Product material and material description:
Stadium seating using high density polyethylene (HDPE) as raw material, hollow blow molding; seat color selected professional coloring masterbatch. Material characteristics:
- Polyethylene (HDPE) is imported raw plastic from Saudi Arabia BN;
- Anti-aging agent of Stadium seating is a special outdoor anti-aging agent imported from Switzerland;
- The use of high quality color mother coloring can ensure that the product will not fade for many years, durable and non-corrosive raw materials have good waterproof and impact resistance, good mechanical strength and chemical stability, and good weathering resistance (heat resistance and cold resistance).
Process and process description of Stadium seating:
Hollow blow molding has been widely used to produce a variety of thin shell Stadium seating hollow products, chemical and daily packaging containers, as well as children's toys.Hollow blow molding (also known as blow molding) is a method of blowing and forming hollow products by means of gas pressure. It is the most commonly used plastic processing method and a fast developing plastic forming method. The mould used for blow molding is only negative mould (concave mould). Compared with injection molding, the equipment cost is lower, the adaptability is stronger, the molding performance is good (such as low stress), and the products with complex undulating curve (shape) can be formed.
- Circular pipe material description of Stadium seating: the material is Q235, the material has moderate carbon content, good comprehensive performance, strong strength, plasticity and weldability. Hot dip on the surface can effectively increase the beauty and corrosion resistance of the product.
- Fastener material description of Stadium seating: material for Q235, surface hot dip zinc or powder spray treatment. Can effectively increase the beauty and corrosion resistance of the product
- Support foot material introduction of Stadium seating: material for aluminum alloy profile. The material has the advantages of low density, high strength, good conductivity, good corrosion resistance and easy processing.
- Application of Blocking Material of Stadium seating: Polymers made of vinyl are non-crystalline materials commonly known as PVC. materials The material is non-flammable, high strength, weather resistance and excellent geometric stability. And PVC have strong resistance to oxidants, reductants and strong acids.
ECO Series Design Features
The ECO series is our hollow blow-moulded bucket seat family for stadiums, arenas and school stands. The same seat shell can be mounted several ways, which is why one ECO model fits a wide range of grandstand layouts.
| Design element | Specification |
|---|---|
| Material and process | High-density polyethylene (HDPE), one-piece hollow blow moulding with an integrated hollow structure |
| HDPE grade | Model 5502, imported from Saudi BN |
| Durability | Water and impact resistant; excellent mechanical and chemical stability; heat and cold resistant |
| Seat type | Bucket seat, ergonomically shaped to fit the body curve |
| Installation options | Flat, wall and vertical mounting to suit different concrete grandstand heights |
| Backrest options | Three backrest heights across the ECO series |
| Seat identification | Optional aluminium number plates |
| Colour | Customisable with professional colour masterbatches for long-lasting bright colour |
Installation Methods
The ECO series is engineered for concrete grandstands: the same seat shell can be mounted flat, on the wall or vertically, so one model covers several stand heights without changing the seat.
| Mounting method | How the seat is installed | Requirement / benefit |
|---|---|---|
| Flat mounting | Seats are flat-fixed to the front edge of the step using custom brackets | Step height must be ≤ 350 mm, otherwise an over-high seat surface causes fatigue in prolonged sitting. Cost-saving, firm and stable for standalone seats |
| Wall mounting | Seats are fixed to the rear of the step with foot frames and brackets | Requires a step height of 300–550 mm; easy to clean |
| Vertical mounting | Seats are fixed to the rear of the step; the bracket height is fixed | Seat height stays 420–440 mm from the ground and is not affected by step height |
| Independent rear mounting | Seats are fixed to the rear of the step with foot frames and brackets | For venues with high audience comfort requirements; strong anti-interference between individually installed seats |
Hardware Components
| Component | Specification |
|---|---|
| Seat feet | Aluminium alloy profile with Dacromet coating (superior corrosion protection). Coating thickness 4–8 μm, rust-proof effect 7–10 times |
| Seat fasteners | Q235 steel, hot-dip galvanized |
| Galvanized round tubes | Q235 steel, hot-dip galvanized, supplied with dedicated PVC end caps |

Frequently Asked Questions
What are the dimensions and material of the Eco-L seat?
The Eco-L seat measures W415 × D410 × H162 mm and is made of high-density polyethylene (HDPE) by one-piece hollow blow moulding. Standard colours are red, blue, yellow and grey, and custom colours are available.
Which mounting method should we use on our stand?
It depends on your step geometry. Flat mounting fixes the seat to the front edge of the step and needs a step height of 350 mm or less. Wall mounting fixes it to the rear of the step and needs 300–550 mm. Vertical mounting keeps the seat 420–440 mm above the ground regardless of step height, and independent rear mounting gives the strongest anti-interference between individual seats for high-comfort venues.
How is the seat built and how does it hold up outdoors?
The shell is one-piece hollow blow moulded from HDPE grade 5502 imported from Saudi BN. The integrated hollow structure is water and impact resistant, with good mechanical and chemical stability and resistance to both heat and cold, so the seat is suitable for outdoor stands in hot and cold climates.
Do the ECO seats come in different backrest heights?
Three backrest heights are available across the ECO series; this model, Eco-L, measures W415 × D410 × H162 mm. Tell us the stand's step height, sightline requirements and whether the seats are for spectators, athletes or media, and we will confirm the right backrest.
How do you identify individual seats?
Optional aluminium number plates can be fitted for clear seat identification, which is normally requested for ticketed stands and media positions.
Can we match our venue colours and print our logo on the seats?
Yes. Seat colours are produced with professional colour masterbatches, and an exclusive logo mould can be made for customised production. Because seats are colour-matched, large-scale logos or graphics can be formed across a stand to reinforce venue identity.
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).
What is the minimum order quantity and the lead time?
The minimum order quantity for the Eco-L seat is 200 seats, and lead time is 15–30 days after order confirmation (depending on seat quantity, colour and whether number plates or a custom logo mould are required). Production capacity is 2,000 seats per day across 6 blow moulding machines and 2 air injection machines in our 14,000 m² factory. Send us the number of seats, the stand type (steel structure, fixed or retractable) and the row layout, and we will confirm quantities, mounting method and a delivery schedule.
