As global sports facility construction continues to evolve toward higher levels of professionalism, safety, and multifunctionality, the structural safety, load-bearing capacity, and long-term performance of spectator seating systems have become increasingly important considerations in stadium construction projects.
For electric retractable bleachers, structural stability under different loading conditions is just as important as the flexibility and space-saving benefits they provide. Reliable platform performance plays a key role in supporting the safe and practical operation of modern sports venues.
EN 13200-6:2020: An Important Standard within the European Spectator Facility Standards Framework
EN 13200 is a European standards series covering spectator facilities, providing technical requirements and guidance for spectator seating facilities in sports venues and other public facilities.
EN 13200-6:2020 is Part 6 of this series, titled Spectator Facilities – Part 6: Demountable Stands. It addresses technical requirements related to demountable spectator stands.
This standard provides a technical reference for the design and evaluation of spectator stand structures and their performance. The specific clauses referenced in this test include:
● Clause 5.4.3 – Imposed Vertical Loads: Distributed loading tests evaluate the platform's deformation under uniformly applied loads and its residual deformation after the loads are removed.
● Clause 5.4.4 – Isolated Loads: Concentrated loading tests assess the platform's structural response and deformation when a load is applied to a specified local area.
These two test methods examine platform performance under both overall and localized loading conditions, providing important reference data for structural design and quality verification of spectator stands.
Electric Retractable Bleacher TUV Test Report
SMART GROUP Receives TÜV SÜD Third-Party Test Report for Electric Retractable Bleachers
At SMART GROUP, we place great importance on applying international standards and relevant testing requirements throughout product development, manufacturing, and quality verification.
In May 2025, SMART GROUP's independently manufactured electric retractable bleachers, Model BL-STE, underwent third-party load testing conducted by TÜV SÜD Certification and Testing (China) Co., Ltd., Guangzhou Branch. The test report was issued on May 28, 2025, under Report No. 64.190.25.0229.01-00.
The testing was conducted with reference to the relevant clauses of EN 13200-6:2020 and covered two main test items:
1. Distributed Loading Test
During the test, a uniformly distributed load of 1,500 kg was applied to a stand platform with an area of 2.7 m². The platform deformation was measured according to the specified testing procedure.
The results recorded a deflection of 4 mm under loading and a residual deflection of 0 mm after the load was removed.
2. Concentrated Loading Test
For the concentrated loading test, a load of 150 kg was applied to a designated area of the stand platform using a 0.2 m × 0.2 m loading plate.
The test results also recorded a deflection of 4 mm under loading and a residual deflection of 0 mm after unloading.
These results document the structural deformation performance of the submitted sample under the specified loading conditions, providing third-party test data for evaluating the platform's load-bearing performance.
Applying International Standard Requirements to Strengthen Product Quality Management
For SMART GROUP, third-party testing is not only an important part of product performance verification but also a valuable reference for continuously improving product development and manufacturing processes.
The company incorporates applicable load-testing requirements referenced in EN 13200-6:2020 into the structural design and quality verification of relevant products. Particular attention is given to platform structures, load-bearing performance, and manufacturing quality control to address the practical requirements of different sports facilities.
As a professional sports facility solutions provider, SMART GROUP offers more than electric retractable bleachers. Its product portfolio also includes steel grandstands, aluminum alloy bleachers, stadium seats, and other spectator facility products for sports stadiums, school gymnasiums, multipurpose halls, and commercial venues worldwide.
Moving forward, SMART GROUP will continue to follow relevant international industry standards and third-party testing requirements while improving product development, structural design, and manufacturing quality management.
Through ongoing investment in product quality and engineering capabilities, SMART GROUP aims to provide global customers with professional, reliable, and project-oriented sports seating and grandstand solutions.
