Tolok aluminium, commonly referred to as the “tolok” daripada aluminium, is a measurement of the thickness or diameter of aluminum sheet or wire. It is a common method of specifying the thickness of aluminum materials and is used in a variety of industries, termasuk pembinaan, pembuatan, and metalworking.

In the United States, aluminum specifications are usually expressed in numerical values, ranging from lower numbers to higher numbers. The higher the gauge number, the thinner the aluminum sheet or wire. Sebaliknya, lower gauge numbers indicate thicker aluminum material. Sebagai contoh:
12 gauge aluminum is thicker than 16 tolok aluminium.
18 gauge aluminum is thinner than 14 tolok aluminium.

What is the thickness indicated by the aluminum gauge? Take a 12 tolok kepingan aluminium sebagai contoh. How many inches is 12 tolok aluminium?
Ketebalan daripada 12 gauge aluminum plate is approximately 0.0808 inci atau 2.05 mm.
