- Wrought iron is an iron alloy with a shallow carbon content with fibrous tiered slag inclusions. Wrought Iron bends better than cast iron while maintaining excellent corrosion resistant qualities. Wrought iron is also challenging, malleable, ductile, and easily welded. However, wrought iron’s slag inclusions make obtaining a porosity-free and crack-free weld difficult. Wrought iron welding processes include:
- Hinges, another crucial component, bear the weight of doors and windows, allowing them to open and close smoothly. They are available in different materials, sizes, and styles to accommodate various design requirements and load-bearing capacities. From traditional brass to modern stainless steel, hinges not only serve a functional purpose but also contribute to the aesthetic appeal.

As mentioned above, wrought iron is the stronger, more durable material because the hand-forging process develops a tough, almost wood-like grain in the iron which allows it to withstand significant pressure.

Moreover, the material features definitive cross-sections allowing an easier machining process, which increases flexibility.
Once the old rollers are removed, the new rollers can be installed in their place. This is done by inserting the rollers into the designated slots on the window frame and securing them with the screws or bolts that were removed earlier. Once the new rollers are installed, the window can be placed back into the track and tested to ensure that it opens and closes smoothly.
Adjusting the rollers on sliding doors is a straightforward process that can greatly enhance their functionality. By following the steps outlined above, you can ensure that your sliding door operates smoothly and lasts for many years. Regular maintenance, including cleaning and lubricating, will further ensure optimal performance. With a little time and effort, you can keep your sliding doors in excellent condition and enjoy their benefits throughout your home.
The surface of the wood grain finish should be smooth and flat, and no obvious inclusions. The wood pattern is clear and there is no obvious leakage and crease. However, creases and no wood grain patterns are allowed at the corners and grooves. If the wood grain pattern is ghosted or blurred, the finish is unqualified.

As the movable part of windows and doors, hardware accessories must guarantee the performance and quality to ensure the safety of windows during long-term using time. Windows and doors handle need to conform to ergonomic design, high transmission performance, wear resistance and corrosion resistance; hinges require high hardness, strong toughness and not easy to deform; locks require smooth opening and closing and tightly engaged.
