Shade, Beauty, and Outdoor Relaxation

Pergolas, like decks, are loved by those who want to extend their outdoor living space. Pergolas make a great project because they can be built from a variety of materials and can be designed to fit almost any space. The most common material is wood, but vinyl or fiberglass kits are available. Pergolas are popular because they offer a wide range of benefits. They can be built with common materials like pressure treated lumber or cedar, and their designs can be as simple or as complex as you want it to be, making it an approachable project for the weekend warrior. A pergola will add style and value to any outdoor living space. Orientated correctly and built with a shade style top, it provides a welcomed shady spot on those hot sunny days. While not required, the addition of decorative brackets and some string lights transform a pergola into an entertainment focal point for your next gathering.

Building a Pergola

Options exists to buy a custom pergola kit, but a typical pergola can be made from standard wood and building materials found at your local home centers. Pergolas are generally composed of four corner columns that are used to support a cross beam open roof system. The shift away from conventional standard zinc color lag bolts toward decorative structural screws has been a good trend for pergola builders. Black hex headed decorative structural lags are commonly used in connecting the columns and beams, offering a nice, inexpensive, and decorative touch to wood pergola projects. Build your pergola with confidence knowing that SPAX® structural lags are third-party tested, and our High Corrosion Resistance (HCR®) coating will last as long as your project!

Things to Consider when Building a Pergola

Planning and Design

Choose a suitable location for the pergola based on the client's preferences and the layout of the outdoor space. Check local regulations to determine if any permits or approvals are required before construction. Collaborate with the client to develop a design that meets their needs and fits the overall aesthetic of the space.

Gather Materials and Tools

Measure the area and determine the required quantity of lumber, hardware, and other materials for the project. Purchase high-quality lumber, preferably treated for outdoor use, along with necessary hardware, concrete, and any additional features or accessories. SPAX has the right specialty fasteners for this job! Ensure you have the necessary tools, such as a circular saw, drill, impact driver, level, tape measure, post hole digger, hammer, and safety equipment.

Site Preparation

Use stakes and string to mark the perimeter and layout of the pergola. Remove any vegetation, rocks, or debris from the site, ensuring a clean and level surface.

Post Installation

Use a post hole digger to create holes for the pergola's support posts, following local building codes for depth and spacing. Place the posts in the holes and secure them with concrete or gravel, ensuring they are level and plumb. Allow the concrete to cure according to the manufacturer's instructions.

Beam and Rafters Installation

Attach the horizontal beams to the support posts, ensuring they are level and securely fastened. Attach the diagonal or vertical rafters to the beams, evenly spacing them and securing them in place. Use a level to ensure proper alignment.

Optional Features

Install lattice panels, shade cloth, or other decorative elements as per the client's specifications. If the client desires lighting or fans, plan and install the necessary electrical wiring before finishing the pergola.

Finishing Touches

Smooth any rough edges using sandpaper and apply a protective finish or stain to the pergola for longevity and aesthetics. Ensure the structure is stable and secure by conducting a thorough inspection and making any necessary adjustments.

Remember, every pergola project is unique, and specific details and techniques may vary based on the design and client preferences. It's important to consult local building codes and regulations, as well as adapt the construction process to suit the specific project requirements.

Double Barrier Coating with PowerLags

Our Double Barrier Coating

Our HCR® (High Corrosion Resistance) double-barrier coatings offer superior protection with a double barrier. First plated with a zinc base coat and finished with a durable top coat, they’re engineered to hold up to the harshest conditions. Tested and recognized for use in ground contact pressure treated lumber for exterior, freshwater general construction applications (e.g., AWPA UC1-UC4A, UCFA).


Some competitors don’t actually test their coatings. They rely on data from their paint company before it makes it onto their screws.
