3250 Series Overhead Door
Brand: DBCI
A Commercial, Heavy Duty, and Insulated Solution
Our DBCI 3250 Series commercial-grade steel door is built with superior, high-strength materials and is engineered to withstand moderate to high wind loads common in many coastal regions.
The 3250 Series features ribbed corrugation with an “L” shaped windlock design that grips in place under high pressure, and an 80-degree profile that makes installation fast and easy.
Insulated roll-up doors feature a steel curtain with flexible insulation material, such as mylar, that allows the door to open and close with ease. The insulation material is adhered to the interior skin of the door curtain to provide continuous insulation. To evaluate insulating properties of your roll-up door, check the R-value. The R-value describes the thermal resistance of your insulation material. The higher the R-value, the greater the effectiveness of the insulation.
