As prefabricated construction technology continues to evolve, aluminum alloy guardrails have transcended their role as simple

 enclosure components to become comprehensive, high-tech protective systems integrating profile fabrication, surface treatment, 

structural engineering, and standardized installation.

The system eschews traditional welding and threaded connections in favor of a rapid, snap-fit assembly design. Posts, horizontal 

rails, vertical balusters, and handrails undergo precision cutting and machining in the factory; handrails are secured to walls using 

aluminum die-cast brackets and internal expansion bolts, while posts are anchored to the floor using aluminum connectors and

 internal expansion bolts—standardized connectors that ensure the structural stability of connection points. Regarding design 

specifications, standards mandate a handrail height of 900–1200 mm above the floor, with post spacing capped at 1200 mm for

 standard guardrails and 1000 mm for glass guardrails; vertical baluster spacing is limited to under 110 mm to prevent entrapment

 hazards. Profile wall thicknesses are determined by load requirements—≥1.2 mm for horizontal rails and ≥1.0 mm for vertical 

balusters—with increased thickness in high-stress areas to meet the structural requirement of withstanding a uniformly distributed 

load of ≥1000 N/m.
