Metal engineering acceptance

Rules for the acceptance of metal works Metal works include metal doors and windows, anti-theft nets, handrails, etc., which should be checked and accepted in terms of appearance and quality. While pursuing the beauty of the home, it must also ensure home safety.

Metal engineering acceptance specification: 1. Metal ceiling engineering acceptance specification: applicable to all kinds of metal plate (strip plate, square plate, grid) ceiling project. Inspection quantity: general survey of perception, 20% of the total number of random random inspections for allowable deviation items. 2. Code for acceptance of metal wall engineering: applicable to decorative engineering of metal decorative panels (stainless steel, aluminum alloy and profiled steel plates), walls and columns. Inspection quantity: general survey of perception, 20% of the total amount of random random inspection of allowable deviation items. 3. Metal door and window engineering acceptance specification: applicable to various series of aluminum alloy doors and windows, metal sound-proof doors, stainless steel and titanium-plated doors, and metal clad doors. Inspection quantity: check one by one.

Metal engineering acceptance criteria: 1. The variety, specification, opening direction and installation position of aluminum alloy doors and windows should meet the design requirements. Pay attention to the wall thickness of the aluminum profile. The inner cavity of the expansion joint between the plastic steel window lining steel, the window frame and the opening is filled with foam plastic (VP), expanded polystyrene and other wall materials in layers. 2. Note that the aluminum alloy windows, plastic steel windows, the water outlet and the inner cavity of the profile (lower edge) are fixed with screws, and silicone heads are required. 3. Whether the structure of the metal body is straight; if it is the window part, the sealing parts such as rubber strips are required to be complete. 4. Whether the metal window is flexible and unobstructed. 5. Check whether the solder joints of the anti-theft nets, anti-theft doors, etc. have been polished, fixed firmly and not loosened. 6. Is there any leakage of rainwater between the window and the window? 7. When closing the balcony, pay attention to the brickwork of the rain canopy and flower canopy along the window, and waterproof treatment should be done after the interior and exterior are painted with cement. 8.
