80 Series Aluminum Extrusion Profile Manufacturers

80 Series Aluminum Extrusion Profile – Heavy-Duty Structural Framing for Industrial Applications

The 80 series aluminum extrusion profile is the backbone of heavy industrial framing. With an 80 mm cross-section, these profiles deliver the rigidity, load capacity, and torsional resistance required for machinery bases, multi-level work platforms, conveyor supports, large-span gantries, and automation cells. When your application demands multi-ton static loads or dynamic forces, the 80 series is the correct starting point. As a professional 80 Series Aluminum Extrusion Profile manufacturer, Shanghai Huishuo Aluminum Industry Technology Co., Ltd. offers a range of profiles with different slot geometries, wall thicknesses, and surface finishes to match your exact structural and integration needs.

Key Specifications and Configuration Options

The 80 series family includes several variants, each optimized for a specific load class, assembly method, or accessory compatibility. The table below compares the most common profiles available from this supplier.

Slot Geometry and Fastener Compatibility

The slot design determines which connectors, T-nuts, and bolts you can use. The 80 series offers three slot types:

• 8 mm T-slot – Industry standard for medium-heavy loads. Compatible with M8 fasteners and a wide range of standard accessories from this Aluminium Profile Accessories line.
• 10 mm T-slot – Larger slot width for higher strength fasteners (M10) and increased clamping force. Use when the joint must resist higher moments.
• U-slot (deep slot) – Allows panel mounting, sliding elements, and concealed connections. The deep channel provides more grip for specialty brackets.
• Square-slot – Designed for heavy-duty fixed structures where standard T-nuts are not required. Often used with custom brackets or welding.

Select the slot type based on your accessory ecosystem. If you already use M8 T-nuts and connectors, the 8 mm T-slot profiles minimize inventory complexity. For new designs requiring higher joint strength, the 10 mm slot is the better choice.

Load Capacity and Wall Thickness Trade-Offs

Wall thickness directly influences bending stiffness, weight, and cost. The 80 series profiles range from lightweight (reduced wall) to extra-thick (reinforced). Here is the selection logic:

• Standard wall – Suitable for most machine frames, workstations, and light conveyor supports. Provides a good balance of strength and material cost.
• Thick / thickened wall – Use for columns, heavy press frames, and multi-level platforms where deflection must be minimized. The added aluminum mass increases rigidity by 20–40% compared to standard wall.
• Extra-thick wall (W series) – For extreme loads, such as large gantry beams or vibration-sensitive equipment bases. The extra material also improves thread holding for bolted joints.
• Lightweight (reduced wall) – When weight is a constraint and loads are moderate. Ideal for manually adjusted fixtures or portable structures.

Request a load-deflection calculation from the supplier for your specific span and load. A reliable 80 Series Aluminum Extrusion Profile supplier should provide engineering support for structural analysis.

Surface Treatment and Corrosion Resistance

Standard finish is mill finish or silver anodized. For enhanced corrosion resistance in wet or chemical environments, specify anodizing, powder coating, or electrophoretic coating. The factory operates multiple surface treatment lines, including anodizing and vertical spray coating, as shown on the Factory Tour page. Anodized profiles offer a hard, wear-resistant surface with consistent color. Powder coating provides a thicker protective layer and a wider color range. For outdoor or wash-down applications, request a salt spray test report.

CNC Machining and Custom Fabrication

Most 80 series profiles can be supplied cut to length, drilled, tapped, and milled to your drawing. The supplier’s CNC Aluminum Processing capability includes 26 machining centers with effective machining diameter up to 6.5 m and tolerance precision of 0.01 mm. This allows for precision hole patterns, counterbores, and slotting directly on the profile, reducing assembly time and ensuring repeatability. Include a detailed 2D or 3D drawing with your RFQ to avoid misinterpretation.

Integration with Accessories and Connectors

The 80 series is designed to work with a full ecosystem of Aluminium Profile Connectors, Fasteners, Finishing Parts, and Assembly Parts. When ordering, confirm that the slot size matches the intended connector series. For example, 8 mm T-slot profiles require 8 mm T-nuts and compatible brackets. The supplier also offers Aluminum Profile Frame design and assembly services, which can simplify procurement if you need turnkey structures.

Buyer RFQ Checklist

Use the following checklist to ensure your RFQ covers all critical parameters:

• Profile model and cross-section (e.g., HS-8-8080, 80×80 mm)
• Slot type and width (8 mm T-slot, 10 mm T-slot, U-slot, square-slot)
• Wall thickness or load class (standard, thick, extra-thick, lightweight)
• Alloy and temper (typically 6063-T5 or 6061-T6; specify if required)
• Surface finish (mill, anodized, powder coated, color RAL code)
• Length per piece and total quantity (standard lengths up to 6 m; custom lengths available)
• Machining requirements: drilling, tapping, milling, counterboring – provide drawing with tolerances
• Packaging: individual wrapping, wooden crates, or bulk bundling
• Certification: material test report, dimensional inspection report, surface quality standard
• Delivery lead time and incoterm (FOB Shanghai, CIF, etc.)
• Engineering support: load-deflection calculation, assembly drawing review
