Final products of the company in black condition are straightened by a 10-Roll Horizontal and a 6-Roll Vertical Straightening Machines in tandem and are stacked for further processing of drilling and punching with the help of fixtures at various platforms of radial drill machines and punching power presses to achieve zero difference holes meant for Railway Electrification, transmission and communication towers to ensure proper group fitting of any product on to it as per RDSO / customer specifications.
Highly experienced staff has been engaged for handling the sophisticated jobs of punching and drilling. Supervisory staff for looking into the quality also helps in to maintain the desired level of drilling schedules provided in different drawings.
Fabrication
Fabrication Process
Most of the steel sections produced by Jain’s are used for welding purposes making either masts, towers, fitting items, cross arms, two to seven track cantilivers i.e. portals, special structural steel etc. etc., hence welding is done through Arc Welding and Mig Welding in accordance with the BIS Code. Branded Anti Spatter Spray are used to get the better performance during hot dip galvanization on all welded materials.
Hot Dip Galvanizing
Hot-dip galvanizing is the process of coating iron or steel with a zinc layer by passing the steel through a molten bath of zinc at a temperature of around 860⁰F (460⁰C). When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc oxide, which further reacts with carbon dioxide to form zinc carbonate, a dull grey, fairly strong material that resists corrosion in many circumstances, protecting the steel from the corrosive elements. Galvanized steel is widely used in applications where rust resistance is needed, and can be identified by the crystallization pattern on the surface. The steps in the galvanizing process are as follows :
- The steel is cleaned in a degreasing solution
- After being cleaned, the steel is pickled by being lowered into a vat of diluted hot sulfuric acid
- The steel is then fluxed in an aqueous solution (typically zinc-ammonium chloride)
- After the flux, the steel is galvanized through immersion in a vat of molten zinc Afterward, the steel is inspected for consistency and a complete coating
