SAFS Steel Structure Space Frame Truss

 Welding is the backbone of steel grid frame stability. Here’s how professionals control welding quality: Certified Welding Processes: Use GMAW (Gas Metal Arc Welding) or SAW (Submerged Arc Welding) per AWS D1.1 or ISO 3834. Non-Destructive Testing (NDT): Ultrasonic Testing (UT): Detects internal weld flaws like inclusions. Magnetic Particle Testing (MT): Spots surface cracks. Radiographic Testing (RT): Confirms internal fusion integrity. Strict QA/QC Processes: All welds logged, sampled, and verified by third-party inspectors before proceeding with assembly. Poor welds = costly repairs and structural risk. Most users concerned with “steel structure failures” ask how to avoid welding faults — this is the answer. ✅ Want to know how we reduce onsite welding to <5% of total joints?

Steel grid frame (also known as space frame) structures are becoming increasingly popular for logistics centres, sports stadiums and factory buildings for several reasons: Large spanning capacity: steel grid frames can cover large areas (50 metres or more) without the need for internal columns, maximising the available space. Lightweight and high strength: Steel tubes and nodes provide high load-bearing capacity with minimal material. Modularity and rapid assembly: Components can be prefabricated and assembled on site, reducing construction time by 30-50%. Design Flexibility: Triangular, rectangular or hybrid grids can be used to customise roofs, domes and facades. Many users looking for ‘large-span roofing alternatives’ and ‘cost-effective warehouse design’ find that steel grid frames offer these benefits and are ideal. 💡 Have you used space framing in your projects? Please provide your experience or a real-world case study.

Net frame installation is one of the most critical stages in the whole project, especially in the construction of high altitude or large span venues, where risks and challenges exist. Installation key points of attention: Measuring and placing lines must be accurate: errors can cause the whole structure to be docked out of place.  Clear component numbering and safe transport: large components often need to be transported in sections, and on-site assembly to the right number is key.  Welded nodes should not have concentrated stress: buffer design should be adopted to avoid deformation or cracks caused by thermal stress.  Work-at-height safety: wear safety belts and use standard scaffolding and lifting equipment.

Welding quality directly affects the safety and service life of the mesh frame structure . In order to ensure the welding quality, it is usually controlled from the following aspects. Weld inspection technology: Ultrasonic flaw detection (UT): to find out the internal defects of the weld, such as unfused and porosity.  Magnetic particle testing (MT): for detecting minor defects such as surface cracks.  Radiographic testing (RT): in-depth inspection of the internal integrity of the weld by X-rays.  Welding quality control process: Strictly control the qualification of welders.  Clearly defined Welding Process Specification (WPS).  Each process is accepted by quality control personnel to avoid rework.  Use double testing for critical parts. If you have encountered welding technical problems in large-scale steel structure projects, welcome to leave a message, our experienced team is willing to provide solution suggestions and service programmes.

Steel grid is gaining more and more attention in green buildings, mainly because of its environmental and sustainable advantages: High strength and light weight: The grid structure can cover the space with a large span, reduce the use of columns, improve the efficiency of building space, and save materials. Recyclable: 100% of steel is recyclable and reusable, which is in line with the core concept of "sustainability" of green buildings. Short construction period: The components are prefabricated in the factory and installed quickly on site, which effectively reduces dust and noise pollution and has little impact on the surrounding environment. Strong compatibility with solar energy/green roofs: Steel structures are easy to integrate green building technologies such as solar panels and rainwater collection.

 The steel structure bolted ball connection realises the welding-free assembly of the mesh frame nodes through the precision cooperation of the built-in cone head, socket and high-strength bolts, which significantly improves the construction efficiency and stability of the structure, and is especially suitable for large-span space structures. The core principle of the bolt ball node is based on the mechanical transmission path: the tension is transmitted through the steel pipe → cone head → high-strength bolt → steel ball, and the pressure is dispersed to the ball through the sleeve. Its design needs to meet the limitations of ball diameter ≤ 300mm, bolt specification ≤ M64 and other parameters to ensure the node bearing capacity and seismic performance. The co-ordination between the built-in cone head and the sleeve can avoid the weld quality defects caused by the welding of the traditional external cone head, and at the same time reduce the on-site installation errors.

 In the net frame structure building, steel structure bolt and ball connection has a key application method by virtue of its unique structure and performance advantages, which has a significant impact on the stability and construction efficiency of the building. From the mechanical theory, the bolt ball connection uses high strength bolts to fasten, which can effectively transfer the tension and pressure between the rods, and through the reasonable design of bolt specifications and ball node size, it fits the stress characteristics of the net frame structure and guarantees the overall mechanical properties. A large sports stadium adopts net frame structure, using bolt ball connection. During the construction, the standardised bolted balls and rods accelerated the installation process, and after long-term use and monitoring, the structure was stable and there was no problem of connection failure. In the case of a grid structure with bolted ball connections, how do you think the con...
