Representation of base materials in different standard systems

(1) European Standard (EN 10346)

• DX51D+AZ150: Low carbon steel for ordinary cold forming, yield strength 120-280MPa.
• DX52D+AZ150: Stamping grade low carbon steel, higher formability.
• DX53D+AZ150: Deep drawing grade low carbon steel, optimal formability.

(2) Chinese Standard (GB/T 2518)

• DC51D+AZ150: Low carbon steel for ordinary cold forming, yield strength 120-280MPa.
• DC52D+AZ150: Stamping grade low carbon steel, higher formability.
• DC53D+AZ150: Deep drawing grade low carbon steel, optimal formability.
• Q345G+AZ150: Low alloy high strength steel, yield strength 345MPa.

(3) American Standard (ASTM A792)

• CS Type B AZ150: CS stands for Commercial Steel.
• DS Type B AZ150: DS stands for Drawing Steel.

Recommended substrate selection for different scenarios

Building and Envelope Systems

• Roof/wall: DX51D+AZ150/ DC51D+AZ150. Because low-carbon steel has good formability and optimal cost.
• Large industrial plants: S350GD+AZ150/ SS Grade 40 AZ150, which can resist wind pressure and can be used in large-span roofs or typhoon-prone areas.

Structural Engineering

• Steel structure sandwich panel: S550GD+AZ150/ HSLAS Grade 50 AZ150, as a load-bearing panel, has ultra-high strength and can withstand the overall load after compounding.
• Warehouse partition wall/floor decking: S250GD+AZ150 / SS Grade 33 AZ150. Medium strength balances load-bearing and cost, suitable for vertical installation or short-span floor slabs.

Industrial Equipment and Transportation

• Truck body/container shell: DX53D+AZ150/ DS Type B AZ150, deep drawing grade to adapt to complex bending and forming.
• Harvester/silo: S350GD+AZ150 + fingerprint-resistant coating. High strength to resist mechanical impact, fingerprint-resistant coating is anti-fouling and easy to clean, suitable for humid and fertilizer-corrosive environments.

Special Environment

• Coastal/high humidity areas: S250GD+AZ150 + PVDF coating, aluminum zinc and fluorocarbon coating provide double anti-corrosion protection.
• Chemical plant/acidic and alkaline environment: S550GD+AZ150 + epoxy resin coating, ultra-high strength substrate resists chemical medium stress corrosion, epoxy coating specifically prevents acid and alkali.

Cost-sensitive projects

• Temporary buildings/fences: DX51D+AZ150, the most economical solution, meeting the needs of short-term use (5-8 years).
• Simple storage shed: S250GD+AZ150, which is stronger than DX51D, can reduce the number of steel frame supports, and has a lower overall cost.

Galvalume AZ150 vs. Z275 Galvanized steel

• Corrosion resistance: Galvalume AZ150 is superior to Z275 galvanizing, especially resistant to industrial atmospheres.
• Heat resistance: Z275 can only withstand about 200°C, while Galvalume AZ150 can withstand 315°C continuously and 600°C for a short period of time.

• Conductivity: Aluminum-zinc alloys conduct electricity more evenly and are better than pure zinc coatings.
• Cut edge protection: Z275 provides pure zinc protection, but the repair speed is not as fast as AZ150.
• Cost: Galvalume solution is the initial cost, and the initial cost of ordinary galvanizing solution is 15-20% lower.
• Maintenance cost: After 10 years, Galvalume is maintenance-free, and Z275 may need 2 coatings. Galvalume saves 40% in total cost over 30 years.

The whole process of production

• Substrate treatment: cold rolled steel coil such as DX51D → alkali washing + pickling → annealing (700-850℃).
• Hot dip plating: immerse in 580-620℃ aluminum-zinc molten pool → air knife controls the coating.
• Cooling and solidification: air cooling/water quenching to below 40℃, the coating forms an aluminum-rich corrosion-resistant layer + a zinc-rich sacrificial layer.
• Post-treatment: passivation (chrome-free/chromized) + oiling/anti-fingerprint coating → slitting and packaging.
• Quality inspection: coating thickness, plate thickness after rolling, surface flatness, bending test, stamping test, salt spray test, etc.

Export Packaging

• Plate material: wooden pallet + VCI anti-rust paper + wrapping film, waterproof film/desiccant for sea transportation.
• Coil & Strip material: VCI paper + PE film + steel guard ring, aluminum foil + “#” shaped steel belt for sea transportation reinforcement.
• Marking: Mark the material/weight/protection mark.
