① Stadium seat appearance
Size of stadium seat according to ergonomics principle design, comfortable stadium seat, compact structure, safe and durable, easy to install, maintenance. The overall shape of the seat is novel and chic, the surface is soft and exquisite and generous.Fine steel double spring turning mechanism, mute folding, strong reliability. Various installation methods can be one of the best choice for indoor and outdoor stadium seat.
② Stadium seat Plastic Parts
Backrest and seat plate are designed according to ergonomics principle, which can fit the human body curve to the maximum extent. The material is made of pure PP raw material and nitrogen gas auxiliary molding. The material has good impact resistance, toughness, good mechanical strength and chemical stability, which makes the seat reliable and wear-resistant and comfortable to sit. The flame retardancy reaches B1 grade, through SGS the European fire proof mark, the harmful substance discharges the
③Mechanical loading of Stadium Seat
Seat design force 200 kg/, Static load test according to standard GB/T 10357.3 standard: seat plate 2000 N, Backrest 760 N, 10; Combined durability test: seat plate 950 N, Backrest N,330 200,000; After the test, there is no fracture or fracture of the seat; There is no obvious deformation in the loading part; The structure is not loose. The four-level standard of European mechanics passed the SGS test (the EN 12727：2016 test reached level 4); ANSI/BIFMAX5.4-2012. of Standards for Mechanics
④Left (right) engine of stadium seat
The left and right side of the seat is located on both sides of the seat, is a hardware link seat component, is the test seat plate can force the mechanism, the material uses the high fiber nylon, the strength is higher than the aluminum alloy, and so on partial conventional metal, has the outstanding toughness, the wear resistance, Further increase the seat sense, while ensuring the seat strength
⑤ stadium seat metal metal part
Back joint, middle flip mechanism, aluminum alloy material, spring using fine steel material, design as double spring mechanism, ensure spring back strength, durability, etc. Aluminum alloy parts adopt casting aluminum technology, surface spray powder, make the surface clean and bright, Comfortable and beautiful, durable.
⑥Stanchion of stadium seat
The vertical support is composed of two symmetrical 5 mm thick square cold rolled plates and a 5 mm thick square bottom plate. After cutting the bed, laser cutting makes the corner round and side neat, simple structure, convenient installation and high strength. The stability of the seat system can be guaranteed.
⑦Beam of stadium seat
The high strength aluminum alloy is selected by extrusion die, and the internal structure is designed as four triangular structures with mutual force, which makes the aluminum beam uniform, high strength and not easy to deform. High temperature T6 hard treatment, hardness up to 12-15, to ensure the stability of the stand system.
⑧Upholstery of stadium seat
Polyurethane high resilience cutting sponge, seat sponge thickness 2.0 cm, back sponge thickness 1.5 cm, surface palpable material for polyester fibrosis compound added 5% nylon, cloth wear resistance, strong elasticity, sponge and cloth spray plant glue, so that sponge and palpable cloth, cloth surface is not easy to wrinkle, formaldehyde emissions less than E1 grade.

Frequently Asked Questions
What is the minimum order quantity and the lead time?
The minimum order quantity for the Shell folding seat is 300 seats, and lead time is 15–30 days after order confirmation (depending on seat quantity, colour, upholstery choice and whether a custom logo mould is required). Production capacity is 2,000 seats per day in our 14,000 m² factory, so larger stand projects can be scheduled in phases.
What are the dimensions and material of the Shell seat?
Each Shell folding seat measures 435 × 552 × 782 mm and the seat shell is produced in PP using nitrogen gas assisted moulding. Standard colours are red, blue, yellow and grey, and custom colours can be produced.
How does the folding mechanism behave in daily use?
The seat is a split, foldable design fitted with a damping device, so it folds in a controlled way instead of dropping. A built-in gas structure supports the seat for comfortable sitting, which is why it is specified for both indoor and outdoor venues.
What is the seat frame made of?
The seat frame is 5 mm cold-rolled steel plate with hot-dip galvanizing or powder coating. The crossbeam that carries the seats is aluminium AL6063-T6, extruded and T6 hardened, using a multi-grid triangular support structure that distributes force evenly and resists deformation.
Can we add armrests, cup holders or upholstery?
Yes. Shell is available with optional armrests and cup holders, and with sofa cushions or PU cushions. Tell us the venue type and the row spacing you plan to use, and we will confirm the recommended configuration.
Can it be installed on different types of stand structures?
Yes. The crossbeam design facilitates seat installation and centre-distance adjustment, and the seat is used on steel structure stands as well as fixed and retractable stands.
What warranty and service life do you offer?
The seat carries a 2-year warranty with an expected use life of 10 years, and is tested to SGS, ISO 4892-2 (accelerated weathering) and BS 5852 (ignition resistance of upholstered seating).
Can we match our venue colours and add our logo?
Yes. Seat colours are produced with professional colour masterbatches and custom colours are available. An exclusive logo mould can be produced for customised branding, and colour-matched seats can be arranged to form large-scale logos or graphics across a stand.
