Roof rack (Roof Racks), also known as a roof rail or a roof rack, is fixed to the vehicle roof rail 2. The roof is equipped with all the basic scheme. Performance infrastructure for the entire roof equipped with roof program is essential, therefore, we believe it is necessary to do the roof rack product summary and comparison of a system. Birth of roof rack industry stems from the development of Western industrialization process, after World war II into the family car and gradually developed Western countries, and thus the demand for roof racks of the earliest produced in Western countries. But throughout the decades roof rack industry development history, we find that the development of this industry is very slow, the market demand is generated in about the 1950s, after half a century, until today, the first roof rack was developed to three generations of products.
1. The roof rack Precautions
1, attention roof rack to install the lock cylinder and key, and to ensure the use of locking.
2, do not overload the roof rack, cool roof rack marked bus carrying capacity of the car is designed to check their car’s instructions to determine the actual load weight.
3, aluminum alloy roof rack will not rust, but in use there will be slow oxidation, rain water or washing water containing an acidic or basic substance, also a certain surface erosion, a long time there will be a slight color spot, this is normal.
4, when mounting heavy items, or other hard metal objects likely to cause minor scratches on aluminum rail, is normal wear and tear.

6, frequently do not disassemble after installation, so that disassembly of ordinary car roof rack may adversely affect the paint; fixed point reserved for the use of the car for installation, frequently it is possible to detachably fixed point screw parts hurt, although removable roof rack are possible, but in the choice, choose to do long-term fixed roof rack. .
Optional roof rack 2
1, note that the maximum load can withstand roof rack:
Some brands nominal 75 kg or 100 kg, an actual carrying capacity but ultimately depends on the design of the carrying capacity of the roof, some models original design capacity of only 45KG or 50KG, although this is a very conservative data, but we still advise against overload.
This is cool on the bus roof rack is in place to do: directly to the car’s design carries the weight marked as carrying the weight of the roof rack, the humane point of view, although the surface appears to mark than other brands the carrying amount is lower, but in fact it is truly win the trust of customers, after all, safety is the first customerBit.
2, note that the compatibility of the roof rack.
It depends on the way the roof fixed equipment, old equipment bought years ago, probably only for the first-generation or second-generation roof rack, recently listed on the market or in the future the equipment can generally be used the second and third generation roof rack. Future fixed a long way in the T-slot and fixed ways common folders will always exist, and this is a common standard second-generation and third-generation roof rack.
3, attention windage wind noise.
more and more concerned about the drag of the riders wind noise issues with the process, the drag will increase fuel consumption, but also bring wind noise, a lot of first-generation and second-generation use of roof rack customers are fully understood, if you are sensitive to wind noise, ultra-quiet technology using direct selection roof rack.
4, compare the appearance and styling.
traditional roof racks are on both sides of the penetration-type design, the bar will extend from the roof to the sides, and some brand original style roof rack, like a car Customized Like, it can also be equipped, both beautiful and practical.
5, considering the future cost.
Some brands of roof racks are open to sell, rails, rack foot, fixtures and even the lock cylinder and keys are purchased separately assembled together, we would like to use in the future when the transfer is required several replacement parts and spent a lot of money, but some brands crossbar and frame feet are integrated design, and all roof rack comes standard with a cylinder, the width of the crossbar can be adjusted, which greatly facilitates the customer facelift models at different times.
change the future without having to change the foot frame, only need to replace the most suitable fasteners on it, although it can not get more profit in this part of the sales rack feet, but but a great convenience to customers. Cool off the foot gives adaptability to meet all installed fixtures, only one model is enough.
6, define their use.
If you use your car roof rack is mounted solely to work and hope that better mounting space, it is clear that on both sides through a conventional type of roof rack is more suitable for you, it has a larger mounting width. If you install the roof rack to carry the occasional roof rack and hope for long-term stay in the roof, both strong and beautiful, so not prominent on both sides of the roof rack is more suitable.
