Brand credibility: The key factor affecting the life of a sliding door is the pulley. The design of the big brand's pulleys is about 15 years, and the pulleys of some counterfeit products may break down in 2-3 months, which seriously affects the use of sliding doors .

Door frame material and door panel thickness: At present, the frame materials used for sliding doors on the market are carbon steel materials, aluminum-titanium alloy materials, etc., among which aluminum-titanium alloy materials are the most durable; secondly, depending on the thickness of the door panels, it is best to choose plates of 10mm or 12mm thickness. This is stable and durable when used.
Track positioning and damping devices: High-quality sliding door hardware is mainly reflected in the design and manufacture of the pulley system and the track, and the perfect combination of the two, the track is crucial. The quality of the track depends on the fact that it must have a curvature that can be matched with the pulley. It should be reminded that the good track is excellent in the strength design and the smoothness of the contact surface with the pulley, not the thicker the track wall, the better. In addition, it is necessary to pay attention to whether the product has a stop block and an upper and lower rail positioning system, whether there is a glass anti-collision strip, whether the bearing type pulley is smooth and silent when pushed, whether a shock absorption system is placed in the bottom wheel, whether there is a door height adjusting device, etc. .
The door spacing is no more than 5 mm: in order to ensure that the two doors are staggered and closed, all sliding door products will have a gap. The general external pulley requires a spacing of 15 mm, which affects the sealing of the sliding door. Although most products have tops, the gap between the tops used in different products and the gap size is still relatively large.
Bottom wheel load-bearing capacity and flexibility: The pulley is the most important hardware component in the sliding. At present, the pulleys on the market are made of plastic pulleys, metal pulleys and fiberglass pulleys. The fiberglass pulley has good toughness, wear resistance, smooth sliding and durability.
Tubular Picket Ornamental Fence
A tubular picket fence is a type of fencing that is made up of vertical pickets or posts that are connected by horizontal rails. The pickets are typically made from tubular steel or aluminum, which makes them durable and resistant to rust and corrosion. The fence is designed to provide a secure and attractive barrier around a property, while also allowing for visibility and airflow.
Tubular picket fences come in a variety of styles and designs, including traditional, contemporary, and ornamental. They can be customized to fit any landscape or architectural style, and can be painted or powder-coated in a range of colors to match the surrounding environment.
One of the main advantages of a tubular picket fence is its strength and durability. Tubular picket fences are commonly used in residential, commercial, and industrial settings. They are often used to enclose swimming pools, gardens, and outdoor areas, and can also be used for security and privacy purposes.
