Frequently Asked Questions
-
Q: What is the maximum glass weight this bracket can support?
A: The bracket is designed for heavy-duty use. Typically, each arm can support up to 500 kg under static load, but the actual capacity depends on glass thickness, panel size, and local wind/snow loads. We recommend consulting our engineering team for a specific calculation. -
Q: Is this bracket compatible with both tempered and laminated glass?
A: Yes, the bracket works with most glass types, including tempered, heat-strengthened, and laminated glass. The 200mm arm length accommodates standard edge clearances. Always ensure proper fitting with the glass manufacturer’s specifications. -
Q: Do you offer custom hole patterns or arm lengths?
A: While the standard product is 200mm with a 14mm hole, we can provide customization for larger series orders. Please contact us with your requirements. -
Q: What is the difference between satin and polished finish?
A: Satin finish has a matte, brushed appearance that reduces glare and hides fingerprints. Polished finish is mirror-like and more reflective. Both are corrosion-resistant; the choice is aesthetic based on the architectural design. -
Q: How is the bracket attached to the building structure?
A: The bracket typically mounts to a steel or aluminum subframe using bolts (not included). The 4-way arm ends have threaded inserts or through holes for connecting glass panel clamps or spider fittings. -
Q: Can you provide samples before bulk order?
A: Yes, we offer sample brackets for evaluation. Please contact our sales team to arrange a sample, with shipping costs to be covered by the buyer. -
Q: What is the typical lead time for this product?
A: For standard quantities (100–500 pieces), lead time is approximately 15–25 working days after order confirmation. Larger orders may require 30–40 days. We can expedite for urgent projects upon request.
