What is a Radius Joist Cantilever Pergola?
A radius joist cantilever pergola is a modern steel shade structure engineered to provide overhead coverage while maintaining an open, unobstructed layout beneath. The radius joists are curved structural members that create a smooth architectural profile while helping distribute weight evenly for strength and stability.
The cantilever design allows the pergola to extend beyond its main support posts without additional columns at the outer edge. This creates more usable space below, improves movement through the area, and keeps sightlines open, making it ideal for patios, outdoor kitchens, poolside spaces, and commercial seating areas.
Because the structure is built from steel, it offers greater durability than traditional wood pergolas. Steel resists warping, insect damage, and moisture related deterioration, making it a reliable long term shade solution.

Why Choose Our Radius Joist Cantilever Pergolas
Engineered Strength Meets Design
Our pergolas are built from high quality structural steel, giving them exceptional strength, stability, and lifespan compared to traditional wood systems. Steel resists warping, cracking, insect damage, and moisture related deterioration, which are common failure points in outdoor structures. This means your pergola maintains its structural integrity and clean appearance with far less maintenance over time. The result is a shade solution that performs reliably while supporting modern architectural design.
Architectural Impact With Open Space
The cantilever design allows the pergola to project outward beyond its main support posts, eliminating the need for columns at the outer edge. This keeps the area underneath open and flexible, making it easier to arrange furniture, maintain clear sightlines, and move freely through the space. Visually, the extended roofline and curved joists create a striking architectural feature that adds depth, dimension, and contemporary character to residential and commercial properties.
Custom Built for Your Vision
Every pergola is designed to match your specific layout, usage needs, and style preferences. Whether the goal is to shade a patio, cover an outdoor kitchen, or define a commercial gathering area, dimensions, joist configuration, and finish options are selected to complement the surrounding architecture. This design flexibility ensures the pergola feels integrated rather than added on, enhancing both function and visual appeal.
Built for Long Term Outdoor Performance
Our pergolas are engineered to withstand prolonged sun exposure, rain, and seasonal weather changes without compromising strength or appearance. Protective coatings help defend against corrosion and surface wear, while precision fabrication ensures consistent performance across the structure. This focus on durability means your pergola continues to provide dependable shade and structural stability year after year with minimal upkeep.
