Frequently Asked Questions About Alloy Gravity Hinge from Bolton Industries
The hinges are manufactured from high-strength aluminum alloy or zinc alloy, depending on the grade. Aluminum alloys are preferred for lightweight and corrosion resistance, while zinc alloys offer cost-effective durability for standard applications.

Sourcing Alloy Gravity Hinge from Bolton Industries - India Import Guide

Before ordering, verify the material composition (aluminum or zinc alloy) and load capacity to ensure the hinges meet your door’s weight and usage requirements. Request samples or technical drawings to confirm compatibility with your door design and fire safety standards. Check whether the hinges are supplied with necessary hardware, such as screws and mounting plates.

Logistics details to confirm include bulk packaging options, container loading capacity, and the supplier’s lead time for large orders. Discuss Incoterms such as FOB or CFR to clarify shipping costs and responsibilities. Payment terms should be negotiated in advance, with options for advance payment or letters of credit for first-time buyers.

Quality checks should include verifying the finish durability and corrosion resistance, especially for outdoor or high-humidity applications. Request test reports for load capacity and fire rating compliance if the hinges are intended for fire-rated doors. Ensure all documentation, including Certificates of Origin and compliance certificates, is provided for customs clearance.
