Main Applications of Steel Pipes in the Automotive Segment:
Automotive
Structure and chassis
Used in the manufacture of chassis, bodywork and reinforcement parts, providing high strength and impact absorption capacity.

Suspension and Steering System
Essential for coil springs, stabilizer bars, suspension bushings, and steering columns.
Exhaust system
Stainless steel or carbon steel pipes are used in exhaust systems and manifolds, offering resistance to high temperatures and corrosion.
Engine Components and Fluids
Fuel lines, cooling systems (water + additive) and heat exchangers.
Internal Parts and Safety
Seat structures, panels, "cross car beam" (panel crossbeam) and interior door protection.
Armor
304L stainless steel alloys are used for vehicle protection.
Formats and Types:
The tubes can be round, square, rectangular (metal tubing), or oblong, varying between welded (most common) and seamless. The surface can be black, galvanized, or treated for greater resistance.
