Galvanized angle iron finds extensive applications in construction, due to its robust structural properties. It is commonly used in the construction of frames, beams, and brackets, providing essential support in buildings and other structures. The corrosion-resistant properties of galvanized angle iron make it an ideal choice for outdoor applications, such as fencing, scaffolding, and framework for solar panels.

There are three different types of manholes: shallow, normal and deep. “Normal” manholes are typically 4- to 5-feet deep and wide enough for the average person to fit in. Shallow manholes are 2- to 3-feet deep, often placed at the start of a sewer branch and in areas with low traffic. Manholes with a depth greater than 5-feet are considered deep and usually have an entry method like a ladder built-in, as well as a heavier cover.
