A jerrycan might seem like just a fuel container, but its impact goes far beyond that. Originally designed in 1930s Germany for military use, it revolutionized fuel transport with its durability, efficiency, and ease of use. Unlike earlier fuel cans that required extra tools and funnels, the jerrycan introduced smart design features—from its triple-handle grip to its airtight, spill-proof construction. Its design was so effective that it was widely adopted by both Axis and Allied forces during World War II, and its influence is still seen today in both military and civilian applications worldwide.

Steel and Concrete: A Blueprint for Connection

April 23, 20252 min read

One of the materials used to build bridges is concrete. Another is steel. Separately, they’re useful—but together, they’re unstoppable.

Now let me tell you something fascinating about these two. Concrete is incredibly strong—until you try to pull it apart. It can take on massive pressure, but when placed under tension, it cracks and crumbles. On the other hand, steel is the opposite. It doesn’t handle pressure all that well, but it’s excellent when stretched. Strong in tension, weak in compression.

But when you combine them? You get steel-reinforced concrete—a material strong enough to carry skyscrapers and long-span bridges, yet flexible enough to sway with earthquakes and heavy winds without collapsing.

Here’s the even more mind-blowing part: steel and concrete expand and contract at exactly the same rate when exposed to heat or cold. In engineering terms, they share an identical coefficient of expansion. Whether in the desert heat or arctic freeze, they move together. No warping. No splitting apart. They were made to stay connected.

Concrete and Steel Bridge Construction

Coincidence? I don’t think so.

In his book Business Secrets of the Bible, Rabbi Daniel Lapin shares a powerful insight in Secret #4: The universe was created for connection. When we look at steel and concrete, we’re not just looking at two materials—we’re witnessing a divine design for partnership. Two elements with opposite strengths, created to complement each other perfectly.

Think about it. This is the blueprint of every great team, every strong relationship, every enduring organization. We’re not meant to do everything alone. Just like concrete needs steel to handle tension, and steel needs concrete to handle pressure, we need each other. Our differences aren’t obstacles—they’re opportunities for synergy.

At BridgeD Inc., this is what we believe to our core. Creativity doesn’t thrive in isolation. Confidence doesn’t grow in a vacuum. Connection isn’t just nice—it’s necessary. Whether we’re bridging gaps in industry, education, or community, we believe people were made to work together. To support each other. To build something stronger than we ever could alone.

So next time you see a bridge or a tall building, remember—those structures stand not because of one material, but because of two that were meant to be connected.

And maybe, just maybe, so are we.

Be Creative. Be Confident. Be Connected.
