Steelcraft decorative doors feature deeply embossed panels on both sides. Six panel and eight panel designs are patterned after traditional high quality, wood panel doors, but add the durability, fire protection and long-lasting operation of steel doors. The polystyrene core with honeycomb around the perimeter gives Steelcraft decorative doors added strength and makes the doors energy efficient. Decorative doors are manufactured in either 20, 18 or 16 gage hot dipped A40 galvanealed steel, conforming to ASTM A653 specifications.
