Stadium pavilion seating material technology introduction
Stadium seating is specifically designed for use in auditoriums, stadiums, and large public venues. These seats are engineered to provide comfort, durability, and aesthetic appeal, making them ideal for both indoor and outdoor environments.
**I. Development and Production of Stadium Seating Types**
**Plastic Stand Chairs**
The plastic stadium seat is manufactured using imported high-quality polyethylene and a blow-molding process. This ensures a smooth, durable finish with excellent weather resistance and easy maintenance. The design is modern and widely used in various public spaces due to its lightweight and long-lasting performance.
**FRP (Fiberglass Reinforced Plastic) Stand Chairs**
These chairs feature a smooth surface that resists weathering, chemicals, and aging. They are available in a wide range of colors and are commonly used in stadiums and halls. Custom color options are also available to meet specific design requirements.
Stadium stand seats are typically made using either injection molding or blow-molding techniques. The materials used offer excellent stability, a sleek appearance, and strong structural integrity. Features such as elastic feet and impact resistance make these seats highly practical for high-traffic areas.
**Excellent Material**
The material used is specially formulated with high-quality pigments, UV absorbers, and antioxidants from leading global suppliers like CIB. This ensures long-term durability and vibrant color retention.
**Good Strength**
The mechanical properties of the seats exceed national standards. For example, the seat can withstand an impact of 80 kg from a height of 300 mm, and the chair legs can support over 700 kg vertically. The large beam spacing (160 mm) allows for greater resistance to lateral movement.
**Superior Performance**
After undergoing extreme temperature tests (ranging from -50°C to +75°C), these seats have proven their reliability in diverse climates, from equatorial islands to snowy regions. They continue to perform well even after years of exposure.
**Corrosion Resistance**
All metal parts are treated with electrostatic spray painting after phosphating and pickling to prevent rust. The design also includes hidden mounting points for easier cleaning and maintenance.
**Types of Seats by Production Method**
a. Injection-molded chairs
b. Hollow blow-molded chairs
**Types of Seats by Shape**
a. Flat back chairs
b. Low back chairs
c. Medium back chairs
d. High back chairs
e. Split (upset) chairs
**Installation Methods**
a. Iron foot – floor-mounted
b. Iron foot – side-mounted
c. Iron foot – upright-mounted
d. Aluminum foot – side-mounted
e. Aluminum foot – upright-mounted
**Optional Accessories**
a. Handrails
b. Cushions
c. Coffee table frames
d. Footrests
e. Anti-aging agents
f. Flame retardants
**Abrasion Resistance**
Hollow blow-molded seats have excellent toughness and resistance to environmental stress cracking, ensuring long-term usability.
**Water Repellency**
The material prevents staining from spills and liquids, maintaining the appearance of the seat over time.
**Color Stability**
The color formula uses premium color masterbatches from American PuLiWan and Japanese DIC companies, ensuring the seat maintains its bright color for many years without fading or cracking.
**II. Special Technical Measures**
To ensure optimal performance in outdoor environments, several technical measures are implemented during installation:
1. Light stabilizers are added during production to maintain color vibrancy over time. Metal components are phosphated, pickled, and treated for rust and corrosion resistance.
2. The seat surface includes self-draining holes to prevent water accumulation. A self-cleaning finish helps maintain cleanliness, and the seats are securely anchored to the ground. All sealing holes are watertight to avoid leaks.
3. The seats are designed with sufficient strength and anti-sloshing features. They are installed in groups to minimize the impact of individual seat failures on surrounding units.
