Door frames and door panels Key Aspect - Door frame material and door panel thickness
    At present, the sliding doors used in the market are carbon steel materials, aluminum and titanium alloy materials, including aluminum and titanium alloy material is the most durable; second to see the door thickness, sliding doors with wood, the best choice 10mm or 12mm thick plate , So that the use of stable and durable; thickness of less than 8mm, will appear thin, floating; 6mm below the thick door is easy to deformation, it is difficult to achieve the normal use of the request.
     Pulley key point - bottom wheel load capacity and flexibility
    Pulley is the most important metal parts sliding, at present, the pulley on the market materials are plastic pulleys, metal pulleys and glass fiber pulleys 3 kinds. Plastic pulley texture hard, but easy to break, the use of a long time will be astringent, hardened, push pull feel becomes very bad, metal pulley strength, but in contact with the track prone to noise; glass fiber pulley toughness, Grinding good, smooth sliding, durable.
    Track critical point - track positioning and shock absorber
     High-quality sliding door hardware accessories are mainly reflected in the pulley system and track design, manufacturing and the perfect combination of the two, the track is essential. The quality of the track depends on the fact that it must have a radian fit with the pulley. It is important to note that the good track is superior to the smoothness of the design and the smoothness of the contact surface with the pulley, not the thicker the track wall. At present, the sliding doors of the track are cold rolled steel track and aluminum alloy track two. Rails are not necessarily good, it should be said that good aluminum track in some ways better than rail, especially in the anti-noise.
     Also note that the product has no stop block and the upper and lower track positioning system, with or without glass anti-collision tape, bearing pulleys in the push is smooth when the silent, the bottom wheel is placed in the shock absorption system, whether the door height adjustment device The
     Seal the key point - the door interval does not exceed 5 mm
     In order to ensure that the two staggered, all the sliding door products will be spaced, the general external pulley needs 15 mm interval, this interval affects the sliding door sealing, especially Beijing wind and sand, a lot of dust intrusion opportunities.
     Although most products are added tops, but different products used in the top of the dense, gap size gap is still relatively large. Try to choose a small interval, the wool of the product, like the German A De Dai Ge sliding door spacing of only 5 mm, coupled with high density of the top, basically put an end to the invasion of dust.
     Life Critical Key Aspect - Brand Credibility
     The key factor affecting the life of the sliding door is the pulley. Large brands of pulleys designed to use for about 15 years, and some counterfeit products pulley 2-3 months may be broken, which seriously affected the use of sliding doors.
