A decking handrail/balustrade system is composed of several key components, each serving both structural and aesthetic purposes. Here’s a breakdown of typical decking handrail components:

• Size: 1.5m x 82mm x 82mm

2. Top Rail (Handrail)

• Purpose: Provides a gripping surface and ties the railing system together.

• Size: 3.6m x 78mm x 33mm

3. Bottom Rail

• Description: Horizontal rail running along the bottom of the balusters or infill.

• Purpose: Holds balusters in place and provides additional structural support.

• Size: 3.6m x 78mm x 38mm

4. Spindles

• Description: Vertical infill pieces between the top and bottom rails.

• Spacing: Must not allow a 100mm sphere to pass through (per most building codes).

• Style: Square

• Size: 0.900m x 42mm x 42mm
