CleanRoom Floor Manufacturers

Simply put, cleanroom flooring is a flooring system specifically designed for cleanrooms or dust-free workshops. Its primary objective is not aesthetics, but rather low particle generation, ease of cleaning, chemical resistance, and compatibility with overall cleanliness control.

Unlike standard epoxy or concrete flooring, professional cleanroom flooring minimizes seams and voids to prevent dust and microorganisms from accumulating in crevices.

Additionally, selecting the right cleanroom flooring requires considering factors such as equipment vibration, electrostatic discharge (ESD) properties, and load-bearing requirements.

Cleanroom engineering brands like Deiiang typically recommend specific flooring solutions based on the industry—such as semiconductors, pharmaceuticals, or biological laboratories—offering options like cleanroom epoxy flooring, ESD flooring, or systems integrated with raised floors.

Common types of cleanroom flooring include:

Cleanroom epoxy flooring

Advantages: Seamless, dense surface, easy to clean, cost-effective

Applications: Electronics, food processing, pharmaceutical plants, medical device assembly workshops, etc.

ESD flooring (Anti-static / Conductive flooring)

Advantages: Safely dissipates static electricity, protecting precision electronic components

Applications: Semiconductor facilities, chip packaging and testing, electronics assembly, precision instrument workshops

Advantages: Comfortable underfoot, low noise, wide range of designs; available in specialized cleanroom-grade and conductive PVC versions

Applications: Hospital operating rooms, pharmaceutical clean zones, medical laboratories

Raised floor systems

Advantages: Allows for routing of cables, airflow, and piping underneath; facilitates maintenance and spatial reconfiguration

Applications: Data centers, ISO Class 1–5 cleanrooms, semiconductor cleanrooms, and environments requiring extensive utility routing

When selecting the flooring type, the initial considerations typically include industry standards, cleanliness classification, static control requirements, and the budget; these factors determine whether to choose cleanroom epoxy flooring, ESD flooring, PVC flooring, or a system solution incorporating a raised floor.

The surface should be smooth, level, easy to clean, and resistant to dust accumulation (refer to the ISO 14644 series and GMP standards regarding the cleanability of construction materials and the prevention of particle generation).

For facilities such as pharmaceutical and food processing plants, both China’s Good Manufacturing Practice (GMP) and WHO GMP emphasize that flooring in clean areas must be corrosion-resistant, easy to clean, and free from particle shedding.

The fundamental difference lies in their anti-static capabilities:

Standard cleanroom flooring: Characterized by low particle generation and ease of cleaning, with no specific requirements regarding static electricity.

ESD flooring: While meeting cleanroom performance standards, it incorporates features such as conductive aggregates, conductive copper foil, and grounding systems to safely dissipate static electricity generated by personnel and equipment.

Generally, ESD flooring is recommended—or required—in the following scenarios:

Production lines for semiconductors, chips, LEDs, and LCDs; precision electronics assembly; explosion-proof zones; and facilities processing components susceptible to electrostatic discharge (ESD) damage.

For specific resistance ranges and testing methods, please refer to industry standards such as ANSI/ESD S20.20 and the IEC 61340 series.

When designing ESD cleanroom flooring, Deiiang determines the system resistance range and establishes design specifications and installation plans in accordance with these international and industry standards.

Deiiang does not simply provide "flooring"; we deliver comprehensive cleanroom flooring systems designed for total environmental control within the cleanroom.Compared to standard flooring companies, we differ in several key ways:

We possess deep expertise in cleanrooms—not just flooring. When designing our flooring systems, we consider factors such as air cleanliness (referencing ISO 14644, China GMP, and WHO GMP standards), process workflows, pressure differential control, and personnel/material logistics, rather than focusing solely on surface flatness or thickness.

We offer integrated design solutions covering a wide range of options—from cleanroom epoxy and ESD flooring to clean-grade PVC and raised flooring systems—rather than simply pushing a single type of material.

Upon completion of the flooring installation, we coordinate with third-party agencies to conduct tests on flatness, adhesion, and electrostatic performance, providing the necessary data to support subsequent cleanroom validation (such as ISO 14644-1 particle testing).

In short, Deiiang’s advantage lies in providing professional, engineered cleanroom flooring solutions, rather than merely selling coatings or flooring materials.

Answer: The standard process generally consists of six steps, outlined briefly below:

Substrate Preparation

Grinding and vacuuming; repairing hollow spots and cracks to ensure the floor is dry, solid, and level.

Applying Penetrating Primer

Sealing the floor with epoxy primer to enhance adhesion and reduce the risk of dusting or blistering.

Intermediate Leveling Coat

Applying an epoxy intermediate coat mixed with quartz sand or powder; troweling to level the surface and increase strength and thickness.

Fine Leveling / Putty Layer

Using epoxy putty to fill pinholes and minor irregularities, creating a smooth base for the topcoat.

Topcoat Application

Applying the epoxy topcoat via rolling or troweling to achieve the final color and finish; for ESD flooring, the conductive layer and grounding system are installed at this stage.

Curing and Maintenance

Allowing the floor to cure naturally; foot traffic and heavy loads are prohibited for 24–72 hours, and the floor is ready for normal use only after curing is complete.
