Aluminum or Steel Pergola Specs
Frame Material
The MIRADOR 111S Takasho uses a full aluminum frame with steel components, creating a hybrid structure. This combination aims for durability while reducing overall weight. In contrast, the Breezestival leans heavily on carbon steel for its columns and triangular supports, paired with an aluminum frame. Steel provides high tensile strength and rigidity. The Breezestival highlights anti-rust finishes and reinforced triangular supports to handle heavy loads. You get different structural behaviors: the aluminum-heavy MIRADOR may resist corrosion differently than the steel-dominant Breezestival. Both designs prioritize long-term stability, but the material mix changes how each unit feels and performs under stress.
Roof Style
Roof functionality defines the user experience for both structures. The MIRADOR 111S Takasho features a bioclimatic louvered roof made of aluminum. You can adjust these louvers from 0° to 93° using a crank system. This allows you to control sunlight, ventilation, and shade precisely. The Breezestival offers a fixed sloped roof made of polycarbonate panels. It relies on an inclined design with gap drainage for water runoff. You cannot adjust the angle of the Breezestival roof. The MIRADOR provides active climate control, while the Breezestival offers passive, consistent coverage. Your choice depends on whether you want dynamic shade or simple, reliable protection from rain.
Roof Material
The materials covering your head differ significantly between these two options. The MIRADOR 111S Takasho uses aluminum for its roof, matching its frame components. Aluminum is lightweight and naturally resistant to rust, maintaining its finish over time. The Breezestival utilizes 5mm polycarbonate hardtop panels. Polycarbonate is known for impact resistance and UV reflection, blocking up to 99% of harmful rays. It allows natural light to filter through while providing shade. Aluminum offers a solid, opaque barrier, whereas polycarbonate creates a diffused lighting effect. If you prefer natural light, the polycarbonate is ideal. If you want complete shade and a traditional look, the aluminum louvered roof is the better fit.
Size
Coverage area varies based on your space requirements. The MIRADOR 111S Takasho is sized at 10 feet by 13 feet. This creates a compact, intimate shade area suitable for smaller patios or decks. The Breezestival is significantly larger, measuring 10 feet by 20 feet. This provides 175 square feet of shaded space, accommodating up to 10 people comfortably. The Breezestival is a lean-to design, meaning it attaches to a wall, which affects how you measure your installation space. The MIRADOR is a freestanding structure. You must choose between the compact footprint of the MIRADOR and the expansive coverage of the Breezestival based on your available patio dimensions.
Included Features
Some accessories come standard with one unit but not the other. The Breezestival includes an outdoor string light set with 15 sockets and 16 shatterproof bulbs. These LEDs have an IP65 waterproof rating, allowing you to create ambiance immediately after assembly. The MIRADOR 111S Takasho does not list any included lighting or electrical features in its specifications. You would need to source lighting separately for the MIRADOR. If you want a ready-to-use entertainment space with integrated lighting, the Breezestival offers this convenience out of the box. The MIRADOR focuses purely on the structural elements, leaving aesthetic additions to your discretion.
Weight
The physical mass of the structure impacts assembly and stability. The MIRADOR 111S Takasho weighs 462 pounds. This substantial weight helps anchor the freestanding unit against wind. The Breezestival does not list a total weight in its specifications. However, it is a lean-to design that mounts to a wall and ground. This mounting method distributes the load differently than a freestanding frame. The MIRADOR relies on its mass and footprint for stability. The Breezestival relies on its wall attachment and reinforced triangular supports. You need to verify the weight capacity of your wall for the Breezestival, while the MIRADOR requires a solid, level ground surface to support its 462-pound frame.
Which pergola matches your needs
You want adjustable shade and ventilation
The MIRADOR 111S Takasho features a louvered roof with adjustable louvers ranging from 0° to 93°. This crank system lets you control sunlight and airflow precisely. Its aluminum and steel frame supports this moving mechanism while resisting rot. You get personalized climate management for your patio without needing a solid roof.
You need heavy snow and wind resistance
The Breezestival pergola is built with carbon steel columns and a triangular structure for stability. It withstands winds up to 70 mph and handles snow loads of 55 lbs/㎡. The sloped polycarbonate roof ensures water runoff. This steel-heavy design offers robust protection against harsh weather conditions for your outdoor space.
You want included lighting and large shade
This model includes an outdoor string light set with 15 sockets and shatterproof bulbs. It provides 175 square feet of shade under its 10' x 20' footprint. The polycarbonate hardtop blocks 99% of UV rays while letting light through. You get a complete entertainment setup with integrated lighting for evening gatherings.
You prefer a wood-like aesthetic
The MIRADOR 111S Takasho offers a Takasho wood grain finish on its aluminum frame. This look replicates natural wood without the risk of rot or discoloration. The clean lines and hidden fixings create a modern appearance. You achieve the warmth of wood with the low maintenance benefits of aluminum construction for your deck.

Frequently asked questions
Does aluminum frame rust like steel?
Aluminum naturally resists rust, making it a low-maintenance choice for outdoor structures. The MIRADOR 111S Takasho uses an aluminum frame that helps prevent corrosion over time. Steel frames, like the Breezestival model, are often coated to resist rust but may require more vigilance to maintain their finish in wet conditions.
Which frame is lighter to move?
Aluminum frames are significantly lighter than steel alternatives. The MIRADOR 111S Takasho weighs 462 pounds, offering a manageable weight for its size. Steel structures like the Breezestival 10x20 Lean-to Gazebo do not list a weight, but steel is generally denser. You will find aluminum easier to handle during installation or relocation.
Can I adjust the roof on a steel pergola?
Adjustability depends on the design, not just the material. The aluminum MIRADOR 111S Takasho features a louvered roof with manual crank control for adjusting airflow and light. The steel Breezestival model has a fixed polycarbonate hardtop. You cannot adjust the roof angle on the steel unit once installed.
Is steel stronger than aluminum?
Steel generally offers higher tensile strength than aluminum. The Breezestival uses carbon steel columns for its structure, providing a rigid and heavy-duty frame. Aluminum, used in the MIRADOR model, is lighter but still durable. You get maximum structural rigidity with steel, while aluminum provides strength with reduced overall weight.
Do these pergolas fit against a wall?
The Breezestival 10x20 Lean-to Gazebo is designed as a lean-to structure, requiring a wall for support. Its 234-inch length makes it ideal for attaching to a home. The MIRADOR 111S Takasho is a freestanding unit with a 120-inch width and length. It does not require a wall for stability.
What roof material comes with these options?
The aluminum MIRADOR 111S Takasho uses a louvered roof system made of aluminum slats. The steel Breezestival model includes a polycarbonate hardtop roof. Polycarbonate provides durable, translucent shade. The aluminum louvers allow you to open or close the roof manually. Each material offers different light and weather protection.
How tall are these structures?
Both units offer similar overhead clearance. The MIRADOR 111S Takasho stands 98.4 inches tall. The Breezestival 10x20 Lean-to Gazebo also measures 98.4 inches in height. This standard height allows most adults to walk under them comfortably. You should verify your local clearance requirements before installation.
Can I add lighting to the frame?
The Breezestival 10x20 Lean-to Gazebo includes built-in LED lights. These are integrated into the steel frame structure for convenient evening use. The MIRADOR 111S Takasho data does not mention included lighting. You may need to add separate lighting fixtures if you choose the aluminum model for nighttime ambiance.
