The primary purpose of ceiling grid tees is to provide structural integrity to the ceiling system. This grid framework supports the ceiling tiles while allowing for easy access to plumbing, electrical wiring, and HVAC systems that may run above the ceiling. In commercial spaces, where maintenance and access to utilities are critical, this feature is invaluable.

Fire Resistance


HVAC access panels are openings in ceilings or walls that provide easy access to HVAC components, such as ductwork, valves, piping, and electrical connections. These panels are designed to facilitate regular inspections, maintenance, and repairs of HVAC systems without the need for extensive construction work. By simply removing the access panel, technicians can quickly reach the necessary components, ensuring that the system operates efficiently.


Fire-rated ceiling access doors typically feature a frame and panel system designed to resist fire exposure. The door is often lined with intumescent materials that expand when exposed to heat, creating a tight seal and further enhancing its fire-resistance capabilities. The fire rating of a door, which can range from 30 to 90 minutes or more, indicates the length of time it can withstand flames and heat.
