What materials is the cover made of? How are they constructed?
THE BROAD FLAT SURFACE OF THE COVER: is made out of a hard and flexible material called "HARDCORE." Hardcore is an industial grade, flat, board-like material that is made out of a combination of compressed wood and synthetic materials. The backbone of the 4Way Tonneau Cover is a solid automotive composite panel that is completely encapsulated in a polyurea coating that is basically the same stuff used on "spray in" bedliners. The difference however is that the final texture is smoother. The benefits of this coating means:
1) No possible delaminating problems.
2) No possibility of warping.
3) Smooth finish makes the cover very easy to clean.
4) Cover will be virtually indestructible and will outlast the life of your truck!
The reason a 1/8" "Hardcore" panel was used instead of a heavier and thicker panel was because it was determined that this thickness of this panel had the perfect combination of the properties that we wanted....A RIGID, HARD, TONNEAU COVER that was SECURE, LIGHTWEIGHT, EASY TO HANDLE, and EASY TO REMOVE!!
EXTERNAL FRAME AROUND THE COVER: The external frames are constructed of 6105-T5 aluminum extrusions (patented design) and are powder coated satin black paint. Powder coated paint is extremely resistant to chipping and scratching so this ensures that the frame will look good for years to come.
SUPPORT FRAME UNDERNEATH THE COVER: The roof panel is supported by a series of aluminum roof bows that provide strong support and are lightweight. This cover is NOT designed to carry a load, however it is strong enough to support an evenly distributed snow load of approximately 200 lbs snow load.
MOUNTING RAILS (the rigid rails that are clamped to the truck): The mounting rails are also constructed of 6105-T5 aluminum extrusions (also patented design) and are also powder coated in a satin black paint.
ALUMINUM CLAMPS: The clamps are aluminum and are basically a G-Clamp which was designed specifically to lock into our mounting rails and to secure to basically any truck box design. As you will notice in the pictures, these clamps are extremely secure because they clamp downward to the top of the rail, and reach underneath the rail with opposing force, clamp upwards. This is the most secure clamping system on the market today.
THE LOCKS: The locks we use are Tubular locks. They are made entirely of "free machined" solid brass. The brass gives us the strength we need to hold the tonneau cover on the truck bed. Tests conducted by CompX Security Products have proved that the locks will not fail even with direct pressures exceeding 750 lbs. The Brass is extremely corrosion resistant and therefore greatly reduces the metal fatigue factors. Another advantage to tubular locks is that the key design eliminates broken keys in the locks.
