Frequently Asked Questions
- What is the difference between weld-on and bolt-on hinges?
- Weld-on hinges are welded directly to the gate frame and post, providing a permanent and strong connection. Bolt-on hinges are fixed with bolts and can be removed or adjusted after installation. Weld-on hinges are preferred for steel gates; bolt-on hinges are more common for timber posts.
- What load capacity do I need?
- As a general guide: use 2 hinges per gate leaf. Each hinge pair should have a load capacity of at least 1.5× the gate weight. For a 200 kg gate, use hinges rated at 300 kg per pair or higher.
- Can you supply hinges with stainless steel pins?
- Yes. Stainless steel pins are available as an option for coastal and high-humidity environments. Contact us for pricing.
- What is the MOQ for weld-on hinges?
- MOQ is 300 pairs for standard models. Mixed sizes can be combined to reach MOQ.
