Comprehensive Steel Supply: Hot Rolled, Cold Rolled & Galvanized

 

Beyond gas cylinder manufacturing, Shanghai Luzhen delivers a full spectrum of steel products across multiple processing methods and delivery formats:

 

1. Hot-Rolled (HR) Steel

  • Available Types:

Gas cylinder steel, structural steel, pipeline steel, anti-corrosion steel, wear-resistant steel, enameling steel, and automotive structural steel.

  • Characteristics:

High strength, superior formability, cost-effective for heavy-duty structural applications and construction machinery.

 

2. Cold-Rolled (CR) Steel & Strips

  • Available Types:

Deep-drawing CR steel, precision strip steel, high-tensile sheet steel.

  • Key Advantages:

Enhanced Mechanical Strength: Work-hardening increases yield and tensile strength by up to 20%.

Superior Surface Quality: Free from oxide scale; highly receptive to painting, powder coating, or plating.

Tight Dimensional Tolerances: Precise gauge control and minimal warping, essential for precision engineering and high-speed automated stamping lines.

  • Applications:

LPG cylinder components, automotive body panels, home appliances (refrigerators, ovens), precision enclosures, and metal furniture.

 

3. Galvanized Steel (GI) & Stainless Steel

  • GI Steel:

Exceptional atmospheric corrosion resistance for outdoor structural, automotive, and building materials.

  • Stainless & Carbon Steel Discs:

Precision-cut circular blanks engineered specifically for hardware, cookware, kitchenware, and gas cylinder end-dish forming.

 

Multiple Delivery Forms & Full Customization

 

 

To ensure seamless integration into your automated manufacturing lines, Shanghai Luzhen supplies steel in versatile processing conditions:

  • Steel Coils:

Slit and master coils for continuous stamping or roll-forming lines.

  • Steel Sheets & Plates:

Flat-cut sheets tailored for structural and enclosure fabrication.

  • Steel Strips:

Narrow precision strips with custom edge finishes.

  • Steel Discs (Blanking Discs):

Pre-cut circular blanks optimized for deep-drawing, drastically reducing scrap rates for cylinder and cookware manufacturers.

FAQ

 

Q1: What steel grade is best suited for LPG gas cylinder manufacturing?

A: HP295 is the industry-standard hot-rolled steel grade widely recognized for its excellent drawability and structural integrity under internal pressure. For lightweight designs requiring higher yield strength, advanced dual-phase steels like DP590 are increasingly specified.

Q2: Can Shanghai Luzhen supply pre-cut steel discs directly for cylinder end-caps?

A: Yes. We supply custom carbon steel, HP295, and DP590 circular steel discs cut to specified diameters (e.g., 580mm) and custom thicknesses, reducing processing steps and material waste for your factory.

Q3: What is the main structural advantage of cold-rolled steel over hot-rolled steel?

A: Cold rolling compresses the steel at room temperature, inducing strain hardening. This increases the material's yield strength, hardness, and dimensional precision while providing a clean, scale-free surface suitable for high-end surface treatment.
