Packing & Delivery

Transparency here reduces post-purchase inquiries. List package contents (e.g., product, USB-C cable, multilingual manual, warranty card) and highlight sustainable packaging (e.g., "100% recyclable materials"). Clarify shipping timelines by region (e.g., "EU: 5–7 business days," "APAC: 10–15 business days") and costs (e.g., "Free shipping on orders over $50"). State customs/duty responsibilities (e.g., "Duties calculated at checkout") and offer damage protection (e.g., "Free replacements for shipping-damaged items"). Add tracking instructions or icons (e.g.,) for clarity.

FAQ

1.What is "structural grade steel"?

Carbon steel labeled by numerical grades, including carbon structural steel (e.g., Q235) and high-quality carbon steel (e.g., 45#), with grades reflecting carbon content or basic mechanical properties.

2.Common grades and features?

20#: Low carbon, good plasticity/weldability (stamping/welded parts).
45#: Medium carbon, balanced strength/toughness (shafts/gears).
65#: High carbon, good elasticity (springs).
Q235: Cost-effective, for construction/ordinary parts.

3.How to choose the right grade?

Stamping/welding: Low carbon (20#, Q235).
Load-bearing parts: Medium carbon (45#).
Springs: High carbon (65#).
