Door Hinge FAQ
What is a heavy duty door hinge?
A heavy duty door hinge is a butt hinge with thicker leaves (usually 3–6 mm), a larger size (4.5–5 in) and ball bearings in the knuckle. It is used on heavy, wide or frequently used doors such as entrance, commercial, steel and fire-rated doors.
How many hinges does a door need?
Use 2 hinges on doors up to 1.5 m high, 3 hinges up to about 2.3 m and 4 hinges up to about 3 m, then add one for every extra 750 mm. Add a hinge on wide or heavy doors and doors with closers.
What size hinge do I need for a door?
Most 35–40 mm interior doors use 3.5 in (89 mm) hinges, standard 44 mm doors use 4 in or 4.5 in (102–114 mm) hinges, and heavy or 50 mm+ doors use 5 in (127 mm) heavy duty hinges.
How much weight can a door hinge hold?
It depends on size, leaf thickness, bearings, number of hinges and fixing. As a guide, three 4 in ball bearing hinges with 2.5–3 mm leaves suit doors up to about 60 kg, and four 5 in heavy duty hinges with 4–6 mm leaves suit doors up to about 120–160 kg. We confirm the load for each model.
Is 304 or 201 stainless steel better for door hinges?
SS304 resists corrosion better because it contains more nickel, so use it for exterior, bathroom, coastal and humid areas. SS201 costs less and is suitable for dry interior doors. HIPAD makes hinges in both grades.
Are ball bearing hinges better than plain hinges?
Yes, for most doors. Ball bearings reduce friction and wear in the knuckle, so the door swings quietly and does not sag as quickly. Use two bearings for interior doors and four for heavy duty and commercial doors.
What hinges are used on aluminum and uPVC doors?
Profile doors use surface-mounted 3D adjustable hinges, two-wing slot hinges or lift-off aluminum hinges that fit the profile, instead of mortised butt hinges. They can be adjusted after hanging and are color-matched to the profile.
What is the MOQ for door hinges?
MOQ starts at 500 pcs for stainless ball bearing hinges, 1,000–2,000 pcs for aluminum and 3D hinges and 5,000 pcs for uPVC butt hinges. Samples take 3–7 days and production 20–25 working days.
Can you make hinges to our drawing with our logo?
Yes. We make hinges to your size, thickness, hole pattern, bearings, material and finish, and add logo stamping and private-label packing, even for small quantities.
