5 Best Outdoor Metal Stair Railing Kits

But it won’t serve its purpose if you use low-quality railings. Besides getting damaged with constant exposure to the sun and rain, cheap railings might even degrade the entire look of your house.

Fret not, because we have already searched the market to present you the best of the lot. So, here are five popular metal stair railing kits that you can DIY in a jiffy!

Buying Guide

Best Outdoor Metal Stair Railing Kits

Although knowing the best products on the market helps, you are only halfway through the journey of settling on the perfect metal stair railing kit for your space. The final choice must satisfy your preferences and requirements, rather than being just another popular product.

However, we understand that you are still confused about what to look for in a railing kit, especially if you are a beginner. That’s what this section will help you with.

Remember that not every stair railing kit serves the same purpose. For instance, if you have older family members or naughty kids in the vicinity, a rigid handrail will be your topmost priority. However, for others, the look of the railing may be more important.

Or, if you live in a rainy region, you might want a completely weatherproof option. Alternatively, users who are not very handy would want an easy-to-install product.

Hence, keeping in mind the varied needs of the users, we have compiled some crucial factors that you must consider before buying an outdoor metal stair railing kit.

1. Building Codes

You must check that the railing complies with the building codes of your region. For instance, according to the Occupational Safety and Health Administration (OSHA), handrails must withstand a 200-pound load, and the shape should be easy to grasp.

Moreover, the Accessibility Guidelines and Standards mandate a clearance of 1.5 inches between the handrail and the wall. Notably, most brands adhere to the International Building Code, the International Residential Code, and the American Disabilities Act, which ensure public safety and accessibility.

2. Number Of Steps

It’s never a case of “one size fits all” when it comes to stair railings, so ensure that you check the number of steps and the measurements of the area. The last thing you would want is to end up with a handrail that does not match your stairs.

Even among the railing kits above, we have mentioned suitable products for staircases with three to five steps. Some of the brands offer different sizes, too, so don’t forget to check them out.

3. Stair Risers

A stair riser is the vertical (sometimes inclined) element between one step and the other. Note that the measurement of the riser determines the height of the finished tread (the horizontal component on top of a step). And you will require both of these measurements to determine the ideal dimensions of a handrail.

4. Steps Materials

The material of the steps plays a crucial role in determining the right railing kit. The different types of materials include concrete, brick, timber, cast iron, steel, etc. Accordingly, you must choose a railing kit of suitable material.

Usually, stainless steel railings work with most materials. Galvanized steel is another popular pick as it prevents corrosion. Similarly, a wrought iron handrail should feature a powder coating to make it rust-proof.

5. Handrail Design

With so many designs to choose from, picking the perfect handrail for your porch can become a daunting task. But besides your preferred aesthetic, we suggest opting for a handrail design that best serves the purpose.

For instance, a stair railing with an attached gate is a must if you have kids and pets. This prevents them from stepping outside the vicinity and keeps them safe.

If you do not have a deck or a porch, a brick wall handrail right outside your door would be a suitable option. Such a handrail design connects the floor at the bottom of the steps with the wall of the house.

6. Handrail Colors

The material largely determines the handrail color unless you paint it by yourself later. However, plastic is the most versatile material if you want a pop of color in your exteriors.

Additionally, wooden handrails are perfect to create a vintage and timeless vibe in your deck. But, as you may have guessed, you will be stuck with shades of brown and cream. Thankfully, warm tones complement many colors and styles, so there’s nothing to worry about in that aspect. We recommend oak for a lighter hue and mahogany if you want a deeper brown.

Aluminum is another popular choice of material for handrails. It is cheap, durable, and usually available in black and white color. Similarly, with iron, you get a limited color palette of these two shades, and maybe some shades of grey and silver.

7. Kit Components

While buying a DIY kit, always ensure that it includes all the necessary tools and accessories. This saves you from the time and extra expense of getting such hardware later.

Typically, a stair railing kit should include the deco rail and mid-rail, posts (number may vary according to the design), binding bolts, fasteners, and a base trim. Additionally, opt for a product that includes an installation guide with clear instructions, preferably with illustrations.

How to Install an Outdoor Metal Stair Railing?

What’s the use of a DIY railing kit if you don’t know how to put it up? Absolutely nothing!

But fret not because we’ve got you covered with some simple steps to install your handrail in a jiffy. So, whether you want to replace an old railing or install one on a new deck, this method will ensure optimum safety with style. And let’s not forget the installation charges that you will be saving!

Step 1- Measuring The Steps

Considering how important accurate measurements are, not a lot of people are careful at this stage. So, make sure you measure the depth of the landing, the landing slope, the total “run,” and the total “rise.”

The “run” of the staircase is the distance between the top portion of the highest step to that of the lowest step. Similarly, the “rise” refers to the height from the top of the bottommost step to that of the highest step.

You can purchase a suitable railing kit or place your order with a railing fabricator according to these measurements.

Step 2- Position The Handrail

Once you get the ideal handrail for your steps, start by positioning it on the desired area without the post mounts. Check if any of the posts require slight trimming to fit the staircase. In most cases, the railing either leans forward or backward.

Raise the post that is leaning away from the steps and keep the opposing post straight on the ground (coinciding with the plumb). Then, measure the distance from the bottom of the post to the ground to determine the trim-off dimension. This is the amount you must cut from the opposing post to ensure the perfect fit.

Now, pre-drill a hole on each end and use anchors to secure the railing temporarily. Thereafter, you can mark holes for the rest of the posts. We recommend drilling ½-inch holes for marking. Then you can set the railing aside and deepen the holes by two more inches.

Follow it up by tapping in the anchors and fastening the handrail with nuts. But don’t fully tighten them until the next step.

Step 3- Plumb For Perfection

Now, use a level to ensure that the posts are perfectly perpendicular to the ground. If you spot a leaning post, loosen the nuts and straighten it with a washer. Repeat until all the posts are straight.

Additionally, you can use a mini hacksaw to remove the hex nuts and replace them with matching cap nuts. Note that this is just an optional step.

You must also ensure that you wear safety gloves throughout the process. No matter how handy you are, you can never be sure with sharp equipment. Children and pets should stay away from the work area, and you must never leave your tools unattended. After all, it is better to stay safe than sorry.


How do I measure my steps?

Start by measuring the overall height, i.e., the distance from the landing of the lowest step to that of the highest step. Then, determine the overall horizontal length by measuring the distance from the edge of the nose of the first to the last step.

Further, the length of the nosing will determine the length of the top deco of the handrail. For this, you will have to measure the slanting distance between the edge (nose) of the first to the last step.

Also, you will require the depth and height of the tread. For this, simply measure the length and height of a step.

Interestingly, tons of websites offer staircase calculators, so you can use one of those to ensure more accuracy.

Do I need a handrail for two steps?

The International Building Code recommends having a handrail for a staircase with two or more risers, but it largely depends on your requirements. If your area is prone to rain and snow, even climbing those two steps without support can become a challenge, especially for older adults.
However, if you do not have any elders or kids in the house, you don’t need a handrail for two steps.

Do I need a 4 ft or 5 ft railing for 4 steps?

sually, handrails for four steps measure about 4 ft. However, we still recommend measuring the area and purchasing accordingly instead of assuming the ideal dimensions.

How high should a handrail be on outside steps?

According to the ICC Handrail Codes and the ADA-Compliant Handrail Height, the height of a handrail should be between 34-38 inches above the steps.

Are handrails required on both sides of exterior stairs?

Although we suggest having handrails on both sides for more safety and support, staircases with a width less than 44 inches can have just one railing. Moreover, staircases with less than four steps need not have a railing at all.

However, this too depends on your personal preference and requirements. If your family consists of senior citizens, children, and specially-abled people, consider getting railings on both sides of the stairs.

How much does it cost to install railing on front steps?

On average, if you do not opt for DIY railing kits, installing a handrail on the front steps can cost $900. The cheapest deals can range from $500 to $700. On the other hand, if you opt for high-end materials, you may have to shell out more than $10,000.

Note that these prices are subject to change according to your location, the kind of railing you choose, the material of the steps, and more.


With that, we come to the end of this comprehensive review-based guide. Besides introducing you to the best outdoor metal railing kits on the market, we hope we’ve clarified your doubts regarding the installation process, cost of installation, and more.

We tried to consider different preferences and requirements, and suggested these products accordingly. However, if you feel the need to find one for yourself, we recommend going through the buyer’s guide to know the factors that make one product different from the other.

Lastly, here’s a tip before we sign off- always consider the requirements of your family members while shopping for hand railings. While a particular product may look fancy, it may not be sturdy enough, which kills the purpose of having a handrail.
