 Iron Bridge - Shropshire, England

 Cast iron is strong in compression. That's why early arch bridges were made of cast iron.
 * Iron Compression Message**

Cast iron is brittle -- it snaps without warning.
 * Iron Tension Message**

//__***Steel Properties* **__// Ingredients: Iron with a touch of carbon
 * Type**: High-strength steel

Strengths: One of strongest materials used in construction, strong in compression and tension Weaknesses: Rusts, loses strength in extremely high temperatures
 * Steel**


 * Steel Applications**
 * Cables in suspension bridges


 * Trusses

<span style="font-size: 120%; color: rgb(0, 128, 128);">Sears Tower - Chicago, Illinois <span style="color: rgb(0, 128, 128);"> Steel is stronger than any other material in compression. That's why engineers choose steel beams and columns to support most skyscrapers.
 * Example:**
 * Steel Compression Message**

Steel is stronger than any other material in tension. That's why the cables in the Golden Gate Bridge are made of steel.
 * Steel Tension Message**

Is a building material composed of sheets of hot-dip galvanised mild steel, cold-rolled to produce a linear corrugated pattern in them.
 * What corrugated iron is?**

It is cheap, easy to transport, durable, strong, supple and available everywhere!
 * Characteristics**

During the 1850s corrugated houses where transported from England. It has always been extremely popular in Australia because is cheap, easily transportable and replays it more expensive materials. <span style="color: rgb(0, 128, 128);"> **What it takes to be an iron worker?** Structural Iron workers have to be in Good physical conditions and to have great force, because this type of work is frequently done at great height, also the should have agility and balance. Structural Iron workers may become supervisers or going to bussines for themselves. **
