China Titanium and Titanium Alloy H-Shaped Profiles Factory - Trusted Suppliers of Gr2, Gr5, Gr7 ASTM B348 Products
Products Detail
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
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.
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.
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
- 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.
- 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.
- 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.
Frequently Asked Questions (FAQ)
What are Titanium H-section profiles?
Titanium H-section profiles are structural H-shaped beams made from titanium or titanium alloys. They feature a unique "double web + flange" design that combines high bending strength with lightweight and weather-resistant advantages.
How do titanium H-beams compare to steel profiles in weight and strength?
Titanium H-beams are 43% lighter than steel profiles of equivalent weight due to titanium's low density (4.51 g/cm³), while offering 30% higher bending strength thanks to their optimized stress distribution.
What are the typical applications for GR2 Pure Titanium H-Beams?
GR2 H-beams are ideal for light load-bearing and basic corrosion-resistant applications. Common uses include load-bearing beams for offshore platform walkways and equipment support structures in food processing facilities.
Why is GR5 titanium alloy selected for wind turbine tower supports?
GR5 alloy H-beams are chosen because they can withstand extreme temperatures (-50°C to 400°C) and heavy fatigue stress from turbine blades. They also reduce structure weight by 40% compared to steel, lowering overall energy consumption.
Can titanium H-section profiles be customized?
Yes, titanium H-beams offer high processing adaptability. They can be customized to specific dimensions, including flange widths of 30-150mm, web heights of 50-200mm, and wall thicknesses of 3-12mm, enabling direct welding and assembly.
