20 Gauge Galvanized Steel

The 20 gauge (0.0396 inches, 1.0058 mm) in 20 gauge galvanized steel refers to the American thickness standard. This thickness offers high strength, lightweight properties, and excellent corrosion resistance.

Wanzhi Steel, a specialized supplier of 20-gauge galvanized steel, strictly adheres to international standards such as ASTM, JIS, and GB in production. We offer customized zinc coating weights and surface treatments, with products exported to over 120 countries, positioning us as a global supplier of galvanized steel products.

20 Gauge Galvanized Steel Advantages

• Sufficiently robust: Capable of withstanding structural loads and impacts, suitable for chassis enclosures, building envelopes, and medium-sized equipment.
• Sufficiently lightweight: Facilitates manual handling, bending, and installation, effectively reducing logistics and construction costs.
• Excellent workability: This thickness is ideal for cutting, stamping, bending, and forming operations.
• Wide Application Range: With zinc coating options from Z30 to Z275 g/m², products can be matched to specific environments from dry interiors to coastal/industrial zones.
• Strong Coating Compatibility: An excellent substrate for further processing like pre-painted coating (PPGI coil) and film lamination (laminated decorative panels).

Recommended selection

• Dry indoor environments / Low-cost requirements: Prioritize Z60 (G30), Z80 (G40);
• General Outdoor / Universal Applications: Opt for Z120 (G60) for best cost-performance ratio;
• Coastal / High-Humidity / Overseas Projects: Select Z180 (G90) or Z275 (G90);
• High Corrosion / Ultra-Long-Life Requirements: Directly choose Z350 (G115).

20 Gauge Galvanized Steel Product Type

• Galvanized flat sheet/coil: The most basic sheet/roll is a flat product cut to a specific size. The galvanized coil is easy to transport and store, and can be processed continuously as needed.
• Corrugated galvanized steel sheet: The galvanized steel sheet is processed into a sheet with a specific waveform, such as a trapezoidal, wavy, etc. through roller cold bending and other processes, and has good mechanical properties.
• Punching/checkered galvanized steel sheet/coil: Punching holes of various shapes and sizes on galvanized steel sheets, or rolling out specific textures, can be used for ventilation, sound insulation, anti-slip, decoration and other occasions.
• Patterned printed/color-coated galvanized sheet: The surface has patterns, which increases friction and aesthetics. It is often used for stair steps, platform pedals, etc., and also has a certain decorative effect.

20-gauge galvanized steel packaging

Packaging of 20 gauge galvanized sheet

Iron sheet packaging: For galvanized sheets cut into fixed lengths, iron sheet packaging is generally used. The inner lining is moisture-proof paper to prevent the steel sheet from getting damp and rusting, and the outer lining is tied to the bracket with iron waist. The tying must be firm to prevent the galvanized sheets inside from rubbing against each other and affecting the surface quality.

Packaging of 20 gauge galvanized coil

Roll packaging: Galvanized coils are usually first covered with moisture-proof paper, then the guard ring is fixed in the shaft, the annular anti-collision angle is fixed to the outer ring, and then fixed with strapping tape, and finally the outer layer is wrapped with rust-proof woven cloth or plastic cloth to play a role in moisture-proof, collision-proof and oxidation-proof.
