Aluminum is an excellent material to use for stairs for different reasons such as:

  • Aluminum is flexible enough to form different types of stairs, such as spiral stairs, unlike steel which is rigid and hard to bend without damage.

The stairs parts are made from extruded 6061-T6 or 6063-T6 aluminum alloy.

Follow the process below to make or build aluminum stairs:

The first step is to install the stringers of the stairs by fixing them in the location where the aluminum stairs are to be installed.

Next, attach and fix the step treads to the stringers of the stairs using a drill and self-tapping screws.

The next step is installing the stairs’ railing to protect people and items from falling off the sides.

Next, start installing the railing by fixing and screwing the posts to the ground where you want to install it.

Next, measure and cut the railing section to fit the gap between the posts of the aluminum stairs.

Lastly, attach the railing sections to the railing brackets to complete the railing installation.

You may need to install a landing to your aluminum stairs depending on the application the stairs are being used for.

Are Aluminum Step Stairs Safe?

Aluminum stairs are perfectly safe as long as you buy them from a reputable aluminum stair supplier.

An illegal aluminum stair supplier may lie about the mechanical properties and acceptable load ratings of the aluminum stair.

You will also need a professional to properly install the aluminum stair to prevent any faulty construction that can cause severe damage.

You should also install railings to the aluminum stairs to provide extra protection and prevent people or property from falling.

The American Disability Act(ADA) requires You to install risers between the steps of the aluminum stairs for extra protection.

What Kind Of Aluminum Are Stairs Made Of?

There are different types of aluminum alloys that you can use to make stairs.

But commercial aluminum stairs are mostly made from the 6000 series of aluminum, such as the 6061-T6 aluminum alloy or the 6063-T6 aluminum alloy.

The T-6 tempered 6061 and 6063 series of aluminum is mechanically and chemically sound to be used in aluminum stair applications.

The 6061 and 6063 aluminum are strong enough to carry considerable load or weight, making them perfect for aluminum stairs.

Why Is Aluminum Good For Stairs?

Aluminum is good for stairs because it has chemical and mechanical properties that are suitable for stair applications.

Aluminum is resistant to rust and corrosion, making them easier to maintain and suitable for outdoor applications.

Aluminum is also a better alternative to wood for stairs because aluminum will not degrade as fast as wood. Aluminum is also waterproof, unlike wood.  

This means aluminum is better and easier to maintain and use for stairs than wood, even though wood is cheaper than aluminum.

Aluminum is also better to use than concrete because aluminum stairs can be uninstalled and relocated, unlike concrete, which must be destroyed and remade.

Aluminum is also lighter than steel, making it easier to ship, install, uninstall, and relocate than steel.

Aluminum also has better rust and corrosion-resistant properties than steel, making the aluminum more suitable for applications exposed to the climate.

This means aluminum stairs can be used for both indoor and outdoor applications.

How Strong Is Aluminum Stairs?

There are different factors that contribute to the overall strength of aluminum stairs, such as:

  • Type of alloy used.
  • Overall size.
  • Thickness and density.

The 6061-T6 aluminum stairs have minimum yield strength of 35,000 psi (241 MPa) and a minimum ultimate strength of 42,000 psi (290 MPa).

Aluminum stairs are designed to be strong enough for some heavy-duty applications.

How Much Weight Can An Aluminum Stair Hold?

Standard aluminum stairs can carry a weight that ranges from 1000 lbs to 1500 lbs.

Other types of aluminum stairs carry less or more weight depending on the application it was designed for.

Aluminum stairs are designed to carry heavy weights without bending or breaking.

You should only purchase aluminum stairs from reputable suppliers to ensure the acceptable load rating of the stairs is correct.

Never put more weight on the aluminum stairs than it can actually carry.

Are Aluminum Stairs Rust Proof?

Aluminum stairs do not naturally rust because aluminum does not contain iron in its alloy.

Iron is the primary cause of the typical rust we know.

Aluminum stairs may corrode, but they are very resistant to corrosion because of the oxide layer formed on the surface of the aluminum when it comes in contact with air.

You can also apply paint or a powder coat to the aluminum surface to protect it from corrosion and rust.

Which Is Better Steel Ladder Or Aluminum Stairs?

Aluminum stairs and steel stairs are suitable for various applications. But you may need to pick between aluminum or steel, depending on your specific application.

Aluminum stairs are lighter than steel stairs, making aluminum stairs easier to ship and easier to install and uninstall.

But steel stairs are stronger than aluminum stairs, making steel suitable for permanent and heavy-duty applications.

Aluminum is more flexible and malleable than steel, making aluminum suitable for stair applications that require bending, such as spiral stairs.

Aluminum stairs are suitable for outdoor applications because aluminum is naturally resistant to rust and corrosion.

In contrast, steel usually contains iron which is the main cause of rust. If you plan to use steel outdoors, you must protect your steel stair from rust by using galvanizing coats.

Do Aluminum Stairs Expire?

Aluminum stairs will not expire if you take proper care of them. Aluminum is a material that can last a lifetime with little maintenance.

In fact, your aluminum stairs can last over 50 years with very little maintenance.

Aluminum stairs are also rust and corrosion-resistant. This means aluminum stairs can last a very long time without severe damage due to rust or corrosion that can ruin your stairs.

You can also protect your aluminum stairs from corrosion or rust by using paint or powder coating to prevent damage to the surface of the stairs.

Aluminum stairs will last for much longer than wooden stairs, making them better and cheaper in the long run.
