FAQ

What is the load-bearing performance of aluminum alloy folding doors?

Excellent load-bearing performance, not easily sagging or deforming after long-term use. Adopting thickened high-strength aluminum profiles, the door leaf is equipped with reinforcing ribs inside, and is paired with heavy-duty load-bearing folding hinges. The load-bearing capacity of a single door leaf can reach over 30kg; The track is made of thickened stainless steel material, which has strong load-bearing stability. After strict fatigue testing, it can maintain structural stability for a long time under normal household use without sagging or deformation problems

Good sound insulation effect can effectively isolate daily environmental noise. The door body adopts a 40mm thick aluminum profile and a multi cavity structure, matched with hollow tempered glass and high elastic sealing strips. The door leaves are tightly adhered between each other and between the door leaves and the track, with a sound insulation volume of ≥ 38dB, which can significantly reduce the sound of the living room TV, the closing sound of the kitchen range hood, the outdoor noise of the balcony, etc., meeting the daily home sound insulation needs

Folding smoothly without any jamming, there is no obvious abnormal noise during normal use. We use high-precision silent folding hinges, with built-in bearing structures and low opening and closing resistance; The track is finely polished and equipped with smooth pulleys, making it easy to fold and unfold the door leaf when folded; At the same time, there are anti-collision buffer rubber strips between the door panels, which can reduce friction noise during folding and improve the user experience

The core differences between different fan numbers lie in the opening width, folding space, and ease of use, which have a significant impact on the user experience. 

  • 3-4 panels: Suitable for door openings with a width of 1.5-2.5m, occupying small space when folded, flexible to open, suitable for kitchens and cloakrooms; 
  • 5-6 panels: Suitable for door openings with a width of 2.5-4m, with a wide passage after opening, good lighting, and suitable for connecting balconies, living rooms, and dining rooms; 
  • 7 or more: Suitable for large-span doorways (over 4m), such as villa terraces, requiring heavy-duty hardware to ensure structural stability; The more fans there are, the thicker the folded product will be, and sufficient storage space needs to be reserved
Can I customize an aluminum alloy folding door with a wide door opening at home?

Can be customized, supporting exclusive customization of large-span door openings. The standard customization range is door opening width of 1.2-6m and height of 2-2.4m. If the door opening size exceeds the standard range (such as width>6m and height>2.4m), free on-site measurement services can be booked. Designers can customize reinforced profiles, exclusive hardware, and fan allocation plans based on the door opening size, wall structure, and usage scenario to ensure stable door structure and safe use

The outdoor special aluminum alloy folding door meets the standards for wind pressure resistance and weather resistance, and can be used with confidence. Adopting reinforced and thickened aluminum profiles, the door leaf is equipped with multiple reinforcing ribs inside, and the wind pressure resistance level can reach 12 or above, which can withstand strong winds and typhoon impacts; The surface is sprayed with fluorocarbon, and the coating is resistant to ultraviolet rays, acid and alkali, and aging. It is not easy to fade and paint off after long-term exposure to the sun and rain; Equipped with waterproof sealing strips and drainage system, it can effectively block rainwater infiltration and adapt to complex outdoor environments

Common causes and self solving methods:

  1. Track dust accumulation and debris: Clean the track according to the above cleaning methods, and the jamming can be relieved; 
  2. Splicing or lack of oil: Use a dry cloth to wipe the dust in the gaps of the hinges, and apply a small amount of lubricating oil (such as sewing machine oil, silicone oil); 
  3. Door leaf deviation: Check the fit between the door leaf and the track, and calibrate the position of the door leaf by adjusting the hinge screw; 
  4. Pulley wear: If the pulley is severely worn and causes jamming, it is recommended to contact after-sales service to replace the pulley;

If the above methods are ineffective, you can contact after-sales for on-site maintenance

Under normal circumstances, there will be no water accumulation or rust, and extreme humid weather can be treated accordingly. The track is equipped with drainage holes, which can timely discharge rainwater and moisture, avoiding residual water accumulation; The track is made of 304 stainless steel material, which is not easy to rust.

Solution:

  1. Regularly check the drainage holes to ensure that there are no debris blockages and smooth drainage; 
  2. After humid weather, wipe the track with a dry cloth to remove residual moisture; 
  3. If there is a small amount of rust on the track, it can be removed by wiping with stainless steel cleaning paste, and then applying a small amount of lubricating oil to prevent rust
