TKDNsteelbuilding has specialized in steel structure manufacturing for years. We recently finished full prefabrication, precision processing and sectional integrated shipment of steel box girders for Xinzheng Bridge project. Equipped with self-owned intelligent production lines, we provide integrated steel structure delivery services for global infrastructure and industrial clients, covering three core product lines: steel warehouse buildings, steel structures, prefabricated steel bridge structures.
Prefabricated steel bridges are our key engineering product series. The Xinzheng bridge steel box girders are made of Q355 high-strength steel plates. All processes including CNC cutting, automatic submerged arc welding, integral sandblasting and anti-corrosion treatment are completed in factory. After sectional fabrication, girders are reinforced and packed uniformly for standard truck shipment, greatly cutting on-site construction time. Compared with cast-in-place bridges, prefabricated steel box girders feature light weight, superior torsion and bending resistance, ideal for urban interchanges, river-crossing bridges and viaducts with stable performance and low long-term maintenance cost.
Besides bridge components, TKDNsteelbuilding mass-produces standard steel warehouse buildings and diversified steel structures, including portal frame workshops, logistics storage warehouses and multi-story steel commercial buildings. All structural parts are prefabricated in factory then packed for unified shipment, realizing one-stop service covering design, production, anti-corrosion and logistics. Unified production standards and standardized packaging & shipment system enable efficient simultaneous delivery of bridge box girders and factory steel components, cutting clients’ total purchasing and transportation expenses.
The Xinzheng bridge steel box girder project fully proves the high precision and efficiency of factory prefabrication. Whether large-scale prefabricated steel bridge projects, medium & small steel warehouse buildings or commercial steel structures, TKDNsteelbuilding offers customized design, mass production and full truck loading shipment. We support global sea and land export, complete drawing sets, quality inspection certificates and on-site installation guidance. Engineering contractors and infrastructure purchasers worldwide are welcome to contact us for cooperation.
