Bigger specs aren't always better—first consider the use case and the testing basis

PP interlocking flooring must be evaluated by combining dimensions, weight, locking system, ball rebound, slip resistance, and shock absorption together. Priority criteria differ entirely for school basketball courts, kindergartens, go-kart tracks, and event venues.

25–50 cmDimensions affect seam density, patterning, and localized repairs
115–750 gSingle-tile weight should be judged together with structural density and format
LockThe Key to Temperature Swings, Large Venues, and Long-Term Unlocking Risk
R10 / ≥95%Anti-Slip, ball rebound, and impact absorption must be balanced according to the scenario
When reviewing a spec sheet, first ask "what performance does this application need," then cross-check the test report, product manual, and project delivery configuration.
Short answer:The key specifications of PP interlocking sports flooring include 7 parameters: size, single-tile weight, thickness, snap-lock type, ball rebound rate, impact absorption, anti-slip coefficient. Reading specs isn't just about which number is bigger; you have to factor inUse CasesAssessment: a basketball court needs ball rebound ≥ 95% + moderate shock absorption; a kindergarten needs shock absorption ≥ 50% + anti-slip R10; a competition venue needs iBoost shock damping.Standard version parameters are subject to the test report of the actual model。

Practical meaning of 7 core parameters

1. Size (25×25 / 30.5×30.5 / 40×40 / 50×50 cm)

Large formats (50×50cm) have fewer seams and look close to a single continuous floor, suiting large venues; small formats (25×25cm) offer flexible patterning and easy transport, suiting small and irregular-shaped venues.

2. Single tile weight (115g – 750g)

Weight directly correlates with structural density and load-bearing capacity. Generally: 100–200g suits kindergartens/indoor use; 200–400g suits general-purpose courts; above 500g are the oversized jumbo models, with load-bearing of 1500kg+.

3. Thickness (13–25mm)

13–17mm is the standard thickness, suitable for most applications. 19–25mm is the thickened version, suitable for high-fall zones and heavy-load areas.Thicker is not better, while excessive thickness actually affects ball feel.

4. Snap-lock type (8-point / 16-point / soft connection)

The more lock points, the tighter the engagement. 8 points suit general courts; 16 points suit regions with large temperature variations (the North, the Northwest); soft connections (rubber joints) suit competition courts that require elasticity.

5. Ball rebound rate (≥ 90%–95%)

Core parameter for basketball projects. National standard baseline 90%, professional courts ≥ 95%, competition-grade ≥ 98%.Rebound rate isn't important for kindergarten facilities—impact absorption matters more。

6. Impact absorption (25%–80%)

Cushioning performance. Sports courts 25–55% (cannot be too soft, which affects ball feel); kindergarten activity areas 50–70%; high fall zones (slide landings) 70–80%.

7. Anti-slip coefficient (BPN / R rating)

BPN (British Pendulum Number) >= 47 is the national standard baseline; R-rating (DIN 51130) R10 is the common requirement for public venues - AnchorCare INTER-STELLAR achieves R10.

How to read a test report

A qualified sports flooring test report should include:

  1. Testing institution: CNAS + CMA dual marks
  2. Report number: Can be verified on the institution's official website
  3. Product model: matching the procurement contract word for word
  4. Test items: 18 harmful substances + 6 physical properties + odor grade
  5. Test results: Each item ≤ limit / meets standard
  6. Report date: Recommended within 2 years

Different scenarios call for different parameters:For campus venues, prioritize checking GB 36246，For sports venues, prioritize the balance of ball rebound + impact absorption。

FAQ

How to Choose Among AnchorCare's 14 Products?

By scenario: large campus venues use ANK2F four-grid / ANK5 jumbo; kindergartens use ANK4 clover / SVS1 Polaris; professional events use Quantum Stack / Interstellar; corridors with uneven bases use ANK6 jumbo copper-coin grid; exports to Europe and the US use ANK3 double-layer diamond 1-inch. For specifics, add us on WeChat to consult.

Which is stricter, the national standard or the European standard?

It varies by project. China's GB 36246-2018 covers more campus-ground hazardous substances (18 items) than Europe's EN 14904 (≥10 items); EN 14904 sets higher thresholds for sports-performance indicators (ball rebound / shock absorption) than the GB/T 19851 recommended standard. For projects exported to Europe, use ANK3 double-layer diamond (which passes both standards).

How do you tell recycled material from virgin material?

Virgin modified PP: uniform color, smooth surface, no obvious pungent odor when burned, crisp rebound. Recycled material: mixed colors, surface bubbles or impurities, acrid odor when burned, dull rebound. The professional way is to check Raw Material Purchase Invoices or Submit for PAHs / heavy metals testing。

What is the difference between iBoost damping shock absorption and conventional shock absorption?

iBoost is AnchorCare's proprietary true three-layer shock absorption system (hard top layer + elastic middle layer + cushioned base layer), delivering +30% impact absorption and +50% deformation resistance vs. single-layer structures. QUANTUM STACK is recommended for professional basketball courts, campus tracks, and premium walkways.

What does Anti-Slip granule anti-slip reaching R10 rating mean?

DIN 51130 classifies slip resistance in five grades from R9 to R13; R10 is the standard requirement for public buildings (schools, hospitals, shopping centers) and provides slip resistance in both dry and wet conditions. INTER-STELLAR's dimple-dot design achieves R10, with +100% friction vs. standard tiles in dry and wet conditions - ideal for poolside, corridors, and wet-area walkways.
