Locks and hinges imported from China according to European standard
Our hardware suppliers for construction and furniture manufacture zinc-plated steel locks and hinges for passage doors in a wide variety of sizes according to European regulations, which regulate their characteristics based on their use and the weight of the door they are installed on.The European standard EN 1935:2009 concerning hardware for building construction and single-axis hinges classifies hinges and hinges as follows:
- Grade 1. Light duty. Locks and hinges for doors or windows of residences or living spaces with low frequency of use.
- Grade 2. Medium duty. Locks and hinges to be installed on doors with average frequency of use and limited public access.
- Grade 3. Heavy duty. Hinges and locks for buildings’ doors with high frequency of use, such as in public buildings.
- Grade 4. Severe duty. Hinges and locks to be installed on doors subjected to frequent improper and violent use.
Depending on the weight of the door, which mainly depends on its thickness and material of manufacture, locks and hinges must also have specific characteristics.The number of hinges or hinges per door is determined by the height, width, weight, and frequency of use of the door. Generally, for doors up to 203 centimeters high (without door closers), 3 hinges are used. One should be added for each additional 50 centimeters of height. However, the weight and frequency of passage should be considered to determine the optimal quantity of hinges or hinges.As for mortise locks for wooden doors, the most common in the building sector are those with reversible unified latch with a zinc-plated steel front, like the ones we manufacture and import. This type of latch can be used on passage doors and doors with deadlocks. The usual measurements range from 30 to 60 mm of latch distance, with a front height of 120 to 235 mm and rounded edge with 8 mm square spindle.Inquire about the conditions for importing or manufacturing in China your custom locks and hinges starting from a minimum order of 5,000 units (locks) and 10,000 units (hinges).
