Railway steel structure bridge

Zhengcheng is a steel structure manufacturer and project service provider based in Shandong, China. We focus on customized steel structure buildings and fabricated steel components for industrial plants, warehouses, workshops, livestock buildings, parking structures, bridges, and overseas project applications. What makes us different is not only production capacity, but the way we support the whole project. Our factory team can handle steel cutting, welding, drilling, surface treatment, component marking, packing, and loading, while our engineering and service team helps review drawings, confirm technical details, control quality, and support installation communication after delivery. Before production, we help you clarify the scope, materials, standards, coating, packing method, and delivery schedule. After shipment, we continue to provide drawing support, installation guidance, and timely communication when your site team needs help.

We control quality from drawing review to final shipment, not only at the last inspection stage. Before production, our engineering team helps check drawings, material grades, dimensions, connection details, welding requirements, surface treatment, and packing needs. During fabrication, our factory team controls cutting, welding, drilling, assembly accuracy, bolt-hole position, component marking, and anti-corrosion treatment. Before shipment, we inspect the finished steel members, confirm quantities, check packing lists, take photos when needed, and arrange loading carefully to reduce damage and missing parts. For overseas projects, our service team can continue to support installation communication after delivery, including drawing clarification, component identification, and technical coordination when your site team needs help.

We supply customized steel structure buildings and fabricated steel components for overseas projects, including workshops, warehouses, industrial plants, multi-storey steel buildings, livestock houses, parking garages, bridge components, Bailey bridges, grid steel structures, villas, stairs, platforms, pipe racks, and related steel parts. Zhengcheng is not only a product supplier. Our factory team can handle cutting, welding, drilling, surface treatment, marking, packing, and loading, while our engineering and service team helps review drawings, confirm materials, control quality, and support installation communication after delivery.
