There are many different styles of tonneau cover (or bakkie bin covers) on the market today and sometimes it can be hard to know which one is right for you. Choosing a tonneau cover isn't as easy as picking out a pair of side steps or installing a bug shield. Bakkie-bin covers are the best way to dress up your bakkie while also protecting your cargo. However, it's important to decide which one would work best for you?
Conventional wisdom used to say: “Drive your bakkie with the tailgate down and you’ll reduce drag and save gas. Better yet, just take it off and you’ll be lighter, too!” However, a study published through the Society of Automotive Engineers (SAE) seemed to prove that old conventional wisdom wrong.
The study found that driving with the gate down did not improve fuel efficiency at all—in fact, it actually made mileage worse. It turns out that a raised gate helps trap a “bubble” of air in the bin, allowing wind to flow over the vehicle. Further, the study found that a tonneau cover—even a partial cover over the rear end of the bin—can increase aerodynamics, reduce drag, and improve gas mileage by over a mile per gallon. Depending on which cover you choose, tonneau covers can accentuate a bakkie’s style, shield cargo against the elements, protect valuable items against damage, and even provide security against theft.
There are far too many choices and factors involved to make an uninformed decision. When picking a tonneau cover you should consider your budget, how you use your bakkie and the type of look you want. The first thing you should decide is whether you want a hard or soft tonneau cover.

Hard Tonneau Covers
Hard bakkie bin covers, or rigid bin covers, are generally

party or on a hunting trip, the entire party could use your
hard cover as seating.
Popular Styles of Tonneau Covers in South Africa
Traditional Basic Soft Tonneau Covers
Soft roll-up/string tonneau covers consist of a soft vinyl cover material that sometimes lays over a set of aluminium/steel bows and secures to the J hooks on the outside of bin. When detached from the frame, the cover rolls or folds up and usually secures close to the cab in the form of a slide-in strip which makes it slightly difficult to install and/or remove the cover. Issues that do occur are the strings breaking or that it wears out. The material normally used is an inexpensive type vinyl which can easily tear and fade. It scuffs & eventually allows water through. Replacements on this inexpensive type vinyl’s are at regular intervals. Above all does it offer no security at all.
Fold & Snap Clip-on Frame tonneau Covers
A variation of typically fold and snap clip-on frame tonneau covers are among the average priced tonneau covers currently available. They come in both roll-up and foldable designs and generally consists of a soft vinyl cover material that lays over a set of aluminium/steel bows and secures to an aluminium frame using snaps, Velcro, or a belt rail. These type covers might have a sleek look and feel to it, but it bulges due to the steel bows and decreases your fuel efficiency.

Hinged Hard Tonneau Covers
Hard hinged tonneau covers are amongst the more expensive cover options as it features a rigid fiberglass or composite cover material, which clamps to the frame rail.

They also typically utilize shocks or a set of gas struts that assist in the opening of the cover due to the excessive weight, giving you quick, access to cargo. Like traditional hard covers, hard hinged covers offer the necessary security but are not removable after installations. The gas strut eventually loses its ability to keep the cover in the upright position.

The housing reduces your bin space, especially on a double cab type bakkie. These type roller shutter covers offer good security for valuables locked in your bin, it also offers good fuel efficiency due to its somewhat sleek design.
