About the Product

What Is a U Profile?

A U Profile is a structural material generally made of steel. It takes its name from its U-shaped cross-section. U Profiles deliver high performance in load-bearing and support applications across a range of structures. These profiles are frequently used to support structures and install cladding materials. U Profiles are designed in various lengths and sizes to meet specific requirements.

Applications

Light Steel Buildings

Solar Energy Systems

Warehouses and Hangars

Differences Between Galvanized U Profiles and NPU / UPN Sections

The term "U demir" (steel channel) generally refers to hot-rolled NPU or UPN sections. Hekim Profil does not manufacture these products. Our galvanized U Profile and NPU/UPN sections are not interchangeable:

	NPU / UPN	Galvanized U Profile
Manufacturing	Hot rolling, with tapered inner flange faces	Cold forming from galvanized steel sheet
Thickness	Web approx. 4.5 to 14 mm, flange approx. 7 to 24 mm	1.00 to 4.00 mm
Applications	Beams, columns, machine frames, heavy-duty supports	Light steel construction, partition wall framing, facade and roof substructures
Projects	Industrial buildings, platforms, buildings with heavy structural steel frames	Prefabricated buildings, light steel buildings, interiors

U Profile Types

U Profiles are available in types with different properties for a wide range of applications. Coatings and mechanical properties can be selected to suit the project designs and drawings prepared for these applications. Raw materials and a zinc coating for corrosion protection can also be selected according to the project in which the profile will be used.

Galvanized U Profile

Galvanized U Profiles are frequently chosen for construction and industrial projects for their durability and long service life. Their zinc coating protects against rust, making them reliable even in harsh weather conditions. Available in various sizes and thicknesses, these profiles are an ideal choice for projects requiring ease of installation and strength. The zinc coating class is determined according to customer and project requirements.

U Profile Features

U Profiles offer users a range of beneficial features:

Their high load-bearing capacity offers reliable performance across many projects.
They facilitate manufacturing, shipment and installation, enabling faster and more economical use.
They are particularly suitable for protecting structural systems against earthquakes and natural disasters.
They offer an ergonomic solution by making components easy to add and remove.
They are environmentally friendly because they contain recycled material.

U Profiles are manufactured in the required lengths and sizes on advanced production lines, with hole punching to the dimensions and along the axes specified in the project details, burr-free cutting, inkjet marking on the profiles, and custom packaging for individuals and organizations. Three-dimensional profile drawings loaded into our computer-controlled, fully automatic, high-capacity machines enable holes to be punched at any point on the profiles. Profiles can be manufactured with a maximum length of 16,000 mm, a maximum thickness of 4.00 mm, material grades from S235JR to S355JR, a maximum web dimension of 400 mm and maximum flange dimensions of 100 mm.

Coatings and mechanical properties can be selected to suit the project designs and drawings. Hard or soft materials can be selected according to the applied loads, while corrosion resistance can be specified through the zinc coating thickness or paint applied to hot-rolled steel sheet.

How Are U Profiles Installed?

U Profile installation may vary slightly depending on the type. First, surfaces must be clean to ensure the profiles are positioned correctly. Suitable wall plugs must be used where the products will be installed to secure the screws. A drill, screws, wall plugs and a spirit level should be available during installation.

U Profile Applications

U Profile types are used in many sectors, including construction, automotive, electrical and electronics, metals, structural steelwork, light steel construction and energy. U Profiles serve as load-bearing or secondary members in industrial buildings and building automation systems. They can also be used as load-bearing columns, beams and roof members in non-industrial steel buildings such as warehouses, shelters and hangars.

U Profiles are used as secondary members, including purlins, girts and facade profiles, in industrial buildings with heavy structural steel frames subjected to extreme loads. In non-industrial steel buildings such as light steel buildings, warehouses, hangars and livestock shelters, they are used as load-bearing columns, beams and roof trusses.

These profiles are used under names such as U Profile, U purlin profile, U girt profile, roof profile, facade profile, light steel building profile, structural steelwork profile, profile for buildings with heavy structural steel frames, perforated U Profile, drawn U Profile, custom structural profile, steel building profile, prefabricated building profile, custom U Profile, prefabricated building profile, framing profile, truss profile and steel roofing profile.

U Profile Maintenance and Protection

Protecting and maintaining U Profiles is important for both safety and extending the material's service life. Rust is the greatest threat to steel materials. Various protective coatings can be used to prevent rust. Paint and other protective coatings prevent corrosion by isolating the steel from water and oxygen. Galvanizing involves applying a zinc coating to the steel; the zinc prevents rust by protecting the steel against oxygen and water.

All profiles should be inspected at regular intervals and maintained as necessary. Regular maintenance allows early detection of signs of corrosion so that appropriate action can be taken.
