Products classified under HTS 7308.10.00.00
Welded Steel Box Girder Bridge Segment
Hollow box girder segment fabricated from steel plates via submerged arc welding for highway overpasses. HTS 7308.10.00.00 applies as a prepared bridge section of steel for structural use. Provides torsional rigidity in modern bridge designs.
Steel Truss Bridge Section
A prefabricated section of a truss bridge made from welded steel I-beams and cross-bracing, designed for assembly into pedestrian or vehicular bridges. It falls under HTS 7308.10.00.00 as a bridge section of iron or steel, specifically prepared for structural use in bridge construction. These sections are transported to sites for bolting or welding into complete bridges.
Prefabricated Steel Arch Bridge Span
A curved steel arch span module for arch bridges, constructed from high-strength steel plates and tubes, ready for on-site connection. Classified under HTS 7308.10.00.00 as a bridge section due to its specific design for spanning rivers or valleys in iron or steel structures. Includes integral joints for modular assembly.
Iron Bailey-Type Bridge Panel
Modular cast iron panel from Bailey bridge systems, featuring pin connections for rapid deployment in military or temporary bridges. It qualifies for HTS 7308.10.00.00 as a bridge section of iron, historically used in WWII and still for emergency structures. Panels interlock to form roadway decks.
Steel Suspension Bridge Cable Saddle
A massive forged steel saddle for anchoring main cables on suspension bridges, machined to fit cable diameters. Under HTS 7308.10.00.00 as a specialized bridge section/part of iron or steel structures. Distributes load from cables to towers.
Steel Railway Bridge Girder
I-shaped steel girder engineered for railway bridges, with rail-bearing top flange. Classified HTS 7308.10.00.00 as bridge section for iron/steel structures supporting train loads. Includes shear studs for concrete deck composite action.
Modular Steel Pedestrian Bridge Deck
Prefabricated deck panel with non-slip steel grating for pedestrian footbridges. Falls under HTS 7308.10.00.00 as a bridge section of steel, complete with handrail attachment points. Lightweight design for urban park installations.
Steel Swing Bridge Pivot Pier Section
Cylindrical steel pier section with live-load ring for swing bridges that rotate for vessel passage. HTS 7308.10.00.00 for bridge sections of steel in marine environments. Houses pivot bearings.
High-Strength Steel Bridge Tower Segment
Tapered steel segment for cable-stayed bridge towers, bolted construction with internal access. Under HTS 7308.10.00.00 as bridge section though tower-like, due to integral bridge function. Weather-resistant alloy steel.
Corrosion-Resistant Steel Bridge Abutment
Steel abutment frame with bearing seats for beam ends at bridge approaches. Classified HTS 7308.10.00.00 as bridge section of steel, galvanised for soil/road salt exposure. Transfers loads to foundations.
