Procure raw materials from major Japanese steel manufacturers and prepare them for production in order to meet customers' demands
"Create the first form
＊We use a looper made in Japan to reduce line stoppage time and improve production efficiency "
Weld two edges of steel plate to create a tube shape
Shape the tube according to the required diameter
Cut tubes to the length required by customers
Clean two ends of tubes after cutting
Finished product packaging
"Procure raw materials from major Japanese steel manufacturers and prepare them for production in order to meet customers' demands
（T1.2mmm〜T4.5mm）
Coil is continuously put into 6 tanks for cleaning with HCl acid solution, acid solution after cleaning will be taken out of to the acid regeneration treatment system
After acid cleaning, coil is transferred to hot water cleaning line
After completing the above 2 steps, coil is put into the storage cage for next steps
Coil is cut according to requirements and rolled out to calculate the weight
"Coil is transferred to the continuous Pay off reel to prepare for the 6-high cold rolling process (2 presses, 2 intermediates and 2 rolls), this process produces coil rolls with thickness depending on customers' requirements
（T0.18mm～T2.0mm）
- Material is input into the Pay off reel for continuous production line
- After Pay off reel, coils are connected together for continuous
production
Treatment with NaOH alkaline solution for the coil to be clean before heat treatment
Coil is treated by direct and indirect heat to clean surface out of impurities, ensuring the adhesion between steel sheet and zinc aluminum layer, and to meet requirements on the elongation for different materials
- Galvanizing, 55% Al-Zn as requested
- Ensure the galvanizing level according to customer's requirements
Cool the plate temperature down
- Surface treatment with Skinpass, Tension Leveller, Resin (Anti-finger)
- Treating the coil surface with Anti-finger or Skinpass then transfer
to color-coating line
Wrap the coil according to the weight required by customers
- Input raw materials into manufacture line to prepare for the production
- Connect 2 material rolls for continuous production
The cage stores materials to connect the coil so that the production line works continuously
Clean material surface with iron brush to increase adhesion then clean with hot water
The purpose is to protect the coil surface from oxidation, and to increase the adhesion between the coil surface and paint coating layer
- Top coating
- The primer coating is between the material surface and the finished
paint layer on top
- Coating the paint on the backside
Through many production stages, the coil shape is affected that needs to be fixed
Cage for storing finished color-coating coil for the production line continuity
Wrap according to the weight required by customers
