Install Aluminum Decking

Aluminum decking is becoming a popular choice for homeowners looking to enhance their outdoor spaces. With its durability and low maintenance requirements, it offers a long-lasting solution that can withstand the elements. You’ll love how it resists rust and decay, making it an ideal option for decks that see heavy use.

When considering installation, it's essential to factor in costs. While the initial investment for aluminum decking can be higher than traditional wood, the long-term savings on maintenance and repairs can make it a smart financial choice. In this guide, you'll discover the steps to install aluminum decking, ensuring you create a stunning and functional outdoor area without breaking the bank.

Overview of Aluminum Decking

Aluminum decking offers several advantages for outdoor spaces. This material provides exceptional durability, making it ideal for high-traffic areas. Aluminum resists rust and decay, ensuring long-lasting performance without the upkeep associated with traditional wood. Homeowners appreciate this benefit, especially when considering the time and costs related to maintenance.

The installation process of aluminum decking involves specific steps and considerations. Preparation begins with the substructure, which requires laying aluminum bearers on top of steel cradles or pedestals. Maintaining a 10 mm expansion gap between the ends of the bearers is crucial. Additionally, double bearers should be used at butt joints with approximately 6 mm spacing to ensure stability.

Once the bearers are secured to the steel pedestals using suitable screws, such as Tek screws, you can proceed with installing the deck boards. The first board is secured with starter fasteners, placed on every joist and aligned at the ends of the bearers. For subsequent boards, hidden fasteners, typically measuring 6 mm or 3 mm, should be inserted into the groove of the fixed board. It's essential to place one fastener per board end and to avoid sharing fasteners across two board ends, which enhances the stability and appearance of the deck.

Choosing aluminum decking leads to an aesthetically pleasing and functional outdoor area that combines style with minimal maintenance.

Benefits of Aluminum Decking

Aluminum decking provides numerous advantages that enhance outdoor spaces. Its unique properties contribute to a robust and visually appealing environment.

Durability and Longevity

Aluminum’s inherent strength ensures your decking withstands harsh weather conditions. This material resists rust, rot, and insect damage, making it ideal for high-traffic areas. Many aluminum decking manufacturers offer warranties of 20 years or more, reflecting confidence in its long-lasting performance. Choosing aluminum helps you avoid frequent repairs or replacements, ensuring your investment remains intact over time.

Low Maintenance Requirements

Aluminum decking requires minimal upkeep, saving you time and effort. Unlike wood, aluminum doesn’t need staining, sanding, or sealing. Simple cleaning with soap and water retains its appearance. The non-porous surface resists mold and mildew growth, reducing the need for chemical treatments. Additionally, aluminum's durability means it retains its color and finish, avoiding the fading that often occurs with other materials. Enjoy a beautiful deck without the hassle of extensive maintenance.

Installation Process of Aluminum Decking

The installation process for aluminum decking involves careful planning and execution. Following the outlined steps ensures a successful setup that maximizes durability and performance.

Preparation and Planning

Before starting the installation, solid preparation is essential for optimal results:

• Substructure: Confirm the substructure's stability, including steel cradles and pedestals. Aluminum bearers will rest on these components to ensure strength and support.
• Measurements: Measure the installation area accurately to determine the quantity of decking boards and bearers necessary. Account for expansion gaps of at least 1/8 inch between bearers to prevent buckling from temperature changes.
• Safety: Equip yourself with appropriate safety gear, including gloves and safety glasses, to protect against sharp edges and debris during installation.

Tools and Materials Needed

Gathering the right tools and materials ahead of time streamlines the process:

• Tools: Include essential tools like a circular saw, drill, measuring tape, square, and level. These instruments help ensure precise cuts and alignments.
• Materials: Include aluminum bearers, decking boards, fasteners, and connectors. Using high-quality materials enhances the decking's longevity and stability.
• Fasteners: Use starter fasteners and hidden fasteners for secure installation and a clean appearance.

Step-by-Step Installation Guide

Follow this systematic approach for effective installation:

1. Lay the Bearers: Position the aluminum bearers on the steel cradles or pedestals. Ensure they are leveled and spaced correctly to accommodate the decking boards.
2. Secure the Bearers: Attach bearers using appropriate fasteners. Confirm they’re securely fixed to the cradles to prevent any shifts during use.
3. Install the Decking Boards: Start at one end and lay the decking boards perpendicular to the bearers. Leave the necessary expansion gaps.
4. Cut Boards as Needed: Measure and cut individual decking boards to fit around edges or obstacles, ensuring a neat finish.
5. Fasten the Boards: Use starter fasteners at the ends and hidden fasteners along the length to ensure boards are securely attached to the bearers without visible screws.
6. Final Checks: Inspect your work for any loose boards or misalignments. Make necessary adjustments before considering the installation complete.

Executing these steps ensures you achieve a high-quality, aesthetically pleasing aluminum deck that requires minimal maintenance while enhancing your outdoor space.

Common Mistakes to Avoid

Avoiding common mistakes during the installation of aluminum decking is crucial for ensuring durability and safety. Pay close attention to the following key areas.

Inadequate Preparation

• Lay the bearers correctly. Place aluminum bearers on top of steel cradles or pedestals, maintaining a 10 mm expansion gap between the ends. Double up on bearers at butt joints to support deck board ends, ensuring about a 6 mm spacing between bearers.
• Align the substructure properly. Confirm that the bearers are level and securely fixed to the steel pedestals using appropriate screws, such as Tek screws for Hyperion decking.
• Align the deck boards accurately. Prior to installation, check that the deck boards align properly with the bearers. Secure the first board using starter fasteners installed on every joist to avoid shifting during use.

• Use the right starter fasteners. Secure the first decking board with starter fasteners to prevent movement and ensure a solid foundation for subsequent boards. This not only stabilizes the installation but also contributes to a polished final appearance.
• Avoid over-tightening fasteners. Over-tightening can damage the board or inhibit movement, leading to warping or gaps over time. Ensure fasteners are snug but not overly tight to allow for natural expansion and contraction of the materials.

By focusing on these aspects, you enhance the longevity and safety of your aluminum decking installation.

Conclusion

Investing in aluminum decking transforms your outdoor space into a stylish and functional area. With its impressive durability and minimal maintenance needs you can enjoy your deck without the constant worry of repairs. Following the installation guidelines ensures a long-lasting result that stands up to the elements.

By avoiding common installation mistakes you enhance the safety and longevity of your deck. The right preparation and execution make all the difference in achieving a beautiful finish. With aluminum decking you’re not just enhancing your home’s exterior but also making a smart financial choice for years to come.
