1.What is angle steel?
Steel angle, also named angle iron, or steel angle bar, is basically manufactured by hot-rolled carbon steel or high strength low alloy steel. It has L-cross shaped section with two legs - equal or unequal and the angle would be 90 degree.
2.How strong is angle steel?
With a single, 90° bend, angle iron is one of the strongest structural support elements. That's because it evenly distributes stress along its entire length and resists bending.
3.Is angle iron easy to bend?
When A-iron is twisted from one end or the other, that is when its structural integrity is most vulnerable. Simply, A-iron is hard to bend, but easy to twist.
4.What's the purpose?
The benefits of angle iron correspond to its material, length, thickness, width and purpose. But, you also need to consider the force applied, the weight carried and the torsion resisted.
The Internet is filled with calculators and charts to determine the ability to support weight, capacity and deflection in various angle iron lengths, widths and materials. It's important to start with a clear understanding of the engineering demands, mechanics specifications and tensile conditions that apply. For example, try to picture an angle at work amidst forces:
Combined forces press simultaneously against the whole piece from the inside, and those forces vary along the width of the side.
Weight distributes its force along and down the angle's length.
External pressures push against the angle as a concerted force that varies in strength across the angle.
Multiple forces test the angle for twist and torque.
5.What's the price?
You can buy some angle iron or products in any "big box" hardware store. However, if you're looking for specialty or structural products, you need to be familiar with the pricing.
The more steel involved in the length, width and thickness, the more you will pay.
Cost reflects the quality or nature of the steel involved.
Finishes like textures or coatings add expense.
Shipping and delivery can be a real and significant cost.
