Why is a Metal Pergola Better than a Wood Pergola?

Pergolas are fabricated from an array of materials including wood, vinyl and metal. There are advantages and disadvantages to each material.

  • A wood pergola, for instance, requires extensive maintenance and consists of heavy material limiting where a larger pergola may be constructed.
  • Vinyl pergolas are lightweight and reduce maintenance needs; however, they are less durable than a wood or metal pergola.
  • Metal pergolas, on the other hand, are durable, lightweight, and minimize necessary maintenance. Let’s explore the unique advantages of a metal pergola.

What Metal Is Best for Pergolas?

The most prominent metals used in the fabrication of pergolas are steel and aluminum. Both are durable and strong metals. Aluminum is much lighter weight than steel, so it is the preferred fabrication material for today’s modern pergolas. Left untreated, both metals are susceptible to oxidation. Metal pergolas, then, usually receive a heavy-duty exterior coating to repel water. While some manufacturers rely on exterior paint, paint is prone to chipping over time, leaving exposed metal to rust.

Here at Azenco we build all of our outdoor living structures from high-quality aluminum and apply a high-quality powder coating for protection. We also customize powder coating to match any home’s exterior color scheme. We can even apply a wood grain to the roof of the structure for a wood feel.

What Are the Benefits of a Metal Pergola Frame?

The pergola frame is made up of support columns and the roof structure can be an adjustable louvered roof or made of insulated sandwich panels to create a fixed-roof pergola. A metal pergola frame is hollow to allow the space to be leveraged for numerous applications. In our pergola designs, we leverage this hidden space to house an integrated pergola gutter system that captures rainwater and channels it to downspouts at the base of the columns. This allows rainwater to be directed away from the patio, keeping the outdoor space dry during heavy rain showers.

What Differentiates a Metal Pergola Roof from Wood?

A wood pergola is limited in its functionality. The weight of a wooden pergola roof means it would be difficult to create adjustable lovers from the material, so wood pergolas are static structures. They can be designed with a solid shingled roof for full-time shade, or with static louvers to create some shade, but cannot block out sun and rain. On the other hand, fabricating the structure from lightweight aluminum allows the metal pergola with roof louvers to become adjustable. We incorporate whisper-quiet electric motors to open and close the louvers. This motorized control combined with precision manufacturing practices ensure that our louvered roof pergolas close tightly to create a gapless seal against rain or snow.


Why is a Metal Pergola Modern?

The greatest advantage of leveraging lightweight aluminum with a hollow frame design is we are able to integrate all kinds of comfort features into our custom designs. Our R-Blade adjustable louvered roof pergola can include a smart sensor array that monitors for rain, and that autonomously closes the roof at the first sign of showers. You can also add a wind sensor to monitor for high winds, and open the louvers to mitigate damage from powerful updrafts. A metal pergola can also hide other amenities in the frame, including motorized retractable privacy curtains or insect screens, LED lighting, infrared heaters, etc. Adding these types of accessories to a wooden pergola would leave wiring and receptacles exposed to view, but a metal pergola hides these components to maintain clean exterior lines.


What Projects Require a Metal Pergola Rather Than Wood?

Most pergola products, whether a standalone small metal pergola or a metal pergola attached to house, projects are built to create shade for a patio or pool deck and will have their footings buried in the ground. For these terrestrial projects, the overall weight of the structure does not make too much of a difference. A qualified engineer can design a wood or metal pergola to meet necessary structural regulations without worrying about the overall weight of the structure. But, for pergola projects on a deck, veranda, or roof deck, the overall weight of the structure becomes very important to the structural integrity of the deck, veranda, or roof. In these cases, a lightweight aluminum pergola is likely the only solution that will satisfy engineering and permitting codes.


Conclusion

A modern metal pergola is the ideal outdoor living structure and will bring a new level of enjoyment to a patio, deck, or roof deck. For homeowners and commercial property owners looking to create the most-advanced pergola with motorized functionality, embedded amenities, in a unique location, lightweight-but-strong aluminum is the material from which to choose.
