Flat Wire Belt: Direct‑Welded Edge Vs Clinched Edge
Aug 28, 2026
Edge treatment is critical for Flat Wire belts, as it directly impacts load‑bearing capacity and service life.
Two mainstream edge configurations are available: direct‑welded edges and clinched edges. They suit different working conditions. Selection shall be determined based on conveyed materials and site conditions.
1. Direct‑Welded Edge
Edges are fixed by welding for high structural integrity, the most common edge style for Flat Wire belts.
High robustness: Excellent overall edge performance, ideal for heavy‑duty applications with high load requirements.
Cost‑effective: Less manufacturing labor compared with hook‑type version, lower production cost and competitive end‑user price.
2. Clinched Edge
Edges are assembled with hook structures, focusing on easy maintenance and operational safety.
Easy self‑repair & replacement: Sections of the belt can be replaced on‑site under manufacturer guidance.
No hot‑work required: No welding or cutting during installation and replacement; no spark generation. Suitable for hot‑work‑prohibited workshops, e.g. food, pharmaceutical and dust‑risk environments.

4. Additional Purchase Considerations
- Material Selection
Edges cut from sheet metal may have burrs and poor flatness, risking scratches to conveyed goods. Specially processed materials deliver smooth burr‑free surfaces at higher material cost.
- Pitch Accuracy
Great‑wall mesh belts are mostly gear‑driven. Consistent pitch is essential for smooth conveying. Products processed by fully‑automatic production equipment are recommended.
- Sprocket Compatibility
Mesh belt specifications must strictly match mating sprocket to prevent gear‑sticking and ensure stable operation.
Service life and running performance of Flat Wire belts largely depend on details such as edge finishing and pitch tolerance.
KTK manufactures flat spiral wires on imported automatic machinery with tight mesh dimension control. Raw round wires are processed by special forming technology to achieve burr‑free smooth edges and smooth conveying performance.
