Heat treatment: The profile undergoes different systems for quenching and aging treatment to obtain the mechanical properties of the profile .

Unlike aluminum, wrought iron is heavy, making it an excellent choice for heightened security measures. The strength of the material makes it incredibly difficult to breach, and its weight adds a level of durability that aluminum simply can’t match. 

One of the most critical functions of window and door fittings is to provide security. High-quality locks, hinges, and handles are essential for safeguarding the home against intruders. Multipoint locking systems, for example, are becoming increasingly popular due to their ability to secure the door at multiple points, making it significantly more challenging for burglars to gain entry. Additionally, reinforced hinges and heavy-duty handles not only provide added security but also enhance the durability of the doors and windows, ensuring they withstand daily wear and tear.

This process applies chemicals and electricity on the surface of extruded aluminum profile to form a relatively thick layer of oxide.
