APTT is your reliable partner in the field of comprehensive aluminum solutions. We specialize in the manufacturing and rapid supply of all types of aluminum profiles from Europe, Turkey, and China to Ukraine.

Our production and distribution capabilities cover the full spectrum of products — from classic standard items (angles, tubes, channels) to complex custom systemic profiles manufactured according to the customer’s individual engineering drawings.

Based on cross-sectional geometry and complexity, aluminum profiles are divided into two main categories:

• Standard Profiles (General Purpose): Basic geometric shapes with simple cross-sections, including solid bars and flat strips, as well as hollow tubes, angles, channels, and T-bars.
• Custom Profiles (Special/Complex Shapes): Products featuring a unique, often intricate cross-sectional configuration engineered specifically to meet precise technical and structural requirements.

Categories of Aluminum Profiles by Practical Application:

• Architectural and Construction: Specialized profile systems designed for assembling window and door units (including energy-efficient solutions equipped with a thermal break).
• Interior and Furniture: Architectural profiles utilized for constructing retail display cases, exhibition modules, commercial shelving, and furniture frameworks.
• Finishing and Trims: Cladding and edge elements engineered for decorative surface styling and physical surface protection.
• Complex Structural Mechanics: Specialized components designed for manufacturing roller shutter systems, window blinds, louvers, and other protective mechanisms.
• Transportation: High-precision rail transit systems, tracks, and linear guideways.

Aluminum Profiles by Cross-Sectional Shape

This classification is based on geometric attributes, regardless of the profile’s field of application:

• Solid Profiles (Monolithic): Formats featuring no enclosed internal cavities (solid bars, flat strips, structural angles, channels, T-bars).
• Hollow Profiles: Formats containing one or more enclosed internal cavities (square, round, and rectangular tubes, as well as complex multi-cavity window systems).
• Open Profiles: Formats featuring a U-shaped, C-shaped, or other types of non-enclosed cross-sectional geometry.

Demanded Aluminum Profiles by Type and Application

Standard General-Purpose Aluminum Profiles

• Aluminum Angle (L-Profile): Ranging from 10x10x1 mm (decorative accents) up to 50x50x5 mm and thicker (load-bearing frameworks). The most high-demand sizes are 20×20 mm and 40×40 mm.
• Square/Rectangular Aluminum Tube: Popular cross-sections include 20×20 mm, 40×20 mm, 40×40 mm, and 60×40 mm with a wall thickness of 1.5–2 mm.
• Aluminum U-Channel (U-Profile): Frequently utilized dimensions are 10x10x10 mm, 15x15x15 mm, and 20x20x20 mm, primarily applied for edging, trim, and structural guideways.
• Flat Bar (Busbar / Flat Strip): High-demand widths range from 20 mm to 50 mm with thicknesses of 2–4 mm.

Commercial & Residential Construction Profiles (Window, Door, and Facade Systems)

• “Cold” Profile Systems: Non-insulated profiles typically featuring a frame depth (mating depth) of 40–45 mm.
• “Warm” Profile Systems: Thermally insulated profiles featuring an integrated thermal break (polyamide strut), increasing the frame depth to 60 mm, 70 mm, or 75 mm to accommodate multi-chamber insulated glass units (IGUs).
• Curtain Wall Mullions and Transoms: Profile depths vary from 50 mm to 150 mm (and deeper) depending on architectural wind loads and structural building heights.

Specialized Lighting Aluminum Profiles (LED Profiles)

• Surface-Mounted / Recessed Profiles: Widths range from 16 mm to 25 mm with heights from 7 mm to 150 mm.
• Corner Aluminum Profiles: Most frequently sized at 16×16 mm or 19×19 mm.
• Trunking Aluminum Profiles (Wide): Widths from 35 mm to 50 mm, specifically engineered to assemble high-output continuous linear architectural lighting.

T-Slot Aluminum Extrusions (Structural System Profiles)

Engineered with modular T-slots for welding-free machinery and frame assembly:

• 20-Series Aluminum Extrusions: 20×20 mm cross-section (lightweight framing, desktop CNC machines, and 3D printers).
• 30-Series Aluminum Extrusions: 30×30 mm cross-section (machine framing, workbenches, and safety enclosures).
• 40-Series Aluminum Extrusions: 40×40 mm and 40×80 mm cross-sections (heavy-duty industrial machinery beds, heavy structures, and conveyors).

Retail Display and Exhibition Infrastructure Systems

• “25 Square” System: A 25×25 mm square aluminum extrusion designed with dedicated grooves/slots to secure glass sheets or chipboard panels.
• Octagonal Upright Posts: Profiles with an octagonal cross-section and a diameter of approximately 40 mm, widely used as structural pillars for modular exhibition stands.
