Steel thickness gauge
More often than not we face find that sectional steel doors are being specified by steel thickness gauge numbers alone. This can lead to substantial discrepancies in strength, dent resistance, and durability. This is mainly caused by the fact that all and sundry have a different definition of “gauge”.
To solve this dilemma of steel thickness gauge, The Door and Access Systems Manufacturing Association (DASMA) are coming to the aid. They are hoping that specifying sheet steel by minimum decimal thickness will aid assured functioning of sectional overhead doors. DASMA lately finished a new specification sheet that will be used as a standard within the garage door industry when specifying steel thickness.
In the metal working industry, the number of ounces per square foot of area or the weight of the steel defines gauge. This base definition applies to bare steel before any galvanizing, paint or other type of coating. When galvanized steel is being considered, the steel thickness gauge is determined by adding the weight of the bare steel and weight of the galvanizing material.
Even as galvanizing attaches to the weight of the steel, it has modest consequence on the strength of the steel, and for the reason that galvanizing is an applied coating, the actual steel thickness of the 24-gauge material could differ as much as the coating thickness varies.
In addition to the discrepancy of the weight measurement weighing a square foot piece of steel is not convenient in today’s manufacturing situation, thus, the weight measure is transformed to a more functional form- decimal thickness.
The mathematical process gives us the theoretical decimal thickness for each gauge of material. The theoretical thickness cannot be maintained accurately in the steel forming procedure; as a result, AISI has recognized a tolerance range for each gauge.
Manufacturers that make use of sheet steel on average order the material by the desired decimal thickness, not the gauge number. The decimal thickness is frequently ordered to the minimum acceptable to the customer. Some customers, on the other hand, indicate the “nominal” tolerances that can be used. Now, here the discrepancy comes in as the word “Nominal” is pretty much used loosely. So if you are purchasing a 24 gauge, then is reality the customer is getting the gauge with 24 gauge name. The steel thickness gauge would be having a tolerance in decimals.
