SDI CERTIFIED means DCI is Certified for Quality

DCI is now among the elite few who have earned this special accreditation.

Quality is critical when it comes to hollow metal steel doors and frames… and now you know exactly what you are getting when you specify them!

To remove the mystery, the Steel Door Institute developed an industry certification called SDI Certified. DCI earned this certification by undergoing an extensive audit to confirm they meet rigorous manufacturing, performance and quality standards. By referencing DCI in a specification, design professionals can now be assured their doors and frames meet the highest standards in the industry.

In addition to standard hollow metal doors, SDI Certified doors by DCI include the following specialty doors and frames:

  • Blast Resistant
  • Bullet Resistant
  • Fire Rated
  • Lead Lined
  • Sound Control (STC)
  • Stainless Steel
  • Temperature Rise
  • Tornado Resistant

Many manufacturers claim to meet SDI standards. DCI became SDI Certified and proved it. Choose DCI for quality steel doors and frames.

The DCI Difference

Experience, Team and Processes

  • For over 35 years, DCI has met or exceeded all Industry specifications for hollow steel doors and frames. This has always been our normal operating procedure
  • DCI has an established workforce with the skills necessary to get the job done right and on time. Numerous DCI team members have over 20 years of experience manufacturing hollow metal doors and frames
  • Our state-of-the-art manufacturing facility was configured from the ground up to facilitate a “lean manufacturing process” – a method of delivering the exact amount product on time, exactly when it is needed

Superior Parts and Materials

  • Reinforcements: DCI has always manufactured reinforcements in-house for quality assurance and convenience. If a spec requires a special reinforcement, it’s ready when the doors or frames are scheduled to ship – no delays
  • Steel Gauge: DCI only uses steel with the heaviest gauge values, so customers have no doubts what they are installing on a job site
  • Galvanneal Coating: DCI provides optional galvanneal coating (Jetcote) for each door and frame at no extra charge to prevent rust or corrosion
  • Prime Paint: DCI uses specially formulated, low VOC paint that adheres to galvannealed steel extremely well – forming a hard shell coating that readily accepts final painting

Innovation and Quality

  • Among other proprietary door and frame systems, DCI has the only patented sound transmission control (STC) door in the Industry. Its standard thickness of 1 ¾" makes it the most versatile STC door available. Whatever the sound rating, the door’s lightweight design allows installation with three 4.5” butt hinges – while meeting ADA and entry pull requirements.
  • DCI stainless steel doors and frames are top-shelf in appearance, workmanship and quality. All parts for stainless steel doors and frames are fabricated in house from the same high-quality stainless steel as the doors to ensure that quality is never compromised.
