Passive Protection. Always On.
Engineered guardrail systems for floor edges, roof perimeters, and elevated platforms — compliant with OSHA 1926.502(b) and DOLE DO-13.
What Guardrail Systems Do
Guardrail systems are passive fall protection — they require no action from the worker to be effective. A properly engineered guardrail prevents workers from reaching the fall hazard in the first place. Under OSHA 1926.502(b), top rails must withstand 200 lbs of force in any direction; mid-rails must withstand 150 lbs. Our systems exceed these minimums and are designed for Philippine tropical conditions including wind loading and corrosion resistance.
Components
System Components
Top Rail
42 inches (±3 in.) above walking surface. Minimum 200 lb load capacity in any direction. Galvanized steel pipe or powder-coated aluminum.
Mid Rail
Positioned midway between top rail and walking surface. Minimum 150 lb load capacity. Required when there is no wall or parapet.
Toe Board
Minimum 3.5 inches high. Prevents tools and materials from rolling off edges. Required where workers pass below.
Posts / Uprights
Spaced maximum 8 feet apart. Anchored to structural slab or beam — never to formwork alone. Load-tested anchorage design.
Intermediate Members
Screens, mesh, or intermediate rails where opening exceeds 19 inches. Prevents workers from falling through.

Load Design Basis
| Load Type | OSHA Requirement | Our Design |
|---|---|---|
| Top Rail Horizontal | 200 lbs (890 N) at any point | 250 lbs minimum — 25% safety margin |
| Top Rail Vertical | 200 lbs (890 N) downward | 250 lbs minimum |
| Mid Rail | 150 lbs (667 N) any direction | 200 lbs minimum |
| Post Anchorage | Resist all applied rail loads | Structural calculation per NSCP wind + live load |
| Wind Load | Per NSCP 2015 Chapter 2 | Site-specific wind zone analysis included |
Installation
Installation Timeline
Day 1
Site survey, edge mapping, anchorage point identification and structural verification
Day 1–2
Post installation and anchorage — core drilling or cast-in sleeve placement
Day 2–3
Rail installation, mid-rail and toe board fitting
Day 3
Load testing, inspection, and documentation
Ongoing
Monthly inspection, damage reporting, and replacement of compromised components
Maintenance
Maintenance Schedule
Daily
Visual inspection before each shift — check for damage, displacement, or missing components
Weekly
Check all post anchorages for loosening; verify toe boards are secure
Monthly
Full documented inspection by safety officer; load test sample anchorages; check for corrosion
After Impact
Remove from service immediately; inspect all components; replace any deformed or cracked members before reinstalling
End of Project
Full disassembly inspection; refurbish or retire components per manufacturer guidelines
