The mechanical components known as latches are those that let pieces move relative to one another while still being momentarily linked. They are set off to split the two members apart by disengaging the connection that was previously keeping them together. The sheer number of different kinds of latches is impossible to quantify, so be sure to consider your design well. Roll up door lock latches may have a wide range of design aspects, each of which might make them more suitable for a certain kind of use. In addition, they are offered in a wide range of materials, coatings, thicknesses, and other features to meet your specific requirements.

Material

Most latches are constructed chiefly of metal, including carbon and stainless steel, alloy steels, aluminum alloys, and copper alloys. Some latches may also be built entirely of plastic. Metal is the most common material for roll up door lock latch because of its long lifespan and incredible strength. Finishing and coating are two examples of secondary operations that may be used to enhance the outward qualities of metal latches.

Metal latches are often covered with plastics and rubber trim, which decreases vibration and acts as a shock absorber for the metal. On the other hand, some locks are constructed of plastic. Plastics become exceedingly brittle when left exposed to the elements for an extended period of time. Because of this, their usage as latches is limited to the inside of buildings.

Finishing and Coating

Finishing and coating are examples of secondary procedures that may be used to enhance the overall surface quality of latches and other types of products. Painting, polishing, and powder coating are included in this category. The processes of polishing and buffing produce a surface that is both smooth and glossy once they are completed. Painting and powder coating are two procedures that may be used to prevent corrosion on a component by adding a layer of a polymer substance to the surface of the element.

Strength

The strength of a latch may range from light to medium to heavy-duty, which determines the thickness of the sheet metal or metal plates used to construct the backplate, battles, and rotors. It should be no surprise that the same principle applies to cams and bolts; the application determines how thick they should be.

Mounting

When it comes to the process of installing latches, there is a large selection of mounting choices from which to pick, such as surface-mounted, mortised, or flush-mounted locks. When it comes to a flush-mount latch, the door and the latch are mounted on the same surface level. One example of a flush-mount latch is a paddle latch, which is the most popular.

The mortise latch is a typical kind of door lock comprised of a deadbolt for locking the door and only has a handle and a keyhole that projects from the door’s surface. Last but not least, surface-mounted latches need no drilling for installation since they are placed by simply bolting the latch assembly onto the surface of the door and frame (though some pre-drilling would help).

Latch Handedness

Even though most latches can be controlled with either hand, some come in left-handed and right-handed variations, so they may be used with greater ease. In addition, many types of slide latches, bolt latches, rotary latches, and slam latches enable the mechanism to be switched out so that it may be used with either the left or right hand.

Fortuitously, not all of the designs provide this functionality, and none of those choices is a viable option. This allows you to choose which hand the latch is meant to be used on by observing the placement of the hinges.
