Metal Joints for Lean Production
Metal pipe joints are essential components designed to connect φ28mm lean pipes, ensuring strong and flexible structural assembly. These metal joints for pipes feature a dovetail interlocking design, where two joint pieces securely clamp the pipe using an M6 screw and nut. The surface is treated with electrophoresis, zinc plating, or chrome plating, providing superior rust resistance, wear resistance, and extended service life.
Enhanced Production Flexibility | Easily reconfigure and adjust structures as needed.
Improved Structural Stability | High load-bearing capacity ensures durability.
Increased Assembly Efficiency | Simple, tool-assisted installation for quick setup.
Superior Durability & Corrosion Resistance | Long-lasting metal pipe connector joints withstand industrial environments.
Selecting the right metal joints for pipes depends on the operational environment and industry requirements. Below are recommended options based on different conditions:
- Coastal & Island Regions
Recommended: Black electrophoresis metal joints for racks + inner anti-rust coated lean pipes.
We recommend this because:
The black electrophoresis metal pipe joint is coated with a protective black paint, which offers excellent corrosion resistance. When paired with lean pipes featuring an internal anti-rust coating, it provides enhanced durability and protection against the high-salinity conditions found in coastal and island environments.
- Tropical Rainforest Climates
Recommended: Black electrophoresis pipe connector metal + inner anti-rust coated lean pipes.
We recommend this because:
High humidity levels accelerate metal corrosion. The black electrophoresis layer and internal anti-rust coating significantly improve moisture resistance.
- Industries with Chemical Exposure (Textile, Chemical, Automotive, Military, etc.)
Recommended: Black electrophoresis metal joints + anti-rust ABS lean pipes.
We recommend this because:
These industries generate oil residues and chemical exposure. ABS lean pipes offer superior chemical resistance, strength, and wear resistance, making them ideal for harsh environments.
- Anti-Static Environments
Recommended: Anti-static metal joint supplies (zinc/nickel/chrome plated) + anti-static lean pipes or stainless steel pipes.
We recommend this because:
Anti-static lean pipes contain conductive plastic coatings, directing static electricity safely to the ground (conductivity value: 10⁶ to 10⁹ Ω). The plated layers on metal joints for pipes also enhance conductivity, ensuring a controlled electrostatic discharge environment.
- High-Temperature Environments
Recommended: Stainless steel pipes + metal pipe joints with zinc/nickel/chrome plating.
We recommend this because:
Zinc, nickel, or chrome-plated metal pipe connector joints offer excellent heat resistance, maintaining structural integrity under prolonged high temperatures.

- What types of metal joints are available?
We provide corner joints, three-way joints, four-way joints, and T-Type joints, etc.
Options include fixed-angle joints and adjustable-angle joints.
- What is the load-bearing capacity of your metal joints?
We provide detailed load capacity data upon request.
- Do you offer custom metal joints?
Yes, we support customized metal joints based on client specifications and drawings.
- What is your minimum order quantity (MOQ)?
Contact us for MOQ details based on product type and customization needs.
- What surface treatments do your metal pipe joints have?
Available finishes include electrophoresis, zinc plating, and chrome plating for enhanced corrosion resistance.
- How do I install metal pipe joints?
Installation is weld-free, using M6*25 screws and nuts.
