Our Services
We always guarantee the best quality of goods and services to customers
Slitting
Our slitting lines are designed for reliability and precision, capable of handling diverse steel types and especially adept with Electrical Steel (Silicon Steel). With cutting-edge PE film coating technology and rigorous tolerance control, we guarantee products that satisfy the most demanding requirements.
MACHINE XB1350
Finished strip data:
- Coil id: 508 / 610 mm. Insert to supply 02 rubber sleeve where is appropriate
- Coil weight: 15t (Max)
- Slit tolerance: ± 0.50 mm
-
Camber rate:
- 1.0mm (length 1000m)
- ≤2.0mm (length 2500m)
- Min slits width: 22mm
Cutting
Global A&B's cutting lines excel in processing a wide variety of steel materials, including specialized Electrical Steel (Silicon Steel), ensuring high-quality, precision-cut products. Our cutting technology incorporates advanced PE film coating and strict tolerance control, meeting the most stringent customer standards.
MACHINE CT1350
Finish data:
- Sheet cutting length: 200-3000 mm. Step adjustment for length must be fine (0.50mm for one adjust). It means we can cut the sheet with length 1001.5mm or 1001.1mm or only can cut 1000mm
-
Cut tolerance:
- L=1m ≥ 0.50mm
- Diagonal tolerance: L≥1.20mm
- Length tolerance: L≥0.50mm
- Burr: <3% thickness
- Flatness: ≤4 mm for length 1000 mm
Packing
Global A&B's packing lines are the final step in our commitment to quality and customer satisfaction. We understand that the protection and integrity of the product during shipping and handling are just as important as the manufacturing process itself. Our packing lines are equipped with innovative solutions tailored to the specific needs of the wide range of materials we handle, including the delicate and high-value Electrical Steel (Silicon Steel) products.
