No doubt the newest technology arrival and availability of modern equipment combination has proved to be effective in the quality of coils production. However, in Panchdeep Metal quality factor is given major importance that is resulting in assuring the quality of AISI/SS 420 / 420J1 / 420J2 Coil production. To bring out the high quality of the product they are using stunning quality of raw materials and are considering various raw materials quality standards. Also, the quality control team is taking full care of the quality of production. Aside from that, the production is done under the strict supervision of a professional team that is guaranteeing in bringing out the good quality of product.
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.
