How To Installation?


1. Mark the Hinge Positions

Standard placement for residential doors is 5–7 inches from the top and 10–11 inches from the bottom. For heavy-duty iron hinges, we strongly recommend a third hinge placed exactly in the middle to prevent the door from bowing or sagging over time. Trace the outline of the hinge leaf onto the door edge with a sharp pencil.



2. Create the Mortise (The Recess)

Use a sharp wood chisel to tap along your traced lines. The depth of the cut must match the thickness of the hinge leaf so it sits perfectly flush with the wood. Carefully shave out the wood until the recess is flat and even.



3. Drill Pilot Holes

Place the hinge in the mortise and mark the screw holes. Always drill pilot holes using a drill bit slightly smaller than your screws. This step is critical for iron hinges to prevent the wood from splitting under the high tension of the heavy metal.



4. Secure and Test

Screw the hinges onto the door first, then prop the door in the frame using wedges to maintain a 3mm gap at the top. Once secured to the frame, swing the door several times to check for a smooth, frictionless operation.




How To Use?


1. Weight and Load Distribution

Because iron hinges are designed for heavy-duty applications, such as solid wood or security doors, proper weight distribution is essential.

Use Multiple Hinges: Always use at least three hinges for standard doors. For extra-heavy or oversized doors, a fourth hinge may be necessary to prevent the top hinge from pulling away or the door from sagging.

Check Alignment: Ensure all hinge pins are perfectly aligned vertically. If they are slightly off, the iron-on-iron friction will increase significantly, leading to grinding noises and faster wear on the axis.



2. Anti-Corrosion Maintenance

Iron is more susceptible to environmental moisture than stainless steel, so protecting the finish is your top priority.

Keep Dry: Regularly wipe down the hinges with a dry, soft cloth to remove dust and condensation. Dust can trap moisture against the metal, leading to "pitting" or rust spots.

Surface Inspection: Periodically inspect the powder coating or plating. If you see any scratches or chips, apply a small amount of rust-inhibiting touch-up paint immediately to prevent oxidation from spreading.



3. Lubrication for Silent Operation

Iron hinges can develop a squeak if the internal pin becomes dry.

Lubricate Twice a Year: Apply a few drops of silicone spray or light machine oil (like 3-in-1 oil) to the top of each hinge knuckle.

Distribute the Oil: Open and close the door several times to work the lubricant down into the pin and bearings. Always wipe away any excess oil with a paper towel, as leftover grease will attract grit that acts like sandpaper inside the hinge.




Will the finish match my existing hardware?


The product features a high-quality brushed stainless steel finish. This clean, modern look is designed to match other professional-grade 304 stainless steel handles and locks.




Is it rust-proof?


Yes, it is manufactured from 304 stainless steel, which offers excellent resistance to corrosion and oxidation. This makes it suitable for use in humid environments like bathrooms or kitchens.




How much noise does it make?


It is designed for silent operation. The internal ball-bearing mechanism ensures that the door rotates smoothly without the squeaking or grinding sounds common with traditional hinges.




Why Choose Us
