The use of doors and windows lock is related to our lives, it is about our security. Door and window hardware lock security you know it! Here to see the hardware and the door and window security:
First, we should choose high-profile, quality and good after-sales service of the enterprise products.
Second, the first check the product packaging logo, logo is complete (including the implementation of the product standards, grade, production company name, address, date of production) packaging is solid, the contents of the instructions and products are consistent, beware of exaggerated And the fact does not match the phenomenon.
Third, observe the appearance of the product quality, including the lock, lock body, lock tongue, handle and cover plate parts and the supporting parts are complete, electroplating parts, spray paint surface color is bright, uniform, with or without rust, oxidation Signs and damage.

From a durable point of view, the best material should be stainless steel, especially for surface materials, the more the more light. Its strength, corrosion resistance, color unchanged. However, there are a variety of stainless steel, can be divided into ferrite and austenite. Ferritic stainless steel is magnetic, commonly known as stainless steel iron, a long time, the environment will not rust well, only austenitic stainless steel will not rust, identification method is very simple, you can use a magnet to identify.
Copper is the most widely used one of the lock material, its mechanical properties, corrosion resistance and processing performance are good, and bright color, especially forged copper handle and other decorative locks, the surface formation, density, Trachoma. Both solid and rust-proof, can be used to plated 24K gold or gold and other surface treatment, appears magnificent, noble and generous, to add a lot of color to people's homes.
Zinc alloy material, its strength and anti-rust ability worse, but its advantage is easy to make complex patterns of parts, especially pressure casting. More complex patterns seen in the market of the lock is very likely to do zinc alloy, consumers should carefully identify.
Iron and steel, better strength, lower cost, but easy to rust, the general internal structure for the lock material used, not for external decorative pieces.
Aluminum or aluminum alloy, ordinary aluminum alloy (except for aerospace) soft and light, the material strength than the end, but easy to shape processing.
