EI Profile 45 x 90 Technical Specification

A comprehensive technical deep-dive into the mechanical, dimensional, and alloy specifications of our flagship structural aluminum profile.

Mechanical Structural Analysis

The EI Profile 45 x 90 is the workhorse of modular framing systems. Engineered with structural optimizing cross-members, it provides an optimal balance between bending stiffness, torsional resistance, and material mass. Typically featuring an 8mm or 10mm T-slot width, it supports heavy M8/M10 fastener systems, ensuring high pre-load holding force with absolute anti-loosening characteristics.

Structural Strength Calculations & Constants

To compute frame deflection under static loads, use the classic deflection equation:

f = (F * L³) / (48 * E * I) [For a simply supported center-load configuration]

Where:

  • F: Applied Load (Newtons)
  • L: Span length of the profile (mm)
  • E: Modulus of Elasticity (70,000 N/mm² for 6063-T5)
  • I: Moment of Inertia (values listed below for X and Y axes)

China Factory 4.0: Supply Chain & Efficiency

How Chengdu E&I leverages China's industrial infrastructure to guarantee lead time and consistent quality.

Operating out of Chengdu, a major industrial hub of China, our facility features complete integration with regional raw primary aluminum smelters. This geological advantage stabilizes our raw material inputs and allows us to buffer against global commodities pricing shifts.

Supply Chain Strengths
  • Zero-delay Tooling Design: Custom profile extrusion dies can be modeled, heat-treated, and cut using high-speed CNC EDM wire machines in less than 7 working days.
  • Fully-automated Extrusion Systems: Multi-ton extrusion presses operate with real-time temperature telemetry at the nozzle, minimizing micro-cracking and variation in alloy hardness.
  • Integrated Post-processing: Secondary operations including tapping, countersinking, angle-cutting, and complex milling are handled on 5-axis CNC machining centers without relocating profiles.

Our quality management workflow follows standard ISO 9001:2015 frameworks. Every production batch undergoes coordinate measuring machine (CMM) testing to confirm that the T-slot geometry stays strictly within the nominal tolerances required for automated t-nuts and sliding structural fasteners.

Furthermore, Chengdu E&I implements a transparent supply chain trace system: every delivery bundle is labeled with batch codes linking back to the raw billet chemistry logs, providing full mechanical validation documentation for critical structural applications.

Global Enterprise Procurement & Compliance

Aligning domestic high-capacity output with international engineering standards and smooth cross-border customs delivery.

International Compliance

Our profiles are manufactured to conform to ASTM B221 (standard specification for aluminum-alloy extruded shapes) and EN 755-9 tolerance standards, allowing designers to swap domestic designs seamlessly into overseas production lines.

Eco & Safety Mandates

All surface finishes, particularly anodized and electro-coated colors, are certified to be REACH and RoHS compliant, ensuring they contain no restricted heavy metals or volatile organic compounds.

Customs & Logistics

With years of export experience to European, North American, and APAC regions, we supply complete HS Code (7604.21.00) classifications, commercial invoices, and origin declarations for fast customs clearance.

Frequently Asked Questions (FAQ)

Addressing structural engineering queries and global sourcing inquiries regarding 45x90 T-slot aluminum extrusions.

What is the difference between 6063-T5 and 6061-T6 for 45x90 profiles?

6063-T5 aluminum is the standard choice for general industrial structures, workbenches, and machine guards. It offers excellent surface finish traits and easy extrudability. 6061-T6 has higher tensile and yield strength, making it better suited for highly stressed load-bearing frames, aerospace jigs, and heavy marine components, though it tends to have a slightly rougher surface profile.

Are E&I aluminum profiles compatible with accessories from other brands?

Yes, our T-slot designs follow standard European configurations (8mm and 10mm slots). Our EI Profile 45 x 90 aligns perfectly with industry-standard T-nuts, angle brackets, slot covers, and gusset plates commonly used worldwide, allowing drop-in compatibility for existing frame modifications.

What surface treatment option provides the best corrosion resistance?

Anodizing (either clear or black) is the standard method, providing a hard aluminum oxide layer that is highly resistant to wear and salt spray. For aggressive environments like chemical laboratories or marine settings, we recommend a hard-anodized treatment (>20 microns) or powder coating for added protection.

Can you provide custom cut-to-length and pre-drilled services?

Yes. We cut profiles to exact specified lengths (within a tolerance of +/- 0.5mm) and offer tapping, counterboring, and custom layout milling. This lets you assemble frames directly upon arrival at your job site without further machining.
