MTL Fabrication


Fab Operating Hours

Mon - Thurs: 8:00am - 9:00pm
Fri: 8:00am - 6:00pm
Closed on weekends and holidays

Please note that the elevators and entrances to Building 39 are locked after 5PM! If you do not have a key to the building (key # 138B), you will not be able to enter the building or floors 2, 4, 5, and 6 (floor 3 will be accessible because it is handicapped-accessible). This is done because MTL is home to a lot of dangerous substances and thus this is done for the safety of all. Please obtain a key from the Operations Administrative Assistant if you plan to work in the fab after 5PM.

Note: Toxic gases are shut off approx. 1/2 hour before closing
