Description

This 28mm Lean Tube Multi Connector (Inner Type) is designed for seamless internal connections in modular tube systems. It enables the assembly of lean manufacturing structures like workbenches, racks, and material handling carts by joining multiple tubes internally. Compatible with standard 28mm diameter composite pipes, it ensures robust and concealed linkages without external protrusions.

  1. ​​Internal Connection Design​​: Fits inside tube ends for hidden joints, maintaining structural aesthetics and safety.
  2. ​​Multi-Angle Configuration​​: Supports 90°, T-type, cross-shaped, and adjustable-angle assemblies for versatile layouts.
  3. ​​High-Strength Material​​: Crafted from cold-rolled steel (2.5mm thickness) with anti-rust electroplated or chromed finishes.
  4. ​​Tool-Efficient Installation​​: Secured with a single M6 hex wrench, reducing assembly complexity.
  5. ​​Load-Bearing Reinforcement​​: Enhances structural stability for applications requiring dynamic or heavy loads.

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.
