SECC Electrogalvanized Steel
SECC is cold-rolled steel with an electrolytically applied zinc coating. It combines the formability and dimensional control of cold-rolled sheet with basic corrosion protection. The uniform coating and good surface quality suit bending, stamping and riveted assembly. It is appropriate for mild exposure; welding and heat require review of the coating, and painting or powder coating can add protection.
Typical Applications
Server and computer chassis internals, power-supply housings, telecommunications sheet metal, electronics brackets and liners, and indoor equipment parts requiring corrosion protection and a consistent appearance. Avoid assuming suitability for severe corrosion or prolonged outdoor exposure.
Reference Properties & Manufacturing Parameters
Reference values are indicative and are not guaranteed specifications. Material grade, stock condition, processing, test method and part geometry can change the result. A listed temperature is not a continuous-use rating.
| Dimensional tolerance | ±0.2 mm |
|---|---|
| Minimum wall thickness | 0.8 mm |
| Reference temperature range | ≤200 °C |
| Reference tensile strength | 270–410 MPa |
| Reference density | 7.85 g/cm³ |
- Reference values vary with grade, material condition, part geometry and manufacturing process. Confirm final specifications during drawing review.
- Temperature figures are source reference values; the test method, loading and exposure duration are not specified and must be confirmed for the application.
Finishing Options
Confirm compatibility with the exact material grade and application. Define cosmetic surfaces, coating thickness, masking and any dimensional or performance requirements before manufacture.
Design & Manufacturing Review
- Specify sheet grade, thickness, finish and rolling direction where relevant. Confirm the selected stock before finalizing bend geometry.
- Review bend radii, bend reliefs, hole-to-bend distances and fastener access. Flat patterns must account for the actual forming process.
- Define weld locations, cosmetic surfaces and any coating or masking requirements.
