H Frame Steel Scaffolding By Lakshmi Steel & Tubes

We are adept at making available Cold Rolled Precision Tubes for automobile, tools making, bicycle manufacturing and umbrella manufacturing; Hot Rolled Structural Tubes for telecom towers, industrial sheds, bridges and cranes manufacturing; Scaffolding & Electrical Conduit Tubes for general and construction applications; Idler Tubes for conveyor belts manufacturing; Galvanized Steel Tubes for irrigation and drinking water supply and Special Size Tubes for mechanical and general engineering purposes. Steel Tubes offered in different grades, chemical composition, mechanical properties, and dimensional tolerances are suitable to be used in following applications: Bicycle & allied purposes Automotive application Mechanical & general engineering purposes Furniture tubes Propeller shaft tubes The Indian and international standards that are applied for several steel tubes are BS:1717, BS:6323, DIN:2393, DIN:2394, JIS G 3445, ASTM:A-513, JIS G 3466, ASTMA 500 GR A, and BS:4360, IS:2039/1991, IS:3074/2005, IS:3061/2006, IS:7138, IS:4923/1997 and IS:1161/1998. In the making of tubes, following steps are followed: Leveling & slitting Coil & welding Roll & gauge forming Post annealing Water cooling Sizing Flying cutting Straightening End facing Weighing & measuring Marking & coating In the meanwhile, the tubes in process are inspected and subjected to ultrasonic inspection of uncoiled strip edge, ultrasonic inspection, rotary ultrasonic inspection, hydro static inspection, visual and dimensional inspection.
