Steel is inherently more flame resistant.
Steel is still the material of choice because: Steel is not "STEEL" It comes in many strengths, hardnesses, crack and fatuige resistance types.
Steel I beams
If it is stainless steel, it will be rust resistant.
Steel is stronger.
composite deck
Corrosion resistance is the first thing that comes to mind.
9GA is thicker than 12GA when it comes to metal.
Yes. Actually... a diamond is NOT 'stronger' than steel. A diamond is 'harder' than steel, but it is not stronger.
Steel is stronger than nylon
Among our handy steel beam tables you can find standard beams' dimensions and beams' weights, steel hollow sections tables and other steel profiles data.
No. Concrete is a mixture of cement and other elements. Reinforced concrete often includes iron or steel beams in it to make it stronger.
Because steel has a high cost/strength density. In other words, its cheap to use when you take into account that you don't have to use as much of it. And steel has many favorable properties, unlike wood, steel will normally give some indication that it is going to fail (crack, deformation, etc.) where as wood will just break. This is good because it gives you a chance to fix the problem before it becomes life threatening.
