●Balusters and pickets are traditional options that can range from simple to ornate.

Weight Load

●Choose railings rated for appropriate weight loads; 125 pounds per square foot in vertical pressure is standard, with 200 pounds for lateral force.
●For high-traffic or public areas, consider railings with higher weight capacity ratings.

Matching Décor

Installing Aluminum Railings

When it comes to installing your new aluminum railing system, you have two options – hiring a professional or opting for a DIY project.

Professional Installation

Experienced deck builders and railing installation pros can expertly handle the entire job from precise measuring to custom fabrication of posts and rails to finished mounting. This ensures correct building code compliance, safety, and aesthetically pleasing results. Hiring pros adds to the project cost but can provide peace of mind.

DIY Installation

Ambitious and skilled DIYers can tackle aluminum railing installations on their own. The process involves securing sturdy mounting hardware and brackets to your deck substructure, attaching bottom and top railing posts per the manufacturer’s instructions, inserting any infill panels or mesh, and then adding decorative post caps. Precision measuring is key, as is drilling accurate pilot holes before fastening.

Most reputable aluminum railing companies provide detailed installation manuals and instructional videos. Some even offer Zoom or over-the-phone guidance. Budget plenty of time and patience – complex railings with curves, angles, and glass panels prove especially tricky for amateur installers.Inspect your new railings to ensure a sound, wobble-free structure that meets local safety codes. Most building codes require professional inspection, especially for second-story and non-ground-level decks.

Q1: Are aluminum deck railings expensive?

A: Aluminum deck railings are considered a mid-range option when it comes to cost. They are generally more affordable than wrought iron or steel and can be less expensive in the long term compared to wood, due to lower maintenance costs. While they may have a higher upfront price than some materials like vinyl, their durability, and longevity can make them a cost-effective choice over time.

Q2: How long do aluminum deck railings last?

A: Aluminum deck railings are known for their long-lasting qualities, often outlasting the decks to which they are attached. With proper installation and minimal maintenance, they can last for decades. Their resistance to rust, corrosion, and weather-related damage contributes significantly to their lifespan.

Q3: What is better aluminum or vinyl railings?

A: Whether aluminum or vinyl railings are better depends on your specific needs and preferences. Aluminum railings are typically stronger and more durable than vinyl, offering better structural support and resistance to impact. Vinyl railings, however, do not require painting and resist staining. In terms of maintenance, both are low-maintenance, but aluminum can handle harsher conditions without sustaining damage. For overall strength and durability, aluminum often has the advantage; for cost and ease of installation, vinyl might be preferable.
