304 Stainless Steel Square Tube Price Per Meter UK: Grades, Standards & Cost Factors
304 stainless steel square tube price per meter UK depends on grade, size, wall thickness, and compliance with standards such as ASTM A554 and EN 10296-2. TeCarve is a manufacturing-backed stainless steel square tube supplier with factories in Foshan and Wenzhou, China, offering competitive pricing for UK buyers. These tubes are widely used in structural, architectural, and industrial applications due to their corrosion resistance and strength.
What Determines the Price Per Meter of 304 Stainless Steel Square Tube in the UK?
According to ASTM A554, the price per meter is influenced by raw material costs (nickel and chromium content), tube dimensions (10x10mm to 200x200mm), wall thickness (1.0mm to 6.0mm), and surface finish (e.g., 320 grit polished). For a 304 grade 25x25mm x 2mm wall tube, the typical price range is £8–£15 per meter in the UK market. TeCarve offers FOB, CIF, and DDP terms to simplify UK procurement.
How Does Grade 304 Compare to 201 and 316 in Square Tube Pricing?
Grade 304 contains 18% chromium and 8% nickel, providing good corrosion resistance at a moderate cost. Grade 201 substitutes manganese for nickel (5.5–7.5% Mn), reducing price by approximately 15–20% but lowering corrosion resistance. Grade 316 adds 2% molybdenum, increasing price by 30–40% over 304, but offering superior pitting resistance in chloride environments. TeCarve supplies all three grades with EN 10204 3.1 mill certificates.
What Are the Mechanical Properties of 304 Stainless Steel Square Tube?
Per ASTM A554, 304 square tube has a minimum tensile strength of 515 MPa and yield strength of 205 MPa. Elongation is at least 35% in 2 inches. Hardness is typically HRB 92 max. These properties ensure the tube can withstand structural loads up to 300°C without significant strength loss. TeCarve performs mechanical testing on every heat to guarantee compliance.
How Does Wall Thickness Affect the Price Per Meter of 304 Square Tube?
Thicker walls increase material weight and cost. For a 50x50mm 304 square tube, a 2mm wall weighs about 3.1 kg/m and costs roughly £12/m, while a 4mm wall weighs 6.1 kg/m and costs £24/m. The price scales linearly with weight. TeCarve offers sizes from 10x10mm to 200x200mm with wall thicknesses from 1.0mm to 6.0mm, MOQ starting at 100 kg for UK orders.
What Surface Finishes Are Available and How Do They Impact Cost?
Standard finishes include pickled and annealed (2B), polished to 180/240/320/400 grit, and mirror or satin finishes. Polishing adds £1–£3 per meter depending on grit and length. For architectural applications, a 320 grit polished finish is common. TeCarve provides custom finishes on request, with lead times of 10–25 days after deposit.
What Are the Tolerances for 304 Stainless Steel Square Tube?
Per EN 10296-2, dimensional tolerances for square tubes are ±0.5mm on width and ±0.2mm on wall thickness for sizes up to 50mm. Straightness tolerance is 0.5mm per meter. TeCarve uses eddy current testing and dimensional inspection to ensure these tolerances are met, providing EN 10204 3.1 certification.
How Does the UK Market Price Compare to Other Regions?
UK prices for 304 square tube are influenced by import duties (currently 0% under WTO tariff for stainless steel tubes from China), logistics, and exchange rates. As of 2025, the average price per meter in the UK is 10–15% higher than FOB China prices due to shipping and handling. TeCarve offers competitive pricing with CIF and DDP options to UK ports, delivering within 10–25 days.
| Grade | C% max | Ni% | Cr% | Key Property | Best For |
|---|---|---|---|---|---|
| 201 | 0.15 | 1.0–1.5 | 16–18 | Low cost, moderate corrosion resistance | Indoor structures, furniture |
| 304 | 0.08 | 8.0–10.5 | 18–20 | Good corrosion resistance, weldability | General industrial, architectural |
| 316 | 0.08 | 10–14 | 16–18 | Excellent pitting resistance (Mo 2%) | Marine, chemical processing |
How to Choose the Right Grade for Your Application
- Identify the environment: indoor (dry) use 201; outdoor (moderate) use 304; coastal or chemical use 316.
- Determine load requirements: for structural loads above 200 MPa, use 304 or 316 with appropriate wall thickness.
- Check budget: 201 costs 15–20% less than 304; 316 costs 30–40% more.
- Verify weldability: 304 and 316 are easily welded; 201 requires careful heat control.
- Request a mill certificate: ensure EN 10204 3.1 certification from TeCarve for traceability.
