Angle iron is a length of iron bent at a right angle along the centre of the length of the piece of iron. This produces a piece of structural iron with that has strength in two directions. The angle iron offers more strength than a flat iron or even round iron rod. Understanding the specifications of the angle iron helps the home builder select the proper materials for the job.
Size specifications for angle iron use three measurements. The first two measurements indicate the width of each of the two flat sides of the angle iron. These are commonly identical measurements, such as 1 inch by 1 inch. The third dimension is the thickness of the piece of iron.
Angle iron is commonly available in lengths up to 20 feet at commercial metal shops. Angle iron is cut to length using hacksaws or power chop saws. Builders can use ratios to calculate the weight of any length of any size of angle iron. The ratios specify the weight of either 1 inch or 1 foot of iron, depending on the source. The builder multiplies the length of angle iron they plan on using times the appropriate ratio.
Angle Iron Production
Angle iron is produced by either cold- or hot-rolling flat pieces of iron. Cold-rolling entails, as the name suggests, forming the final angle iron piece by rolling it between forms while the steel is at a temperature below malleability. Hot-rolled angle iron is shaped while at a higher temperature. Hot-rolled angle iron holds its shape better, according to Serious Fencing.
