3003 h22 aluminium diamond sheet bright finish forms an embossed pattern similar to the shape of a diamond on the surface of aluminum plate through rolling process. This pattern is not only beautiful, but also increases friction and reduces the risk of sliding, so it is widely used in stair treads, flooring, wall decorations, etc. 3003 aluminum, which is an aluminum-manganese alloy, has excellent rust resistance, corrosion resistance and formability, and is suitable for welding and complex processing. H22 temper denotes the state after heat treatment and cold working, with certain strength and toughness. The surface is polished or rolled to give a high glossy luster, suitable for decorative or high-precision requirement scenarios.

Processing technology of bright finish 3003 h22 aluminium diamond sheet:

- Pattern embossing

Adopting high-precision embossing rollers (roll surface hardness HRC60-62), the “diamond”-shaped pattern is pressed into the surface of the 3003 aluminum sheet through cold rolling process, with a depth of 0.8-1.2mm, and an accuracy of ±0.1mm for the spacing of neighboring patterns, to ensure the anti-slip performance and visual consistency.

- Annealing control

H22 state through 320-360 ℃ intermediate annealing treatment, eliminating cold work hardening stress, so that the hardness is reduced to HB50-60, easy to follow the bending (minimum bending radius ≥ 1.5 times the thickness of the plate) without cracks.

- Surface protection

Coated with PE protective film before leaving the factory, thickness 0.05mm, temperature resistance 80℃, to avoid scratches or oxidation during transportation and storage.

Advantages of 3003 aluminium diamond plate bright finish:

- Light weight and high strength: the low density of aluminum alloy can effectively reduce the weight of the product while maintaining high strength.

- Corrosion resistance: 3003 aluminum alloy has excellent corrosion resistance and is suitable for use in wet or corrosive environments.

- Ease of processing: It can be processed in various ways, such as cutting, welding, bending, etc., which is convenient for manufacturing and installation.

- Aesthetics: The glossy surface and unique fingerprint pattern design make the product appearance more attractive.

Application of 3003 h22 aluminium diamond sheet bright finish:

- Industrial anti-slip field

Applied to ship decks, oil drilling platforms, cold storage floors and other scenarios, the raised height and distribution density of the fingerprint pattern (about 2,000 pattern points per square meter) can provide a static friction coefficient of ≥ 0.75 anti-slip effect.

- Decoration Engineering

In building curtain wall, elevator car, indoor ceiling and other scenes, the combination of glossy treatment and pointer pattern combines modernity and functionality, and can replace part of the stainless steel material, reducing the cost by about 40%.

- Special equipment

Used in mobile access platforms, mining equipment pedals and other scenes, 3003 alloy lightweight characteristics (density 2.73g/cm³) compared with carbon steel weight reduction of 60%, while the corrosion resistance to meet the C5-M high corrosion environment requirements.

In summary, 3003 h22 aluminium diamond sheet bright finish is a building material with both aesthetics and practicality, and is suitable for occasions where corrosion resistance and formability are required, and where it is desired to increase surface friction to prevent sliding. This kind of aluminum diamond plate has a wide range of applications in building decoration, transportation equipment, industrial manufacturing and other fields because of its characteristics.
