Concrete Stairs, vs Steel Stairs. Which One is Better?

Stairs play an integral part in every multi-level structure. Not only are stairs important in design, but so is the material used.

You can make stairs from wood, stone, or other materials. But concrete and steel are used most often for industrial and commercial stairs. This article will focus on the similarities and distinctions between concrete stairs and steel stairs.

How do concrete stairs differ from steel stairs?

The main difference between concrete and steel stairs is the base materials. Concrete stairs are made entirely from concrete. Steel stairs are made principally from steel. There are many benefits and costs to both materials depending on what they are used for. Steel stairs are usually lighter, stronger, and more flexible than concrete stairs.

  • Steel is made from iron, carbon, and various other materials. Galvanizing steel for staircases often includes a zinc coating, which prevents corrosion. In other instances, stainless steel, which is naturally resistant to corrosion, may be used for construction.
  • Concrete comprises three components. Water, aggregate (rocks, sands, or gravel), powdered, and cement. When cement is mixed with water or aggregate, it acts as glue and concrete will harden once it has been poured.


There are also differences in concrete stairs and steel stairs.

  • Steel staircases can be found in indoor areas of homes, offices, and factories. You can also build outdoor stairs with steel, especially if you use galvanized stainless steel. Steel is a popular choice for building crossover, alternating tread, and mezzanine staircases in industries, as well as spiral staircases for homes and commercial buildings.
  • Concrete Staircases Are popular for outdoor usage but can also be used in commercial or residential buildings as the base of stairs that are later covered with other materials. Concrete is typically used for more basic types such as straight or L-shaped stairs.

Concrete stairs vs steel stairs comparison

1. Concrete stairs vs. stainless steel stairs durability & strength


Both concrete and steel stairs have a long life expectancy. Depending upon the environment, each type can have its advantages or disadvantages.

Steel is the best material to use for stairs construction. Steel stairs have high tensile strengths, which means they resist breaking under tension. Galvanizing steel resists corrosion and increases its durability, particularly in outdoor environments with extreme weather. Steel is nearly five times stronger than concrete and can be able to support excess weight. A steel staircase is far stronger than a concrete staircase and can be built with far less material than concrete.

Concrete has a high degree of compression. It resists being pushed together. Concrete is not as strong as steel in terms of tensile resistance. Concrete staircases sometimes have hidden metal reinforcing and rebar bars. Concrete stairs are able to withstand heavy loads and high impacts, and will not rust under wet conditions.

2. Concrete vs. steel stairs. Which one is the easiest to maintain?

Both concrete and steel stairways are easy to maintain. Steel stairs require little maintenance. To prevent rusting, outdoor steel staircases can also be galvanized. They can then easily be cleaned using a pressure washer. A sponge or mop might be a better option if the steel is powder-coated. This will prevent any damage to the finish. To clean steel stairs indoors like mezzanine staircases, you can use a mild detergent to sweep or mop.


Concrete stairs, like metal stairs, are also easy to maintain. To get rid of dirt and grime, concrete stairs can be easily mopped indoors. Outdoor concrete stairs can be pressure washed without causing any damage.


In certain cases, however, concrete stairs or steel staircases with concrete treads could be an advantage. Concrete is fireproof, making it a great choice for fire escape stairwells. Concrete stairs can be used for soundproofing, heat absorption, and heating cost reduction because they are noise- and heat-resistant.
