Hard Tonneau Covers
In general, a hard pickup tonneau cover can be a one-piece lid which is moved upwards by gas struts (a lift up), or a slat construction that is retracted by means of rolling up (roller shutter) or folding (such as tri-folding). Sturdy aluminium/alloy slats or rigid vinyl give the roller shutter and folding types of pickup tonneau cover structure, strength and security.
