Component Specifications

Definition
The intermediate rail is a horizontal structural member installed between the top handrail and bottom kickplate in handrail systems. It serves as a secondary safety barrier, prevents climbing or falling through openings, and provides additional support for users. In industrial applications, it must withstand mechanical stresses, environmental conditions, and comply with safety regulations regarding height, spacing, and load capacity.
Working Principle
The intermediate rail functions as a load-distributing structural element that transfers forces from impact or pressure to the supporting posts and framework. It creates a barrier system that limits passage through openings while maintaining visibility and accessibility. Its installation follows specific height requirements (typically 450-600mm from walking surface) to prevent falls and ensure ergonomic safety.
Materials
Typically manufactured from: 1. Stainless steel (AISI 304/316, 1.5-2.0mm thickness), 2. Aluminum alloy (6061-T6, 2.0-3.0mm thickness), 3. Galvanized steel (S235JR, 1.8-2.5mm thickness with zinc coating ≥80μm), 4. Powder-coated mild steel (S355JR, 2.0-3.0mm with epoxy-polyester coating)
Technical Parameters
  • clearance_gap ≤100mm between rails
  • load_capacity ≥1500N concentrated load
  • diameter_range 42.4-48.3mm
  • wall_thickness 1.5-3.0mm
  • height_position 450-600mm from walking surface
  • standard_length 2000-6000mm
  • deflection_limit ≤L/200 under load
Standards
ISO 14122-3, DIN EN ISO 14122, OSHA 1910.23, BS EN 14122-3

Frequently Asked Questions

What is the standard height for intermediate rails in industrial applications?

According to ISO 14122-3 and OSHA standards, intermediate rails should be installed at 450-600mm above the walking surface to prevent falls while maintaining visibility.

Can intermediate rails be used as handrails?

No, intermediate rails are not designed as primary handrails. They serve as mid-level barriers to prevent falls through openings, while top rails (at 1000-1100mm) function as proper handrails.

What materials provide the best corrosion resistance for intermediate rails?

Stainless steel AISI 316 offers superior corrosion resistance for harsh environments, while hot-dip galvanized steel provides excellent protection at lower cost for most industrial applications.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
