Installation and maintenance specifications
Installation requirements
1. Before installation, check the size of the opening and the specifications of the door body to ensure that the verticality and flatness deviation of the opening is ≤ 5mm, and the reserved installation gap is 20-30mm; the installation surface of the track needs to be flat and firm, with a levelness deviation of ≤ 1mm/m, to avoid affecting the sliding of the door panel.
2. Frame fixation uses expansion bolts or chemical anchor bolts, with a spacing of ≤ 600mm, to ensure a firm connection with the wall or ground; the frame and the wall or ground are filled with polyurethane foam, and the outside is applied with weatherproof sealant to ensure waterproof and sealing.
3. The installation position of the hardware accessories and the pulley track is accurate, and they are firmly fixed; after the door panel is installed, the horizontal and vertical positions need to be adjusted to ensure uniform gaps between the door panels and smooth sliding, and a tight closing; the anti-detachment device needs to be installed in place to avoid the risk of door detachment.
4. Electric sliding doors need to be correctly connected to the power supply, debug the motor operation and remote control function to ensure coordinated movement; after installation, an opening and closing test needs to be conducted to check for no jamming, leakage, or abnormal noise before acceptance.
Daily maintenance
1. Avoid sharp objects hitting, scratching the profiles and glass, and prohibit drilling holes or cutting grooves on the door body (to avoid damaging the structure and sealing performance);
2. Clean the surface of the profiles, glass, and track regularly (every half year), use a damp cloth to wipe, avoid using strong acid or alkali cleaning agents; if there are any debris (such as dust, hair, small stones) in the track, it needs to be cleaned in time to ensure smooth sliding of the door panel.
3. The hardware accessories and pulley need to be regularly (every year) lubricated with oil to keep the opening flexible; if there is looseness or jamming, it needs to be tightened or replaced; if the sealing rubber strip is aging, cracking, or falling off, it needs to be replaced in time.
4. Avoid keeping the door body in a fully open state for a long time, especially in outdoor scenarios, to prevent damage to the door body components caused by strong winds and rain; when not in use for a long time, it is recommended to close the door panel and lock it, and take protective measures.

FAQ：
1. Are sliding doors and sliding-gate doors the same type of door? What are the differences?
Both belong to the same product category and are often used interchangeably in daily terms. The subtle difference lies in the structural design. Sliding doors usually refer to single-track/multi-track horizontal sliding door bodies, including lightweight partition doors, heavy-duty balcony doors, etc.; sliding-gate doors are more inclined towards double-track parallel sliding large-sized door types, commonly seen in balconies, shops, etc. The core is to achieve opening through a pulley track, without occupying additional space.
2. What are the reasons for the sluggish sliding or strenuous pushing and pulling of sliding doors? How to solve them?
The main reasons include track accumulation of dust or debris, wear and deformation of the pulley, and uneven installation of the door panel. The solution is: first, clean the dust, hair, small stones, etc. in the track; if the pulley has cracks or is stuck, replace it with the same model stainless steel nylon pulley; if the door panel is tilted, adjust the height of the upper and lower tracks or the adjusting screws on the side of the door panel to ensure the door panel is level.
3. Will sliding doors leak air or water? How to improve the sealing performance?
Qualified products are equipped with multiple sealing rubber strips. Under normal use, they will not leak air or water. Leakage is mostly caused by aging and cracking of the sealing rubber strips, uneven gap between the door panel, or blockage of the drainage holes in the track. You can replace the EPDM (triple rubber) sealing rubber strips, adjust the gap of the door panel to make it uniform, and regularly clean the drainage holes in the track; you can also install a bottom seal strip to further enhance the sealing effect.
4. How long does the sliding door's pulley last? Is regular maintenance required?
High-quality stainless steel nylon pulleys, under normal use and regular maintenance, can achieve up to 50,000 sliding times or more, with a lifespan of approximately 8-12 years. Regular maintenance is required. It is recommended to add lubricating oil to the pulleys and tracks every six months, and clean the track debris to avoid excessive wear of the pulleys.
5. Are sliding doors without lower tracks easy to use? Which scenarios are suitable?
Sliding doors without lower tracks have seamless ground connection, facilitating the passage of wheelchairs and baby strollers, and can avoid dust accumulation. They have higher aesthetics. They are suitable for indoor partitions (such as study rooms, cloakrooms), small-sized spaces; however, their wind resistance performance is slightly lower than those with lower tracks, and it is not recommended for use on high-rise balconies, outdoors, etc. in strong wind scenarios.
6. Can the glass of sliding doors be replaced? Is it unsafe if it breaks?
It can be replaced, and it needs to match the size and thickness of the door frame. The standard tempered glass breaks into blunt-angle particles, which will not fly and cause injury; if you are concerned about safety, you can upgrade to laminated tempered glass, which will have glass fragments adhered to the PVB film after breaking, providing higher safety.
7. Are sliding doors suitable for high-rise residential balconies? Is the wind resistance sufficient?
Yes, but you need to choose heavy-duty sliding doors. The requirements are that the profile wall thickness should be ≥ 1.6mm, and use an upper and lower double-track structure. The single pulley load should be ≥ 30kg. During installation, use expansion bolts to firmly fix the frame, with a spacing of ≤ 600mm. In coastal areas with strong wind, you can customize products with a wind resistance grade of ≥ 5 to ensure safety.
8. Can sliding doors be made electric? How to choose between electric and manual models?
Electric models can be made, equipped with a motor and remote control system, to achieve automatic opening and closing, and can also be equipped with a wind and rain sensor. Manual models have higher cost performance, are simple to operate, and are suitable for low-frequency opening scenarios in homes; electric models are suitable for large-sized, heavy door panels, or shop facades, and high-rise installations, with more effortless and convenient operation.
9. Will the color of sliding doors fade? What are the daily cleaning and maintenance precautions?
The surface of high-quality profiles is treated with powder coating or fluorocarbon coating, which has strong resistance to ultraviolet rays. Under normal use, it will not significantly fade for 10-15 years. Daily cleaning can be done with a damp cloth on the profiles and glass. Avoid using strong acid and alkali cleaning agents; do not scratch the surface of the profiles with sharp objects. Regularly check if the hardware components are loose.
10. What is the maximum size that sliding doors can be made? What should be noted during customization?
The standard single door width ranges from 600mm to 1200mm, and the height ranges from 1800mm to 3000mm. The total width of multi-track sliding doors can reach up to 6000mm. When customizing, the thickness of the profile and the load-bearing capacity of the pulley need to be selected based on the size of the door opening. For large-sized door bodies, it is recommended to choose broken-bridge aluminum profiles and heavy-duty pulleys. At the same time, the load-bearing capacity of the building opening should be confirmed to avoid affecting stability.
