Successful Completion of TÜV Load-Bearing Test for 550mm×1500mm Heavy-Duty Aluminum Truss

This week, GF-Truss invited TÜV SÜD, a globally authoritative certification body, to conduct a professional load-bearing test on our 550mm×1500mm heavy-duty aluminum truss, covering four spans: 10m, 20m, 30m and 40m. To ensure data accuracy, professional technicians completed preliminary mechanical simulation calculations based on the truss specifications and structure before the on-site load test. During the official test, the technical team accurately marked the truss loading points, adopted the method of uniformly applying the target load at one time, recorded the truss deflection after one hour of standing, and strictly followed TÜV SÜD test standards throughout the process.

Test Procedure and Methodology

The on-site load-bearing test was conducted under a clearly defined and controlled procedure:

• Preliminary mechanical simulation calculations based on truss specifications and structure
• Every loading point on the truss was accurately marked. This step was crucial to ensure we applied the load precisely where it needed to be.
• Uniform application of the target load in a single loading phase
•  After an hour under full load, we took careful measurements of deflection to assess the performance of the structure.
• Full compliance with TÜV SÜD testing standards throughout the entire process

All test operations were witnessed and evaluated by TÜV SÜD experts to ensure consistency with applicable certification requirements.

Field Test Proves Strength: Impressive Full-span Load Data Exceeds Expectations

Online mechanical simulation showed that the ideal uniform load capacity of the 40m-span truss is 6500KG. In the on-site test, the technical team evenly distributed 9750KG across 10 loading points, with the truss deflection only reaching 270mm, well within the safety threshold. Further targeted tests yielded more convincing data: for the 40m-span truss, deflection was 110mm under 2000KG central load and also 110mm under 6000KG four-point load.

Drawing on the mature experience from the 40m test, the 30m-span truss test proceeded efficiently. With 12000KG evenly distributed across 12 loading points, deflection was 130mm; it measured 67mm under 4000KG central load and 97mm under 8000KG four-point load, all meeting safety standards. The full-span test results fully demonstrate the excellent load-bearing capacity and structural stability of the trusses.
