Packing Strips
Steel Strappings are manufactured from low and
medium carbon strapping quality cold rolled steel strips, produced in-house with
utmost control. The strips are then deburred, austempered, painted and waxed in
continuous line with automatic controls, incorporating the latest
technology.Proper selection of grade of steel is made to ensure ideal
combination of physical properties
Steel strappings are produced with
very close tolerances in dimension and physical properties, thereby ensuring a
consistent and uniform quality. The straps conform to Indian and International
Standards viz. IS:5872-1990 and ASTM-D3953. Steel Strappings are available both
for Light Duty and Heavy Duty applications to allow a wise choice to the
customer. Standard properties of straps are as follows:

Special Features
Edges
Edges of the strip
are roller beveled by formed rolls, which removes the burrs and also provides
better contact with seals during sealing.
Surface
Painting of strip
surface is carried out on-line, by dipping in paint tank, wiping to maintain a
constant coating thickness and finally in Infrared ovens. Painting ensures
improved corrosion resistance with 48 Hrs. resistance to neutral salt spray as
per IS-9844-1981.
Waxing of strip after painting improves transmission of
tension during packing, especially around corners of the package, and ensures
slippage load below 6.5 Kgs.
Zinc painting is done with Zinc enriched
paint for corrosion resistance under very severe conditions, as also to provide
cathodic protection when packing galvanized items. Zinc painted strips provide
resistance against salt spray corrosion for 96 Hrs.
Colling
Coils are supplied
either in Ribbon wound single coils, Oscillated Wound Coils and Jumbo Coils.
Ribbon wound coils are single coils with individual layers wound directly over
the previous layer. Oscillated Wound and Jumbo coils are wound on a core with
each layer spaced at a particular pitch over the specified spool
width.
The coils are normally supplied with following parameters.
However, specific requirement of customers may also be supplied on
enquiry.
