Steel strip is widely used in industries such as automotive, инструменты, строительство, and consumer products. While its mechanical properties—like strength, твердость, and elasticity—are critical, тот обработка поверхности also plays an important role. Different surface treatments not only enhance appearance but also improve долговечность, устойчивость к коррозии, и производительность.
So, what are the common surface finishing options for steel strip? Let’s take a closer look.
1. Natural Finish
This is the standard finish after cold rolling or heat treatment. It retains the basic metallic appearance of steel, often with a matte or slightly dark surface.
- Преимущества: Cost-effective, functional for general applications.
- Приложения: Internal components, construction parts, and non-decorative uses.
2. Яркий / Polished Finish
Steel strips can be mechanically polished or bright annealed to achieve a smooth, reflective surface.
- Преимущества: Enhanced aesthetic appeal, reduced surface roughness, and improved corrosion resistance.
- Приложения: Пружины, лезвия, shoe parts, бытовая техника, and visible precision parts.
3. Colored Finishes (Синий, Желтый, White)
Through controlled tempering or oxidation processes, steel strips can have protective color finishes.
- Blue Steel Strip: Achieved by tempering in a specific atmosphere, giving a dark-blue oxide layer.
- Желтый / White Finishes: Produced via heat treatment, providing additional identification and corrosion resistance.
- Приложения: Лезвия пилы, knives, шпатели, scraper blades, and tools requiring both aesthetics and protection.
4. Oiled Surface
Each coil is lightly coated with oil to protect against rust during storage and transport.
- Преимущества: Prevents oxidation and corrosion.
- Приложения: Export packaging, long-distance shipments.
5. Edge Finishing Options
Apart from surface treatment, тот edges of steel strip can also be finished:
- Slit Edge
- Square Edge
- Round Edge
These treatments improve safety, точность, and functionality in downstream applications.
Заключение
Surface finishing is more than just appearance—it directly affects the performance, долговечность, and usability of steel strip. Whether it’s bright polished for blades, colored for tools, или oiled for export protection, choosing the right surface finish ensures the steel strip meets your product’s specific requirements.
