Wholesale 220 Specification Aluminum Louvered Pergola For Pool Decks And Coastal Terraces Manufacturer, Suppliers
Product Description
Engineering Standard
Extrusion Geometry and Metallurgy Specifications
The structural performance and deflection resistance of the overhead assembly under environmental loads are determined by the cross-sectional geometry and temper designation of the aluminum components. All framing members are formed through industrial extrusion using a structural aluminum alloy, which undergoes thermal solution heat treatment and artificial aging to achieve a T6 temper profile.
Overhead Roof Louvers
The individual blades feature an outer width of 220mm and a thickness of 55mm. The extrusion has a continuous wall thickness of 2.0mm. The cross-section utilizes a dual-wall hollow profile integrated with a longitudinal center reinforcing rib that prevents profile warping or twisting under sustained solar heat or wind pressure.
Perimeter Header Beams
The horizontal framing beams measure 280mm in vertical height by 46.8mm in width, with an engineered wall profile thickness of 2.5mm. The tall vertical dimension creates a high section modulus to handle vertical loads across single-bay spans without mid-span supports.
Aerodynamics & Ventilation
Climate Control Kinematics
The overhead roof functions via a manual mechanical linkage or an internal automated linear drive system that rotates the 220mm wide louver blades through a defined 90-degree operating arc.
Convective Cooling Principles
When the louvers are turned to an intermediate 45-degree angle, the blade orientation blocks direct vertical solar rays from reaching the patio floor while leaving open vents between the profiles. This layout allows warm air under the structure to rise naturally out of the roof, drawing cooler ambient air in from the sides. Turning the blades to a complete 90-degree vertical orientation allows maximum daylight penetration into the lounge area during early morning hours.
Certified Durability
Structural Engineering Certifications and Verified Loads
The structural integrity of the 220-specification framework has been calculated and verified through physical testing to meet local building code regulations for permanent exterior structures.
120 mph Sustained Wind Load Certificate
The structural combination of 2.5mm profile wall thicknesses, internal steel corner reinforcement brackets, and solid base anchoring allows the structure to withstand sustained lateral wind forces up to 120 mph. This certified rating makes the framework suitable for open beachfront properties, exposed valley locations, and high-rise commercial rooftops.
160kg/㎡ Static Snow Load Rating
The reinforced dual-wall louver profiles and thick-walled 280mm main beams are rated to carry up to 160kg/㎡ of static downward weight when the louvers are fully closed. The aluminum frame holds this load without permanent bending or structural deflection, allowing the structure to remain fully closed through winter weather to protect patio spaces.

Frequently Asked Questions
What are the structural dimensions of the 220 Model components?
The system features roof louver blades measuring 220x55x2.0mm, perimeter header beams measuring 280x46.8x2.5mm, and primary support columns sized at 180x180x2.5mm.
What wind velocity can this louvered pergola withstand?
The framework is certified for sustained wind forces of up to 120 mph, thanks to 2.5mm profile wall thicknesses, internal steel corner reinforcement brackets, and heavy-duty base anchoring.
How much snow load capacity does the roof structure support?
When the dual-wall louvers are fully closed, the structure provides a verified static snow load rating of up to 160kg/㎡ without permanent bending or structural deflection.
How does the louvers' kinematics system provide cooling?
Adjusting louvers to an intermediate 45° angle deflects direct sunlight while creating venting gaps. This induces natural convection that vents trapped hot air upwards while pulling cooler ambient air through the sides.
What alloy and protective surface finishes are used?
All members are formed via industrial extrusion using architectural structural aluminum alloy heat-treated to a T6 temper, then protected with high-density powder spraying for long-term outdoor weather resistance.
Can the dimensions of the pergola system be customized?
Yes, dimensions are customizable to match bespoke patio layouts, commercial poolside configurations, and rooftop projects.
