1. The core differences between 201, 304, 316 stainless steel
(The comparison table remains unchanged, emphasizing material characteristics)
2. Select according to specifications and usage scenarios
1. Common specifications and applicable scenarios
| Diameter | Thickness | Applicable scenarios | Recommended Material |
|---|---|---|---|
| 16mm | 0.5mm | Light-duty decorative handrails, furniture accessories | 201/304 |
| 38mm | 0.5mm | Home stair handrails, shopping mall guardrails | 304 |
| 51mm | 0.5mm | Outdoor heavy handrails, engineering guardrails | 304/316 |
Note:
-
0.5mm thickness is suitable for decoration and low load-bearing scenarios. If higher strength is required (such as crowded areas), it is recommended to choose 1.0mm wall thickness.
-
Coastal or high humidity areas, 316 is preferred regardless of diameter and size.
2. Specification adaptability of different materials
-
201 tube: Suitable for indoor dry environments with a diameter of 16mm/38mm (such as home stairs).
-
304 tube: universal choice with 38mm/51mm diameter (available indoor and outdoor).
-
316 tube: a 51mm diameter high corrosion environment (chemical, seaside).
3. Supplementary of key purchasing factors
1. Advantages and disadvantages of 0.5mm thickness
-
Advantages: Light weight, low cost, easy to process and bending.
-
Disadvantages: It has weak impact resistance and may deform for long-term use (column support needs to be strengthened).
2. Installation suggestions
-
16mm thin tube: Paired with glass clips or hidden fixtures to maintain beauty.
-
38mm/51mm pipe: When welding or fixing screws, you need to pay attention to the anti-rust treatment of the pipe mouth (especially 0.5mm thin walls are easy to weld).
IV. Price reference (updated to 0.5mm thin-walled quotation)
| Material | 16mm | 38mm | 51mm |
|---|---|---|---|
| 201 | 12-18 yuan/meter | 18-25 yuan/meter | 25-35 yuan/meter |
| 304 | 20-30 yuan/meter | 30-45 yuan/meter | 45-60 yuan/meter |
| 316 | 35-50 yuan/meter | 50-75 yuan/meter | 70-90 yuan/meter |
5. Summary: Key points for purchasing thin-walled handrail pipes
-
Indoor drying 201 (for 16mm decoration), Outdoor junction 304 (over 38mm).
-
0.5mm thin walls need to be cautious: It is suitable for low load-bearing scenarios, and it is recommended to thicken it with high strength requirements.
-
Coastal/chemical area directly goes to 316 to avoid late replacement costs.
