Rockarmor’s super rack, or better known as the full length rack, was originally designed back in 2006 for those 4wdrivers planning to drive heavily corrugated tracks like the Simpson Desert and parts of the Kimberley where a strong solid roof rack was needed.
“In 2014, a massive influx of cheaper racks were introduced into the Australia market by other retailers, this saw Rockarmor’s roof rack sales drastically drop in numbers, and it just wasn’t in Rockarmor’s interest to manufacture the rack. However in 2018 a call for a better quality steel roof rack was being requested again by the 4wd public and Rockarmor decided to once again re-introduce its super rack back into the market”.
To avoid corrosion, most vehicle owners would choose to use a alloy rack, though if you have driven on these tougher tracks, you would of seen or heard the many stories of bent alloy roof racks on the side of the road where they just haven’t stood up to the test.
These days, most steel racks you will find in stores will be very cheap however, these “cheaper” racks can rust very quickly. To avoid corrosion, Rockarmor exercise a few extra steps during manufacturing process, making sure the rack will not corrode and last you a much longer time, then those cheaper steel racks.
The Manufacturing Process:
When manufactured, the Rockarmor super rack goes through 3 very important manufacturing stages, which include; Sandblasting, E-coating & powder coating. After the rack goes through these 3 steps, each rack then goes through 2 tests, which include a salt spray test then a weight carrying capacity test.
What is E-coating?
The E-coat process is best described as a cross between plating and painting. It is a process where a metal part is immersed in a water-based solution containing a paint emulsion. An electric voltage is applied to the part causing the paint emulsion to condense onto the part.
A part can be painted both inside and out, wherever the liquid is able to reach a metal surface. The coating thickness is limited by the applied voltage. As areas of high voltage build a coating they become insulators thus allowing lower voltage areas to build up. Finally, the interior of a part can be coated since the exterior is fully insulated by the coating. Following the painting tank, a rinse tank removes the residual emulsion from the part and recycles it back to the paint tank by ultrafiltration.
The E-coat is cured by heat and the curing time and temperature is determined by the E-coat chemistry; epoxy, acrylic, etc. The preparation steps for E-coat are identical to plating steps in that the metal surface must be chemically clean.
The Super Rack Specifications and Features:
The roof rack has been designed with many handy features, advanced 4wdrivers require when driving long expeditions.
First of all you can’t look past the shear strength of the rack. The rack is manufactured from premium grade steel, which is then carefully welded together and then put through a 3 phase treatment process detailed previously above.
The roof rack gutter mounts have been rated to carry a whopping 500kg, which your vehicle’s roof will not carry, but you can have full confidence the rack will not bend on those harsh corrugated tracks, if you are wish to carry heavy items such a spare wheel, heavy fire wood etc.
The rack has a steel mesh floor welded into the base meaning you can even store smaller items which will not fall through the bottom of the rack. and has a number of handy features like cargo net hooks, front & rear antenna mounts plus pre drilled light holes.
