9. Professional FAQ for FRP Micro Mesh Grating & Related Terms

Q1: What is the main difference between FRP platform grating and FRP micro mesh grating?

A1: The key difference lies in mesh aperture. FRP micro mesh grating is produced with a small mesh size (typically 12.7mm or less) to prevent the fall-through of small items or tools; FRP platform grating utilizes larger mesh openings (e.g., 38x38mm), designed to support personnel and equipment on platforms, walkways, and trenches.

Q2: What resin systems are recommended for high chemical/corrosion environments?

A2: Vinyl Ester or Phenolic resins are ideal for harsh chemicals. These resins surpass ISO 178 impact/flexural standards, delivering up to 50-year service cycles in acid/alkali atmospheres.

Q3: Does FRP protruded grating have advantages over molded types?

A3: Yes, FRP protruded grating exhibits higher unidirectional strength, better deflection resistance, and supports larger spans, making it suitable for heavy-duty or vehicular applications, in compliance with EN 13706.

Q4: What installation standards should be observed?

A4: Panels should be fixed per ANSI/NAAMM MBG 531-14 standards with stainless clips; always leave 5–8mm expansion gaps. All grating should bear ISO9001 and EN13706 mark for safety assurance.

Q5: What load and slip safety standards do these products meet?

A5: All frp micro mesh grating is tested to ASTM E84 (fire), ASTM D635 (flammability), EN 13706 (load/deflection), with slip surface conforming to R13 (DIN 51130) for maximum safety.

Q6: How to select the right thickness and panel size?

A6: Select based on span, load, and environment. For walkways, 25–38mm thick panels are standard; micro mesh may be installed for anti-drop risks. Always follow supplier load tables and field load testing data.

Q7: Can I order custom logo/color grating and ensure traceability?

A7: Yes. ZJComposites and other leading firms provide color coding, laser logo imprinting, and full barcode traceability to ISO 9001 standards for asset management or offshore regulation.
