Mid-back Grandstand Seat

All raw materials of our mid-back grandstand seats are virgin HDPE pellets
without recycled waste or mixed reprocessed plastics, fundamentally solvingcommon defects of cheap split seats such as fading, brittleness and cracking after
1-2 years of use.

The formula has been adjusted through dozens of outdoor environment tests,olended with four functional additives: imported anti-UV masterbatch, low-temperature toughener, waterproof anti-aging modifier and surface wear-resistant particles. Test samples are reserved for every raw material batch toguarantee consistent performance of all finished seats.

Our workshop is equipped with multiple full-automatic large hydraulic injectionmolding machines adopting one-piece integrated molding technology. The seatpan, backrest and bottom mounting base are fused into a single solid unit withoutsplicing gaps, snaps or assembly screws. It completely avoids the hidden dangersof split seats, including loose fasteners, dust and water accumulation in gaps, andfracture under force after long-term use
The raw material withstands temperatures from -55°C to 100°C. It will notharden or crack outdoors in frigid northern winters, nor whiten, bulge, deform orpeel under intense summer sunlight in southern regions. The matte anti-slip finetexture on the surface accelerates rainwater drainage without standing waterand mold stains. Daily cleaning only requires simple flushing with clean water,drastically cutting venue maintenance labor and supply costs.

There are thre mainstream types of bleacher seats on the market: low- back, mid -back and high- back each with obvious drawbacks. Ourmid-back seat balances
Derformance by solving real pain points of venue operation. Low backseats only support hips, leaving the walist and back suspended. leading to severe sorenessaftermore than one hour of sting during games orassemblles making them unsuitablefor long duration matches and performances Overskzed high back seats occupyexcessive horizontalspace,reducing the total number of seats on bleachers and venue passenger capacity while narrow gapsbetween seatscause frequent colisions
when spectators stand up and pass through aisles.

Aflat blank area is reserved on the backrest,supporting screen printing, hot stamping, UV printing and other processesto print venue names, event logos and seatnumbers. The printing layer features strong acheston and wil no peelor blur under long term wnd and sunlight exposure,faclitating venue Zone management and quick seat location for audiences.

All finished seats are sent to an authoritative third-party testing institute formechanical safety inspection before delivery, with a static ultimate load capacityof 300kg per seat, far exceeding the average adult weight standard. It fullywithstands heavy public usage scenarios including multiple people leaning.children jumping, dense crowds sitting after events and temporary heavy objectplacement. The seamless one-piece structure delivers excellent impactresistance: high-speed ball impacts on courts, crowd pushing and tool knocks willnot cause fractures, cracks or gaps on seats. The raw material features highinherent toughness; it only deforms slightly under external compression andrebounds automatically once pressure is removed without permanent dents ordamage.

Specialwear-resistant modfifed particles are blended into raw materials for high-frequeny siting and standing in 8ymnasiums and school bleachers. No white abrasionmarks or peeling wil appear on the surface after tens of thousands of friction yces retaining uniform intact color for years.HDPE materal s naturaly ant corrosion.rust proof and acid -baseresistant, resisting damagefromrainwater soaking,spectator sweat and venue disinfectants Unlike rust-perforated metalseats and mold-rotted wooden seats, our plastic mid-back seats sufer almost no loss, 8reatly cuting regular venue maintenance and seat replacement costsEquipped with an interalanti-aging systemfor open -ali venues the seats resistlarge -area fading and surface chalking over a ful 10 year servicelife.
