No garage door security lock can be better than the individual parts that go to making it up. For the majority of the people, they will purchase a lock kit. Either because they have been misled by the name within the quality section, or it looked like it was what they were looking for. They end up finding out they have received nothing more than an object with thin, bendable metal that would bend under the slightest pressure. They have a cheap zinc handle that would simply snap, and they receive a soft steel bolt which would rust solid after a few months within the mechanism. This would not be due to a poorly made component that you were supplied with, rather this is simply how the system will operate when poor and unreliable components are installed within it. Heavyduty, or simply, the wording; this is more than simply a term used to make you think there is something tough about what you are purchasing. Heavyduty simply means reliable enough to stop a break in. Heavyduty means that you are able to lock and unlock your garage door whenever you are required to do so. Heavyduty means it will function for years. Here are four advantages of using heavyduty components when installing a garage door lock.
Withstanding Brute-Force Prying and Impact Attacks
The most ideal means by which to attack the garage door would be with the use of raw brute force. This involves an attacker prying the door open with a crowbar set between the frame of the door and the door itself. The relatively small and light-weight mechanism, weak spring bolt, or inexpensive metal lock box would not hold against the applied force from the attacker. Items are referred to as heavy-duty when their structures have been purposefully constructed with strength of composition in mind, making them ideal for both prying, and for withstanding impacts.
To examine one component as a comparison, lets consider the latch bolt. Numerous low quality parts will possess a low-carbon or zinc-alloy bolt capable of shearing at 1500 N and below. The heavy-duty security lock kits will use only forged 304 or 316 stainless steel as the constituents of both the bolt and locking rod. The MeiGu company, as an example, uses marine-grade stainless steel for both the bolt and the locking rod. This construction will give way before it will break under a 20% load and is considerably stronger than the standard bolt, even at full compression. The die-cast swing handle, or cylinder lock case will similarly have 3-4mm of material whereas very cheap ones would only have 1.5mm.
Ensuring Reliable Operation Under Daily Cyclical Stress
This is an extremely crucial feature for any locking mechanism, and more so for any system that is intended to be opened/closed in varying conditions multiple times a day. A commercial or industrial garage door could be opening and closing anywhere between 5-50 times a day, and at each opening/closing operation the force needs to be transmitted through springs, cams, gears, but also screws which under repeated stress are subject to wearing and can over time begin to loosen or slip, potentially getting jammed. Heavy-duty parts are engineered with fatigue life calculations included, in order for them to operate correctly under stress. MeiGu's swing handle & rod control mechanisms are manufactured with hardened steel pins and gears with approximately 40-45 HRC hardness, and MeiGu's swing handles are built with added ribbing for rigidity and a die-cast zinc frame tested to withstand 50,000 cycles with zero failure, which may lead to reduced costs due to downtime for a shop or warehouse, and further advantages can be gained as a mechanism which always opens every time increases ease of operation for the end-user, and would lead to it actually being used instead of the lock eventually bypassing.
Resisting Corrosion and Environmental Degradation
Most types of lock are not suited to garages at all. Any lock mechanisms are subject to the same deterioration in humid and ever fluctuating temperature, which is caused by frequent temperature changes or, additionally, any vehicle emissions and manufacturing process fumes present. A lock that appears sound, could in fact be inherently weak due to, for example, brittle, rusted springs or a rusted locking mechanism that has actually failed, though to all outward appearance remained intact. These types of failings do not occur in heavy duty components as the latter tend to be manufactured out of more resistant materials, or with the latest surface finishing methods, which enhance longevity:
316 grade stainless steel has outstanding pitting and crevice corrosion resistance, which means that it will survive most environmental conditions which would destroy cheaper grades.meiGu utilizes this grade stainless steel for many of their padlocks, stainless steel hinges and stainless steel latches. They also design parts that will benefit from other durable finishing procedures such as their powder coating process and trivalent chromium plating process, both of which rate over 500 hours salt spray resistance per ASTM B117. Additionally, heavy duty parts use stainless steel or phosphor bronze internal springs (as opposed to a Music Wire spring which is poor and will last only months).
Supporting Higher Door Weights and Larger Geometries
Common household garage doors are made from aluminium or light wood. Industrial or bespoke garages on the other hand may have door weights of several hundred kilos,solid hardwood frames,or heavy duty steel:this weight will often be sufficient to overcome the resistance of the locking mechanism through sheer weight and inertia, and weak points will yield, with the heavy duty parts taking into account such stresses, scaled up appropriately with the weight of the door. The mounting plate will often be much wider and larger than that found on domestic kits and the rods used will be correspondingly thick or numerous, so as to make it even more secure. The MeiGu swing handles are designed specifically for distribution or industrial units, so that they will accept the forces exerted by the door weights above, using locking rods of anywhere between 10-16 mm in thickness and the extraordinarily strong, non-rusting, 8mm staple diameter hooks feature their own mounting plates to accept four mounting screws instead of the standard two. This ensures the force of closing is dispersed over the face of the door evenly. MeiGu also make such things as swing handle locks which work on the side hinged garage door, built from a 5mm thick, stainless steel, forged hinge and stainless steel bearings for a long-lasting, smooth operation. Heavy duty parts will be crucial for the adequate grip that your garage door lock will apply to your garage door.
Conclusion
Simply, you cannot upgrade your garage door security instead of changing the weak lock in your garage. You can defend yourself from the direct attack or let the lock remain durable by working correctly through the everyday stress of keeping huge heavy garage doors against the corrosion. Heavy-duty component parts are able to do all of these for you. MeiGu which specializes in CNC manufacturing, die-casting, forged 304/316 stainless steel parts for over 15 years has integrated strong design and keeping the products remain effective for years in their swing handle lock with rod control, IP65 cylinder lock, stainless steel hinge sets and the full integrated system.
