Titanium U Channel

Titanium u-channels, also known as titanium u-sections or titanium structural channels, are U-shaped profiles typically manufactured by extrusion or hot rolling. Combining high rigidity with lightweight properties, they are widely used in applications requiring high corrosion resistance and lightweighting, such as shipbuilding, aerospace supports, chemical equipment frames, and architectural curtain wall structures.

Popular alloy types

Chalco can supply U-shaped channels in a variety of titanium alloy grades, including industrial pure titanium, α-β alloys and special purpose alloys, to meet the structural needs of multiple fields such as marine, aviation, chemical, and construction. The following are several types of titanium alloys we recommend and their typical applications in titanium U-shaped channel products:

• 

  Grade 2 Titanium U Channel titanium u-shaped channels are widely used for their excellent seawater corrosion resistance, good cold-workability, and high ductility. They suit structures like offshore platforms, water treatment frames, and condenser supports, resisting chloride corrosion and extending service life.

• 

  Grade 5 Titanium U Channel titanium is widely used in aerospace for its high strength, fatigue resistance, and light weight. Grade 5 U-shaped channels are ideal for aircraft load-bearing structures, UAV slide rails, and high-speed vehicle frames, offering rigidity, crack resistance, and high-temperature performance.

• 

  Grade 7 Titanium U Channel titanium u-shaped troughs, with palladium content, resist chloride and acidic corrosion. They are ideal for pickling tank supports, chemical tower frames, and pipe racks, offering greater durability than Grade 2 for chemical industry applications.

• 

  Grade 12 Titanium U Channel titanium u-channels offer excellent weldability, heat resistance, and galvanic corrosion protection. They are ideal for heat exchangers, exhaust pipe brackets, and pressure vessel frames, especially in electrochemically sensitive or high-temperature, humid environments.

• 

  Grade 23 Titanium U Channel titanium u-channels, the ELI version of Grade 5, offer higher toughness and biocompatibility. They are ideal for medical device brackets, laboratory instruments, and MRI-compatible structures where both strength and purity are crucial.

Select suggestion:

Different application environments have different requirements for the alloy performance of titanium u-shaped channels. The following are recommended selection suggestions based on the usage scenarios to help you match project needs more efficiently .

• For use in seawater or humid environments, it is recommended to choose Gr2, which is both corrosion-resistant and economical.
• There are high requirements for structural strength and lightness. It is recommended to choose Gr5, which is suitable for aviation or load-bearing occasions.
• For long-term contact with acid, alkali or chemical media, it is recommended to choose Gr7, which has stronger resistance to crevice corrosion.

Solutions and practical cases in different industries

Shipbuilding and offshore engineering

Titanium U-shaped channels are often used in floating platform railings, deck frames and desalination equipment brackets, and remain stable and reliable even under long-term exposure to high salt spray environments.

Case: A domestic offshore wind power platform uses Grade 2 titanium U-shaped channels to replace stainless steel brackets, with no corrosion record in 5 years and reduced maintenance costs by approximately 30%.

Aerospace

Titanium U-shaped grooves are widely used in aircraft cabin guide rails, satellite cabin frames and UAV frames, taking into account high strength, weight reduction and fatigue resistance.

Case: A European aviation parts manufacturer purchased Grade 5 titanium U-channels for use in lightweight seat structures. The materials are 18% lighter than aluminum alloys and have passed fatigue tests exceeding 20,000 cycles.

Chemical equipment

In the support structure of chlor-alkali tanks and pickling equipment, titanium U- shaped grooves can withstand high corrosion, high temperature and intermittent impact conditions, far exceeding traditional stainless steel.

Case: A large-scale desalination plant in Mexico replaced its 316L stainless steel structure with Grade 7 titanium U-channels. After 36 months, there was no sign of corrosion, and annual paint maintenance was completely eliminated, resulting in cumulative savings of over US$120,000 over three years.

Architectural decoration

Titanium U-shaped channels are used for coastal curtain wall keels, sunshade structures, etc. They have good weather resistance and decorative properties, and anodizing treatment can provide a variety of color options.

Case: A sea view hotel in Dubai, UAE uses titanium U-shaped grooves as the brackets for the facade sunshade device, which can resist wind, sand and salt spray erosion for more than 5 years and still maintain a smooth appearance.

Medical devices

Grade 23 ELI titanium U -shaped groove is commonly used in high-standard medical occasions such as MRI equipment frames and sterile room support structures due to its non-magnetic and high cleanliness.

Case: A German medical device manufacturer uses titanium U-shaped channels instead of stainless steel frames for X-ray imaging equipment to avoid magnetic interference and reduce the total weight of the equipment by 15%.
