For B2B buyers working on shower enclosure projects, the success of the installation often depends on decisions made long before the glass arrives on site. Because SVA shower hinges mount directly onto tempered glass, any error in hole placement, panel sizing, or edge finishing can result in breakage, rework, or safety concerns. The checklist below covers the essential points to verify before glass fabrication, along with maintenance advice you can pass on to end users.

Key Checks Before Ordering Tempered Glass:

Confirm Glass Type and Thickness: Tempered safety glass is the only acceptable option. SVA hinges are designed for 8mm to 12mm (5/16" to 1/2") glass. Ordinary glass should never be used, as it cannot handle the clamping force or thermal stress.

Verify Hinge Model and Angle: Establish whether the hinge is 90°, 135°, or 180°, and whether it connects glass-to-wall or glass-to-glass. This directly affects where holes must be drilled and how much edge clearance is required.

Provide Accurate Drilling Data: Supply the exact hole diameter, center-to-center spacing, and distance from the glass edge. Incorrect hole sizing remains one of the leading causes of glass failure during installation.

Check Door Dimensions and Swing Direction: Confirm door width, height, and opening direction, ensuring enough clearance for the door to swing freely without contacting walls or fixtures.

Specify Edge Treatment: Request polished or chamfered edges to minimize stress concentration and reduce the risk of chipping during handling and installation.

Managing the Risks:

• Source glass from a fabricator experienced in shower enclosure work.

• Obtain a drilling template or technical drawing from your hinge supplier before production begins.

• Never attempt to drill tempered glass after tempering, it will shatter.

• Lock in all hardware dimensions before cutting, since post-tempering changes are not possible.

Installation and Maintenance Advice for End Users:

Installation: Only use tempered safety glass. To prevent damage to the hinge finish during installation, do not use power tools when installing these hinges.

Daily Care: Dry the shower door daily with a soft towel or cloth to ensure its original finish. Do not use harsh cleaners or chemicals on the hardware, as many of the components are coated with a clear lacquer that will become damaged beyond repair. Always test your cleaning solution in an inconspicuous area prior to cleaning the entire hardware surface.

Cleaning Method: Wipe surfaces clean using a soft, dampened cloth or sponge, and rinse completely with warm water immediately after applying the cleaning solution. Use only small amounts of a gentle, liquid cleaner. Never use abrasive products, sponges, or wire scrub brushes while cleaning hardware.
