8. Professional FAQ: Covered Grating Technical Terms

1. What is the typical material composition of covered grating?

High-strength E-glass fiber roving combined with a resin matrix (options: isophthalic polyester, vinyl ester, phenolic). Anti-slip grit is usually embedded during molding for maximum adherence.

2. What panel thickness and load classes are available?

Standard thickness: 25mm—60mm.
Load classes: A15–F900kN (per EN 1433), ranging from pedestrian traffic to forklift/vehicle grades.

3. Which industry standards does your grating cover comply with?

Main compliance: ISO 9001:2015, ASTM F3059, EN ISO 14122-2, UL94 (flame), ASTM C1028 (slip resistance), FDA (food grade on request).

4. How is slip resistance tested and quantified?

By measuring the Coefficient of Friction (COF) with ASTM C1028 and EN 13893, with ≥0.75 considered anti-slip.

5. What is the recommended installation method for covered grating?

Fixing clips (M-type, C-type, L-type), bolting to steel beams, and edge banding for safety. Installation guide and layout drawing are supplied.

6. Can the product be used in high-temperature or fire-prone areas?

Yes, with fire-retardant resin selection and post-cured processing, covered grating passes UL94 V-0 and ASTM E84 Class 1.

7. What type of non-destructive testing & QC is performed?

Visual inspection, barcol hardness, flexural strength (ISO 14125), deflection testing, and UV/salt spray/cold cycling (ISO 4892/ASTM B117).
