Product Definition and Classification
Hot-dip galvanized steel coils are corrosion-resistant steels made by dipping carbon steel coils into molten zinc (approximately 450°C) to form a zinc-iron alloy layer (Zn-Fe). Based on the weight of the zinc layer, they are categorized as follows:
Z60-Z120: Zinc layer 60-120g/m² (light corrosion protection)
Z180-Z275: Zinc layer 180-275g/m² (heavy corrosion protection, such as building structures)

Technical Parameters and Pricing
Thickness 0.12-6.0mm (common 0.3-3.0mm)
Zinc layer weight 30-600g/m² (double-sided)

Core Application Scenarios
Construction: Roof panels, wall panels (requires a zinc coating of Z180 or higher)
Home Appliance Manufacturing: Refrigerator back panels, washing machine housings (Z60-Z80)
Automotive: Chassis components, exhaust pipes (requires fingerprint-resistant treatment)

Hot-rolled 304 stainless steel coils (ASTM A240/A240M standard) are produced through a high-temperature rolling process, offering excellent corrosion resistance and processability. They are suitable for applications in construction, chemical engineering, food processing, and other fields.

Surface finishes: 2B (matte), BA (mirror), and No. 1 (industrial finish).
Thickness range: 1.0-50mm (common 1.0-10mm)
Thickness: 1.0-50mm (customizable)
Width: 800-1500mm (coil)
Standard: ASTM A240/AISI 304
Delivery condition: Hot-rolled (HR) or annealed

Applications
Architectural decoration: Curtain walls, elevator panels (requires 2B/BA finish)
Industrial equipment: Chemical containers and pipelines (requires acid corrosion resistance)
Food processing: Processing equipment (requires FDA compliance)

Hot-rolled stainless steel coils are made from stainless steel through a high-temperature rolling process. They are primarily categorized into the following types:
Material Classification
Main types include austenitic stainless steel (such as 304 and 316), ferritic stainless steel, martensitic stainless steel, and duplex stainless steel. 304 and 316 are currently the most popular grades, offering excellent corrosion resistance.
Thickness Range
Hot-rolled coils typically range in thickness from 3mm to 150mm and are primarily used in structural components, pressure vessels, and other applications.
