Cleanroom Coving
& Cove Skirting
Systems
The seamless, radiused junction between walls, floors, and ceilings is not merely cosmetic — it is a critical hygiene engineering control. Metrolabs supplies and installs professional-grade cleanroom coving systems that eliminate particle and microbial harbourage points at every junction in your facility.
The Science Behind the Curved Junction
A right-angle corner between two surfaces is the single most problematic area in any laboratory or cleanroom — it is impossible to clean effectively, impossible to decontaminate completely, and a reliable harbour for both particulate matter and microbial contamination.
Why Right Angles Fail
Mops, cloths, and cleaning equipment cannot reach into a 90° corner. Particles accumulate and microbial biofilms form in the unreachable angle — compromising GMP compliance and contamination control protocols.
How Coving Solves This
A radiused cove — typically 50 to 150 mm radius — replaces the right angle with a smooth curve that can be completely cleaned by a standard mop or wipe. No hiding place for particles or microbes.
Required by Regulatory Standards
Coved junctions are explicitly required or strongly recommended by GMP guidelines (WHO, EU, US-FDA), ISO 14644 cleanroom standards, NABL accreditation protocols, and pharmaceutical facility inspectors.
Where Coving Is Applied
Wall-to-floor junctions (most critical), wall-to-wall internal corners, wall-to-ceiling junctions, column bases, doorframe bases, and around all floor penetrations including drain points.
Six Coving & Cove Skirting Systems for Every Application
Metrolabs supplies and installs the full range of cleanroom coving systems — matched to your facility’s chemical exposure, cleanliness class, and budget:
PVC Cove Skirting (Pre-Formed)
Factory-formed PVC coving in standard radii (R50, R75, R100, R150). The most economical coving solution for ISO Class 7–8 cleanrooms, pharmaceutical labs, and healthcare facilities. Installed using waterproof adhesive and sealed with matching sealant for a continuous hygienic junction.
Epoxy Cove Skirting (Formed In-Situ)
Site-applied epoxy mortar coving formed by skilled applicators to create a fully monolithic, seamless junction with the floor. Bonds integrally with the epoxy floor system — no joint, no sealant line. The industry standard for ISO Class 5–7 pharmaceutical cleanrooms and aggressive chemical environments.
Stainless Steel Cove Skirting (SS 316L)
Precision-formed Grade 316L stainless steel cove skirting for ultra-critical environments — surgical suites, injectable drug manufacturing, and high-sterility research facilities. Fully weldable to adjacent SS wall and floor panels for a truly seamless, electro-polished surface resistant to all disinfectants.
GRP / FRP Cove Skirting
Glass Reinforced Plastic coving for environments requiring a lightweight, highly chemical-resistant, non-metallic solution. Popular in food processing facilities, chemical labs, and marine environments where stainless steel is impractical and PVC lacks chemical resistance.
Antifungal & Antimicrobial Coving
Specially formulated PVC or epoxy coving incorporating silver-ion antimicrobial additives. Provides an additional layer of protection in high-risk microbiology labs, hospital isolation rooms, and biosafety facilities where surface-resident microbial contamination is a persistent risk.
Flexible Vinyl Cove Skirting
Heat-welded flexible vinyl coving for use with vinyl sheet flooring systems. Provides a continuous, welded junction that eliminates the seam between floor and wall covering — popular in hospital corridors, diagnostic labs, and cleanroom anteroom environments.
Coving Is Required by Every Major Cleanroom Standard
WHO / EU GMP Guidelines
WHO Good Manufacturing Practice and EU Annex 1 guidelines for sterile pharmaceutical production explicitly specify coved junctions to eliminate contamination harbourage.
WHO GMP · EU Annex 1ISO 14644 Cleanroom Standard
ISO 14644-4 (Design and Construction) specifies that cleanroom surfaces must be smooth, non-shedding, and free of crevices — coved junctions are the standard engineering solution.
ISO 14644-4NABL Accreditation
NABL laboratory assessment criteria require cleanroom and controlled environment facilities to demonstrate adequate contamination control — coved junctions are a fundamental visual compliance indicator.
NABL · ISO 17025FSSAI & FDA Compliance
Food Safety and Standards Authority of India (FSSAI) and US-FDA cGMP guidelines for food and drug manufacturing require hygienic design of all surfaces including wall-floor junctions in production areas.
FSSAI · US-FDA cGMPPrecision-Selected Materials for Every Environment
Metrolabs selects the coving material based on your facility’s cleanliness class, chemical exposure, cleaning protocol, and regulatory requirement:
PVC (Polyvinyl Chloride)
The most widely used coving material. Pre-formed, lightweight, easy to install, and resistant to most standard cleaning and disinfection agents. Available in white, off-white, and grey. Recommended for ISO Class 7–8 facilities.
Epoxy Mortar
Site-formed in-situ epoxy cove fully integrated with the epoxy floor system — creating a completely seamless, monolithic wall-floor junction with no sealant joint. Chemical-resistant to pH 2–12. Required for ISO Class 5–7 pharmaceutical cleanrooms.
Stainless Steel 316L
Precision-fabricated and electro-polished to Ra < 0.5 μm for ultra-critical sterile manufacturing. Fully weldable for a truly gapless junction. Resistant to all pharmaceutical disinfectants including oxidizing agents and VHP sterilization.
Professional Coving Installation — Step by Step
A structured, quality-controlled installation process ensures perfect adhesion, true radii, and a fully compliant hygienic junction:
Site Survey & Junction Assessment
We survey all wall-floor, wall-wall, and wall-ceiling junctions — identifying existing damage, contamination, and the coving system appropriate for your cleanliness class and chemical regime.
Surface Preparation
Existing sealants and old coving removed. Junction surfaces ground, cleaned, primed, and moisture-checked. All penetrations around pipes and conduits sealed prior to coving application.
Coving Application & Forming
PVC coving adhered with specialist contact adhesive. Epoxy cove mortar formed in-situ using radius templates to achieve consistent curvature. SS cove welded and electro-polished for seamless integration.
Sealing, Finishing & QC Inspection
All junctions sealed with flexible compatible sealant. Final inspection using radius gauges and gloss measurement. Compliance certificate issued against specified standard (GMP / ISO 14644 / NABL).
Coving Is Not a Finish — It Is a Hygiene Control
Eliminates All Dead Angles
Every right-angle corner in your facility — wall-to-floor, wall-to-wall, column bases, door frames — is replaced with a cleanable radius. No hiding place for particles, bacteria, or biofilm.
Turnkey Supply & Installation
Metrolabs supplies all coving materials and provides certified installation teams — handling surface preparation, forming, sealing, and post-installation inspection. One point of responsibility, from specification to compliance certificate.
Matched to Your Floor & Wall System
Our coving is selected to be fully compatible with your existing or planned floor system (epoxy, vinyl, resin) and wall cladding — ensuring chemical compatibility, thermal expansion matching, and adhesive bond integrity.
Compliance Documentation Provided
Every completed coving installation is supported by documentation suitable for GMP audits, NABL assessments, and ISO 14644 certification reviews — including material data sheets, installation records, and QC inspection reports.
