Core Strengths
Our scale, precision, and technological superiority ensure we deliver on multi-million dollar international contracts with absolute certainty.
Factory-Based Manufacturing
We have our own steel structure production system, supporting cutting, welding, drilling, assembly, surface treatment, component marking, packing, and loading. This helps us control fabrication quality and delivery details from the source.
Engineering & Drawing Support
Before production, our engineering team can help review drawings, confirm material grades, check connection details, and clarify technical requirements. We help you reduce unclear scope before steel members enter fabrication.
Quality Control Process
We pay attention to material preparation, welding quality, bolt-hole accuracy, dimensional control, coating treatment, component marks, packing lists, and pre-shipment inspection. Every detail matters when the goods need to be installed overseas.
Overseas Project Service
Jingcheng specializes in serving the overseas market and offers a one-stop solution for overseas users. When your on-site team needs assistance, we will provide you with 24/7 service throughout the process, including but not limited to providing drawing explanations, installation communication, component identification, and technical coordination, etc.
