Hairline SS Sheet
Hairline stainless steel sheet provides an ideal balance between cost, durability, and decorative performance. While its processing cost is higher than standard 2B finish, it remains significantly more economical than mirror finishes.
- Description
Hairline stainless steel sheet (HL finish) refers to a brushed surface finish created by continuous linear grinding on stainless steel. The result is a fine, uniform texture with long, straight lines, giving a modern and elegant appearance.
Compared with mirror or matte finishes, hairline finish offers a balance between aesthetic appeal and practicality, especially in architectural and decorative applications.
Is the Production Cost of Hairline SS Sheet High?
The cost of hairline stainless steel sheet is generally moderate to slightly higher than standard finishes like 2B, but lower than mirror (8K) finishes.
Cost Breakdown Factors
- Base Material Cost
- Depends on grade (304, 316, etc.)
- Accounts for the largest portion of total cost
- Surface Processing Cost
- Hairline finish requires mechanical brushing using abrasive belts
- Additional labor and equipment increase cost compared to 2B finish
- Consistency Requirements
- Uniform grain direction and texture control require skilled processing
- Large sheets need precise handling to avoid visible defects
- Thickness and Size
- Thicker sheets increase grinding difficulty and cost
- Custom sizes may add processing cost
Cost Comparison (Relative)
| Finish Type | Cost Level | Description |
|---|---|---|
| 2B Finish | Low | Standard industrial finish |
| Hairline (HL) | Medium | Brushed decorative finish |
| No.4 Finish | Medium | Slightly coarser than HL |
| Mirror (8K) | High | Highly polished, reflective |
Conclusion:
Hairline finish is cost-effective for decorative use, offering premium appearance without the high cost of mirror polishing.

Common Grades for Hairline SS Sheet
Hairline finish can be applied to various stainless steel grades, depending on environment and performance requirements.
Typical Grade Selection
| Grade | Type | Features | Typical Use |
|---|---|---|---|
| 304 | Austenitic | General corrosion resistance | Indoor decoration, elevators |
| 304L | Austenitic | Lower carbon, better weldability | Fabricated structures |
| 316 | Austenitic | مقا corrosion resistance (Mo added) | Coastal and chemical environments |
| 316L | Austenitic | Improved corrosion + weldability | Marine, high-end projects |
| 430 | Ferritic | Lower cost, magnetic | Indoor decorative panels |
Grade Selection Guidelines
- 304: Most widely used, cost-effective for indoor use
- 316/316L: Recommended for outdoor or corrosive environments
- 430: Suitable for budget indoor applications with lower corrosion requirements
Hairline vs Other Stainless Steel Finishes
| Property | Hairline (HL) | 2B | Mirror (8K) |
