Frequently Asked Questions (FAQ)
-
Q: Are the free samples available for all customers?
A: Yes, we offer free samples for qualified business inquiries. You only need to cover the shipping cost. We will send up to 2 pieces for your evaluation. -
Q: Can I use this bracket for curved glass?
A: This 4-way arm spider bracket is designed for flat glass panels. For curved glass, we recommend using adjustable spider brackets or custom-made solutions. Please consult our technical team. -
Q: What is the lead time for bulk orders?
A: Standard lead time for 100–500 pieces is 15–20 days after order confirmation. For larger quantities, please allow 25–30 days. We can expedite for urgent projects. -
Q: Does this bracket come with screws and bolts?
A: Yes, we include stainless steel bolts, washers, and nuts with each bracket. The default size is M8x30mm, but other sizes are available on request. -
Q: How do I install the spider bracket on a steel structure?
A: The bracket has a central base plate with four holes. Simply fix it to the substructure using appropriate bolts. The glass panels are then clamped between the arms using neoprene gaskets and metal plates (included in the kit). A detailed installation manual is provided. -
Q: Is the satin finish prone to rust?
A: No, SS316 is highly corrosion-resistant. The satin finish does not affect the material's anti-rust properties. However, if the surface is scratched, the passive layer may be temporarily compromised, but it will self-passivate in clean environments. -
