HD106250-S2N | Overflow Grating 250mm Wide x 20mm, Double Spine

Premium Wide-Format Grating with Maximum Structural Performance

When your pool installation demands both the expanded coverage of 250mm width and the superior strength of double spine construction, the HD106250-S2N delivers the ultimate combination of capacity and durability. This premium overflow grating represents the intersection of wide-format design and enhanced structural engineering—ideal for large-scale commercial installations, high-traffic resort pools, or prestigious residential projects where compromise simply isn’t acceptable. At 250mm wide with dual reinforcement, this is grating built for the most demanding applications.

What Makes 250mm Double Spine Grating Special?

As a retailer of hot tub spare parts, I’ve learned that certain applications demand the absolute best components available, and the HD106250-S2N answers that call. This grating combines two premium features—extra width and double spine construction—creating a product that exceeds standard offerings in multiple dimensions simultaneously.

The 250mm width provides 25% more coverage than standard 200mm grating, enabling broader overflow channels and increased water collection capacity. The double spine construction adds twin parallel reinforcing ribs instead of a single central support, dramatically increasing load-bearing capacity and structural rigidity. Together, these features create overflow grating capable of performing flawlessly in situations where standard components would prove inadequate.

The Synergy of Width and Strength

Why Combine Wide Format with Double Spine?

The combination of 250mm width and double spine construction isn’t arbitrary—it addresses specific challenges that arise when pools grow larger and more ambitious:

Span Management: Wider grating means longer unsupported spans between support points. Double spine construction provides the rigidity needed to prevent sagging or flexing across these extended distances.

Load Distribution: The 250mm width distributes loads across a broader area, and the double spine ensures those loads are transferred efficiently to the supporting channel structure without excessive deflection.

Scale Appropriateness: Large pools demand substantial components. The 250mm double spine design provides visual and structural presence appropriate to impressive installations.

Performance Assurance: In high-stakes applications—major resorts, public facilities, showcase residential projects—the combined features provide confidence that performance will meet expectations under all conditions.

Enhanced Structural Characteristics

The double spine architecture in a 250mm width format delivers exceptional performance:

Superior Rigidity: Two parallel reinforcing ribs across 250mm width create a structure that remains remarkably rigid even under concentrated loads or challenging conditions.

Minimal Deflection: The twin support system ensures the grating maintains its geometry and position even when subjected to heavy furniture, equipment, or snow loads.

Improved Load Capacity: Can support significantly greater loads than single spine alternatives of any width, making it suitable for the most demanding applications.

Extended Span Capability: The enhanced structure allows greater distances between support points in the channel system, potentially simplifying channel design and installation.

Long-Term Stability: Maintains dimensional stability and performance characteristics over extended service life, even in challenging environments.

Key Features and Benefits

Dual Reinforcement Architecture

The defining characteristic of this grating is its twin parallel structural ribs:

Engineering Advantage: Two support members rather than one fundamentally changes how the grating responds to loads. Forces are distributed between multiple load paths, reducing stress on any single component.

Material Optimization: The double spine design positions reinforcing material where it provides maximum structural benefit—creating exceptional strength-to-weight ratio.

Reduced Stress Concentration: Loads spread across two spines prevent the stress concentration that can occur with single central supports, reducing fatigue and extending service life.

Enhanced Connection Strength: The dual spine structure provides more robust attachment points where grating sections connect, creating more secure joints.

Premium 250mm Width

The substantial width offers distinct advantages:

25% More Coverage: Compared to standard 200mm grating, each meter of 250mm grating covers significantly more area, reducing the number of sections needed for a given perimeter length.

Increased Water Handling: Wider coverage means greater capacity for water overflow, essential in high-use situations or pools with wave generation, slides, or diving features.

Visual Impact: The substantial width creates a bold, premium appearance that signals quality and attention to detail—important in upscale residential and commercial installations.

Design Flexibility: The wider format provides more options for accommodating curves, transitions, and architectural details in sophisticated pool designs.

20mm Professional Profile

Despite the premium width and dual spine construction, the grating maintains the standard 20mm depth:

Universal Compatibility: Works with standard coping heights and deck levels used throughout the industry.

Clean Integration: Low profile ensures the grating doesn’t protrude excessively above surrounding surfaces.

Professional Appearance: Maintains sleek, contemporary aesthetics while delivering superior performance.

Installation Consistency: Matches the depth of other overflow grating, allowing mixing of different widths or spine configurations if needed.

Advanced Material Composition

Manufactured from premium-grade HDPE or UV-stabilized polypropylene with enhanced formulation:

Superior UV Stabilization: Advanced additive packages provide exceptional resistance to sun degradation, maintaining properties and appearance for decades.

Enhanced Chemical Resistance: Formulated specifically for continuous exposure to aggressive pool chemistry including high chlorine, bromine systems, and salt chlorination.

Optimized Impact Resistance: Material composition balanced for maximum impact resistance while maintaining flexibility needed for installation and thermal expansion.

Temperature Performance: Maintains structural integrity across extreme temperature ranges from sub-freezing to intense heat.

Premium Finish: Superior surface finish quality with consistent texture and appearance across all sections.

Commercial-Grade Anti-Slip Surface

Enhanced textured surface designed for safety in demanding environments:

Maximum Traction: Aggressive yet comfortable texture provides superior slip resistance critical in commercial settings.

Regulatory Compliance: Meets or exceeds safety standards for commercial pool deck surfaces.

Durability: Texture maintains effectiveness even after years of heavy traffic and exposure.

Comfort Balance: Provides excellent traction while remaining comfortable for bare feet.

Robust Connection System

Engineered connection mechanism ensures secure section-to-section joints:

Positive Locking: Connections engage positively to prevent unintended separation.

Load Transfer: Efficiently transfers loads across connections between sections.

Alignment Maintenance: Keeps sections properly aligned relative to each other.

Disassembly Capability: Despite secure connections, sections can still be removed for maintenance access.
