The difference between the national standard production line aluminum and national standard of industrial aluminum
the difference between the national standard production line aluminum and national standard industrial aluminum national standard and European standard line industrial aluminum section contrast figure 1 'first weight is different, generally speaking, even if the thickness of the same size industrial aluminium profile, aluminum the target profile will profile material supplies more than the target, which is heavier weight for example: size 40 * 40 * T3. 0 aluminum [ National standard] Section 10. 3 kg / 6 meters, and [ European standard] 13 the profiles of weight. 4 kg / 6 meters, weight is 3. 1公斤。 2, look from the exterior, oubiao profiles more beautiful and easy. Profile edge chamfer, gb profiles four corners chamfering small, basic is a right Angle. Oubiao profiles four edges have larger arc Angle, not easily damaged. 3 'groove is different, different fittings used in profile fixed connection ( Right Angle 90 degrees and a word connect 180 degrees) When placed different slot bolt, industrial aluminum nut. Gb aluminum tank placed ordinary square nut, oubiao aluminum tank placed special T bolts and T type nut. As shown: 5050 European standard profiles and gb 4040 profiles of assembling sketch the standard aluminium profile with gb aluminum biggest difference lies in: groove type, fixed connection in aluminum profile box placed different nut. Gb profiles groove placed ordinary square nut, industrial aluminum oubiao profiles should be placed special nut. Aluminum edge chamfer, gb profiles four corners chamfering small, basic is a right Angle. European standard profiles four edges have larger arc chamfering. National standard and European standard assembly line industrial aluminum assembly drawing comparison above for the standard assembly line aluminum and industrial aluminum gb production line of aluminum in detail. There are total of non-standard assembly line industrial aluminum profile, with the national standard is the difference between the thickness of the aluminum surface oxidation film do not meet national standards.
