Product Introduction

DC01 Galvanized Steel Pipe: High-Performance Corrosion Resistance for Demanding Industries.‌

‌Engineered for Precision: Automotive, Energy & Heavy Machinery‌

DC01 galvanized steel pipe is a ‌cold-rolled, low-carbon steel‌ (C ≤ 0.12%) with a yield strength of 140–280 MPa, featuring advanced zinc coatings (5–40 µm) for extreme corrosion resistance. Ideal for high-stress environments like oil rigs and automotive chassis, its ‌micro-alloyed composition‌ ensures 8–12x longer lifespan than untreated steel in saltwater or chemical exposure.


‌Certifications & Key Advantages‌

  • ‌EN 10142 & ASTM A653 Certified‌: Compliant with JIS G3302 and GB/T 2518 standards.
  • ‌Cost Efficiency‌: 35% lower lifecycle costs vs. stainless steel 304.
  • ‌Custom Sizing‌: Thickness 0.1–300 mm (±0.15 mm), width up to 3 meters.
  • ‌MOQ 5 Tons‌: Hot-dip galvanized (HDG) or electroplated (EG) finishes available.

‌Technical Specifications‌

  • ‌Electroplating (EG)‌: 5–25 µm coating for indoor/low-humidity use.
  • ‌Surface Prep‌: ISO 8501-1 Sa2.5 blast cleaning (25–75 µm profile).

‌Dimensional Tolerances‌

Parameter Tolerance
Thickness ±0.15 mm
Outer Diameter ±0.5% of nominal size
Length ±10 mm

‌Applications‌

  1. ‌Automotive‌: Exhaust systems, fuel tanks, and structural frames.
  2. ‌Energy‌: Oil well casings, nuclear reactor cooling pipes.
  3. ‌Construction‌: Elevator guide rails, bridge cables, and HVAC ducts.
  4. ‌Heavy Machinery‌: Mining equipment, hydraulic cylinders.

‌Fabrication Guidelines‌
