What Is TP304 sandblasted stainless steel pipe?
TP304 sandblasted stainless steel pipe is based on 304 stainless steel, conforming to ASTM A213/A269/A312 standards. The surface is treated with sandblasting (usually Sa2.5 grade treatment), showing a matte, non-reflective surface. On the basis of retaining the original corrosion resistance and processing performance of 304 stainless steel pipe, its anti-slip, wear resistance and coating adaptability are improved, which is suitable for industrial and construction fields with higher requirements for surface performance.

In addition, GNEE offers a wide range of stainless steel tube surface treatments, including:Mirror Polishing (8K),Hairline Finish,Brushed Finish (No.4),Pickling and Passivation.
Advantages
Anti-Slip & Wear Resistance:
After sandblasting, the surface roughness of TP304 stainless steel round tubes reaches Ra 12.5–25 μm (compared to ≤ Ra 1.6 μm for standard polished tubes), increasing the friction coefficient by 40%. This significantly enhances anti-slip performance, making it ideal for stair railings in wet environments, non-slip strips on ship decks, and industrial equipment platforms.
Corrosion Resistance:
Retaining the inherent corrosion resistance of 304 stainless steel, the tube offers 5 times the atmospheric corrosion resistance of carbon steel. In non-coastal environments, it provides over 20 years of weather resistance, and passes the salt spray test (NSS) for 1000 hours without substrate rusting.
Scratch Resistance:
The surface hardness of ASTM A269 TP304 pipe increases from HV 150 to HV 220 after sandblasting, improving resistance to daily knocks and scratches and extending the visual appearance life by 2–3 years.
