Advantages of Stainless Steel Junction Box

There is a good reason why JCL offers a specific service of stainless steel junction boxes. Stainless steel offers numerous advantages when compared to other materials. Following are some of the advantages of stainless junction boxes.


Materials Strudness
Materials Strudness

Stainless steel is a material with very high resilience due to its corrosion resistance and high strength properties. These stainless steel enclosures can resist a great amount of pressure and heat and can offer exceptional resistance against wear and tear.

Material Ductility
Material Ductility

Due design and how they are manufactured, the stainless steel cabinet has to be ductile. This is essential as material needs to be bent, twisted and stamped to get the desired shape. All this with the ability to provide strength to the final product.

Environmental Impact
Environmental Impact

Stainless steel control boxes have the least impact on nature and are the most environmentally friendly products. As stainless steel always provides a long lasting product and at the end of product life, the material can be easily and efficiently recycled. This provides an eco-friendly long lasting solution.

Fabrication of Stainless Steel Junction Box

At JCL we are fully capable of fabricating any design of stainless steel junction box for our customers. Our fully developed sheet metal fabrication shop includes but not limited to

Sheet metal cutting

Sheet metal cutting is done to cut the metal sheet of required thickness to the required length and width for fabrication of the stainless junction box. JCL owns sheet metal cutters of different types and sizes to cut sheets of any thickness and of any dimension.

Sheet metal bending / forming

Sheet metal bending or forming is the main process in fabrication of stainless steel enclosures and stainless steel cabinets. These processes develop the main shape and body of the product and thus are very important to fabricate successful products. JCL has a dedicated team of skilled workers who operate bending and forming machines of all types and sizes.


Sheet metal punching and hardware insertion

To make the body of the stainless junction box able to assemble, attach, and hold different electrical components inside it, several punches and hardware insertion like nuts, and studs are required. Process of sheet metal punching and inserting nuts or studs is relatively simple and is done seamlessly at JCL.

Sheet metal deburring

Processes like bedding, forming, punching, and insertion can leave rough edges and sharp corners. To deliver high end products, the JCL team always performs a deburring process to its stainless steel junction boxes.
