Overview
The Bold bridge is a modular pedestrian bridge system combining architecturally detailed posts with multiple balustrade and decking options. Standard materials include Corten steel or hot-dip galvanised steel, with optional powder coating in RAL Classic colours. Balustrade infill choices include horizontal stainless steel cables with tensioners, stainless steel cable mesh, or Corten expanded metal. Handrail options: oval-planed hardwood handrail or stainless steel tubular handrail (Ø 10 cm). Decking can be executed in Cordeck®40; optional anti-slip dots can be applied to the profiles.
