ã€China Aluminum Network】 1.Aluminum alloy doors and windows can't have oil spots, aluminum chips, burrs or other stains on the surface after processing; any glue strips should not be over-stretched when they are embedded. It should be ensured that the rubber strip grows about 10mm longer than the embedded slot; the rubber strip should be surrounded by a circle, and its butt joint should be docked at the upper corner of the frame and should not be cut into several breaks.
The fittings, hardware, and metal liners used in aluminum alloy doors and windows shall be surface-preserved except for stainless steel.
Glass blocks should be hard rubber or plastic. Reclaimed rubber, wood chips or other absorbent materials should not be used.
After the bead is assembled, the gap should be no more than 1mm.
The amount of overlap between the glass and the window is counted from the edge of the window frame and the fan, and the amount of overlap on each side should not be less than 8mm (the double glass must not expose the aluminum spacer), and the glass should be added underneath when assembling the glass.
2. Before installation and installation of aluminum alloy doors and windows, the vertical, horizontal (elevation) and wall thickness must be determined in three directions. When the net port is installed, the reserved gap between the window frame and the hole opening must be 5-8mm. The gap between the left and right is even. When the burrs are installed, the thickness of the connecting piece must not be less than 2mm.
Diagonal deviation of installation window frame ≤ 2.0mm; verticality deviation of front and side frames (including patchwork) ≤ 2.0mm; horizontal deviation of window frame (including patchwork) ≤ 1.5mm; elevation error ≤ 5.0mm .
Fixing method When installing the net port, fix the window frame to the wall directly with the expansion hose. When fixing, the screw must be tightened with a screw knife. It is forbidden to knock it directly with the hammer. When the burr hole is used, the window frame is fixed by the expansion hose through the connecting piece. On the wall. No matter what method is fixed, the fixing point shall not exceed 600mm, and the fixing part entering the structure body shall not be less than 50mm.
After the door frame is installed, there should be no arching, sagging, warping, deformation, so as not to impede the function of the switch; Before installing the glass, the mortar, debris, etc. in the groove should be cleared to make the drainage hole clear; after the window sash is installed, the appearance quality The surface is clean, there is no large area pitting, scratches, bumps, rust and other phenomena; the surface of the sealant is smooth, flat and free of bubbles.
The finished parts are fully assembled and firm, and there should be no mistakes or minor phenomenon; the sealing strips should be uniform and firm after assembly, and the joints at the corners of the box should be tightly bonded and free from the phenomenon of groove removal. There should be no gap breakage.
The panels and quoins are made of natural stone, quartzite, granite, limestone, sandstone or slate. Each panel is composed of a number of individual natural stones that have been dressed by hand and adhered together with a cement back reinforced with a light metal or fibreglass mesh. All panels and quoins are Z-shaped in order to hide the joints from view, therefore, creating an authentic stone wall appearance each time.
Made from natural stone, our panel systems improve in colour and maintain the beauty and characteristics in all climates, therefore the perfect alternative to manufactured stone and traditional methods.
