Precautions for installing plastic steel doors and windows

1. Control of flatness and verticality of doors and windows

Use a laser marking instrument to measure the horizontal and vertical heights of doors and windows. The vertical height of doors and windows should not be short, and the vertical plane of doors and windows should be controlled by a 2/3 lift ruler. If the doors and windows are turned outwards, the door and window fans will automatically and slowly close after being turned on. The doors and windows will fall inward, and the door and window fans will slowly and automatically open.

2. Control the deviation of the appearance of doors and windows

Attention should be paid to controlling the deflection of the appearance of doors and windows, and both sides of the doors and windows can be fixed on both sides of the doors and windows. Bottom edge of doors and windows. Pull a piece of fishing line to measure the distance across the bottom margin line.

3. Right-angle control of corner balconies or bay windows. If the front and side angles of the balcony are not 90 degrees, the width of the window sill will be inconsistent. At this point, you'll want to use a large right-angled ruler.

4. Glass installation

When installing glass, two special glass blocks can be placed under the glass, and the bead installation should be short and long. Special attention should be paid to the installation of door and window fan glass to prevent the door and window fans from falling off the chassis. The correct installation method is to place the L-shaped glass block on the bottom and diagonal sides of the sash fan hinge, and not on the side of the actuator. Hang the glass on one side, then place the edge of the bottom and lift the door and sash, adding wedge spacers at opposite corners of the bottom hinges until both the door and sash are level and the beads are reversed.

5. Door and window debugging After the doors and windows are installed, the doors and windows should be debugged to see if there are any quality problems.
