1. Project Basic Information (Quantified Core Data)
Project Location: Overseas coastal industrial zone
Building Area: 28,600 ㎡ heavy industrial workshop
Total Steel Consumption: 1,680 tons heavy steel structure
Structure Type: Large-span rigid frame heavy steel structure with overhead crane load system
Delivery Cycle: 75 days full-cycle production + 25 days on-site installation guidance
Compliance Standard: Fully certified by AISC (US), EN1090 (EU CE), CSA (Canada), 100% compliant with local coastal building safety, wind resistance and anti-corrosion codes
2. Customer Core Pain Points
The overseas general contractor faced multiple technical and schedule bottlenecks before cooperation. First, the large-span workshop requires super heavy load-bearing capacity for industrial overhead traveling cranes, bringing strict structural strength and stability challenges. Second, the coastal high-salt and high-humidity environment causes severe steel corrosion risks, demanding long-term anti-rust and anti-corrosion performance. Third, the local construction codes and international standard certification thresholds are extremely strict, making standard matching and document approval difficult. In addition, the project had an extremely tight construction schedule with zero delay tolerance. Meanwhile, the customer lacked professional steel structure drawing deepening and BIM optimization capabilities, resulting in repeated revision risks and low construction efficiency.
3. Customized One-Stop Engineering Solution
We delivered a full-link customized solution integrating design, production, anti-corrosion treatment and overseas technical guidance to solve all customer pain points. Adopting Q460 high-strength heavy steel material, it greatly improves overall structural rigidity and meets ultra-large-span heavy-load operation requirements. Professional BIM 3D modeling and structural finite element analysis optimize the overall force distribution, eliminate structural design defects and complete full set of drawing deepening and standard filing. Equipped with professional coastal heavy-duty anti-corrosion coating system to adapt to harsh marine climate. Supported by fully automated CNC production lines, we realize high-precision component manufacturing. We also provide whole-process overseas on-site installation guidance and standard technical docking services, ensuring full compliance with local international codes.
4. Production & Delivery Implementation Process
All steel components adopt standardized industrial production procedures: precise CNC cutting, automatic robotic welding, professional weld flaw detection, heavy-duty shot blasting rust removal and multi-layer high-performance anti-corrosion painting. All production processes strictly follow AISC, EN1090 and CSA standard specifications, with complete quality inspection records and certification documents. After finished production, standardized container loading and whole-process tracked sea transportation are adopted to ensure intact delivery of all steel components to the overseas construction site, supporting rapid on-site assembly.
5. Final Project Completion Effect
The project has been fully completed and officially put into operation. The overall steel structure is stable and firm, with perfect large-span flatness and no structural deformation. The internal heavy-load crane system operates stably and meets long-term industrial production load requirements. The exterior anti-corrosion coating is uniform and flat with excellent weather resistance. Aerial panoramic view shows neat and standardized overall construction effect. All structural indexes, safety performance and energy-saving indicators fully meet local official acceptance standards and international engineering specifications, achieving zero safety hazard and zero quality defect acceptance.
6. Core Cooperation Value
This one-stop steel structure solution effectively shortens the overall project cycle by 30% and saves comprehensive engineering construction and revision costs for customers. All products and construction processes fully comply with AISC, EN1090, CSA and local building energy-saving & safety codes, successfully passing local official strict inspection and certification. The professional multi-layer heavy anti-corrosion system provides 30-year long-term anti-corrosion quality guarantee for coastal harsh working conditions, greatly reducing later maintenance costs and improving the overall service life and safety stability of the building.
7. Customer Testimonial
