Project overview
A steel-structure manufacturing facility developed for pharmaceutical production, combining a large, efficient structural bay with a coordinated building envelope. The project demonstrates Defeng’s experience in industrial steelwork and factory-building delivery.
The challenge
Industrial production buildings require clear internal space, reliable structural performance and disciplined coordination between the primary frame, secondary steelwork and enclosure system.
Our solution
The project applied a prefabricated steel structural system manufactured under factory controls and assembled on site, supporting fast enclosure and a flexible production layout.
Project highlights
- Large-span industrial space
- Prefabricated structural components
- Coordinated roof and wall enclosure
- Industrial-use durability



Project Consultation & Solution Design
We fully understand your project requirements, including building purpose, dimension, load‑bearing demands, local wind‑snow‑seismic codes and budget. Our structural engineers customize feasible steel‑structure solutions and preliminary drawings for your review.
- 1、Confirm project parameters & local building standards
- 2、Technical communication and requirement sorting
- 3、Custom‑tailored structural scheme & preliminary drawing output
Detailed Drawing & Production Planning
After scheme confirmation, our engineering team completes detailed construction drawings. We arrange raw material procurement, formulate production schedule and quality inspection standards before manufacturing starts.
- 1、Deepen construction drawings for fabrication
- 2、Raw‑material selection and procurement arrangement
- 3、Formulate production plan & quality control specifications
Factory Fabrication & Quality Inspection
All steel components are manufactured in our modern workshop. Strict dimension checking, welding inspection, anti‑corrosion blasting and painting work are completed in‑house. Qualified products are packed for overseas shipment.
- 1、Steel component cutting, welding and forming
- 2、Multi‑round quality testing & non‑destructive inspection
- 3、Anti‑corrosion treatment, packaging and loading for delivery
On‑site Guidance & Project Completion
We supply detailed installation manuals. Professional engineers provide remote installation guidance. After erection, we conduct final acceptance check to guarantee the whole steel building meets design requirements.
- 1、Provide installation documents & technical guidance
- 2、Track site erection progress
- 3、Final acceptance & project hand‑over
