When evaluating the installation quality of steel doors and windows, there are several key aspects you should check. These steps will help ensure that the product is not only aesthetically pleasing but also functional and durable.
1) **Inspect the Surface**: The window frame should appear clean, smooth, and free from scratches or dents. Any visible damage or deformation could indicate poor craftsmanship or improper handling during installation.
2) **Check the Hardware**: All hardware components, such as hinges, handles, and locks, must be present, properly positioned, and securely fastened. They should operate smoothly and perform their intended functions without any issues.
3) **Examine the Sealing Strip**: The rubber or foam seal that sits between the glass and the frame should be flat and evenly pressed against both surfaces. Avoid any signs of curling, warping, or gaps that might compromise the seal.
4) **Assess the Seal Quality**: When the window is partially closed, there should be no noticeable gap between the sash and the frame. The sealing surface should remain compressed to maintain an airtight and weatherproof barrier.
5) **Evaluate the Glass Installation**: The glass should be perfectly flat and firmly secured in place. Single-pane glass should not come into direct contact with the frame. For double-glazed units, both inner and outer surfaces should be clean, and the space between the panes should be free of dust, moisture, and any lifted spacers.
6) **Check the Bead (Gasket)**: The bead that attaches to the glass should be tightly pressed against it. There should be minimal or no gap between the bead and the frame’s joints, ideally less than 1 mm. This ensures a secure and tight fit.
7) **Inspect the Splicing Material**: If the window has joined sections, the splicing material should be firmly connected to the frame and sealed with appropriate caulk. Fasteners should be spaced no more than 600 mm apart, and any reinforcing steel should be securely fixed in place.
8) **Test the Operating Components**: Whether the window swings, slides, or rotates, it should close properly and remain tight when shut. Smooth operation is a sign of good installation and quality hardware.
9) **Review the Frame-to-Wall Connection**: The window frame should be level and plumb. The fixing points should be spaced no more than 600 mm apart, and the frame must be firmly attached to the wall. Any gaps should be filled with flexible material and sealed to prevent leaks or cracks.
10) **Verify the Drainage Holes**: The drainage holes should be correctly positioned and unobstructed. They play a crucial role in preventing water buildup and potential damage to the structure.
By following these checks, you can ensure that your steel doors and windows are installed correctly, providing both security and comfort.
