Blow Molded Stadium Seat W415×D410×H162mm for Bleachers and Retractable Seating

Technical Specifications

Key Features & Benefits

• Hollow blow molding shell geometry produces a twin-wall cross-section that distributes point-load stress across the seat face without reliance on internal bracing components.
• Saudi Arabia BN HDPE 5502 feedstock delivers a defined melt flow index and density profile, providing dimensional consistency across high-volume production runs.
• Anti-UV polymer stabilization inhibits photodegradation of the HDPE matrix under continuous solar exposure, preserving structural geometry and surface finish over the service life.
• Anti-aging compound integration retards oxidative chain scission in the HDPE base resin, maintaining impact resistance and flexural modulus through seasonal thermal cycling.
• Fire-proof formulation reduces flame propagation along the seat surface, a structural requirement for public assembly occupancy classifications under applicable venue codes.
• Three discrete mounting modes — flat, wall, and vertical installation — allow a single seat model to be deployed across fixed bench arrays, retractable bleacher decks, and telescopic bleacher frames without seat redesign.

Applications

• Installed in fixed-row outdoor stadium seating arrays where anti-UV and anti-aging performance requirements are driven by year-round solar exposure conditions.
• Deployed on retractable bleacher decks where vertical installation geometry and repeatable dimensional tolerance are required for reliable seat folding and retrieval mechanics.
• Integrated into telescopic bleacher systems where flat or wall installation modes interface directly with aluminum bleacher frame profiles in 3-, 4-, and 5-row configurations.
• Mounted on metal structure bleacher frameworks where the blow molded shell provides the primary occupant load surface and seat-to-frame connection is made through the standard mounting hardware interface.
• Specified for player bench shelter installations where fire-proof material classification and EN/SGS/BS/ISO certification documentation support venue authority approval processes.

FAQ

Q1: What are the confirmed seat dimensions and base material specification? The seat envelope is W415 × D410 × H162 mm, produced from HDPE 5502 sourced from Saudi Arabia BN. HDPE 5502 is a defined-grade high-density polyethylene with controlled melt flow and density properties relevant to blow molding process consistency.

Q2: How should buyers select between flat, wall, and vertical installation modes? Installation mode is determined by the bleacher frame geometry and seat actuation requirement. Flat installation suits fixed-row decks; wall installation anchors to vertical riser faces; vertical installation is used where seats fold upward on retractable or telescopic systems.

Q3: What is the outdoor atmospheric performance basis for this seat? The HDPE 5502 matrix incorporates anti-UV stabilizers, anti-aging compounds, and a fire-proof formulation. These three protective attributes address photodegradation, oxidative aging under thermal cycling, and flame propagation — the primary failure modes for polymer seating in outdoor public assembly environments.

Q4: What warranty coverage applies, and how are certifications validated? A 2-year manufacturer warranty covers the seat under standard installation and use conditions. Certification documentation under EN, SGS, BS, and ISO frameworks is available from the factory for procurement review; buyers should request specific test reports for the applicable certification standard required by their venue authority.
