The versatility of stainless steel is unmatched as the material can be produced in such a wide variety of different forms. One of these forms is stainless steel strip coil, which is equally versatile and is used for an exceptionally wide array of applications from flexible tubing to filtration devices, from springs to heating elements and from surgical instruments to cutlery. Typical uses of stainless steel slit coil include heat exchangers, heating elements, flexible tubing, filtration devices, cutlery products, springs, and surgical instruments.

Quality Control
We have adopted the Quality Policy that there can be no compromise where the quality of our products is concerned. A strict systematic quality control program ensures that products conform to customer specifications in component, size and physical properties.
Packing
All our products are packed, stored, transported according to the international regulation.
The stainless steel bar rods are packed with woven bags, kraft paper, bundles, wooden cases, etc. Identification labels are tagged according to standard specification or customer's instructions. Special packing is available as per customer's requirement. Plywood cases are available for special protection. Other kinds of packing can be offered if request.
The versatility of stainless steel is unmatched as the material can be produced in such a wide variety of different forms. One of these forms is stainless steel strip coil, which is equally versatile and is used for an exceptionally wide array of applications from flexible tubing to filtration devices, from springs to heating elements and from surgical instruments to cutlery. Typical uses of stainless steel slit coil include heat exchangers, heating elements, flexible tubing, filtration devices, cutlery products, springs, and surgical instruments.

Quality Control
We have adopted the Quality Policy that there can be no compromise where the quality of our products is concerned. A strict systematic quality control program ensures that products conform to customer specifications in component, size and physical properties.
Packing
All our products are packed, stored, transported according to the international regulation.
The stainless steel bar rods are packed with woven bags, kraft paper, bundles, wooden cases, etc. Identification labels are tagged according to standard specification or customer's instructions. Special packing is available as per customer's requirement. Plywood cases are available for special protection. Other kinds of packing can be offered if request.
