Post/Upright: Diameter 42.4mm (standard tube)

Component Specifications

Definition

A critical load-bearing component in handrail systems that transfers vertical and lateral forces from handrails to machine frames or foundations. Designed to withstand operational stresses, vibrations, and environmental factors while maintaining precise alignment and safety compliance.

Working Principle

Acts as a rigid column that resists compressive, bending, and torsional loads through its geometric design and material properties. Distributes forces from handrails evenly to mounting points while maintaining dimensional stability under dynamic conditions.

Materials

Typically carbon steel (ASTM A36/A500), stainless steel (304/316), or aluminum alloy (6061-T6). Surface treatments include hot-dip galvanizing, powder coating, or anodizing for corrosion resistance.
