About football game, do you know how many seats in football stadium, what kind of seats or chairs in one football stadium? The seats of the stands occupy two-thirds of the stadiums. If the space of the stands is used well, the utilization efficiency of the whole stadium will be greatly improved. Therefore, a suitable grandstand seat is very important for the construction of the stadium. So, how to choose the grandstand seats? Let’s take a look at the following 4 kind of seats.
Injection molding seat: modified PP polypropylene
Polypropylene is a colorless, odorless, non-toxic, translucent white waxy solid substances. Refined with fiberglass and UV protection additives, this modified PP polypropylene seat has the following advantages:
Advantages:
1. Features: new design, fine craftsmanship, long service life, corrosion resistance.
2. Excellent materials: The injection-molded seat is made of imported high-strength polypropylene. Adding the international industry standard special plastics, pigments, UV additives, and antioxidants make these seats more durable.
3. High strength: in line with international standards, mechanical properties exceed national standards.
4. Excellent performance: It is made of high-strength moisture-proof polypropylene and special self-extinguishing resin injection molding. It has been subjected to high and low temperature resistance and artificial accelerated aging tests, and has a long service life.
It can be installed on general foundations easily. Using durable stainless bolt, this PP seat is suitable for daily seats and grandstand seats in all stadiums.
Disadvantages: The structure is complex and the cost is relatively high.
Blow molding seat: HDPE polyethylene
The blow molding chair is made of high-grade HDPE polyethylene. This seat is more durable by adding the international standard special plastics, pigments, UV additives, and antioxidants.
Advantages:
1. Long service life. The hollow blow molded seat is made of imported polyethylene. One-time molding process has a beautiful appearance and smooth lines surface. With he characteristics of strong durability and strong weather resistance, it is easy to wash and can be used in daily stadium places. It can be easily and quickly installed on the normal foundation. The permanent parts are firm and durable, suitable for the daily use of stadium seats. The sponsor’s logo on the seat can be installed or removed at any time. This new design hollow blow molded seats has long service life, usually up to eight years or more.
2. Easy to clean. The cleaning of the hollow blow-molded seat is very simple, just wipe or wash the surfaces on time. Don’t worry about the hollow blow molding seat being deformed and faded by the sunlight. The seat adopts imported polyethylene and hollow blow molding process, which can be easily and quickly attached to the normal foundation.
3. Durability. The new design hollow blow molding seat is designed in long service life for more than 8 years. The structure of the hollow blow-molded seat is reasonable and reliable. The seats with the simple structure and smooth lines make it more sturdy and durability, and also strong weather resistance. Using the environmental protection material, the seat is corrosion resistance, high temperature resistance, high strength, high rigidity, non-toxic and not afraid of tide.
4. High strength: in line with international standards, mechanical properties exceed national standards.
Disadvantages: simple function and appearance. But high quality blow-molded seats are not low-grade, and the cost is relatively high.
Aluminum alloy seats
Metal seats: Metal seats are generally made of steel plates and aluminum plates. Bench seat is the most popular style. Using the welding technology to complete the whole structure, and then corrosion protection method of hot-dip galvanizing, this bench is finished with the following advantages: moisture proof, waterproof and corrosion resistance. This seats can be used is suitable for all stadiums, but it is mostly used for outdoor situations.
Made of aluminum alloy material, the bench seats in simple structure and competitive price has the characteristics of light weight, corrosion resistance, high strength, rigidity, non-toxic, high temperature resistance, strong fire resistance, long service life and moisture proof. The bench with the smooth surface is easily to clean. Designed with invisible flow hole, the bench is finished with fine craftsmanship. The pollution-free production process is comply with green environmental protection requirements. There are two options of low back and flat seats for the bleacher seats to meet the demand in various occasions.
Advantages:
Portable: All parts of the bench can be combined. Components are fixed by rubber sleeve pulleys.
Saving space: When the bleacher is not in use, it is easy to rotate the step members from the horizontal position to the vertical position due to the light weigh to the materials .
Demountable: The bench of the bleacher system can be combined, disassembled and assembled whatever and whenever you want. Other functional components can also be added.
Quick assembly bleacher: Quick assembly bleacher is a new type of temporary stand system, which can be combined arbitrarily.
Disadvantages: the bench is not comfortable enough for the hard seat plank. Under high temperature environment, the temperature of aluminum alloy plate also rises rapidly.
Wooden seats
Made of natural wooden materials, the wooden chairs in stadium have the following advantages:
Advantage:
1. Natural, environmentally friendly and healthy solid wood material reveal the beauty of nature.
2. As the wooden seats is using the natural raw material, so the seats looks more beautiful at first sight. Natural texture, changeable shape and beautiful wood patterns, all can generally be seen on the surface of furniture.
3. The solid wood chair has its own unique style and personality. The raw material of solid wood furniture comes from nature, which integrates the essence of nature and shows the truth.
Disadvantages: when the temperature changes, the materials is easy to expand or contract. With the original crack in the surface, the wooden seats need to be polished before used. In this case, the wooden seats is with short service life and is only used indoors. Many seats only use wood as the seat handle. Usually the stadium seats adopts the wooden materials as the armrest for long time shelf life.
