Stainless Steel Sheets: Types, Uses, and How to Source from China
Stainless steel sheets are essential raw materials in industries ranging from construction to food processing. Their corrosion resistance, durability, and aesthetic appeal make them a preferred choice for manufacturers worldwide. With China being a leading supplier, understanding how to source quality stainless steel sheets is crucial for buyers.
How to Find Reliable Stainless Steel Sheets from China in 2025
China remains a top producer of stainless steel sheets, offering competitive pricing and diverse options. To find reliable suppliers:
- Check certifications like ISO 9001 and SGS reports
- Review supplier history on platforms like Alibaba
- Request material test reports (MTRs) for quality verification
- Consider manufacturers with in-house R&D departments
Top industrial zones for stainless steel production include Wuxi, Foshan, and Shanghai. Many factories now offer customized cutting and finishing services.
What Buyers Should Know Before Buying Stainless Steel Sheets from China
Key considerations include:
- MOQ requirements (typically 1-5 tons)
- Lead times (2-4 weeks for standard orders)
- Shipping costs and logistics
- Payment terms (30% deposit is common)
Always request samples before large orders. Reputable suppliers provide sample pieces (usually 300x300mm) for testing.
Types of Stainless Steel Sheets
By Grade
- 304: Most common, excellent corrosion resistance
- 316: Superior for marine environments
- 430: Cost-effective for non-critical applications
- 201: Budget alternative with moderate durability
By Finish
- No. 1 (Hot rolled, annealed)
- No. 4 (Brushed finish)
- BA (Bright annealed mirror-like)
- HL (Hairline finish)
Functions and Features of Stainless Steel Sheets
Key advantages include:
- Corrosion resistance (10-20 years in harsh environments)
- High strength-to-weight ratio
- Hygienic surface (critical for food/pharma)
- Temperature resistance (-200°C to 800°C)
- 100% recyclable
Scenarios of Stainless Steel Sheets
Common applications:
- Construction: Cladding, roofing (0.4-3mm thickness)
- Industrial: Chemical tanks, machinery (3-6mm)
- Food Service: Countertops, equipment (1.5-2mm)
- Transportation: Automotive trim, rail cars
How to Choose Stainless Steel Sheets
Selection factors:
- Environment (indoor/outdoor, chemical exposure)
- Required lifespan
- Aesthetic requirements
- Budget constraints
For architectural use, No. 4 finish 304 sheets are popular. Food processing often requires 316 with BA finish.
Stainless Steel Sheets Q & A
Q: What thickness is best for kitchen countertops?
A: 1.2-2mm provides durability without excessive weight.
Q: How to distinguish 304 from 201 grade?
A: Use a manganese detection spray - 201 contains 5-7% manganese.
Q: What's the price difference between Chinese and European sheets?
A: Chinese sheets typically cost 20-30% less for comparable quality.
Q: Can stainless sheets be welded?
A: Yes, but requires proper technique - TIG welding is preferred.
Q: How to prevent scratching during installation?
A: Use protective film and non-metallic tools.
