Description

This 28mm Aluminum Alloy Lean Tube Inner 90° Connector is designed for internal corner connections in modular assembly systems. Crafted from lightweight yet durable aluminum alloy, it enables quick construction of rigid 90° angles within lean manufacturing setups such as workbenches, flow racks, and material handling carts. Its inner-type design ensures seamless integration with standard 28mm tubes while maintaining structural integrity under load.

  1. ​​Precision Angle​​: 90° internal bend for compact corner joints in confined spaces.
  2. ​​High-Strength Material​​: Aluminum alloy construction offers corrosion resistance and a 30% weight reduction versus steel equivalents.
  3. ​​Tool-Free Assembly​​: Compatible with standard M6 hex keys for rapid installation/disassembly.
  4. ​​Universal Compatibility​​: Fits all 28mm lean tubes (0.8–1.2mm thickness) without adapters.
  5. ​​Reusable Design​​: Enables reconfiguration of layouts for dynamic production environments.
  6. ​​Smooth Finish​​: Anodized surface minimizes friction during tube insertion and resists scratches.

FAQ

We are a dedicated aluminum profile manufacturer and industrial supplier with our own heavy-duty production base. By managing every stage from extrusion to high-precision anodizing, we guarantee stable structural tolerances, highly competitive factory-direct bulk pricing, and reliable shipping timelines for large-scale enterprise supply chains.

Standard Profiles & Accessories: We support global engineering distributors and system integrators with optimized B2B bulk wholesale MOQ thresholds to ensure efficient international container freight utilization.

Custom & Contract Projects: We prioritize high-volume standardized industrial production. For custom profile extrusions requiring dedicated mold development, the minimum order quantity ranges from 500kg to 1,000kg. We focus strictly on enterprise-level supply and do not accept low-volume retail or DIY hobbyist orders.

For seamless global logistics and tax declaration, our primary exported component series utilize the following standardized classifications:

Aluminum Profiles & Extrusions: HS Code 7604299000

Heavy-Duty Anchor Connectors & Fasteners: HS Code 7616999000

Lean Pipe Structural Foot Supports & Caps: HS Code 3926909090

*(All internal and external commercial shipping documentation is prepared with periods removed from the code for strict customs clearance speed optimization).*

Yes, all our structural profiles and high-strength internal connectors are precision-engineered to meet Universal Metric Standards. Our product ranges are fully compatible and interchangeable with international heavy-duty structural grids, including standard European modular specifications and German MayTec dimensions, allowing system integrators to directly swap components without structural modification.

Absolutely. We specialize in producing high-strength, flush-mount hidden assembly systems. Our Heavy-Duty Anchor Connectors provide rigid internal joints designed to withstand high vibrational stresses in automated heavy machinery cages, material flow racks, and cleanroom workstations, available for high-volume wholesale export along with full structural hardware kits.
