Recently, Sheng Run Sports, a professional domestic source manufacturer of grandstand seats, released good news on market operation. The annual delivery volume of its flagship integrated injection molded mid-back grandstand seats has reached nearly 10,000 sets, covering various public viewing venues nationwide including primary and secondary school sports fields, comprehensive gymnasiums, professional football fields, scenic performance bleachers and theater lecture halls. Landmark cultural tourism projects such as Beijing Ocean Park adopted this model for complete audience seating supporting. Its reliable product quality and integrated engineering services have won high recognition from general contractors and school procurement teams.
Inside Sheng Run Sports standardized production park, four independent workshops operate simultaneously: self-developed mold workshop, full-automatic hydraulic injection molding workshop for mass seat production, metal bracket workshop for matching steel structure processing, and custom printing workshop for logo and seat number printing. The closed-loop full industrial chain realizes independent control of the whole process from raw materials to finished products. According to the enterprise's technical director, this mid-back seat is specially upgraded to solve industry pain points. Different from low-back seats with insufficient back support and space-wasting oversized high-back seats, its backrest height is adjusted after thousands of ergonomic sitting posture simulations. The curved surface fully supports the human lumbar spine to avoid waist and back soreness even after 2-3 hours of continuous sitting. Meanwhile, the optimized horizontal footprint allows more seats to be installed on bleachers of the same length, balancing viewing comfort and venue passenger capacity efficiency.
In terms of durability and safety performance, all seats are produced with virgin HDPE pellets without mixed recycled waste. The raw material formula is blended with imported anti-UV masterbatch, low-temperature toughener and wear-resistant modified particles, enabling the product to withstand extreme temperatures ranging from -55℃ to 100℃. It will not harden or crack outdoors in northern winters, nor whiten, chalk or deform after ten years of intense sunlight exposure in southern regions. The one-piece injection molding technology fuses seat pan, backrest and base into a single solid unit without splicing gaps, snaps or screws, eliminating risks of loosening and fracture after long-term use. The static ultimate load capacity reaches 300kg per seat. Every batch of finished seats is sent to authoritative third-party institutions for mechanical safety and environmental protection double inspection. The fully rounded edge design complies with national school safety standards, suitable for frequent activities of the elderly, teenagers and children.
The product features wide scene compatibility, matching four mainstream bleacher infrastructure structures: concrete fixed stepped bleachers, fixed steel bleachers, electric retractable folding bleachers and quick-assembly mobile bleachers. It can operate stably indoors, semi-outdoors and fully outdoors for decades. Dozens of regular colors including blue, red, orange, green and yellow are always in stock, while exclusive custom colors can be formulated according to venue VI visual systems. A flat blank area on the backrest supports screen printing, UV printing and hot stamping for brand logos and seat numbers. Two bracket options, hot-dip galvanized anti-corrosion steel and lightweight aluminum alloy, can flexibly fit different project budgets and service life requirements.
For government school procurement and large cultural & sports general contracting projects, Sheng Run Sports has built a full-process one-stop service system: professional technicians conduct on-site size surveys, provide seat layout renderings and detailed construction plans, arrange full-truck direct logistics delivery to construction sites, and assign dedicated installation teams to complete assembly, commissioning and handover. The direct supply model as a source factory eliminates markup from multi-layer intermediate distributors, effectively cutting overall project procurement costs. The factory opens its production park and finished project sites for on-site inspection all year round, welcoming purchasers nationwide to verify product performance and project implementation effects in person.
The person in charge of Sheng Run Sports stated that the enterprise has long focused on the public spectator seating track, taking independent R&D, self-production & self-operation and integrated engineering supporting as core competitive advantages, continuously upgrading the weather resistance, comfort and compatibility of its products. In the next stage, the factory will upgrade intelligent injection molding production lines and develop more lightweight, multi-functional new grandstand seats. The brand will keep providing cost-effective, long-service-life overall seating solutions for national fitness venues and cultural tourism performance projects, boosting the high-quality upgrading of domestic sports infrastructure.
