Production process Concrete piles centrifugal
Step 1: Raw Materials & Design Check: Prepare raw material inputs with good control
– The sand must be in accordance with the pile making module, clean and kept moist
– 1×2 stones are laid out according to standards and are also washed to increase the concrete grade.
– Create steel cages through welding at the factory
In parallel with the material preparation stage, it is necessary to clarify the pile and aggregate designs used to move to the loading stage
Step 2: Loading materials: Install the steel core into the pile mold and proceed to pour concrete with approved mix designs from customers (consultants, investors, construction contractors...). Fill the copha and carefully check the glass level to avoid leaking concrete water and the centrifugal process is not affected.

Step 3: Steel tensioning: Is the step of pre-stressing reinforced concrete piles according to design stresses to have bending resistance moments when put into use. Steel tensile results are saved in the laboratory.
Step 4: Centrifugal rotation: This is a very important step to compact concrete and there are usually 4 levels of rotation for the pile to achieve the designed quality. 
Step 5: Steaming the piles: This step puts the piles into the steam oven at a temperature range of 100oC -/+ 20 to decide to remove the mold early, hot steam will accelerate the hydration process of concrete in a high temperature environment. Normally steaming piles takes about 8 hours. Or depending on the technology of each factory.
Step 6: Remove the mold and check the product: This may be the last step if not going through the high pressure furnace depending on the progress or decisions related to storage at the factory. In this step, we will check and classify piles of the right quality or need other attention.

Step 7: Steaming through high pressure furnace: This is the way at factories that have orders that need to be supplied quickly or want to increase the concrete grade, and right after taking the piles out of the high pressure furnace, we can take the piles out. finished product.
Step 8: Steaming through high pressure furnace: This is the stage of checking the quantity, quality, type of goods and transporting them to the construction site.
