Our custom extruded square aluminum profiles are precision-manufactured from high-quality 6063-T5 aluminum alloy, offering excellent strength, corrosion resistance, and machinability. The 25x25mm hollow tube features integrated T-slots and internal reinforcing ribs, providing exceptional structural rigidity while remaining lightweight. The profiles are extruded to custom dies, straightened online for precise straightness, and cut to your required lengths. They receive a natural mill finish with passivation treatment for basic corrosion protection, and can be further processed with CNC drilling, tapping, milling, or cutting as needed. As a professional OEM manufacturer, we offer full custom service for unique cross-section designs, dimensions, and surface treatments, making these profiles ideal for custom framing, structural supports, and equipment assemblies.

This custom extruded square aluminum profile is widely used in industrial and commercial applications requiring lightweight, rigid, and modular structural solutions:

• Equipment frames and machine bases
• Workstations and assembly lines
• Conveyor systems and automation equipment
• Industrial enclosures and protective guards
• Retail display and shelving structures
• Agricultural equipment frames
• Solar panel mounting structures
• Custom machinery and equipment assemblies

As a professional custom aluminum extrusion manufacturer, we provide comprehensive OEM/ODM custom service for your square aluminum profile requirements:

• Custom cross-section design (including custom T-slot patterns, wall thicknesses, and internal rib configurations)
• Custom dimensional adjustments (different cross-section sizes, custom cut lengths)
• Secondary CNC machining (drilling, tapping, milling, chamfering, notching)
• Custom surface treatments (anodizing, powder coating, chromate conversion coating)
• Small prototype runs and large-scale mass production with flexible MOQs
• Custom packaging and labeling solutions
• We work with your engineering team to develop custom dies and tooling, ensuring your extruded aluminum profiles meet exact specifications and performance requirements.

• Modular, easy assembly design: Integrated T-slots allow quick, secure connections with standard fasteners, eliminating complex welding or fabrication work and reducing assembly time.
• Lightweight yet rigid structure: 6063-T5 aluminum alloy with internal reinforcing ribs provides high strength-to-weight ratio, preventing bending or deflection under load while remaining easy to handle and install.
• Corrosion-resistant mill finish: Natural passivation treatment offers basic corrosion protection, suitable for indoor and dry outdoor environments without additional coating, reducing maintenance needs.
• High-precision extrusion tolerances: Controlled dimensional accuracy (±0.1mm) and straightness ensure seamless fit between profiles and accessories, eliminating alignment issues in custom framing projects.
• Full custom design flexibility: Our custom service allows you to tailor every aspect of the profile to your application, including cross-section, length, and machining, avoiding the limitations of standard off-the-shelf extrusions.

We implement strict quality control processes throughout the entire production cycle to ensure consistent, high-quality aluminum profiles:

• Raw material inspection (6063-T5 aluminum alloy composition and hardness verification)
• Extrusion die validation and first-article inspection
• In-process dimensional checks (cross-section size, wall thickness, and straightness)
• Surface quality inspection for extrusion defects, scratches, or dents
• Secondary machining quality verification (drilling, tapping, and milling accuracy)
• Final batch inspection and packaging quality checks
• All products are manufactured to ISO 9001 quality standards, ensuring reliable performance for your industrial applications.

• Can you create a custom extrusion profile for my design?

  Yes! As a custom aluminum extrusion manufacturer, we offer full OEM/ODM custom service. We can design and build custom dies based on your drawings or samples to produce profiles tailored to your exact requirements.

• What secondary machining operations can you perform on these profiles?

  We offer CNC drilling, tapping, milling, cutting, chamfering, and notching to prepare the profiles for assembly, including custom hole patterns and fastener locations.

• What surface treatments are available besides the mill finish?

  We offer anodizing (clear, black, or colored), powder coating, chromate conversion coating, and other finishes to meet your aesthetic and corrosion resistance needs.

• What is the lead time for custom extrusion orders?

  Tooling development typically takes 2-3 weeks, with production lead times ranging from 15-30 days depending on order quantity and complexity.

• Do you support small-batch or prototype orders?

  Yes! We offer flexible MOQs, including small prototype runs and large-scale production, to support projects of all sizes.
