Storage
Profiles are protected from contact with hard, rough and sharp objects during transport, avoiding high temperatures, sun, rain, oil, corrosive chemicals, dust and other damage during storage. When the profile is stored outdoors, it must be shielded and protected. Non-white profiles should be stored away from light.
Cutting
Cutting speed 60-70m / / sec;
Ensure proper feed rate; blunt serrations or too fast feed rates can cause cutting
Mouth defect
Accurately adjust the saw blade angle to 45 degrees, the maximum angle error is 0.5 degrees;
Strictly according to the given length limit, the length error does not exceed 0.5mm;
The cut profile should be placed with the cut down and the weld completed within 48 hours. In order to avoid excessive storage, the surface of the incision is contaminated, which affects the quality of the welding.
Drilling and milling
The feed rate and cutting speed of the borehole decrease as the depth of the borehole increases;
Double-slot drills should be used for drills with diameters greater than 20 mm, and progressively lighter drills should be used for drills with diameters greater than 40 mm.
Adding lining steel
When the member meets one of the following conditions, the inner cavity must be lined with reinforced steel;

D. Install the components of the hardware accessories.
The fasteners are made of 4mm large-head self-tapping screws or self-tapping screws with washers. The drilled hole diameter should be no more than 3.2mm to ensure the tightness.
The fixing screws at both ends shall not exceed 100 mm from the end of the lining steel, and the number of fasteners used to fix the reinforced steel shall not be less than 3, and the spacing shall not exceed 300 mm.
