Heat treatment process parameters must be strictly determined according to the material properties, thickness and welding method of the photovoltaic steel structure.
The transportation integrated bracket, a comprehensive support structure integrating multiple functions, is becoming a key solution to the challenges of multi-disciplinary pipeline layout in subway tunnels. Through system integration and collaborative des
Metal materials such as austenitic stainless steel have significant linear expansion coefficients at low temperatures, and the amount of shrinkage increases as the temperature decreases.
Through system integration, modular design, BIM collaboration, and standardized construction, the building integrated bracket transforms mechanical and electrical installation from a "piecemeal" operation to a "systematic engineering" approach.
If the node welds of the portal steel frame structure have quality problems such as incomplete penetration, slag inclusions, cracks, and undercuts, the effective load-bearing capacity of the welds will be greatly weakened.
During long-term use, the stability of the photovoltaic steel structure can be maintained through regular maintenance.
