HD106300-S2N | Overflow Grating 300mm Wide x 20mm, Double Spine

The Ultimate Overflow Grating Solution for Elite Pool Installations

When your project represents the absolute pinnacle of pool design—where maximum overflow capacity meets uncompromising structural performance—the HD106300-S2N delivers the ultimate combination available in standard overflow grating. At 300mm wide with double spine reinforcement, this represents the apex of engineered pool grating: 50% wider than standard dimensions with twin parallel structural ribs providing exceptional load-bearing capacity. This is the grating of choice for the most demanding commercial installations, world-class resort facilities, and prestigious architectural projects where nothing but the very best will suffice.

The Premium Pinnacle of Overflow Grating

As a retailer of hot tub spare parts, I’ve supplied components for projects ranging from modest residential pools to internationally-recognized aquatic complexes, and the HD106300-S2N sits at the absolute top of the overflow grating hierarchy. This product combines every premium feature available: maximum standard width for superior coverage and capacity, double spine construction for unmatched strength and rigidity, and high-quality HDPE manufacturing for durability that matches the most demanding applications.

This isn’t grating you choose because it’s adequate—it’s grating you specify because your project demands absolute excellence. The 300mm width provides 50% more coverage than standard 200mm grating, while the double spine construction delivers structural performance that far exceeds single spine alternatives of any width. Together, these features create a component capable of performing flawlessly in situations that would overwhelm lesser products.

Understanding the Ultimate Combination

Why Maximum Width Plus Maximum Strength?

The pairing of 300mm width with double spine construction addresses the most challenging requirements in modern pool design:

Extreme Span Management: The 300mm width creates substantial spans between support points. Double spine construction provides the rigidity essential to prevent deflection or sagging across these extended distances—something single spine construction cannot reliably achieve.

Ultimate Load Capacity: Large commercial pools experience loads that would overwhelm standard grating. The combination of width (for load distribution) and double spine (for structural strength) creates grating that can handle virtually any realistic loading scenario.

Professional Excellence: In world-class facilities—Olympic venues, luxury resorts, architectural landmarks—component selection signals commitment to quality. The HD106300-S2N makes that statement unequivocally.

Engineering Confidence: For projects where grating failure would be catastrophic—either structurally or reputationally—this combination provides the engineering margin necessary for complete confidence.

Future-Proof Performance: Installations built to last decades need components that won’t require replacement. The HD106300-S2N’s exceptional durability ensures it remains functional and attractive for the full lifespan of the pool.

Structural Engineering Excellence

The double spine architecture in 300mm width creates extraordinary performance characteristics:

Maximum Rigidity: Twin parallel reinforcing ribs across the full 300mm width create a structure of exceptional stiffness that maintains its geometry under all realistic load conditions.

Distributed Load Paths: Two structural members share loads, eliminating single-point stress concentration and reducing material fatigue.

Extended Span Capability: The enhanced structure allows greater distances between channel support points than any other grating configuration, potentially simplifying channel design.

Superior Connection Strength: Double spine structure provides more robust connection points where sections join, creating exceptionally secure joints.

Long-Term Dimensional Stability: Maintains precise positioning and levelness even after years of loading cycles and environmental exposure.

Key Features and Benefits

Twin Reinforcement Architecture at Maximum Width

The defining characteristic is the combination of features:

Dual Spine Design: Two parallel structural ribs positioned optimally within the 300mm width provide unmatched load-bearing capacity.

Engineered Optimization: The spacing and dimensions of the twin spines are calculated to maximize strength while minimizing material use and weight.

Load Distribution Excellence: Forces applied anywhere on the 300mm width are efficiently distributed between both structural members and transferred to supporting channels.

Stress Management: The architecture eliminates stress concentration points that cause fatigue failures in lesser designs.

Performance Reserve: Provides structural capacity well beyond typical loading, ensuring reliability even in unexpected circumstances.

Premium 300mm Width Specification

The maximum standard width delivers unparalleled advantages:

50% Expanded Coverage: Compared to standard 200mm grating, each linear meter provides half again as much coverage area.

Ultimate Overflow Capacity: Handles the most extreme water volumes generated by wave pools, competition swimming, diving platforms, or high-density bather loads.

Architectural Impact: Creates the most substantial, impressive perimeter treatment available in standard grating—appropriate to the grandest pool installations.

Reduced Section Count: Fewer individual sections needed for a given perimeter, reducing installation time and the number of potential connection points.

Design Statement: The substantial width signals premium quality and serious engineering—appropriate for installations where excellence is non-negotiable.
