Technology & Digitalisation
·
BIMdriven workflow: Every project is fully modelled in BIM, enabling seamless data integration from design to fabrication and site installation.
·
·
Proprietary nesting software (Software Copyright No. 15064872) automatically optimises steel plate utilisation, directly interfaces with laser cutting, and ensures 100% dimensional accuracy.
·
·
“OneModeltoEnd” smart manufacturing system covers nesting, laser cutting, robotic welding (including multiaxis, submergedarc, and boxcolumn welding), shot blasting, and automatic spraying – all with full traceability.
·
·
Realtime production control: Our digital platform allows clients to monitor fabrication progress, logistics, BIM models, and financial status via mobile devices – breaking information silos and ensuring transparency.
·
2. Our Procurement Philosophy – Partnering with the Best
Strategic Material Sourcing
Honglu procures all raw materials directly from primary steel mills – no intermediary traders. We have longterm annual frame agreements with:
·
Baowu Steel – 2.6 million tonnes/year
·
·
Shagang Steel – 1.0 million tonnes/year
·
·
Anyang Steel – 1.0 million tonnes/year
·
·
HBIS Group – 0.5 million tonnes/year
·
All steel plates are fully killed (finegrained), and plates thicker than 20mm in Q355B grade meet Level III ultrasonic inspection standards. Every plate is traceable to the specific mill heat number, project, and even the final structural member.
Coating & Consumables
We maintain strategic partnerships with worldleading paint suppliers Jotun (10,000 t/year) and PPG (10,000 t/year), who provide onsite technical service at our factories. Our inhouse welding wire plant produces 200,000 tonnes annually using premium wire rods from Qingdao Steel and HBIS, ensuring stable weld quality.
Quality Assurance – Full Traceability
Each of our production bases has a central laboratory that tests every batch of steel (mechanical properties, chemical composition, ultrasonic inspection), welding consumables, and paint (zinc content, resin content, volume solids). All test results are stored online.
Our proprietary workreporting and QRcode traceability system (Software Copyright V1.0) ensures that every single component can be traced to:
·
The responsible nesting planner,
·
·
The operator and inspector of each fabrication step,
·
·
The specific steel plate and its mill certificate (stamped with official red seal, not photocopies).
·
This system eliminates the use of nonconforming materials and guarantees full accountability – a critical safeguard for structural safety.
