Stainless Steel Frames
NCHM’s DEFENDDOOR stainless steel hollow metal
frames are manufactured with 16 or 14 gauge type
304 or 316 in typical No. 3, 4 (satin) or 2b mill
finishes.
Each frame-profile is formed on a brake press for
added strength and stability. The head and jamb sections
are assembled with a tab-and-slot arrangement
to ensure accurate alignment of the corner miters.
The face of each frame is continuously welded
and hand polished to match the original exterior
stainless steel surface. |
