Overview: 30 Series Aluminum Extrusion Profile
The 30 series aluminum extrusion profile (30 mm x 30 mm nominal cross-section) is a mid-range T-slot framing system widely used in industrial workstations, safety guarding, material handling carts, and light automation frames. It balances structural rigidity with weight efficiency, making it a preferred choice for applications where 20 series is too light and 40 series is over-specified. As a 30 Series Aluminum Extrusion Profile manufacturer, Shanghai Huishuo Aluminum Industry Technology Co., Ltd. offers multiple variants to match load, stiffness, and accessory compatibility requirements.
Key Specifications and Variants
30 series profiles are defined by a 30 mm outer dimension and an 8 mm T-slot (or 6 mm square slot in some versions). Wall thickness, slot geometry, and internal reinforcement determine load capacity. Below is a comparison of common 30 series profiles available from this 30 Series Aluminum Extrusion Profile supplier in China.

Application Fit and Selection Logic
Choose the profile variant based on load, span, and accessory compatibility:
- Light-duty (HS-8-3030L, 1.8 mm wall): For display stands, laboratory ceiling grids, or non-structural enclosures. Lowest weight and cost.
- Standard duty (HS-8-3030A, 2.0 mm; HS-8-3030, 2.1 mm): Suitable for ergonomic workstations, mobile carts, and perimeter guarding. Accepts standard 8 mm T-nuts and fasteners.
- Heavy-duty (HS-8-3030F, HS-8-3030N2, 2.2 mm): For load-bearing frames, machine bases, and safety enclosures requiring higher stiffness. Use when deflection limits are critical.
- Rectangular profiles (HS-8-3060, HS-8-3090): For longer unsupported spans or where bending moment is higher. The 30 mm width maintains slot compatibility while the 60/90 mm height increases section modulus.
- Square slot (HS-6-3030G, 6.3 mm slot): For systems using M6 hardware or where panel mounting with square nuts is preferred. Not interchangeable with 8 mm T-slot accessories.
Material and Surface Treatment
Standard alloy is 6063-T5 or 6061-T6, with T5 being more common for extrusion. Surface finish options include:
- Silver anodized: Standard, corrosion-resistant, good for indoor use.
- Black anodized: Aesthetic choice for visible frames; available on select models (e.g., HS-8-3030).
- Custom finishes: Powder coating, electrophoresis, or brushing can be specified for special environments.
Specify the required surface treatment in the RFQ. For outdoor or wash-down environments, confirm corrosion resistance with the supplier.
Integration with Accessories and Automation
30 series profiles accept standard T-slot nuts, bolts, brackets, and panel-mounting strips. For automation integration, consider:
- Linear guides and actuators: Can be mounted directly into the T-slot using custom brackets.
- Panel mounting: Polycarbonate or aluminum composite panels slide into slot with rubber seals.
- Connectors: Use Aluminium Profile Connectors for rigid joints; Aluminium Profile Fasteners for quick assembly.
For custom machining (drilling, tapping, milling), the supplier offers CNC Aluminum Processing with tolerance down to 0.01 mm.
Quality Assurance and Acceptance Testing
Request the following evidence from the supplier:
- Material certification: Mill test report for alloy 6063-T5 or specified grade.
- Dimensional inspection report: Slot width, outer dimensions, straightness (typically ≤0.5 mm/m).
- Surface finish quality: Anodizing thickness (≥10 µm for standard), color consistency.
- Mechanical testing: Tensile strength, yield strength, hardness (e.g., 8-12 HW for T5).
Acceptance criteria should be defined in the purchase contract. For large orders, consider third-party inspection at the factory.
Buyer RFQ Checklist
Include these items in your RFQ:
- Profile model and quantity (total length in meters).
- Alloy and temper (e.g., 6063-T5).
- Surface finish (silver anodized, black anodized, custom).
- Cut-to-length dimensions and tolerance (±0.5 mm typical).
- Machining requirements (drilling, tapping, milling) with detailed drawings.
- Accessories needed (connectors, fasteners, end caps, seals).
- Packaging (individual wrapping, bundle, or crate).
- Delivery lead time and incoterms (FOB Shanghai, CIF, etc.).
- Required certifications (material cert, dimensional report).
- Acceptance test plan and sampling rate.
Supplier Evaluation Criteria
When evaluating a 30 Series Aluminum Extrusion Profile manufacturer, consider:
- Production capacity: Number of extrusion lines (e.g., 13 lines from 600T to 5000T) and daily output.
- Quality system: ISO 9001 certification (see Certificate page).
- Machining capability: CNC centers with large travel (up to 6.5 m) and tolerance control.
- Surface treatment lines: Anodizing, powder coating, electrophoresis.
- Experience: Years in business and reference projects.
FAQs
What is the difference between 30 series and 40 series aluminum extrusion?
30 series has a 30 mm cross-section and is lighter, suitable for workstations and guarding. 40 series (40 mm) offers higher load capacity for heavy automation frames. Choose 30 series when weight and cost are priorities and loads are moderate.
Can 30 series profiles be used outdoors?
Yes, with appropriate surface treatment. Anodized profiles offer good corrosion resistance for indoor use. For outdoor exposure, specify powder coating or electrophoresis. Confirm with the supplier for environmental conditions.
What accessories are compatible with 30 series T-slot profiles?
Standard 8 mm T-slot nuts, bolts, brackets, hinges, and panel-mounting strips. For square slot versions (6 mm), use M6 hardware. The supplier offers a full range of
Aluminium Profile Accessories.
What is the typical lead time for 30 series profiles from China?
Lead time depends on quantity and customization. Standard stock profiles can ship within 7-15 days. Custom extrusions with new mold development may take 20-30 days. Always confirm with the supplier.
How do I specify the correct wall thickness for my application?
Calculate the maximum bending moment and allowable deflection. For light loads (carts, displays), 1.8-2.0 mm is sufficient. For load-bearing frames or machine guards, use 2.2 mm or reinforced variants. Provide load data to the supplier for recommendation.
