One, what is the thickness of a heavy sliding door?
The thickness of the frame for heavy sliding doors needs to be determined based on the size of the door and the intended use area.
For example, heavy sliding doors used on balconies can have frame thicknesses ranging from 1.6mm to 2.5mm. Most commonly, 2.0mm frames are used.

For heavy sliding doors used in kitchens and bathrooms, which require thicker materials, thicknesses of 1.0mm, 1.2mm, and 1.4mm are acceptable. Most commonly, 1.4mm is used.
The sliding doors for wardrobes can be thinner, with thicknesses of 0.6mm, 0.8mm, and 1.0mm being acceptable.
Two. Thickness of glass for heavy-duty sliding doors.
The thickness of the glass used for heavy sliding doors should also be determined based on the size of the door and the intended use area. For doors such as terrace doors and entrance doors, thicker glass is recommended to enhance insulation and noise reduction. For wardrobes, kitchen and bathroom doors, thinner glass can be used, which offers a better cost-performance ratio.
Furthermore, the thickness of the glass in heavy-duty sliding doors is also related to the material of the glass itself.
Common flat glass is available in four specifications: 2mm, 3mm, 4mm, and 5mm.
Float glass is available in seven specifications: 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, and 12mm.
The thickness of the fiberglass is available in 6mm, 7mm, and 10mm specifications. The dimensions of the specifications are generally not less than 600mm x 400mm and not more than 2000mm x 1200mm.
Please note that the safety of glass in heavy-duty sliding doors is not directly proportional to its thickness. Therefore, it is important to select the appropriate glass based on actual requirements.
