It's important to know whether plastic steel doors and windows are reinforced with steel profiles. Everyone is familiar with the advantages of plastic steel windows, such as excellent thermal insulation, dust resistance, fire retardancy, and resistance to deformation and corrosion. High-quality plastic steel windows offer superior airtightness, watertightness, and energy efficiency—up to two to five times better than traditional options. Their aesthetic appeal makes living spaces more comfortable and quieter, which is why they have become so popular in modern homes. The embedded steel lining plays a crucial role in the structural integrity of plastic steel windows. The plastic frame of the sash is combined with the steel profile, enhancing the window’s strength and durability. After anti-corrosion and rust-proof treatment, the steel lining should be at least 1.2 mm thick to ensure long-term performance and stability. Hebei Fengming Company specializes in door and window seals, giving them extensive knowledge of plastic profiles. Below are several practical methods that consumers can use to identify whether steel profiles are included in plastic steel windows. First, you can check the weight of the window. If it feels unusually heavy, it may indicate that steel reinforcement has been added. This is a simple but effective way to assess the quality of the product. Second, examine the window frame and sash closely for any visible nails or rivets. Steel profiles are typically fixed using automatic nails or rivets, so if you see small caps on the outer surface of the frame or sash, this could be a sign that steel lining is present. Third, you can use a magnet to test for the presence of metal. If the magnet sticks to the window frame, it likely contains a steel profile, confirming its structural reinforcement. By using these methods, buyers can make more informed decisions when purchasing plastic steel doors and windows. A well-constructed window not only enhances the appearance of your home but also improves comfort and energy efficiency. With the right knowledge, you can enjoy a peaceful and stylish living environment for years to come.
