Steel Staircase
Steel is one of the least expensive materials you can use for stairs. The material itself is less expensive than alternatives like concrete or wood. Installation tends to be cheaper, too, since the metal fabricators can create the stairs off-site before installing them.316 stainless steel possesses very high corrosion-resistance and is used for staircase railing design. It requires almost zero maintenance and can easily be used in extreme environmental conditions.Hands down, straight stairs are the simplest and cheapest type of staircase. Stairs that run in a straight line are affordable and easy for builders to install.
