Building materials knowledge: selection of locks and engineering design requirements


When consumers choose locks, they can use the methods of “seeing”, “listening” and “trying”. For example, stainless steel, zinc alloy and iron locks may be similar in appearance and style. Is it a lock, and then distinguish it by hand? In general, stainless steel of the same thickness is much heavier than zinc alloy. Then it depends on whether the logo and logo of the purchased product are complete (including the product's implementation standards, grades, manufacturer's name, address, production date), whether the package is firm, and whether the contents of the manual match the product.


Look at the surface finish of the lock, whether it is fine and smooth, with or without spots. And "listening" is the most difficult, and the insider can hear the anti-theft coefficient and the quality of the lock.
