Since 1968, Porvene has been the leader in the continuous steel sheet door and has branched out into the Heavy Duty Rolling Steel Slat Door. In 1990 the Company introduced this product line with the same high standards that were used in the introduction of the continuous steel sheet door. The design and operation features of the slat door are superior within the industry and can meet the needs and requirements of most applications. The Company has also introduced a Rolling Grille and a Steel Backed Insulated Rolling Steel Door with the same high standards as its other products. In 2011, Porvene introduced a line of Commercial Sectional doors. The line includes Standard Lift, High Lift, Vertical Lift, and Insulated Steel Backed Doors.
