The Model 200 bridge adopts a through-type steel truss structure, with the main truss units featuring a Warren (or "double-Warren"/"K-type") truss configuration. The top and bottom chords, vertical members, and diagonal members are all fabricated from channel steel, pre-welded in a factory setting, eliminating the need for on-site welding.
Standard roadway widths are configured as 3.15 meters, 4.2 meters, and 7.35 meters. This bridge type is suitable for emergency access routes, basic transportation infrastructure, pipeline support, and strategic emergency reserves.
