SHEET METAL PRODUCTS MFG. — shop only — N.O.C.
This classification applies to the manufacture of sheet metal products, including but not limited to brackets, chassis, panels and covers when more than 50% of the metal used is #15 gauge or lighter and metal stamping payroll, if any, does not exceed 10% of the total manufacturing payroll. If 50% or more of the metal used is #10 to #14 gauge, or if more than 50% of the metal used is #15 gauge or lighter and metal stamping payroll exceeds 10% of the total manufacturing payroll, operations shall be classified as 3400, Metal Goods Mfg.
Metal stamping is defined as the operation of power-driven presses or brakes and foot- or hand-power presses or brakes used for blanking, forming, trimming, drawing, punching or assembling metal where the operator places each piece under the point of operation at each complete press or brake stroke.
Operations performed on power presses that may be interchangeably hand fed or automatically fed shall be considered as metal stamping.
Metal stamping does not include (1) rotary punches, whether computer or manually controlled, which require only the loading and unloading of the work piece by the operator and does not require the operator to place or reposition the work piece after each stroke, or (2) hydraulic presses or brakes where the ram travel will automatically stop upon release of the activating mechanism.
Sheet metal products assignable to this classification include but are not limited to heating, ventilation and air conditioning duct work; electrical and electronic chassis and enclosures; metal musical instruments; and kitchen and restaurant equipment such as sinks, steam tables and overhead hoods.
The shop fabrication of sheet metal products in connection with installation, construction or erection operations by the same employer shall be classified as 5538(1)/5542(1), Sheet Metal Work.
If more than 50% of the metal used is sheet aluminum, the operations shall be classified as 3066(3), Aluminum Ware Mfg.
If more than 50% of the metal used is sheet copper or brass, the operations shall be classified as 3066(4), Coppersmithing.
