Composite Panel

Diamond Roll-Up Door was the first door company to produce a composite panel roll up door – The Diamond Evolution. This premium roll-up door has superior durability to wood and aluminum door products.

The Evolution Door obtains its strength and durability from its panels made from a steel outer skin and polyethylene core. The panel material increases impact resistance as well as being impervious to moisture. Diamond also created the tongue seal insert which in combination with groove in the adjoining panel creates a weather seal joint.

Over time where other roll-up doors swell, crack, break or jam when impacted the Evolution Door will maintain its operation and integrity. This durability significantly reduces maintenance costs.

Diamond will provide you with an engineered roll-up door solution to suit your application.
