System Modules & Components Overview
Coving System
In clean zones, Coving is the default. By combining inner/outer/double radii with bases and positioning connectors, wall-to-wall, wall-to-floor, and door-opening turns become flush, low-seam continuous seals—friendly for mopping and spray-down, audit-ready, and consistent with ISO 14644-4 principles on minimal seams and cleanability.

Components & Functions
KH50WY Outer Radius (R≈50)
Smooth outer-corner transition; often paired with a base to avoid dirt traps.
KH6401 Inner Radius
Rounds inner corners; seals in the same direction as the panel groove/gasket.
KH4514 Double Radius
Two-way turns for column edges/door jambs, keeping visual and hygienic continuity.
KH36LDZ Base
Plinth at wall-to-floor junction; receives inner/outer radii for easier mopping and drainage.
KHJH05 Positioning Piece
Short piece for positioning/fixing coving and base profiles.
KHJH3127 Positioning Connector
Alignment/connection to reinforce node integrity.
If your area is non-critical, space-constrained, or budget-sensitive, we can also provide Square Corner transitions, provided flushness and airtightness are maintained.
Selection & Installation Notes
- Confirm panel thickness / slot width / gasket series first, then match the profile; Pre-cut/Pre-drilled to reduce onsite dust and labor.
- Keep a unified radius (e.g., R50) for trolley passage and consistent appearance.
- Finishes: default Anodized; use Powder Coated for feature areas; evaluate ESD dissipative layer for electronics/semiconductor zones.
Square-Corner Transitions
With flushness and airtightness ensured, use square-corner profiles, right-angle pressure/snap-in strips, and end caps for a crisp look with smaller space claim. Selection tips: choose profiles by panel thickness/slot width/gasket; unify elevation with doors and the Adjustable Floor Guide; add gaskets where needed to avoid step joints. Recommendation: prefer coving in audit-sensitive zones; square corners are suitable for dry areas or where equipment abuts walls.
Wall / Partition Frames & Edge Trims
The wall-partition system consists of vertical posts/horizontal beams plus H/U trims, center H-Joiners, I-Joiners, floor/top guides and gaskets. The goal is to create flat, continuous, airtight surfaces at every node, supporting modular assembly and later replacement.
