Attributes
In the industry, the production of coils is done by making effective use of raw materials. This leads one in bringing out several good features like high tensile strength, good dimensional accuracy, rugged construction, corrosion/heat/thermal resistance, durability, withstanding heavy loads, high flexibility etc.
Testing
In the industry, testing is done with the prime motive of supplying a very good quality of product that can result in better production. The tests conducted are PMI test, hardness test, bend/impact test, eddy current test, flattening/flaring test, macro/micro test, IGC test, chemical/mechanical test,
Packaging
The packaging of the product is done by using a very good packing technique that is guaranteed safety in shipping. The packaging is done in carton boxes, wooden crates/pallets/boxes.
A buyer can now easily buy the product in bulk from a repeatable dealer and enjoy the greater discounts that he gets.
