sandblasting
It is used to obtain a more uniform surface texture and touch, which facilitates subsequent powder coating/painting consistency control (it is recommended to clearly define the texture target for the appearance surface).
Cold rolled electroplated plate_SECC
Cold rolled electroplated plate_SECC is documented with typical properties, suitable applications, finishing options, and design guidance for Sheet Metal Fabrication.
Quote checklist: Upload your 3D model and, when available, a 2D drawing. Identify the required process, material, quantity, critical dimensions, finish, appearance standard, and target delivery date.
Key Material and Manufacturing Parameters
Engineering note: Values below are typical reference ranges. Final manufacturability, tolerances, material condition, surface finish, cost, and lead time depend on the drawing, geometry, quantity, and selected process.
Upload CAD files and mark critical features for an engineering review before production.
| Process | Sheet metal fabrication (laser cutting/stamping/bending/riveting/welding, etc.) |
|---|---|
| Material | Cold rolled electroplated plate_SECC (electroplated galvanized steel plate) |
| Accuracy | ±0.2 mm |
| Minimum wall thickness | 1.0mm |
| Service temperature | 300-600℃ |
| Tensile strength | 450-1100MPa |
| Density | 7.7-8.5 g/cm³ |
| Appearance and surface | The surface has a galvanized layer and is basically corrosion-resistant; it is recommended to clarify the "appearance surface/non-appearance surface" and allowable trace standards for the appearance surface. If you need more stable appearance and color consistency, we recommend powder coating/painting and provide color numbers or reference pictures. |
| Structural suggestions | Please avoid placing the bending edges, hole positions and slots too close to the bending lines/edges; if assembly positioning is required, please provide 2D tolerance markings or note "key holes/critical surfaces". |
| Finishing | Sand blasting, blackening, oxidation, galvanizing, nickel plating, powder coating, painting |
| Typical lead time | Related to plate thickness, structural complexity, quantity and finishing; clear delivery and expedited options will be given after uploading the file |
Finishing
Blackening
Used to achieve a dark appearance with some protection; please indicate appearance and color expectations (darkness/consistency) in notes.
Oxidation
Used to improve surface protection and appearance; please describe functional requirements (protection/decoration) and appearance standards.
galvanized
Used to enhance corrosion resistance and surface protection; if you need to specify coating requirements (appearance/corrosion resistance/thickness target), please indicate in the remarks.
Nickel plated
Used to improve corrosion resistance and appearance consistency; suitable for structural parts and shell parts that have higher corrosion resistance or appearance requirements.
Dusting
Appearance scheme suitable for mass production of chassis cabinets, shells, etc.; please provide color number/reference image and gloss requirements (matte/semi-matte/high gloss).
spray paint
Suitable for color/texture control of cosmetic parts; it is recommended to note the definition of color, gloss and appearance surface, and indicate whether minor scratches/orange peel are allowed.
Why choose cold rolled electroplated plate_SECC
Basic corrosion resistance, more suitable for shell parts
The electro-galvanized layer provides basic protection and is suitable for the corrosion resistance needs of chassis cabinets, equipment shells and general structural parts.
Good formability, more friendly bending/flanging
Suitable for common sheet metal process routes (cutting/punching/bending/riveting/welding, etc.), convenient for rapid prototyping and small batches.
High adaptability to powder coating/painting
Suitable as a powder/paint base material to achieve a stable appearance; it is easier to control consistency after the appearance standard is clear.
Cost-friendly and versatile
It is more balanced between performance and cost and is suitable for most general structural parts and sheet metal shells.
Recommended Applications
- Chassis cabinet/equipment enclosure: Sheet metal parts that require basic corrosion resistance and stable appearance
- Brackets and general structural parts: Emphasis on cost and manufacturing efficiency
- Powder coating/paint cosmetic parts: Requires color and gloss consistency control
- Prototyping and small batches: Mature technology and controllable delivery pace
Consider Another Material or Process
- Strong corrosion/long-term outdoor exposure: It is recommended to evaluate stainless steel or higher level protection solutions
- Extreme strength/wear requirements: Recommended to evaluate higher strength steel or surface strengthening routes
- High appearance mirror/decorative surface: It is recommended to evaluate systems such as stainless steel brushing/polishing or aluminum alloy anodizing.
- Strong certification requirements for plating/coatings: Please note the standards/norms, we will evaluate according to the requirements
Design and DFM Guidelines
- Appearance surface definition: Please mark the appearance surface/non-appearance surface and allowable mark standards; it is recommended to choose powder coating/painting for cosmetic parts and provide reference pictures.
- The relationship between bending and opening: Try to avoid holes/slots that are close to bend lines and edges; if they must be close, please note the key dimensions and functional requirements for evaluation.
- Structural consistency: Minimize overly dense features and weak connections, and avoid deformation and assembly interference after bending; flanging/reinforcing ribs can be used if rigidity is required.
- Assembly holes and positioning: It is recommended to provide 2D tolerance marking (DWG/DXF/PDF) for key holes/positioning holes, or to clearly indicate "the size of key holes to be controlled" in the remarks.
- Surface treatment pre-communication: Powder coating/painting/nickel plating, etc. will affect the appearance and assembly coordination. It is recommended to determine the color number, gloss and masking requirements (such as grounding position/assembly surface) in advance.
