Makers of mechanical door locks are improving selections and building brands to counter rising costs and other challenges.
China suppliers of mechanical door locks are enhancing product performance and aesthetics to make them stand out in the market. Climbing outlay and intense competition are prompting companies to move up the value chain to obtain better margins and avoid engaging in price wars.

Under this effort, many enterprises are adopting stainless steel for lock bodies and some components in place of zinc or aluminum alloy. Designs fabricated from the first material last 20 to 30 years, unlike zinc and aluminum alloy versions that usually do not surpass 20 and 25 years, respectively. Stainless steel products can be priced 15 to 50 percent higher, enabling makers to generate 10 to 15 percent more profit.
Some makers are increasing the number of latches and cylinders in their designs to boost security. Such is the case for Zhongshan City Yonggu Locks Co. Ltd’s model A1078AC rim lock, which has three of the former and two of the second.
For greater visual appeal, manufacturers are adopting a range of surface treatments. Simple and elaborate constructions are being released to meet the requirements of various exterior and interior styles.
Zhongshan Century Huihuang Lock Product Mfg Co. Ltd, for instance, is offering the model QH051085 lever lock with an antique finish. The product is designed mainly for the Middle East and Southeast Asia.
To ensure models are constructed according to specifications, suppliers are investing in CNC lathes, plasma cutting machines and other automated equipment. Facilities for testing hardness, resistance to forced entry and corrosion, service life and other key performance parameters are also being procured.
For further differentiation, many enterprises are building awareness of their brands abroad. Foshan City LCJ Electric Locks Fty is promoting the LCJ trademark, while Zhongshan City Yonggu is marketing products under the Leju label.
To counter growing competition from electronic entry systems, several mechanical lock suppliers are expanding selections for interior doors, window and cabinets. Market penetration of the former has increased with the price difference between the two segments having gone down, thanks to technological advancements and the rising number of manufacturers.

China offers a range of mechanical locks for interior and exterior doors. The selection includes keyed knobs and levers, deadbolts and locksets.
Models with security ratings of A and B account for the bulk of output.
Designs in the first group are capable of withstanding drilling, prying, pulling and punching for 15 minutes before giving way. Illegal entry via sawing can be resisted for 5 minutes.
Locks with B-level protection can hold out against sawing for 10 minutes. These are designed to hinder other types of attack for 30 minutes.
Most models are meant to be mounted on 35 to 60mm-thick doors. They have single or double cylinders, and 11 to 70mm backsets.
Low-end mechanical door locks are generally made of steel or zinc alloy. These can withstand 100,000 locking and unlocking cycles, and 24hr salt-spray testing.
In midrange versions, stainless steel or aluminum alloy is used for the body, while the components are fabricated from a type of zinc, aluminum or steel. The products are capable of 150,000 to 200,000 cycles, and their finishes can resist 36hr salt-spray procedures.
Upscale designs often have copper alloy parts. These are able to withstand 36 to 72hr tests.
