Product Advantages

Perfect Match with Your Cell Design: Each board is custom-cut to align with cell top and busbar configuration, avoiding gaps and sagging.

Protective & Durable: High chemical resistance ensures long-term use even in acid mist-heavy atmospheres.

Easy Maintenance Access: Modular structure allows workers to remove panels easily for inspection or maintenance.

Safety First: Anti-slip surface and insulation properties help prevent slips and electrical accidents.

Smart Busbar Support: Our design allows for partial load-bearing, helping to stabilize busbar layout and spacing.

Our After-Sales Service

Information We Need from You:

◎ Cell top layout or drawings

◎ Desired material and thickness

◎ Load-bearing or non-load-bearing requirement

We Solve These Common Concerns:

◎ Deformation over time? We use ribbed structures and high-grade resins to resist bending.

◎ Gap between board and busbar? We add recesses or cutouts for a flush fit.

◎ Installation confusion? We provide layout diagrams and pre-labeled panels.

Packaging & Transportation

Capping boards are shrink-wrapped and stacked on reinforced pallets or steel frames. Fragile corners are protected with foam or rubber guards.
We can combine shipment with other components (like cells, plates, busbars) to maximize container space and reduce shipping costs.
