Foundation pit guardrail

Foundation pit guardrail is an important safety facility for edge protection in construction, mainly used in:

✅ Construction foundation pit: prevent personnel and materials from falling, ensure construction safety

✅ Subway/tunnel engineering: isolate excavation areas to avoid accidental collapse risks

✅ Municipal road construction: warn pedestrians and vehicles, reduce hidden dangers outside the construction site

✅ Pipeline trench protection: protect the safety of deep pit workers
