A good way to identify plastic steel doors and windows with or without steel lining

The steel frame embedded within the plastic profile plays a crucial role in the structural integrity of the window. The plastic frame of the sash is combined with the steel lining, which significantly improves the window’s tensile and pressure resistance. After undergoing anti-corrosion and rust-proof treatments, the thickness of the steel lining should be at least 1.2 mm to ensure long-term durability and performance.

Hebei Fengming Company specializes in door and window seals, giving them deep expertise in plastic profiles. Based on their experience, they’ve compiled several practical methods for consumers to identify whether a steel frame is present in plastic steel windows.

First, you can check the weight of the window. If it feels unusually heavy, it’s likely that a steel frame has been added. This is because the steel reinforcement adds significant mass to the structure.

Second, take a close look at the window frame and sash. If you see visible nails or rivet caps on the outer edges, this could indicate that the steel frame is fixed using these fasteners. Since the steel lining must be securely attached to the plastic profile, it’s common to find such marks on the exterior of the window.

Third, you can use a magnet to test for the presence of metal. If the magnet sticks to the window, it’s a strong indication that there is a steel frame inside.

By using these simple techniques, you can make a more informed decision when purchasing plastic steel doors and windows. Choosing the right product ensures not only quality and safety but also long-term comfort and peace of mind in your home. I hope these tips help you find the perfect solution for your living space.
