The Process Flow & Duration Estimation
Raw Material Process
This step includes few kind of process like steel cut by sawing or laser cutting, pipe tubular forming and welding blades or flights on the pipe. Each specific methods and technologies to enhance the efficiency and quality of the raw material to next deep process.
Deep Process
According the raw material process, this step go with deeper process, such as the tread rolling (improve improve the strength of the screw) and heat treatment to achieve increased strength and toughness.
Galvanizing and Moulde
Quality Control and Shipment
Quality Control includes checking the dimensions, thread quality, and the thickness of the galvanizing layer. All of the screws are typically bundled together and may be protected with wrapping to prevent damage during shipping.
SGS Test and Certifications
Test Method: According to the client’s requirement, place the solar panel ground screws on two supports which can span is 1mm, and then apply the compress force on the midspan till totally damaged. Determine the maximum force.
The diameter of support and plunger is 30mm.
Test speed: 12mm/min
Test result: the maximum compress force is 1680kgf.
