One of the most important types of joists is the steel joist, a modern marvel that makes your home sturdy and long-lasting. Now, let’s get up close and personal with the unsung hero of your home, the steel joist.

The Flange: The Powerhouse of the Joist

Think of the flange as the superhero cape of the steel joist. It’s those wide, flat sections on the top and bottom of the joist that do all the heavy lifting. When your home bears down on the joist, the flange channels the force like a lightning rod, directing it away from the vulnerable center and into the strong, supportive beams that hold your home together.

Imagine the flange as a super-strong shield protecting the core of the joist from bending and breaking. It’s like the armor of a valiant knight, defending the joist from the weight of your furniture, your energetic kids, and even that elephant you keep in the attic (just kidding about the elephant).

So, when you’re thinking joists, remember the flange—the unsung hero that keeps your home standing tall and proud, even when it’s facing the weight of the world.

Joists: The Invisible Heroes of Your Home’s Structure

In the hidden depths of your home, there’s a network of silent heroes working tirelessly to keep your roof overhead and your feet on the ground: joists. These unsung structural workhorses are the backbone of your home, but most of us never give them a thought… until something goes wrong!

Spanning the Distance
