A pergola is essentially a backyard structure that provides shade and a sense of seclusion. It's often confused with a gazebo, but a pergola is typically more open and free-standing.
The main components of a pergola include the posts, beams, and rafters. Posts are the vertical columns that support the structure, while beams are the horizontal elements that connect the posts. Rafters are the sloping beams that make up the roof.
The type of wood used for the pergola's posts and beams can greatly impact its durability and aesthetic appeal. Some common options include cedar, pine, and pressure-treated wood.

Pergola Basics
A pergola is essentially a structure with a series of vertical posts that support a roof or other overhead feature.
You can build a pergola using a variety of materials, including wood, metal, and vinyl, as seen in the different types of pergolas discussed in the article.
The main components of a pergola include columns, beams, and rafters, which work together to provide support and create a sense of openness.
A pergola's columns can be made from a single piece of material or assembled from multiple pieces, as shown in the article's discussion on column types.
The beams that make up a pergola's roof can be horizontal or sloping, and are often used to create a sense of depth and visual interest.
A pergola's rafters are typically the smallest and most delicate of the three main components, and are often used to add a decorative touch to the structure.
The height and design of a pergola's columns, beams, and rafters can be adjusted to suit different architectural styles and purposes.
Planning and Preparation
Before you start planning your pergola, take the time to measure the space you have to work with. It's crucial to consider how much space you have available and whether you need to take any existing patios or structures into account.
A well-placed pergola can truly elevate your outdoor oasis, but it's essential to start with the right measurements to ensure a successful installation.
To ensure a successful pergola installation, it's recommended to follow nine site preparation tips.
Pergola Parts
A pergola is a beautiful addition to any outdoor space, but have you ever wondered what makes it up? Let's take a look at the main parts of a pergola.
The posts are the main vertical components of a pergola, providing the support for the structure. They're usually made of strong materials, like timber, and are guaranteed for a long period of time.
The type of posts you choose will depend on the size and design of your pergola. For example, a standard pergola post is 2.70m long and 91mm x 91mm wide.
Here are the common parts of a pergola:
- 2x8 Beams (2)
- 2x6 Notched Rafters (3-9 depending on size)
- 6x6 Posts (2 or 3 depending on size)
- 2x2 Top Slats
- Hardware
These parts can vary depending on the size and design of your pergola. For example, a full-size pergola kit may include 4 posts, 2 beams, and a varied number of rafters and top slats.

Parts of a Call
A pergola is a beautiful addition to any outdoor space, but it can be overwhelming to figure out what parts make it up. The main vertical component of any pergola is the posts, which provide the support for the structure.
Posts should be made of strong material that can withstand the elements and last for a long time. Our timber posts are guaranteed for 25 years and have been treated to ensure they are suitable for in-ground contact.
The posts are typically 2.70m long and 91mm x 91mm wide, and it's recommended to install them so that the underside of the side rails is 2m above ground level. This gives a good amount of clearance from ground level and allows for the posts to be 700mm in the ground to provide adequate support for the pergola.
Side rails are one of the main horizontal components of a pergola, forming the base for the cross members to sit on. They should be affixed to either side of the posts and supported by braces.
Here's a breakdown of the main parts of a pergola:
- Posts: provide the support for the structure
- Side rails: form the base for the cross members to sit on
- Cross members (or cross beams): sit across the width of the pergola and provide a recognisable rafter effect
- Spacer blocks: small pieces of timber installed between the side rails, roughly halfway between the posts, to maintain a consistent width between the side rails and cross members
These are the main parts that make up a pergola, and understanding them will help you build or purchase the perfect pergola for your outdoor space.

What Fixings Do I Need?
When choosing fixings for your pergola, it's essential to select high-quality options that will withstand the elements. Stainless steel screws or galvanised nails are recommended for their durability and resistance to rust.
Rusty nails can lose their integrity over time, causing the pergola's structure to weaken. This can be a costly and frustrating issue to deal with.
A good quality pergola fixing pack can simplify the installation process and ensure that your pergola looks its best for years to come.
Installation Steps
Installing your pergola is a straightforward process that requires some planning and elbow grease. To start, lay out the pergola pieces where you'd like to install the pergola.
First, lay one beam on the ground and position the posts on top of it, making sure they're aligned with the marks that say "post" on the Brim pergola kit. This will give you a solid foundation for the rest of the installation.
Next, lay the other beam on top of the posts, creating a sandwich with the two beams on the outside and the posts in the middle. This is where the structure of your pergola starts to take shape.
You'll need to insert the four 1/2" bolts with a washer on each through the predrilled holes that go through the beams and posts. Make sure they're securely in place before moving on to the next step.
Flip the assembly over by lifting the end of the posts up and over while the beam stays on the ground. This might take some effort, but it's an important part of the process.
Now, put another washer and a nut on each of the bolts and tighten them with a 3/4" wrench. Make sure they're snug, but don't overtighten them just yet.
Before you start digging, mark the ground for the center of the post holes. You'll want to dig holes that are at least 2' deep and approximately 12" in diameter.

Here's a quick rundown of the steps to follow:
- Lay out the pergola pieces.
- Lay one beam on the ground and position the posts on top of it.
- Lay the other beam on top of the posts.
- Insert the 1/2" bolts with a washer on each.
- Flip the assembly over.
- Put another washer and a nut on each bolt and tighten with a 3/4" wrench.
- Mark the ground for the center of the post holes.
- Dig the post holes.
Stand the assembly up and let the posts slide down into the holes. Have your helper hold each post plumb while you pour dry concrete into each hole. Don't water in the concrete yet – you'll want to let it dry first.
