Home Construction 101: The Beginner’s Guide to Deck Railing

Having your own home is enjoyable because you can do as you please with it, such as installing various home improvements. There are many examples of home improvements, but one that’s particularly great for bigger homes is a deck railing.

A deck railing is a necessary addition to most homes with decks. It’s meant to protect those using the deck from falling, and it also makes the deck look much more attractive. Additionally, it may earn your house more value and be eligible for a deduction. If you’re thinking about getting a deck railing, we’re here to help.

This article will discuss everything there is to know about deck railings. Read on below to get started.

Components of a Deck Railing

A deck railing may look simple, but it comprises various parts that make it whole. These are:


Also known as the top railing or handrail, the railing is used to help prevent people from falling off the deck. It’s typically a horizontal bar that runs along the outer edges of the deck. Manufacturers create it in different materials, including wood, metal, and composite.

Bottom Rail

The bottom rail is like a continuation of the top railing. It has the same function to help prevent people from falling off the deck. It’s usually shorter than the top railing, though, and it can also be thinner. It’s also installed lower to the ground because it acts as the foundation.

Vertical Supports

More commonly known as posts, vertical supports are installed at the corners of the deck where the top and bottom railing meet. They’re typically made of wood and should be attached firmly to a concrete foundation. They help support the weight of the top and bottom railings and make them stable.


These are also known as infills. Balusters are vertical posts that prevent the railing from moving, and they’re helpful because they allow people to walk up and down the deck without the top and bottom railings interfering with them. This will be especially important when snow becomes wet and heavy during the winter months.

Post Caps

These are decorative caps that are placed at the top of the posts. They’re meant to cover the top, make the posts look more attractive, and protect the posts from getting dirty.

Types of Deck Railing Systems

Since deck railings are available in various styles, they can fit in most homes. Examples include:

Aluminum Railing

An aluminum railing is a good choice for those who want an affordable railing. Aluminum is durable and lightweight, making it perfect for those who wish for a railing that looks nice but isn’t too heavy.

Steel Deck Railing

Steel railing is another affordable option, but with a more industrial look. It’s very similar to aluminum railing except that it’s heavier and it may draw more attention. It’s not recommended for use on decks that have views.

Composite Deck Railing

Composite railing is similar to wood, but it’s safer and more durable. It’s an excellent deck railing option, especially for locations subjected to heavy exposure to the elements.

Cellular PVC Deck Railing

This is an excellent choice for anyone who wants a low-maintenance railing. Made of PVC plastic, cellular PVC is less likely to crack or splinter, making it a durable option for deck railings.

Vinyl Deck Railing

Made from PVC plastic, vinyl decks are easy to install and withstand extreme weather. They’re also cost-effective and can be painted to fit your house’s exterior design.

What Should You Get?

Deciding on the style of deck railing for your home will depend on factors such as your personal preference and the environment where it will be installed. Choose one that fits your style and location, and you won’t regret it. These railings are easy to maintain and can last for many years to come, so don’t hold back on getting one that you think will be the best fit for your deck.
