Product Application
Balustrade (Rail & Baluster)
Belco XT® balustrade elements provide the perfect balance of strength and style, offering superior performance for both rail and baluster applications.

BELCO XT® Balustrade
Built for Strength and Style
A balustrade system consists of two key components: rails and balusters. Rails are the horizontal structural elements that provide stability and support, while balusters are the vertical members that create a secure, stylish barrier. Belco XT balustrade components are manufactured from preservative-treated wood, offering durability and resistance to rot, decay, and insect damage while ensuring timeless curb appeal.
FORM MEETS FUNCTION
Safety You Can Trust, Beauty You Can See
In addition to elevating porch design, Belco XT balustrade materials deliver both safety elements and structural integrity to exterior spaces. Engineered for ground-level porches or multi-story balconies, our rail and baluster materials provide the efficiency and stability that professional installations demand, while maintaining clean, architectural lines that complement any design specification. The preservative and prime treated Belco difference ensures long-term performance in exposed conditions, reducing callbacks and enhancing project reputation. When builders expect both security and beautiful craftsmanship, Belco XT delivers on both fronts.
INSTALLATION BEST PRACTICES
Application and Installation Information
Proper installation is key to ensuring the longevity and safety of any balustrade system. All rails and balusters should be securely fastened and spaced according to local building codes to maintain structural integrity and safety:
- Rails should be securely anchored to posts to provide a stable framework.
- Balusters must be evenly spaced to meet safety standards and prevent excessive gaps.
- Fasteners should be corrosion-resistant and rated for exterior use to prevent deterioration over time.
- Proper drainage around the base of posts and rail connections will help extend the life of the wood.
COMMON SIZES
Rail & Baluster Common Sizes
Belco XT Corner Trim comes in 10 and 20 feet lengths to suit various construction needs. The 10-foot length is ideal for standard applications, while the 20-foot length significantly reduces installation time, especially on multi-story projects. By minimizing seams and eliminating the need for horizontal butt joints, the 20-foot trim provides a smoother, more seamless finish and reduces potential moisture intrusion points.
The longer 20-foot length also simplifies installation by requiring fewer cuts and fasteners, making it an efficient choice for builders. This is particularly beneficial for second-story corners, which are harder for homeowners to maintain. With fewer joints to seal and maintain, Belco XT Corner Trim ensures a durable, high-quality finish while saving time and labor costs.

COMMON MATERIALS
Choosing the Right Balustrade Material
Balustrade systems are crafted from a variety of materials, each offering unique advantages based on regional climate, architectural style, and maintenance requirements. Wood is a classic option, valued for its natural beauty and versatility. Traditional choices such as cedar and redwood provide durability but often come at a higher cost and require regular maintenance to prevent weathering. Metal balustrades, including wrought iron and aluminum, offer a sleek, modern aesthetic and strong structural integrity, though they can be prone to corrosion over time, especially in coastal environments. Vinyl and composite materials are valued for their low-maintenance appeal, but may lack the warmth and character of real wood and are susceptible to fading and brittleness in some climates.
For projects requiring the aesthetic appeal of wood with enhanced durability, Belco XT balustrade stands apart. Made from high-quality sustainably sourced SPF, these rails and balusters provide the strength and classic look of real wood while offering outstanding resistance to moisture, rot, and insect damage. Additionally, Belco XT Trim components always arrive factory-primed for excellent paint adhesion and long-term performance. With versatility to suit a range of architectural styles, Belco balustrade materials are the preferred choice for builders and architects seeking a balance of timeless beauty, efficient installation, and top-notch resilience.
