Finishing
Blackening
It is suitable for scenes that require dark appearance and certain protection requirements; if spray coating/electroplating is required later, please indicate the process priority in advance.
Oxidation
Used for surface protection and appearance treatment; if there are conductive grounding requirements or partial shielding requirements, please mark them in the drawings/notes.
galvanized
Used to improve corrosion resistance and durability; if the parts contain welding or high-appearance surfaces, it is recommended to perform DFM evaluation processing sequence first.
Nickel plated
Used to further enhance surface protection and appearance consistency; the impact of coating thickness must be considered for mating surfaces/threads/hole locations.
Dusting
Suitable for cases where both appearance and durability are taken into consideration, such as shells/boxes; please note the acceptance criteria for color, gloss, texture and key surfaces.
spray paint
Suitable for color consistency and appearance grade control; can be implemented according to matte/gloss and color number requirements. It is recommended to provide reference pictures for more accuracy.
Why choose hot-dip galvanized steel plate_SGCC (sheet metal fabrication)
Corrosion resistant and more friendly
Suitable for structural and shell parts that are more sensitive to corrosion; it is easier to obtain stable protection performance under general working conditions.
Cost and performance balance
When used for general sheet metal parts, cost and manufacturability are taken into consideration, and it is suitable for rapid iteration from prototypes to small batches.
Wide range of processing adaptability
It can be combined with cutting, bending, punching, riveting and other sheet metal processes to achieve structural forming, and is suitable for box/bracket structures.
Rich finishing options
Supports sandblasting, blackening, oxidation, galvanizing, nickel plating, powder coating, and painting, which can be achieved according to the combination of appearance and protection goals.
Recommended Applications
- General sheet metal structural parts: Shell/cover/bracket/mounting plate, etc.
- cost sensitive: Want to balance general strength with cost
- Corrosion resistance requirements: Pay more attention to rust prevention and stability in the use environment
- Requires powder/paint appearance: Control key aspects and acceptance criteria according to appearance grade
It is not recommended to use it directly (it is recommended to change materials/change routes)
- Strength/wear resistance limit requirements: Recommended to evaluate higher strength steel or alloy systems
- Long-term high temperature and thermal cycling: It is recommended to select a more matching material and surface system based on the temperature resistance target.
- Strong assembly and precision fit: It is recommended to mark tolerances on key holes/critical surfaces and evaluate secondary finishing options
- Extremely high appearance mirror requirements: It is recommended to use a more suitable combination of materials and surface processes.
Design and DFM suggestions (Hot-dip galvanized steel plate_SGCC | Sheet metal fabrication)
- Bending and unfolding: Please provide an unfolded diagram or state "expand by us" in the remarks; the key bending dimensions/appearance surfaces need to be defined in advance to facilitate the selection of bending direction and compensation strategy.
- Hole to Bend/Hole to Margin: Holes that are too close may easily deform or crack. It is recommended to reserve sufficient margins for holes/slots; if space is limited, please mark the key requirements and conduct a DFM assessment first.
- Fastening and assembly: If threaded connections are required, it is recommended to give priority to solutions such as rivet nuts/rivet studs. For conductive ground planes and mating surfaces, it is necessary to indicate whether coating coverage is allowed.
- Welding and plating effects: If a welded structure is included, please mark the weld position and appearance requirements on the drawing; the order of welding and subsequent spray coating/electroplating will affect the consistency of protection and appearance, so it is recommended to clarify the priority.
- Appearance and painting acceptance: Please clarify the color, gloss, texture and key surface (A side) standards for powder coating/painting; it is recommended to specify the appearance requirements of corners, bends and hole edges separately.
