If you want to customize your door even further, you can choose a custom hinge that is best for the door weight and application.
　　Special applications and door types require different hinges. These may be called full mortise, half mortise, full surface, half surface and many other specialty door hinge manufacturer.
　　For example, there are Full Mortise style Bearing Hinges that are exclusively manufactured for high frequency and/or heavy wood or metal doors. Typical applications would find this hinge type in schools, hospitals or public buildings with high traffic.
　　When thinking about custom hinges, you should consider the following:
　　How will the door be used? Will it need to be a fully revolving door or a 180-degree door, for example?
　　How much will it cost to design a special hinge for thickness and size?
　　What size of hinge do you need? If you have heavy-duty, large doors that are load-bearing or have additional equipment that hangs on the door, then you may need a different hinge with a custom thickness.
　　How big and thick is the door?
　　How will you install the hinges? There are four main ways to install hinges including full mortise, half mortise, full surface, or half surface.
　　What style and finish do you prefer?
　　What material is needed for your industrial application? If you need rust-resistant hinges, then you’ll pick stainless steel. Brass, iron, and bronze are also available.
　　Will you need to remove the door or is it fixed?
　　Manufacturing a Commercial Hinge
　　Hinge manufacturing refers to the production process. Both hinges and latches are typically made by the same manufacturer, and they begin the process the same way.
　　To start off, the chosen metal material for the hinge is melted. Once it’s at the right temperature, the manufacturer puts it through several machining processes.
　　After the hinge is created, it’s put through secondary processes to perfect the thickness, size, and shape. These processes include painting, coating, polishing, plating, rust-proofing, smoothing, or galvanization. These are determined based on the application for the door hinge.
　　The manufacturer must consider several things when choosing what product mix to manufacture. These include budget, required production volume, design complexity, and required production speed.
　　Custom Hinge Design
　　When designing a hinge, manufacturers begin with the main components which are typically the leaves, knuckles, and hinge pin.
　　The leaves are plates that fold outward, and they are held together by a knuckle or hollow joint. The knuckle is joined to the hinge by a pin.
　　When installed, the leaves are attached to the separate surfaces that will be held together. Screw holes are drilled into the leaf so that they can be fastened to the door and frame.
　　Standard Fabrication
　　The parts of a door hinge are quite simple to fabricate. These include:
　　Leaf
　　This is also called the wing of the hinge, and it’s the flat piece of the hardware that’s screwed into the frame and door.
　　Pin
　　This long pin slides into the knuckle holding the two leaves together. If you pull the pin out, you can remove the door from the frame. Some doors need removable hinges so that they can easily be lifted and removed.
　　Knuckle
　　The middle part of the hinge is called the knuckle, which is a cylindrical case that allows the leaves to rotate causing the door to move.
　　Sleeves
　　These are the cylindrical pieces that create the knuckle and hold the pin together.
　　Special Application Hinges
　　There are a variety of hinges depending on the application and industry. Hinges may require galvanized steel or other material depending on the temperature and chemical exposure around the door.
　　These have a wide range of uses for standard use, high traffic and extra heavy doors.
　　Example: A welded hinge installation is best when you need to suspend a heavy door. These are capable of holding doors of extreme weights. Bank vaults and blast doors typically use these types of hinges.
　　Unique Hinges
　　For certain industries, warehouses and other businesses in heavy-duty applications need their own unique types of concealed and durable application hinges. A few unique hinge examples include:
　　Wrapping Up: What Type of Hinge is Right for Your Door?
　　There are all kinds of hinges out there for commercial applications. Though butt hinges are the most common and can be used for many door types, specialty hinges can offer concealment or specialty hinges can offer solutions for uncommon applications.
　　So, whether you need an interior or exterior hinge, you must first look at the door weight, any chemical resistances and use application that meets or exceeds the specification required. The right hinge will be able to handle the load and resist corrosion due to exposure to elements, which typically means a non-corrosive material. That’s why it’s best to work with a specification consultant to get your specs right.
　　However, even the strongest hinge cannot help a door that is not sufficient for your commercial building. You need the right door and hinge to withstand the test of time. Good luck and always consult with a professional first before starting your project.
