Zhong Sheng Jia He provides comprehensive EPC (Engineering, Procurement, Construction) general contracting services for steel structure projects, covering the entire process from project planning, schematic design, detailed design, material procurement, factory fabrication, logistics transportation, on-site construction, system commissioning, to final acceptance—delivering a true integrated turnkey solution with full-cycle management.
As an integrated steel structure building system service provider, we hold Class II General Contracting qualification, Class II Steel Structure Contracting qualification, as well as specialized licenses in foundation works, waterproofing and anti-corrosion, finishing, special engineering, and formwork scaffolding.
This enables us to independently undertake steel structure projects from underground foundations to above-ground structures, from structural construction to envelope systems.
We engage from the early project stage, conducting site surveys, load calculations, seismic analysis, fire protection and anti-corrosion design, assisting clients with feasibility assessments and permitting approvals to ensure the project is scientifically sound and executable from the outset.
We utilize BIM 3D modeling technology for structural system selection and modular combination design, generating 3D solutions within 2 hours. During the detailed design phase, we complete shop drawing detailing and connection node design, delivering precision ±1mm shop drawings and complete bills of materials, ensuring seamless integration between design and fabrication.
We maintain a rigorous supplier management and material traceability system, overseeing the entire process from steel material execution, raw material input, steelmaking, chemical testing, to factory delivery. Through bulk procurement and cost control mechanisms, we effectively manage procurement costs while ensuring material quality.
Supported by our 15,000㎡ self-owned manufacturing base, we have an annual steel structure production capacity of 20,000 tons. We utilize digital production equipment for CNC cutting, automated welding, and intelligent processing. All components undergo 100% quality inspection before leaving the factory, achieving a welding pass rate of over 99%. Each component is traceable throughout its lifecycle via QR codes.
Components are packaged with anti-rust packaging meeting international shipping standards and container loading solutions. We manage the entire transportation process including domestic land transport, international sea freight, and final-mile land transport. Our "menu-style" delivery strategy ensures components are shipped in batches according to hoisting zones and delivered precisely according to the construction sequence, eliminating on-site stockpiling and secondary handling.
We dispatch professional technical teams to site, utilizing high-strength friction-type bolt connections as the primary method to minimize on-site welding, improving installation efficiency by over 30%. For large-span structures, we employ hydraulic synchronous lifting and integral hoisting technologies, combined with BIM, drone inspection, and 3D scanning to achieve millimeter-level visual control throughout the installation process.
We complete system commissioning for electrical, HVAC, fire protection, and other systems, conduct structural safety testing and non-destructive weld testing, and organize sub-item acceptance and final project acceptance, ensuring the project meets design requirements and functional specifications.
We deliver BIM as-built models, maintenance manuals, and complete acceptance documentation to clients, providing warranty repair services during the defect liability period, periodic site visits, and long-term technical support.
The EPC model establishes a single point of responsibility, allowing clients to interface with only Zhong Sheng Jia He from concept to completion. With our design-led approach, we control over 80% of total project costs during the early planning and design stages. Through the integrated approach of value engineering, bulk procurement, prefabricated construction, and refined management, we deliver the "Three Savings" value—controllable quality, predictable schedule, and manageable cost—giving our clients peace of mind, time savings, and cost efficiency.
Zhong Sheng Jia He's products and services have been successfully delivered across Southeast Asia, Africa, and other overseas markets, accumulating extensive international project execution experience. We are capable of executing projects to GB (Chinese), AISC (American), EN (European), and ASEAN local standards, meeting the design codes and certification requirements of different countries. For export support, we provide anti-rust packaging meeting international shipping standards, end-to-end sea-land multimodal transport management, and customs clearance support for various countries. For overseas installation, we dispatch professional technical teams to site, providing installation guidance and construction services to ensure successful delivery of international projects.
Whether for industrial plants, commercial landmarks, sports venues, convention centers, public facilities, or modular buildings, Zhong Sheng Jia He delivers professional, efficient, and reliable steel structure turnkey solutions through our EPC model.
