Material & Durability of Line Array Brackets

The longevity and performance of sound system hardware—particularly line array brackets—are directly influenced by the materials used in their construction. These components must withstand significant mechanical stress, environmental exposure, and repeated setup/teardown cycles. Selecting the right materials ensures structural integrity, safety, and extended service life, especially in demanding environments like concert halls, touring productions, and outdoor festivals.

Brackets: Steel vs. Aluminum Construction

Steel Brackets

Steel is renowned for its exceptional strength and resistance to deformation under heavy loads. Line array brackets made from high-grade steel can support large speaker configurations, making them ideal for permanent installations or large-scale touring systems.

While heavier than aluminum, steel provides unmatched durability and rigidity. It is often used in fixed rigging systems where weight is less of a concern than load capacity and long-term reliability.

Aluminum Brackets

Aluminum offers an excellent strength-to-weight ratio, making it a preferred choice for mobile and touring applications. Aircraft-grade aluminum alloys are commonly used due to their ability to resist fatigue while remaining lightweight.

This reduces the overall load on rigging points and makes transportation and setup significantly easier. Though not quite as strong as steel, modern aluminum brackets are engineered to meet rigorous safety standards without compromising performance.

Mounting Plates: Load Distribution & Structural Integrity

Mounting plates serve as the critical interface between the bracket and the supporting structure (e.g., trusses, beams, or ceiling mounts). Typically constructed from the same materials as the brackets—steel or aluminum—these plates are designed with increased thickness to handle concentrated stress points.

By distributing the load across a broader surface area, mounting plates minimize the risk of structural failure at connection points. Premium models often feature reinforced edges, gussets, or multi-point attachment designs to enhance stability during high-vibration events such as live concerts or festivals.

Safety Cables: Redundancy and Stress Management

Safety cables are a vital component of any rigging system, acting as a secondary fail-safe in case the primary support fails. Constructed from either galvanized steel wire rope or aircraft-grade aluminum cable, these cables are engineered to endure extreme tensile forces while remaining flexible and lightweight.

They function as part of a load-sharing system, ensuring that no single point bears the full weight of the array. This redundancy is essential for compliance with safety regulations and provides peace of mind during operation. Regular inspection of safety cables is crucial, as even minor fraying can compromise their effectiveness.

Polymer Components: Protection & Wear Resistance

While the core structural elements are metallic, many line array brackets incorporate polymer components for added protection. These include bushings, spacers, or protective sleeves made from high-impact plastics such as nylon or polyurethane.

In addition, some brackets feature polymer coatings or inserts that reduce metal-to-metal contact, minimizing wear and noise during adjustments. These materials also help absorb vibrations and protect against minor impacts during transport and installation.

Coatings & Corrosion Resistance

Exposure to moisture, humidity, and temperature fluctuations—especially in outdoor or coastal venues—can lead to rust and corrosion in untreated metals. To combat this, many manufacturers apply protective finishes such as:

Powder Coating: A durable, weather-resistant finish that protects against scratches, UV degradation, and oxidation. Available in various colors for aesthetic customization.

Zinc Plating (Galvanization): Commonly used on steel components to prevent rust by creating a sacrificial barrier layer.

Anodizing: Applied to aluminum parts, this electrochemical process enhances surface hardness and corrosion resistance while maintaining a clean, professional appearance.

Stainless Steel Options: For maximum durability in harsh environments, some brackets and mounting hardware are made entirely from stainless steel, eliminating the need for additional coatings.
