Stainless steel coils, as an important metal material, occupy an important position in various fields such as construction, industry, and home furnishings due to their unique properties and wide applicability. The following is a detailed summary of its core advantages:
1、 Excellent corrosion resistance
Strong chemical stability
The dense chromium oxide passivation film formed on the surface of stainless steel coils can effectively isolate the corrosion of oxygen, water vapor, and corrosive media (such as acid, alkali, salt), and is particularly prominent in humid, polluted, or coastal environments.
316 stainless steel coils have significantly improved resistance to chloride ion corrosion due to the addition of molybdenum element, making them suitable for strong corrosion scenarios such as seawater and chemical media.
Long term service life
Under normal maintenance conditions, the service life of stainless steel coils can reach several decades, far exceeding materials such as carbon steel and aluminum, reducing replacement frequency and full lifecycle costs.
For example, building curtain walls use stainless steel coils that do not need to be replaced within 50 years, while aluminum curtain walls need to be renovated every 10 years.
2、 Excellent physical performance
High strength and toughness
The tensile strength of stainless steel coils can reach 520-1030MPa (depending on the material), combined with good ductility (elongation at break ≥ 40%), and can withstand complex stresses without breaking.
Suitable for structures such as buildings and bridges in earthquake prone areas that require impact resistance and deformation resistance.
High temperature and low temperature resistance performance
High temperature stability: 310S stainless steel coil can be used for a long time at a high temperature of 1150 ℃, suitable for scenarios such as boilers, heat exchangers, and industrial furnaces.
Low temperature toughness: It can maintain toughness even in extremely cold environments of -50 ℃, suitable for polar scientific research stations, liquefied natural gas storage tanks, etc.
Lightweight advantage
Compared to carbon steel, stainless steel coils have a lower density (about 7.93g/cm ³), which can reduce structural weight and lower transportation and installation costs while meeting strength requirements.
3、 Aesthetic and Decorative
Diversified surface treatments
Bright surface: The surface is as smooth as a mirror, with high reflectivity, suitable for high-end building curtain walls, elevator cars, etc.
Foggy/matte: reduces light reflection, creates a soft visual effect, suitable for indoor decoration, home appliance panels, etc.
Etching/Drawing: Through chemical etching or mechanical drawing processes, texture and pattern customization can be achieved to enhance the design sense.
Color richness
Through PVD titanium plating, electrophoretic coating and other technologies, it is possible to achieve rainbow gradient effects such as black, gold, blue, rose gold, etc., meeting personalized decoration needs.
For example, the Dubai Sail Hotel uses colored stainless steel coils to decorate the exterior, combining durability and artistry.
4、 Processing and molding convenience
Flexible processing methods
Cold rolling/hot rolling: Cold rolled stainless steel coils have high thickness accuracy (± 0.05mm), suitable for precision parts; Hot rolled coils have high strength and are suitable for structural components.
Welding performance: Supports various processes such as argon arc welding and laser welding, with welding joint strength equivalent to the base material and good sealing performance.
Bending and rounding: Stainless steel coils can be bent into complex shapes such as cylindrical or curved shapes using a three roll or four roll plate rolling machine, suitable for rotating stairs, pipelines, etc.
Recyclability and environmental friendliness
Stainless steel coils are 100% recyclable, and the energy consumption during the recycling process is only one-third of that of primary smelting, without generating harmful waste.
Complies with green building certification standards such as LEED and BREEAM, and contributes to sustainable development.
5、 Economy and low lifecycle cost
Balance between initial cost and long-term benefits
Although the unit price is higher than carbon steel, the maintenance free period is as long as 25-30 years, and the overall cost is 40% -60% lower than galvanized steel.
For example, the Hong Kong International Financial Centre adopts stainless steel curtain walls that do not need to be replaced within 30 years, while aluminum curtain walls need to be renovated every 10 years.
Reduce maintenance costs
Surface self-healing ability: Even if there are local scratches, chromium element will react with oxygen to regenerate a passivation film, avoiding rust diffusion.
Pollution resistance: The surface is smooth and not easy to absorb dust. Cleaning only requires rinsing with water, reducing the use of chemical cleaning agents.
6、 Adaptability and multifunctionality
Cross industry applications
In the field of architecture: curtain walls, roofs, stair handrails, structural supports, etc.
Industrial fields: chemical equipment, food processing machinery, medical devices, automotive exhaust pipes, etc.
Home furnishing field: kitchen appliances, bathroom facilities, furniture decoration, etc.
customization
We can customize the thickness (0.1-30mm), width (100-2000mm), material (304/316/2205, etc.) and surface treatment process according to the needs, to meet the diverse scene requirements.
7、 Hygiene and Safety
Food grade standards
304 and 316 stainless steel coils comply with food contact safety standards such as FDA and EU, and are widely used in tableware, kitchenware, dairy processing equipment, etc.
Smooth and pore free surface, not prone to bacterial growth, easy to clean.
Fire performance
The melting point of stainless steel coil is as high as 1398-1454 ℃, and it does not release toxic gases at high temperatures, which meets the requirements of building fire protection regulations.
