Key Features & Benefits
- Two distinct shell material options — HDPE mono-shell or polyurethane cold foam core with wood lining and textile/leather cover — allow the YH-CY2 to be specified as a hard-shell waterproof outdoor seat or an upholstered seat with decorative wood backrest within a single part number, covering the full range of outdoor football field and stadium seat specifications from utilitarian bleacher rows to hospitality-tier seating.
- Waterproof backrest contoured bucket geometry on the HDPE mono-shell option channels surface water off the seat and backrest faces during rainfall — a functional design parameter for outdoor football field, sports venue, and open-air concert hall installations where seats remain exposed between events and surface water retention degrades both material and occupant experience.
- Four installation methods — beam floor-mounted, beam riser-mounted, independent riser-mounted, and metal grandstand matching — provide the broadest confirmed mounting configuration range in the product series, allowing a single seat model to be specified across new-build stadium tiers, concrete riser retrofits, independent post-mount arrays, and metal grandstand platform integration.
- Three confirmed mounting height profiles — riser (715±5mm), floor (679±5mm), and independent riser (696±5mm) — with ≥457mm center-to-center spacing provide the geometric parameters required for sightline engineering, row spacing calculations, and structural engineer seat layout drawings without additional site survey data.
- Galvanized steel roll-forming or aluminum extrusion support beams, with powder coating post rust-proofing or hot-dip galvanization surface finish options, provide four confirmed corrosion protection configurations — allowing the beam and finish specification to be matched to the atmospheric exposure level and maintenance budget of each outdoor venue installation.
- BS EN 12727:2000 mechanical strength and durability, BS 5852:2006 fire resistance and ignitability, and DIN4102-1 flammability certification provides the three-standard public assembly compliance set applicable to outdoor stadium seating across UK-licensed, European, and international venue authority specification requirements.
Applications
- Installed at municipal football field venues where the HDPE mono-shell waterproof backrest geometry and galvanized steel beam with hot-dip galvanization finish provide weather-resistant, low-maintenance seating across fully exposed outdoor installation conditions without recurring surface treatment requirements.
- Deployed at university outdoor stadium seating installations where ≥457mm center-to-center spacing, three confirmed mounting height profiles, and BS EN 12727:2000 structural certification support venue authority sightline approval and seating density calculations for publicly accessible sports venues.
- Specified for outdoor metal grandstand retrofits where the metal grandstand matching installation method integrates the YH-CY2 directly with existing steel grandstand platform profiles, and the optional armrest, cupholder, and seat number accessories complete the seating specification without procurement of additional accessory hardware.
- Used at commercial sports venue bleacher installations where the choice between HDPE mono-shell and polyurethane foam/wood/fabric shell allows a single model to serve both general admission bleacher sections and hospitality or VIP tier specifications within the same venue project.
- Deployed at high-traffic open-air concert halls where the optional hidden slow rebound spring folding mechanism, anti-UV and anti-weathering material properties, and DIN4102-1 flammability classification meet the functional, maintenance, and fire compliance requirements of multi-use outdoor public assembly venues.
FAQ
Q1: What are the dimensional footprints and center-to-center spacing parameters for layout planning?
The YH-CY2 seat is 410±5mm wide and 404±5mm deep, with a confirmed minimum center-to-center spacing of ≥457mm. Three mounting height configurations are available: riser mounting at 715±5mm, floor mounting at 679±5mm, and independent riser mounting at 696±5mm — providing the full geometric dataset required for stadium row spacing and sightline engineering calculations.
Q2: What are the structural material options and anti-corrosion surface treatment specifications?
The seat shell is available as an HDPE mono-shell (Option A) or a polyurethane cold foam + wood + fabric/leather upholstered assembly (Option B); support beams are galvanized steel roll-forming or aluminum extrusion; brackets are galvanized steel or aluminum pressure casting. Surface finish is powder coating applied post rust-proofing treatment, or hot-dip galvanization — providing two confirmed corrosion protection methods selectable by exposure level and maintenance specification.
Q3: What do BS EN 12727:2000, BS 5852:2006, and DIN4102-1 certify for outdoor football field seating procurement?
BS EN 12727:2000 certifies mechanical strength and durability under structural loading; BS 5852:2006 certifies fire resistance and ignitability performance; DIN4102-1 provides flammability classification parameters. The three-standard set provides the structural load capacity, fire resistance, and flammability documentation required for outdoor public assembly seating specification across UK, European, and international venue authority submissions.
Q4: What installation methods and optional accessories are available for layout and feature flexibility?
Four installation methods are confirmed: beam floor-mounted, beam riser-mounted, independent riser-mounted, and metal grandstand matching — covering new-build, retrofit, independent post, and grandstand platform integration applications. Optional accessories include armrests, cupholders, mechanical writing boards, seat numbers, and add plates, allowing the base seat to be configured for general admission, hospitality, educational, or multi-use venue specifications within a single part number.
