3. Core Product Features

3.1 Telescopic & Space-Saving Design

Adopts advanced multi-stage telescopic folding structure. The grandstand can be fully stretched to provide standardized spectator seating during events, and completely retracted into a compact state when not in use, maximizing the release of venue floor space. It effectively solves the space waste problem of fixed stands, enabling one venue to meet multiple usage needs and greatly improving the comprehensive utilization rate of sports and activity venues.

3.2 Stable & Safe Structural Performance

The main frame is made of high-quality thickened galvanized steel pipe, with integral welding and reinforced connection technology. The whole structure has strong bearing capacity, good wind resistance and shock resistance, and will not shake or deform when fully loaded with spectators. Equipped with anti-tilt device, automatic braking system and ground anti-slip fixing device, the grandstand can maintain absolute stability during stretching, shrinking and use, effectively preventing tilting, sliding and other safety risks, ensuring spectator safety in large-flow scenarios.

3.3 Flexible & Intelligent Operation

Supports two operation modes: electric automatic telescopic and manual telescopic. The electric model is equipped with intelligent control panel and one-key telescopic function, with stable transmission, low noise and fast operation. The manual model is labor-saving and flexible, suitable for small and medium-sized venues without power supply dependence. The telescopic speed is uniform and controllable, with anti-pinch and emergency stop functions, which can quickly stop operation in case of abnormal conditions, ensuring safe and convenient operation.

3.4 Ergonomic & Comfortable Seating Experience

Matching high-quality integrated molded seats and anti-slip standing pedals, the seat back and surface adopt humanized curved design to fit human sitting posture and reduce long-time sitting fatigue. All edges and corners are polished smoothly without sharp edges. The stand adopts step-by-step heightening design with scientific row spacing and height, ensuring unobstructed viewing vision for each seat, bringing comfortable viewing and sitting experience for spectators.

3.5 Wear-Resistant & Long Service Life

The steel frame is treated with hot-dip galvanizing and anti-rust spraying, which is anti-corrosion, anti-oxidation and not easy to rust and deform. The seats are made of high-strength HDPE or environmental plastic materials, with wear resistance, pressure resistance and aging resistance. The core transmission parts are made of high-precision wear-resistant accessories, which can withstand frequent telescopic switching and long-term high-frequency use. The overall service life of the equipment can reach more than 15 years, with stable performance and low failure rate.

3.6 Easy Management & Strong Versatility

The modular assembly structure is convenient for installation, disassembly and transportation. The surface of the equipment is smooth and dust-proof, easy to clean and maintain in daily life. The product supports customized stand layers, seat numbers, overall length and color matching, and can be equipped with armrests, guardrails, stair handrails, seat numbers and LOGO printing according to venue requirements.
