Construction Standard

BUILT TO PHARMACEUTICAL-GRADE STANDARDS

Clean room doors aren't standard doors. Every joint must be crevice-free to prevent microbial harborage, welds must be continuous and ground smooth, and the finish must withstand repeated chemical cleaning without corroding or pitting.

We fabricate from 304 and 316L stainless, with 316L recommended for areas with aggressive cleaning protocols or high-moisture environments. All welds are TIG, all ground smooth, all finished to your specified standard.

  • 304 or 316L stainless grade
  • Hygienic continuous TIG welds
  • Crevice-free frame construction
  • #4 brushed finish
  • Custom opening dimensions

Frames & Jambs

CUSTOM FRAMES FABRICATED TO YOUR EXACT OPENING

No standard frame sizes. Every frame and jamb is fabricated to the exact rough opening dimensions from your project drawings. Wall thickness, reveal depth, hardware strike locations — all incorporated at fabrication so your team installs, not adapts on site.

For multiple openings on the same project, we batch-fabricate to keep lead times tight and pricing consistent across your order.

Finish Options

#4 BRUSHED — YOUR SPEC

The #4 brushed finish is the clean room industry standard — consistent directional grain, easy to clean, and visually appropriate for controlled environments. For the most aggressive sanitation requirements, we remove the microscopic surface peaks that harbour bacteria, producing a mirror-bright surface with the lowest possible bacterial adhesion.

  • #4 brushed (industry standard)
  • Mill finish on request
  • Consistent finish across batch
  • Chemical-cleaning resistant
