Question 1

What is a weld-on gate hinge?

Accepted Answer

A weld-on gate hinge (also called a weldable hinge or weld hinge) is a type of gate hinge designed to be permanently attached to a steel gate frame or post by welding, rather than using bolts or screws. Weld-on hinges provide a stronger, more permanent connection than bolt-on alternatives, making them the preferred choice for heavy-duty steel gates, farm gates, and commercial security gates. HST Hardware manufactures weld-on hinges in both flag-plate and barrel styles, in sizes from 66×100mm to 200×140mm.

Question 2

What is the difference between weld-on hinges and bolt-on hinges?

Accepted Answer

Weld-on hinges are welded directly to the gate frame and post, creating a permanent, high-strength connection ideal for heavy gates (500kg+) and high-security applications. They cannot be removed without cutting. Bolt-on hinges feature a welded plate on the gate side and a bolt-on plate on the post side, allowing the gate to be removed for maintenance. HST Hardware's H3-83×104 is a popular combination bolt-on/weld-on hinge for this purpose.

Question 3

What load capacity do HST Hardware weld-on hinges support?

Accepted Answer

Load capacity depends on the hinge model and installation method. Our standard bearing weld-on hinges (BH1+BH2, BH7) support gates up to 300–500 kg per pair. Heavy-duty flag hinges (H2-66×100, H2-200×140) are rated for gates up to 800 kg per pair. For gates exceeding 800 kg, we recommend using 3 or 4 hinges per gate leaf, or contact us for a custom heavy-duty solution.

Question 4

What is the minimum order quantity (MOQ) for weld-on hinges?

Accepted Answer

The standard MOQ for weld-on hinges is 300–1,000 pairs depending on the model. Bearing hinges (BH series) have a MOQ of 300 pairs. Heavy-duty flag hinges (H2 series) have a MOQ of 1,000 pairs. For mixed-model orders, we can combine quantities. Contact us to discuss your specific requirements.

Question 5

Can HST Hardware produce custom weld-on hinges?

Accepted Answer

Yes. We accept OEM orders for custom hinge dimensions, plate thickness, pin diameter, bearing type, and surface finish. Custom hinges require a minimum order of 500 pairs and a sample approval process (typically 7–14 days). Please provide technical drawings or reference samples when requesting a custom quotation.
