOST tables to avoid errors. For complex calculations, we recommend consulting metallurgical engineers.
