MS Rectangular Pipes

Applications of MS Pipes:

MS (Mild Steel) Pipes are among the most widely used steel products due to their strength, durability, and cost-effectiveness. They serve in structural, mechanical, industrial, and general fabrication purposes. Here’s a detailed list of their major applications:

Structural and Construction Uses
Building columns and scaffolding
Roof structures & sheds like warehouses & cold storages
Support frames for industrial and commercial buildings
Fencing poles and handrails
Signage and gate frames
Industrial and Engineering Applications
Machinery frames and bases
Conveyor systems and equipment supports
Shafts, rollers, and spacers
Hydraulic and pneumatic cylinder tubes (after machining)
Tool, jig, and fixture making
Water and Plumbing Systems
Water supply and drainage pipelines
Firefighting pipe networks
Borewell casing (light duty)
Irrigation and sprinkler lines
Transmission towers and poles
Temporary construction platforms
Automotive and Transport Industry
Frames, axles, and roll cages for vehicles
Truck and trailer chassis components
Exhaust pipes and guard rails
Fabrication and General Purpose
Furnitures (chairs, tables, racks, stands)
Gym and playground equipment
Lighting poles, flag poles, and stands
Agricultural Applications
Greenhouse structures
Borewell casings and irrigation setups
Equipment frames and trolleys
