Stainless Tee Round Bar is an alloy steel with smooth surface, high weldability, corrosion resistance, polishability, heat
resistance, corrosion resistance and other characteristics.
1. Exceptional Durability & Long Service Life (Core Advantage)
Built with high-performance stainless steel grades (typically SUS304 or SUS316), the roll bar inherits the material’s inherent resistance to wear, corrosion, and environmental aging, ensuring long-term reliability:
Corrosion & rust resistance: The chromium oxide passive film on the stainless steel surface effectively isolates moisture, rain, road salts (for automotive use), seawater (for marine use), and industrial fumes. Unlike carbon steel roll bars (which require frequent painting to prevent rust), stainless steel versions remain rust-free even in harsh environments (e.g., coastal areas, off-road muddy conditions) for 15-30 years.
Abrasion & impact resistance: The material’s high tensile strength (≥515 MPa for SUS304) and hardness allow it to withstand scratches from rocks, debris, or daily use without deformation or surface damage. It maintains structural integrity even after repeated minor impacts.
Weather & UV resistance: Resists fading, cracking, or brittleness caused by long-term exposure to sunlight, extreme temperatures (-40°C to 300°C), or humidity—suitable for both outdoor parked vehicles and marine equipment.
2. High Structural Strength & Safety Performance
As a safety-focused component (especially in automotive scenarios), the stainless steel roll bar is engineered for load-bearing and impact resistance to protect users or equipment:
Anti-roll & collision protection: In automotive use (e.g., pickup trucks, Jeeps), it acts as a "protective cage" for the vehicle’s cab. When the vehicle rolls over or is hit, its high yield strength (≥205 MPa for SUS304) and rigidity prevent the cab from collapsing, reducing injury risks to occupants.
Load-bearing capacity: Tubular or solid stainless steel construction (common tubular thickness: 1.5-3mm) enables it to bear heavy loads—for example, supporting roof racks, spare tires, or cargo (up to 50-200 kg, depending on specifications) without bending.
Shock absorption: The material’s moderate toughness (elongation ≥40% for SUS304) allows it to absorb partial impact energy during collisions, reducing the transmission of force to the vehicle body or users.
3. Versatile Adaptability to Scenarios
Stainless steel roll bars are designed to meet the needs of different industries, with strong environmental and functional adaptability:
Automotive applications: Used in off-road vehicles, pickup trucks, and racing cars. It can be customized into single-bar, double-bar, or cage structures; some versions are integrated with LED light mounts or spare tire carriers, enhancing practicality.
Marine applications: Installed on boats, yachts, or offshore platforms as handrails, guardrails, or anti-collision bars. Its resistance to seawater corrosion avoids frequent maintenance caused by salt spray.
Industrial applications: Used in warehouses, workshops, or heavy machinery as safety barriers (to prevent equipment collision) or load-bearing supports. It adapts to dusty, humid, or chemical-rich industrial environments.
