Did you wonder how PARU's solar PV trackers are made?
Today, our manufacturing process will be revealed!
|PARU New Building|
Let's get started!
1. Material Warehousing & Incoming Inspection
PARU performs visual inspections on the incoming steel.
The supplier will perform functional tests prior to product delivery
and provide a certificate to PARU.
PARU will also perform a thorough functional inspection
before further processing.

2. Laser Cutting & Bending
When the materials arrive from the suppliers,
they are laser-cut, bent, and pressed into the desired shapes.
With visual inspections, dimensional measurements are performed by hand
with calibrated tools and compared with original drawing.
3. Manual & Robot welding
PARU has a welding jig set to make sure that pieces are welded
in the correct place and alignment.
The jig set includes two jigs:
for the top and the bottom post.
4. Process Inspection
Another visual inspection and a magnetic particle inspection
will be performed after welding.
PARU's inspection sampling rate is 1%.
Any defects found during the inspection will be sent back.
The welded parts will be sent out for galvanization at third parties.
The galvanization contractor performs 100% inspections on appearance
and on bending/deformation test.
And he or she provides certificates of compliance with the delivered product.

7. Packing & Shipment
The last procedure of the manufacturing is packing.
After packing, the products will be delivered directly to the project sites.
