Technical Insight:

Thicker correx provides higher compressive strength but increases cost and reduces flexibility. The optimal choice balances durability and handling efficiency.

2. Density and Weight per Square Meter

Density directly impacts durability and load-bearing capacity.

Key Considerations:

• Low-density correx: More flexible but less durable
• High-density correx: Stronger, more resistant to puncture and deformation

Recommended Use Cases:

• Low density → Temporary short-term protection
• Medium density → Standard building renovation
• High density → Industrial flooring, logistics warehouses

Professionals often evaluate floor protection correx by grams per square meter (GSM), which typically ranges from 200gsm to 1000gsm depending on grade.

3. Surface Treatment Options

Modern floor protection correx can include various surface enhancements.

Common Types:

• Smooth surface: Easy cleaning, ideal for painting jobs
• Anti-slip textured surface: Reduces accident risk in wet conditions
• Laminated surface: Extra protection against chemicals and abrasion

Selection Guide:

• Painting & decorating → smooth surface
• Wet construction sites → anti-slip
• Heavy-duty renovation → laminated or reinforced surfaces

4. Load-Bearing Capacity

Load-bearing capacity is essential for protecting finished flooring such as:

• Hardwood
• Marble
• Vinyl
• Epoxy flooring

Factors Affecting Load Capacity:

• Sheet thickness
• Flute structure design
• Material density
• Installation method (taped seams vs loose lay)

Practical Recommendation:

For projects involving scaffolding or machinery movement, always choose reinforced floor protection correx with high compressive resistance.

5. Fire Retardant Grade

In commercial and industrial construction, fire safety compliance is often mandatory.

Options Available:

• Standard PP correx (non-fire-rated)
• Flame-retardant correx (FR grade)

When to Use Flame-Retardant:

• Shopping malls
• Airports
• Hospitals
• High-rise interior projects

Fire-rated correx is typically treated with additives that reduce flame spread and smoke emission.

6. Waterproof and Chemical Resistance
