Need a frame that's strong but not heavy, and saves material costs? Our open-web type steel spatial frame is the solution. It brings efficient support to industrial workshops, logistics centers, and large-span warehouses-with hollow-core structure that cuts weight while maintaining load capacity. Perfect for projects chasing both structural performance and cost-efficiency.
Key Features & Material:
Made of high-strength Q355/Q460 structural steel, its open-web (hollow) components are CNC-cut and robot-welded for precision. The frame gets hot-dip galvanizing + fluorocarbon coating for anti-corrosion. The hollow design reduces material use, and the integrated structure allows quick assembly-only annual visual inspections are needed.
