Standard Features:
• Sealed Ball Bearings: Self-aligning and allow lasting free rotation.
• Drum Assembly: The counter balancing mechanism is housed in this unique, roll-up assembly.
• Maximum Security: All slats are manufactured from the highest quality galvanized steel with a baked enamel finish, to form an effective secure curtain. Two slide bolt locks standard on all doors. (Available in 24 or 22 gauge.)
• Weather Seal: A blade astragal made from E.P.D.M., a highly resilient and flexible rubber compound, runs the full length of the bottom angle to seal the threshold of the opening. This forms a barrier against weather, dirt, insects and rodents.
• Guides: Two pieces roll formed steel guides standard on all standard doors. Windlocks provided on larger sizes.
• Chain Operation: A minimum of a 4 to 1 reduction standard on all doors. Smooth hand-chain provides safe and comfortable operation eliminating the sharp edges common to lock link hand chain.

• The Porvene Secret: State of the Art technology has allowed Porvene Doors to create a Door Dynamometer which accurately measures the torque characteristics of roll-up doors.
Since 1968, the Company 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.
