FAQ

If there is a malfunction with bathroom hardware products, how do I contact after-sales service for repair?

If a product malfunctions, you can contact after-sales service via the Guandao Hardware official customer service hotline or online service channels (such as the official website and WeChat public account). Provide proof of purchase, a description of the fault, and on-site photos, and the after-sales staff will respond promptly to guide you in troubleshooting simple faults. If the issue cannot be resolved on-site, after-sales will arrange for professional technicians to visit your home for repair or replacement of parts. For specific repair procedures and scope, please consult customer service, which will be carried out in accordance with the product warranty policy.

What are the installation height requirements for bathroom grab bars?

The installation height of bathroom grab bars should be determined based on the specific usage scenario and the users’ needs. The standard installation height is 90–110 cm, which is suitable for most adults; however, if there are elderly individuals or children in the household, the height can be adjusted accordingly—lowering it to 85–95 cm for seniors and adding auxiliary grab bars for children. During installation, ensure that the grab bar is level, fits tightly against the wall or glass surface, and is securely fastened with screws, to prevent improper height from compromising comfort and safety.

What should be done if a glass partition becomes unstable after installation?

First, inspect the fixing hardware of the glass partition—such as connectors and brackets—for looseness, and tighten any loose fastening screws. If shaking persists, check whether the floor and wall surfaces are level; if uneven, adjust the bracket height or use shims to ensure even load distribution across the partition. For large-area glass partitions, consider adding additional support points to enhance stability. During installation, ensure that all hardware components are properly seated to prevent loosening caused by improper installation.

What glass thicknesses are suitable for glass connectors?

Guandao hardware glass connectors are compatible with tempered glass of various thicknesses, typically 6mm, 8mm, 10mm, and 12mm. The specific compatibility depends on the connector model and specifications. When purchasing, it is essential to determine the actual thickness of the glass and select a connector with the corresponding specification to prevent unstable installation or glass damage due to mismatched specifications. For special thickness requirements, customers can contact the manufacturer for custom services.

What is the typical service life of pulleys in sliding door hardware, and how can it be extended?

Under normal operating conditions, the service life of sliding-door pulleys is 3 to 5 years, depending on usage frequency and maintenance. To extend their service life: regularly clean dust and debris from the track and pulleys to reduce friction; apply lubricant to the pulleys and track every 6 to 12 months; avoid frequent overloading or excessive force when opening and closing the door to prevent excessive stress on the pulleys; and promptly inspect and repair any signs of jamming or unusual noises to prevent minor issues from escalating.

How can bathroom hardware products be protected from accelerated aging in humid environments?

Ensure adequate ventilation in the bathroom on a daily basis to promptly remove moisture and reduce ambient humidity; avoid prolonged immersion of metal fixtures in water, and wipe off any surface moisture immediately after use; regularly clean and maintain metal fixtures to remove surface stains and limescale; choose metal fixtures that are suitable for bathroom environments—such as those made from 304 stainless steel—which offer superior corrosion resistance and moisture-proof performance, effectively slowing down aging.

How should rust on bathroom door handles be dealt with after a period of use?

For minor rust, gently wipe the surface with a soft cloth dampened with a small amount of white vinegar or lemon juice, let it sit for 5–10 minutes, then rinse thoroughly with clean water and dry completely with a dry cloth to remove the rust. For more severe rust, use a dedicated metal rust remover according to the instructions; after removing the rust, rinse well with clean water and dry thoroughly. In daily use, avoid prolonged exposure of the handle to standing water, wipe it dry promptly after use, and periodically apply a thin layer of anti-rust oil to extend its service life.

What should you keep in mind when cleaning glass partitions on a daily basis?

When cleaning, avoid using corrosive cleaning agents such as strong acids or strong alkalis to prevent damage to the glass surface and hardware fittings. It is recommended to wipe with a soft cloth dampened with a neutral detergent; after removing water spots and stains, dry thoroughly with a dry cloth to prevent residual water marks. Do not use sharp objects to scrape the glass surface to avoid scratches. Regularly inspect the joints between the glass and the hardware, and clean any dust accumulated in the gaps to prevent buildup from affecting both appearance and structural integrity.

What should be done if the glass becomes loose after the glass connector is installed?

First, disconnect the power supply to the relevant area to prevent glass movement and potential damage; then inspect the connector’s securing screws, tightening any that are loose by turning them clockwise to ensure a tight fit between the connector and the glass. If the screws remain loose after tightening, verify that the glass thickness is compatible with the connector, or replace the connector with one of the appropriate specification. During installation, make sure the shims are properly positioned to enhance the securing effect.

What should be done if the sliding door hardware does not slide smoothly after installation?

First, inspect the track for any foreign objects that may be causing blockage; clean away dust and debris, then try again. If the movement remains sluggish, adjust the height of the pulleys to ensure even load distribution on both sides. At the same time, check whether the track is misaligned; make minor adjustments to the track’s mounting screws to keep it level. For routine maintenance, periodically apply a small amount of lubricant to the pulleys and track to reduce friction and maintain smooth operation.
