Affordable Multiples™ is manufactured from CNC manufacturing equipment that produces modular ceiling panels quickly and with precision. Computer-controlled CNC machinery reduces the production time and lowers the cost of metal ceilings. Finishes Ceilings Plus offers a wide variety of finishes applied to aluminum. Ceilings Plus will explore unique finish selections by the request of the architect. Consult factory for possibilities. Metal Ceilings Plus manufacturers from painted, anodized aluminum and stainless steel. Other unique metal finishes are available. See Metal Finishes.
