The surface process of stainless steel handles has a significant impact on the touch, and different treatment methods will bring a completely different touch experience. The following is a detailed analysis of the common stainless steel handle surface processes and their tactile characteristics to help you choose the appropriate process according to your actual needs:
1. Mirror polishing (highlight)
- Tactile characteristics:
- Extremely smooth, with an obvious cold metal feeling when touched, and there is almost no resistance to finger sliding.
- It is easy to leave fingerprints and sweaty hands, which may cause a "sticky" or "slippery" feeling, especially in a humid environment.
- Applicable scenarios:
High-end hotels, modern and simple-style home furnishings (such as cabinets and glass door handles) need frequent cleaning and maintenance.
2. Brushing process (matte)
- Common types:
- Straight brushed: one-way texture, smooth touch with slight resistance, similar to silk texture.
- Random brushing: no irregular texture, rougher touch, better anti-slip.
- Tactile characteristics:
- The delicate frosted feeling weakens the coldness of stainless steel, and it is more comfortable to hold for a long time.
- The deeper the texture, the greater the friction (for example, #240 sand number is rougher than #400).
- Applicable scenarios:
Kitchen cabinets, frequently used drawer handles (such as 304 stainless steel brushed handles).
3. Sandblasting treatment
- Tactile characteristics:
- Uniform granular surface, touch like fine sandpaper, dry and slightly astringent, excellent anti-slip.
- It is "softer" than the brushing process, non-directional texture, suitable for large-area contact of the palm.
- Attention:
The thickness of sandblasting particles affects the touch (such as 80 mesh coarse sand vs 200 mesh fine sand).
- Applicable scenarios:
Outdoor door handles, industrial-style furniture (anti-slip and dirt-resistant).
4. Nano coating (PVD coating, anti-fingerprint coating)
- Tactile characteristics:
- The surface is close to ceramic texture, smooth but without mirror reflection, and the touch is warm and not cold.
- Strong anti-fingerprint performance, with a slight "dry" feeling when sliding.
- Advantages: The color can be customized (such as black titanium, champagne gold), while improving the cold touch of stainless steel.
5. Etching pattern
- Tactile characteristics**:
- The pattern area has a sense of unevenness (depth about 0.1-0.3mm), rich in touch levels, but the edges may be sharp.
- It is suitable for decorative handles, and it may not be as comfortable as the smooth craft when actually held.
- Improvement plan:
After etching, brushing is superimposed on brushing to balance beauty and feel.
6. Antique and old (cid cleaning, brush plating)
- Tactile characteristics:
- The surface deliberately retains uneven oxide layers or scratches, which are rough to the touch and slightly "burr".
- The retro style is unique, but you need to pay attention to whether the edges are rounded to avoid scratches.
Suggestions for selection
1. Priority anti-slip: choose sandblasting or deep brushing (disturbed pattern), especially suitable for wet and slippery environments (such as bathrooms).
2. Reduce the feeling of cold: nano-coating or matte brushing technology is the best.
3. Easy cleaning requirements: mirror polishing or PVD coating (but the mirror needs to be wiped frequently).
4. Durability: The scratch resistance of brushing and sandblasting is better than that of mirror.
Special tips:
- The same handle can be combined with technology (such as front drawing + side mirror), taking into account beauty and touch.
- When purchasing, it is recommended to touch the sample in kind, especially pay attention to whether the edge is chamfered to avoid cutting hands.
