Titanium and Titanium Alloy H-Shaped Profiles

Titanium H-section profiles are H-shaped beams (with an “H” cross-section) made from titanium or titanium alloys. They feature high strength, lightweight properties, and excellent corrosion resistance. The “double web + flange” structural design combines high bending strength with lightweight advantages. Paired with titanium's inherent corrosion resistance, it serves as a core structural component for “load-bearing + weather-resistant” applications in marine and high-end infrastructure sectors. Grades are tailored to meet diverse requirements:

I. Core Characteristics: Dual Advantages of Structure and Material

● Mechanical Properties: High strength, low weight. The H-shaped cross-section distributes stress, offering 30% higher bending strength than steel profiles of equivalent weight. Titanium's density of 4.51 g/cm³ is 43% lighter than steel, significantly reducing overall equipment load.

● Corrosion Resistance: Maintains stability across diverse media. GR2 resists fresh water/mild corrosion, GR5 withstands extreme temperatures/fatigue, GR7 endures acid/salt spray—adapting to harsh environments;

● Processing Adaptability: Supports custom flange widths (30-150mm), web heights (50-200mm), and wall thicknesses (3-12mm). Enables direct welding and assembly, minimizing secondary processing.

II. Grade-Specific Applications

1. GR2 Pure Titanium H-Beams (Light Load-Bearing + Basic Corrosion Resistance)

● Applications: Load-bearing beams for offshore platform walkways, equipment supports in food processing facilities;

● Value: H-beams with flange widths of 30-60mm support pedestrian and equipment loads on walkways, resist seawater/food liquid corrosion, remain rust-free for 5 years, and offer lighter installation than stainless steel profiles.

2. GR5 Titanium Alloy H-Beams (High Load Capacity + Harsh Environment Resistance)

● Application: Internal support structures for wind turbine towers;

● Value: H-section profiles with flange widths of 60-120mm and web thicknesses of 80-180mm withstand stresses transmitted by wind turbine blades. Withstands temperature variations from -50°C to 400°C, offers fatigue life up to 20 years, and reduces weight by 40% compared to steel profiles, lowering energy consumption.

3. GR7 Titanium Alloy H-Beams (Corrosion-Resistant Load-Bearing)

● Applications: Support beams for acid tanks in chemical plants, frameworks for hydrometallurgical equipment;

● Value: H-section profiles with flange thicknesses of 40-80mm support acid tanks weighing 5-20 tons while resisting corrosion from dilute sulfuric acid/organic acids. Eliminates structural collapse risks from steel corrosion, with a service life exceeding 10 years.

III. Key Advantages: Core Reasons for Replacing Traditional Materials

Compared to steel H-beams (prone to rust, heavy weight) and aluminum alloy H-beams (low strength, poor acid resistance), titanium and titanium alloy H-beams achieve “load-bearing without added weight, corrosion resistance without replacement.” They are particularly suited for long-term structural support in outdoor, underwater, and highly corrosive environments.
