Heavy Duty Welded Steel Plate Girder Bridge

To prepare an accurate engineering and commercial proposal for a heavy duty welded steel plate girder bridge, KXD’s structural team requires the following information: clear span length and number of spans; design live load class (vehicle axle configuration, lane load model, or rail load class); applicable design standard (AASHTO, EN 1993, or national equivalent); required road or rail clearance; site environment class (for corrosion protection specification); and any third-party inspection or certification requirements. Preliminary site survey data, geotechnical report summaries, or authority-issued design briefs are welcomed at the enquiry stage.

Yes. KXD’s in-house structural engineering team designs bridge structures to client-specified standards including AASHTO LRFD, EN 1993 Eurocode 3, and equivalent national design codes as required by the project authority or financing institution. Full structural calculation reports, load model documentation, and design drawings are provided as part of the engineering deliverable package. If the applicable standard is not confirmed at the enquiry stage, KXD’s engineers will advise on the most commonly accepted standard for the project’s country of installation.

KXD’s bridge fabrication process is fully open to witness inspection by internationally recognised agencies including Bureau Veritas (BV), SGS, and ITS. Inspection hold points can be incorporated into the fabrication quality plan at weld inspection, dimensional check, surface treatment, and final despatch stages. For development bank-funded projects or government procurement contracts that mandate independent quality verification, KXD’s quality management system — certified to ISO 9001:2015 and CE EN1090 — is structured to support these requirements without requiring special process modifications.

The standard fabrication and delivery timeline for KXD’s prefabricated steel bridge products is 60 days from drawing approval and order confirmation. This timeline covers factory fabrication, surface treatment, inspection, packaging on steel pallets suitable for overseas container shipment, and port delivery. For multi-span programmes or projects requiring accelerated scheduling, production capacity and timeline should be confirmed at the enquiry stage. KXD’s monthly bridge supply capacity of 3,000 tons supports concurrent fabrication of multiple bridge units within a single production cycle.

Yes. KXD can dispatch qualified erection supervisors to the project site to guide local crews or directly manage the structural assembly process for bridge installation. The scope of on-site supervision — including the number of supervisors, duration of site attendance, and technical responsibilities — is confirmed at the project planning stage based on bridge complexity, local labour capability, and contract requirements. Where the project requires welded field connections, KXD can also provide the relevant WPQR documentation and welding procedure supervision to support site quality control.
