Please prepare for the installation based on the confirmation by both parties and the spot situation.
2. Installation and size confirmation of steel structure:
2.1 The bottom of the aluminum track should be 5mm lower than that of the false ceiling. According to the experience data, the distance between the aluminum track bottom and the Z-steel topside is about 250mm. The steel structure should be installed in line with actual spot situation and the installation size is the net size after deducting the height of aluminum track and the length of screw on the track.
2.2 Welding method of steel structure
For the ordinary steel structure, the welding should (see Figure 2) include the following several steps:
First, the single code should be fixed with the expansion bolt into the bottom of slab (as shown in Table 1, L-single code distance) and the precisely measured angle iron should be vertically welded into single code.
Then fix the two sides of angle ironⅡ(the maximum length is 6m) at the bottom of angle iron Ⅰand angle ironⅡwill be welded firmly.
Next, the angle iron Ⅲ should be welded into single code which is also fixed into the bottom of slab according to the diagram. Then fix the angle ironⅠand angle ironⅢ respectively with strong pliers and adjust the position of angle ironⅡproperly.
During the processes of welding and installation, the string and the ruler should be used to guarantee proper adjustment and measurement. The standard steel structure is shown as Figure 2. As for the special steel structure, the welding and installation depend on the actual situation.
The installers should wear safety cap and other safeguard implements. Also, the extinguisher should be equipped at the working area.
3. Please refer to Figure2 and figure3 for the insulation of aluminum track. The sequence of installation is first fix “L”, “T” and “+” types of intersection with corresponding sizes, and then install the straight track.

Detailed Installation Method
Put the square nut to the aluminum track channel and put the screw into the square nut (Note: the screw should be whirled till reach the bottom of the channel), and then turn the hexagonal nut tightly to the top surface of aluminum track. As for the distance of each screw, the operator should refer to the L-screw distance (Table 1).
Next, install the hexagonal nut Ⅲ and the top surface of the aluminum track is about 150-250mm (the same distance for each screw rod).
The distance of about 10mm should be remained between nut Ⅲ and nut Ⅱ, and a needle is used to fix the joint where the aluminum tracks are connected together. The open surface of aluminum track should be vertical to bottom surface for this will ensure that the connection is tight. The two side parts of the track at intersection positions (including “L” type, “T” type and “+”type intersections) beside the square iron board should be hung with screw rods.
