This Custom Electro-Galvanized Steel Bracket is manufactured utilizing Trumpf TruPunch 5000 and TruBend 5230 centers to ensure dimensional consistency. The fabrication workflow integrates CNC punching for countersunk holes and adjustment slots with automated bending to maintain tolerances of ±0.1mm. Produced under IATF 16949 quality controls, the part features a yellow chromate finish for durable corrosion protection in industrial environments.

Key Features & Advantages
✨ Corrosion Protection: The carbon steel substrate is finished with electro-galvanized yellow zinc plating (chromate passivation), creating a barrier against oxidation and rust in industrial environments.
✨ Precision Fabrication: Manufactured using Trumpf TruPunch 5000 and TruBend 5230 equipment, achieving dimensional tolerances of ±0.1mm for bending angles and hole positions.
✨ Functional Design: Features CNC-punched adjustment slots for flexible mounting and chamfered countersunk holes to ensure flush fastener installation.
✨ Quality Control: Production is monitored under IATF 16949 and ISO 9001 quality management systems, ensuring lot-to-lot consistency.
✨ Material Versatility: Available in Cold Rolled Steel (SPCC) or Electro-Galvanized Steel (SECC) based on specific structural requirements.
