Cycle rack is a kind of metal rack mainly used for parking bicycles. Public places generally have special bicycle parking racks for citizens to park when they travel. Considering the short and long term bicycle parking rack, indoor and outdoor, individual and public needs, bicycle parking rack has a variety of materials to choose from, the main materials are iron pipe, stainless steel, carbon steel and aluminum alloy.

Materials for Cycle Rack

Iron pipe
Cycle racks made of iron pipe was widely used in the early days, because of its relatively low cost, but the corrosion resistance and rust resistance of iron pipe is poor, the service life is short, the rust of iron pipe will seriously affect the environment of the use of origin, so now on the market basically rarely see bicycle parking rack made of iron pipe.

Carbon steel
When it comes to carbon steel, it is relatively easy to rust, but carbon steel is indeed very wear-resistant, such a property, can be used to fix structural objects, so that it will be stronger. The most commonly used frame on the market now should be made of carbon steel. The service life of carbon steel bike racks after galvanized pipe plastic spraying process can reach about 20 years. The use of hot dip galvanized rust prevention, high temperature spray baking spraying process can effectively prevent oxidation and rust of products in outdoor use. So by the majority of users like and favor.

Stainless steel
The corrosion resistance of stainless steel products is beyond doubt, and it has the advantages of heat resistance, high temperature resistance and low temperature resistance. Secondly, the physical properties of stainless steel material are stable, not easy to deformation, is very suitable for manufacturing outdoor public parking rack materials. The bicycle parking rack made of stainless steel has the appearance of high-grade atmosphere, long service life, and it will not rust. At the same time, the surface of stainless steel can show rich and gorgeous color after surface treatment, so that it can meet the decoration needs of many occasions. The maintenance of stainless steel products is very simple, as long as it is not used in particularly serious pollution places, the general maintenance is relatively low cost, and the cleaning is relatively simple. But because the price of stainless steel itself is expensive, so the cost is very high, which makes some users can settle for the next choice of 235 carbon steel rack. So, in sufficient budget, stainless steel cycle rack is definitely the first choice.

Aluminium alloy
As we all know, the first major advantage of aluminum alloy is its light weight and high strength. Its weight is only one third of iron, steel and copper, but its hardness is several times that of them. The lightweight aluminum alloy frame is not only easy to handle, but also cheaper to transport; Double parking frame made of aluminum alloy material, high hardness can resist tension and greater impact force, can reduce the weight of the frame, convenient parking bicycles, women and the elderly can easily use. At the same time, the use of aluminum alloy has high bending strength, profile concave and convex, made of parking frame lightweight and beautiful.

Aluminum alloy surface after anodic hydrolysis treatment, can show a variety of colors, can be selected at will, after the hydrolysis of bright and shining, its unique advantages can be applied to a variety of different surface polishing skills, more widespread paint, powder coating, anodic oxidation, electrophoresis. The appearance of the most lubricated powder coating can protect against UV light, the frame is difficult to remove paint, easier to maintain, basically no repair can keep bright luster for a long time, powder coating is not only used, but also has a variety of colors to choose from. Aluminum alloy bicycle frame corrosion resistance is strong, do not fade, do not crack, for details, you can look at this aluminum alloy automatic two tier parking rack.

Surface treatment of bicycle parking rack

Galvanizing - Hot Galvanizing/Cold Galvanizing

The role of galvanizing is to prevent steel frame rust, steel in the natural atmosphere is easy to rust. While zinc is not easy to change in dry air, it will form a dense zinc carbonate protective film on the surface in wet environment, which can effectively protect the frame. Our frame surface galvanized generally provide hot galvanized and cold galvanized for customers to choose.

Hot dip galvanizing: also known as hot dip zinc and hot dip galvanizing: it is an effective way of metal anticorrosion. It is to melt the zinc ingots at high temperature, put some auxiliary materials in, and then dip the metal structural parts into the galvanized groove, so that the metal components are attached with a layer of zinc layer, so as to play the purpose of anticorrosion. The advantage of hot dip galvanizing is that its anticorrosion ability is strong, the adhesion and hardness of galvanized layer is better, so as to play the purpose of anticorrosion.Hot dip galvanizing is a chemical treatment, which belongs to electrochemical reaction. Hot dip galvanized pipe is made of molten metal and iron matrix reaction to produce alloy layer, so that the matrix and coating two combination.

Cold galvanizing: is electric galvanizing, the amount of zinc is small, only 10-50g/m2, is the use of electrolysis to make the surface of metal or other materials attached to a layer of metal film process. The formation of uniform, dense, good bonding metal layer process can play a role in preventing corrosion, improving wear resistance, electrical conductivity, reflective and improve the appearance of the role. Cold galvanizing is a physical treatment, just brush a layer of zinc on the surface, so the zinc layer is easy to fall off.

You're still wondering which one to choose?

The appearance of hot-dip galvanized is not as fine and bright as that of cold galvanized, and the coating is uniform. But the thickness of zinc layer is dozens of times that of cold galvanizing. The corrosion resistance is also dozens of times that of galvanizing. Therefore, for outdoor bicycle racks used for a long time, we recommend the use of hot galvanizing, cold galvanizing can only be plated on one side, hot galvanizing should be fully plated. And hot galvanizing generally galvanized layer is thicker than cold galvanizing, so the price of hot galvanizing is higher than cold galvanizing.From the point of view of environmental protection, hot dip galvanized square pipe has less pollutant emissions, mainly the waste acid of pickling workpiece.
The pollutants of cold galvanizing mainly include waste acid of pickling workpiece, waste electroplating liquid, waste passivation liquid and so on. Discharge type and quantity are much more than hot galvanizing.

Stainless Steel Treatment - Polished/Brushed

Long-term dirt deposition will make the stainless steel parking frame rust and cause corrosion, but after surface polishing of bright stainless steel pipe parking frame, the appearance of bright bright and easy to clean, there is a layer of invisible protective film, can prevent the surface of the pipe corrosion, and not easy to accumulate scale. But the bright tube has a problem to pay attention to is that the surface is easy to scratch, will be scratched by sharp items will leave scratches, very affect the appearance, but stainless steel wire drawing tube is not to worry about this problem.

The advantages of matte surface drawing surface treatment are elegant appearance and atmosphere, and less light pollution; The disadvantage is that the surface of the steel pipe is less than a layer of protective film. The anti-rust ability of such a bicycle parking frame is reduced, so it is only suitable for some environments where the corrosion of the pipe is weak, such as indoor garage or shed.

Powder Coated

The surface coating can protect the bicycle parking frame from corrosion by water, rain, wind and other media. The coating sprayed on the shelf is a convenient and reliable protection method, which can not only protect the frame but also extend its service life. This finish is usually available in a wide range of colors. This finish is usually available in a wide range of colors. The bicycle parking rack is painted with various colors, shiny and glorious, which can beautify the street environment and make the users happy.

Having a cycle rack is one of the easiest ways to organise your bikes. It will make it easier to find them when you need them, and it will also prevent your bikes from getting damaged.More questions,we're online 24 hours!
