Steel truss pedestrian bridges
Through and deck trusses for medium spans, built from segments that are practical to transport and splice on site.

评分是基于典型范围的简单参考。结构体系必须由项目工程师确定。
Pony truss pedestrian bridges
Half-through trusses without overhead bracing: an open, economical option for short to medium spans.
Steel girder pedestrian bridges
Rolled or plate girders with few members: a direct, low-maintenance solution for short spans.
Steel box girder pedestrian bridges
Closed steel sections for curved alignments, clean appearance and good torsional stiffness.
Steel arch pedestrian bridges
Deck or through arches for landmark crossings where appearance matters as much as span.
Tied arch pedestrian bridges
The deck ties the arch ends together, so foundations carry mainly vertical load.
Cable-stayed and suspension footbridges
For long spans and signature crossings, with the steel deck carried by stays or hangers.
Covered and enclosed pedestrian bridges
Skywalks and link bridges with roofs, glazing or cladding for weather protection.
Modular and prefabricated pedestrian bridges
Repeatable modules, bolted assembly and short installation times for trails, parks and temporary crossings.
