Unique to our company, "diet" core provides more structure than a hollow core and less weight than a solid core. Discover how we make this material so versatile in the specification sheet.


Our Fire-rated commercial wood doors can have ratings for 20, 45, 60 or 90 minutes to meet building regulations. Read the spec sheets for our 20-minute fire-rated five-ply doors45-minute fire-rated five-ply doors and 60 & 90-minute fire-rated five-ply doors.
