SPECIAL PROFILES AND FLAT BARS

D.H. Exports manufactures special Profiles in the form of Flat bars, Ellipse Bars, Half round Bars and various other shapes and sizes.

Flat Bars:- D.H. manufactures variety of sizes in Flat Bars commonly known as Key Steel Flats.

These Flat bars are majorly used for manufacturing Pump/Valves and Machine keys.  However, the Flat bars are not just limited to use in engineering sector, but are also widely used in Decorative hardwares and fittings.

 

D.H. Exports produces Flat bars with sharp corners as well as with round corners to suit individual needs.

Advantages offered by D.H. Exports:-

·         Reduction of wastage during manufacturing of components since the bars are produced in near close tolerance.

·         Reduction of resources in job like saving of labour cost and machine hours and increasing productivity of components.
