45 Series Aluminum Extrusion Profile – Heavy-Duty Framing for Industrial Environments
The 45 series aluminum extrusion profile is engineered for demanding workshop environments where structural rigidity and load-bearing capacity are critical. With a 45 mm slot spacing and reinforced wall thickness, this profile series supports heavy machine bases, multi-level platforms, robot workstations, and high-stress enclosures. As a 45 Series Aluminum Extrusion Profile manufacturer, Shanghai Huishuo Aluminum Industry Technology Co., Ltd. offers a range of standard and custom profiles with T-slots for flexible bolting and accessory integration. This resource helps procurement managers and plant engineers evaluate specifications, select the right profile variant, and prepare a complete RFQ.

Select the profile variant based on the required moment of inertia and allowable deflection. For cantilevered or high-vibration applications, choose extra-thick walls (W series). For cost-sensitive, low-load guards, lightweight L variants reduce material cost.
Material and Surface Treatment
All 45 series profiles are extruded from 6063-T5 or 6060-T6 aluminum alloy, offering a good balance of strength, corrosion resistance, and machinability. Standard surface finish is silver anodized (AA10–AA15). Optional treatments include black anodizing, powder coating (RAL colors), electrophoretic coating, and fluorocarbon painting. The factory operates 6 surface treatment lines, including anodizing and powder coating, ensuring consistent quality. For harsh environments (e.g., chemical plants, outdoor installations), specify enhanced corrosion protection in the RFQ.
Customization and Fabrication Services
The supplier offers advanced fabrication beyond standard cut-to-length. Services include:
- CNC precision machining – drilling, tapping, milling, and slotting with tolerance down to 0.01 mm (26 CNC centers, effective machining diameter up to 6.5 m).
- Custom mold making – for non-standard cross-sections or special T-slot geometries.
- Deep-hole tapping and complex milling for ready-to-bolt components.
- Assembly – frame design and assembly support for turnkey structures.
When ordering custom profiles, provide a 2D/3D drawing with critical dimensions, tolerances, and surface finish requirements. The factory can develop extrusion dies for unique shapes; lead time for mold making depends on complexity.
Integration with Accessories and Other Series
The 45 series is compatible with standard Aluminium Profile Accessories including T-nuts, corner brackets, hinges, and panel mounts. For lighter-duty applications, consider the 40 Series Aluminum Extrusion Profile; for heavier loads, the 50 Series or 60 Series may be more appropriate. The 45 series fills the gap between medium-duty 40 series and heavy-duty 50 series, offering higher stiffness than 40 without the weight penalty of 50.
Quality Assurance and Testing
The factory maintains a quality control department with image measuring instruments, tensile testing machines, and coordinate measuring machines. Certificates include Quality Management System Certification and utility model patents. For critical applications, request material test reports (chemical composition, mechanical properties) and dimensional inspection reports. Acceptance criteria should be defined in the RFQ, including straightness tolerance (typically ≤0.5 mm/m), twist, and surface finish.
Buyer RFQ Checklist
Use the following checklist to ensure complete specifications when requesting a quote for 45 series profiles:
- Profile model – e.g., HS-10-4545W, HS-10-4590L.
- Cross-section dimensions and wall thickness.
- Alloy and temper – e.g., 6063-T5, 6060-T6.
- Length per piece – standard 6 m or custom cut lengths.
- Quantity – total meters or number of pieces.
- Surface finish – anodized (color, thickness), powder coating (RAL code), or other.
- Machining requirements – drilling, tapping, milling, countersinking (provide drawing).
- Tolerances – straightness, twist, cut length (±0.5 mm typical).
- Packaging – individual wrapping, bundles, or crates for export.
- Delivery terms – Incoterm, port, lead time.
- Certification – mill test reports, quality certificates.
- Sample – request a pre-production sample for approval.
Total Cost of Ownership Considerations
When evaluating suppliers, consider not only unit price but also:
- Material quality – consistent alloy composition reduces rework.
- Machining accuracy – tight tolerances simplify assembly.
- Surface treatment durability – affects lifespan in corrosive environments.
- Lead time reliability – delays impact project schedules.
- After-sales support – technical assistance for installation and troubleshooting.

Frequently Asked Questions
What is the difference between 45 series and 40 series aluminum extrusion?
The 45 series has a 45 mm slot spacing and thicker walls, providing higher load capacity and stiffness compared to the 40 series (40 mm spacing). It is suited for heavier machine frames and multi-level structures where 40 series may deflect excessively.
Can I get custom lengths and machining on 45 series profiles?
Yes. The supplier offers cut-to-length, drilling, tapping, milling, and other CNC services. Provide a detailed drawing with tolerances to ensure accurate fabrication.
What surface treatments are available for 45 series profiles?
Standard is silver anodizing. Options include black anodizing, powder coating (any RAL color), electrophoretic coating, and fluorocarbon painting. Specify the required treatment and any corrosion resistance standards.
What is the typical lead time for 45 series profiles?
Lead time depends on quantity, customization, and current production load. Standard profiles are often stocked; custom orders typically take 2–4 weeks after mold approval. Confirm with the supplier.
How do I select the right wall thickness for my application?
Calculate the expected load and allowable deflection. For heavy static loads or cantilevered beams, choose extra-thick (W) variants. For light guards or partitions, lightweight (L) variants are cost-effective. Consult the supplier’s engineering team for beam deflection calculations.
Does the supplier provide assembly or frame design services?
Yes. The company offers aluminum frame design and assembly as part of its one-stop service. They can provide drafting and breakdown drawings for complex structures.
