Why do we use aluminum profiles as guide rails?

Because as a rail, the surface must be smooth so that lubricants can be used to allow smooth passage of machinery and equipment, etc. Aluminum alloy is extruded and then anodized. Aluminum alloy is extruded and then anodized, the surface is very smooth, as a guide rail of choice. And aluminum alloy profile hardness, good aluminum profile manufacturers processing accuracy is particularly high, in full compliance with the requirements of the high precision level. Furthermore, aluminum alloy can be extruded into a lot of complex cross-section profiles, according to the contact surface of the equipment to design a more tailored to the actual cross-section.
