Weld-Free and Worry-Free: Redefining Structural Efficiency in High-Seismic Regions

图片
 For contractors weary of labor-intensive, time-consuming structural installations—especially in high-seismic zones— bolted steel framing offers a solution that radically redefines safety standards. Its core advantage? A design that guarantees ease of assembly without sacrificing seismic performance, streamlining on-site workflows while meeting every compliance requirement. The days of project delays caused by on-site welding, tedious alignments, or bulky reinforcement are over. Bolted steel components are prefabricated, precision-cut, and pre-drilled, ready for assembly straight off the truck. The intuitive bolting system requires no specialized skills for installation, allowing crews to erect frames with rapid precision, significantly cutting down installation time compared to rigid structures like concrete. No more worrying about mismatched parts or labor-heavy phases—this system is built for high-speed execution, even under the toughest site conditions. But simplicity doesn’t ...

Welded ball processing method

  Welded ball Hot press moulding method Unloading: according to the design requirements, adopt semi-automatic gas cutting, profiling gas cutting, CNC flame gas cutting and other methods to unload the steel plate and cut out the round plate of suitable size, when unloading, it is necessary to reserve the welding shrinkage margin for fabrication and installation as well as the machining margins for cutting, edge planing, milling and so on. Heating: The blanks are heated uniformly to about 1050 ° C ± 50 ° C in a reflector furnace or resistance furnace after unloading. Pressing and moulding: Use hydraulic presses and matching convex and concave moulds to press and mould the heated slabs to produce hemispherical shapes. The demoulding temperature should not be lower than 650 ° C. After the hemisphere is pressed and moulded, the wall thickness should be reduced by not more than 13% and not more than 2.5mm according to the design and specification. Cutting bevel margin: can be processe...
