Stadium pavilion seating material technology introduction
Stadium seating is specifically designed for use in auditoriums and stadiums, offering comfort, durability, and aesthetic appeal. These seats are essential in large public spaces where a high volume of people need to be accommodated efficiently.
The development and production of stadium stand seating have evolved significantly, with various types available based on materials and design. One popular option is the plastic stand chair, which uses imported polyethylene and is manufactured through blow molding. This process ensures a smooth, uniform appearance with strong weather resistance, making it ideal for both indoor and outdoor use. The material is also easy to clean and long-lasting, which contributes to its widespread application.
Another common type is the FRP (Fiberglass Reinforced Plastic) stand chair. These seats feature a smooth surface that is resistant to weather, chemicals, and aging. They do not crack easily and come in a variety of colors, allowing customization according to user preferences. Their durability and aesthetic qualities make them a popular choice in modern stadiums and halls.
Stadium stand seats are typically made using either injection molding or blow molding techniques. The materials used are known for their stability, attractive appearance, and strong structural integrity. Features such as elastic feet and impact resistance enhance the overall performance of the seats.
High-quality materials, including special blow molding resins from global brands like Philip, are used to ensure longevity and excellent performance. Mechanical properties of these seats exceed national standards, with tests showing they can withstand heavy loads and repeated use. For example, a seat can endure an impact of 80 kg from a height of 300 mm, and the chair legs can support up to 700 kg vertically. The spacing between beams (160 mm) allows for greater resistance to lateral movement.
These seats are also treated with anti-rust and anti-corrosion measures. All metal parts are electrostatically sprayed and phosphated to prevent rusting. Additionally, the design includes hidden fastenings for easier cleaning and maintenance.
Stadium seating can be categorized based on production methods, seat shapes, and installation types. Injection chairs and hollow blow chairs are two main types. Seat shapes include flat, low back, mid-back, high back, and split designs. Installation options vary, including iron foot or aluminum foot models, mounted on the side or standing upright.
Optional accessories such as handrails, cushions, coffee tables, movable feet, anti-aging agents, and flame retardants can be added to enhance functionality and comfort.
The material used in hollow blow seats has excellent wear resistance and environmental stress cracking resistance. It is also water-repellent, preventing damage from spills or rain. The color formula uses imported color masterbatches from reputable companies like PuLiWan and DIC, ensuring vibrant and lasting color over time.
To adapt to outdoor environments, special technical measures are taken during installation. Light stabilizers are added to maintain color brightness, while metal components are treated for rust and corrosion resistance. The seat surfaces are designed with self-draining holes to prevent water accumulation, and the structure is firmly anchored to the ground. Sealing holes are watertight to avoid leaks.
In terms of performance, the high-density polyethylene used in hollow blow seats meets strict specifications. Key parameters include a melt flow rate of 0.25–0.35 g/10 min, density of 0.925–0.955 g/cm³, tensile strength of ≥26 MPa, elongation at break of ≥500%, and environmental stress cracking resistance of ≥20 hours. These features ensure that the seats perform reliably under extreme temperatures and conditions.
Overall, stadium seating is a critical component in public venues, combining practicality, aesthetics, and durability to meet the needs of large audiences.
