Cast Iron I-Section Straight Edge

I-section straight edge provides high rigidity. The cutouts on the side surface are provided for weight reduction, which also reduces the sagging effect and is very effective for large measurements. It is used for blue matching the working surfaces of machine tools and straightness alignment of heavy machinery.

Made generally as per IS: 5268.
Made from good quality, close grained, high density alloyed cast iron conforming to Grade FG 220 of IS: 210
Stress relieved and hand scraped surface.

Straight edge with 90°V

In addition to the standard I-section straight edge, we manufacture straight edge having flat surface on one side and a 90°V on the opposite side. This is useful where both v-alignment and the surface straightness need to be measured specially for scraping process in machine tools.

One side flat and one side with 90° V
Made generally as per IS: 5268-1991
Made from good quality closed grained high Density Alloyed Cast Iron Conforming to Grade FG 220 of IS: 210
Stress Relieved, Hand Scraped Surfaces

Light Weight Straight Edge

In certain situations it is not feasible to carry straight edges made out of heavy casting. For this purpose, the lightweight aluminium straight edge can be used. Relatively lighter than the steel or I-section straight edge, this is suitable for jobs where alignment matters but high accuracy is not the primary concern.

Main body is made out of extruded aluminium section.
Both top and bottom working surfaces are reinforced with steel strips.
Very useful for erections, alignments and other purposes where very high accuracy is not required.
