This is from John Tulipano: For once, I was in the right place at the right time—but it turned out to be a small fire. Around 8:50 AM on April 18th, 2014, Glenside Fire Department received a call about a dryer fire at 644 Burdette in Glendale Heights. I was just two blocks away, at North Ave and Glen Ellyn Road, when I got the dispatch. As I made my way down the street looking for the address, DuComm reported that everyone had already left the house and flames were coming from the dryer. I passed by the house and saw the homeowner and kids outside as I pulled over. The Glendale Heights police were pulling up behind me. Engine 58 and Medic 59 arrived about two minutes later, stretched a 1-3/4-inch attack line, and quickly knocked down the fire as more units showed up. In my rush to get things set up, I forgot to check my ISO settings and ended up taking all the photos at 2500, which was slightly overexposed. But thank goodness for RAW files and Lightroom!

The steel angle is a carbon structural steel for construction. It is section steel with a simple cross-section. It is mainly used for metal components and the frame of the workshop. It is required to have good weldability, plastic deformation performance and certain mechanical strength in use. The raw steel billet for the production of angle steel is a low-carbon square billet, and the finished angle steel is delivered in the form of normalized or hot rolled.
Steel angle bar can be made into pressure structural bracket based on different size and grade, and also can be made into connector between structural beam. Widely used for various building structures and engineering structures, such as house beams, bridges, power transmission towers, lifting, and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench brackets, power piping, busbar bracket installation, and warehouse shelves.
Equal and unequal are the two major types of steel angle:
Steel angles are fashioned using a single Flat Steel section and bending it, generally at a 90-degree angle with both legs the same size. See below for a rundown of the different steel angle types:
Equal angle
Equal steel angles have 2 axes` that are the same length, hence their name. They are the most common types of steel section and can be made to various specs and cut to any size, making them extremely versatile. Their sizing is represented by side A x side B x thickness.
Unequal angle
Unequal steel angles are also right-angled; however, they have different sized axis` making them L-shaped. This section is much stronger (up to 20%) with a much higher strength to weight ratios. Their sizing is represented by side A x side B x thickness.
