Product Details
18 gauge aluminum sheet refers to a specific thickness level in the aluminum sheet measurement system. It is widely used in industrial fabrication, construction, transportation, and general engineering applications where a balance of strength and formability is required.
As a professional aluminum supplier, we provide a full range of aluminum sheet thicknesses, ensuring stable quality, competitive supply conditions, and reliable processing services.
What Does 18 Gauge Mean?
Gauge is a traditional thickness measurement system used for sheet metals. For aluminum:
- 18 gauge ≈ 1.0 mm thickness (approximate value depending on alloy standard)
This thickness is considered:
- Medium-light sheet
- Easy to form and process
- Widely used in fabrication industries
Professional Supply of Aluminum Sheet in Different Thicknesses
We specialize in supplying aluminum sheets and plates in a full range of thicknesses, including:
- Thin sheets (0.2 mm – 3 mm)
- Medium sheets (3 mm – 6 mm)
- Heavy plates (6 mm – 100 mm+)
Available alloys include:
- 1050 / 1060 / 1100 (pure aluminum)
- 3003 / 3005 (general purpose alloys)
- 5052 / 5083 / 5754 (marine grade alloys)
- 6061 / 6063 (structural alloys)
- 7075 (high-strength aerospace grade)
