2. Customer Pain Points & Project Difficulties
Before cooperation, the customer faced multiple core difficulties in this large-scale heavy steel project. Firstly, the project adopts ultra-large-span design with high top load-bearing requirements, putting forward strict demands on the strength and stability of the main steel structure. Secondly, the project is located in a coastal high-salt and high-humidity area, which easily causes steel corrosion, requiring super anti-corrosion performance for the whole building. Thirdly, local overseas construction codes are complex and rigorous, and the customer’s team lacked professional experience in international standard design and document approval. In addition, the customer had an extremely tight project schedule and needed rapid delivery and on-site completion to meet the factory production schedule. Finally, the original design drawings had many structural collision problems, and the customer was unable to complete professional drawing deepening and optimization, which would easily delay the whole project progress.
3. Customized One-Stop Solution
Based on the customer’s actual difficulties and international project standards, we provided a full-process customized heavy steel structure solution relying on our 30 years of overseas engineering manufacturing experience. First, we adopted professional BIM digital design to complete 3D overall modeling, structural collision detection, and drawing deepening optimization, solving the problem of unreasonable original design and realizing accurate engineering quantity calculation. Second, we selected Q460 high-strength heavy steel as the main structural material, which greatly improves the overall load-bearing, wind resistance and seismic performance, perfectly adapting to the large-span heavy-load usage scenario. Third, relying on our fully automatic heavy steel welding production line, all steel components are processed by CNC precision cutting and robot automatic welding, ensuring high precision and low defect rate of structural parts. Fourth, we provided full-set international standard construction drawings, factory inspection documents and certification files to help customers smoothly pass local official review and customs clearance. Meanwhile, we offeredprofessional overseas on-site installation guidance to standardize on-site construction and eliminate installation risks.
4. Production & Delivery Implementation Process
The whole project strictly follows international manufacturing and quality control standards. In the production stage, all heavy steel components adopt CNC intelligent cutting to ensure consistent dimensional accuracy; automatic robotic welding replaces traditional manual welding, realizing uniform welding lines and stable structural strength. After production, all components undergo professional shot blasting and high-standard anti-corrosion coating treatment, effectively improving the coastal corrosion resistance of the steel structure. Before shipment, our quality inspection team conducts full-dimensional inspection and non-destructive testing for all products. Finally, standardized container packaging and fixed loading are adopted to avoid deformation and damage during long-distance sea transportation. The whole production and delivery process is recorded with real photos and videos, realizing transparent and traceable project delivery.
5. Final Project Completion Effect
The heavy steel structure project has been successfully completed and officially put into use. The overall building presents a neat and stable industrial appearance, with smooth and atmospheric facade details and perfect overall structural coordination. The large-span internal space has no intermediate support columns, fully meeting the customer’s large equipment placement and heavy-duty crane operation needs. The overall structure has excellent wind resistance, seismic resistance and stability, adapting to local complex coastal climatic conditions. The anti-corrosion coating on the surface of steel components is intact and uniform, with good texture and strong durability. The aerial panoramic view shows the complete and standardized layout of the entire heavy steel factory building, fully reaching the international high-standard industrial construction level.
6. Core Cooperation Value
This one-stop heavy steel solution brings multiple core values to customers. First, the integrated design, production and delivery model effectively reduces customer comprehensive procurement and time cost, avoiding extra expenses caused by design modification and construction rework. Second, the overall project construction cycle is greatly shortened, helping customers put the factory into operation in advance and create economic benefits. Third, the whole project fully complies with local international safety and energy-saving building codes, successfully passing official acceptance and long-term safety assessment. Fourth, the whole building is equipped with professional heavy steel anti-corrosion technology and coating technology, providing 30-year long-term anti-corrosion quality guarantee for the steel structure. In addition, the high-strength steel structure design extends the overall service life of the building and reduces later maintenance costs.
7. Customer Testimonial
“We are very satisfied with the cooperation. Their professional BIM design team solved all our drawing and structural problems at one time. The factory’s automatic production equipment ensures excellent product precision and quality. The whole project was delivered on schedule, and the on-site installation guidance was very professional. The completed heavy steel factory fully meets our large-load production needs and local construction standards. It is a reliable professional heavy steel structure manufacturing and engineering partner worthy of long-term cooperation.” — Authorized by overseas engineering project customers
