Factory Tour
Step inside our 50,000m² manufacturing facility where precision engineering meets industrial-scale production.

Where Quality
Takes Shape

Every Steely Metal product begins its journey in our state-of-the-art manufacturing facility in Nanjing, China. From raw steel coil to finished racking system, we control every step of the process.

Our 50,000m² factory houses 12 dedicated production lines operating 24/7 during peak seasons. With over 300 skilled workers and engineers, we have the capacity to produce and ship 200+ containers per month to clients worldwide.

From Steel to Shelf

Our manufacturing process combines automated precision with skilled craftsmanship. Every step is monitored for quality and consistency.

1

Raw Material Inspection

Certified-grade steel coils arrive from approved mills with mill test certificates (MTC). Every batch is verified for chemical composition, yield strength, and dimensional accuracy before entering production.

2

CNC Cutting & Punching

Computer-controlled cutting and punching stations shape beams, uprights, and braces with sub-millimeter precision. Automated feeders handle high-volume runs with consistent accuracy.

3

Roll Forming

Cold roll forming lines progressively shape flat steel into complex profiles — uprights, box beams, step beams — maintaining uniform cross-sections across thousands of meters.

4

Welding & Assembly

Robotic and semi-automatic welding stations join components with consistent penetration and strength. Frame assembly jigs ensure perfect alignment every time.

5

Powder Coating

Components pass through a multi-stage pretreatment (degreasing, phosphating, rinsing) before electrostatic powder coating and high-temperature curing. Solvent-free process, available in standard RAL colors.

6

Quality Inspection & Packing

Every batch undergoes dimensional checks, coating thickness testing, and load verification. Products are carefully packed with protective wrapping, labeled, and palletized for container loading.

Advanced Manufacturing

We invest continuously in the latest manufacturing technology to ensure precision, efficiency, and consistent quality at scale.

CNC Turret Punch

High-speed servo-driven punching with automatic tool changers. Processes up to 6mm steel with ±0.1mm accuracy.

Roll Forming Lines

8 dedicated cold roll forming lines for uprights, beams, and bracing. 24-stand progressive forming with in-line punching.

Robotic Welding Cells

Multi-axis robotic arms with laser seam tracking. Consistent weld quality across high-volume production runs.

Powder Coating Line

Fully automated conveyorized coating line: pre-treatment → drying → electrostatic spray → curing oven. 60m tunnel length.

Hydraulic Presses

100-500 ton capacity presses for beam end-plate forming and connector stamping with interchangeable die sets.

Testing Lab

In-house load testing rig for beam deflection and frame stability verification. Coating thickness gauge and salt spray chamber.

Inspected at
Every Stage

Quality is not a final checkpoint — it is embedded in every step of our manufacturing process. From incoming raw material to outgoing finished goods, multiple inspection gates ensure nothing leaves our factory that doesn't meet our standards.

Our ISO 9001:2015 certified quality management system defines clear procedures, acceptance criteria, and corrective action protocols. Every inspector is trained and certified for their specific station.

Incoming QC

Steel coil inspection: thickness, width, surface quality, MTC verification

In-Process QC

Dimensional checks at cutting, punching, forming, and welding stations

Final QC

Coating thickness, color matching, assembly fit test, load verification

Pre-Shipment Inspection

Packaging integrity, labeling accuracy, quantity verification, container loading supervision
