Product Overview

FRP Grating Clips & Accessories

Secure grating is safe grating. ZeAllgrate supplies a complete range of FRP and stainless clips, screws, washers and accessories engineered for quick, vibration-resistant grating installation on steel or FRP supports.

Available worldwide as fiberglass grating clamps — in British English, fibreglass grating clamps — the range doubles as grating retaining clips for molded and pultruded panels, with wholesale pricing for distributors, contractors and OEM projects.

  • Molded G-clips & S-clips for 25–50 mm grating
  • Stainless steel screw & washer sets (SS304/316)
  • FRP flat bar for clamping and edging
  • Expansion bolt kits for concrete supports
  • Anti-theft and lockable clip options
  • Bulk packaging for projects

Our engineers prepare a written resin recommendation with every quotation — matched to your media, concentration and service temperature.

Installation

Installation Notes

✂

Cutting

Carbide-tipped or abrasive cutters; support both sides of the cut; wear dust protection. Wet cutting recommended.

🔩

Fastening

Fasten every panel at every support intersection. SS304/316 G-clips in corrosive service; expansion bolts for concrete.

↔

Orientation

Pultruded bearing bars run across the span — never parallel. Leave thermal gaps at fixed supports.

Installation ParameterRecommended PracticeStandard Reference
Support SpacingMaximum span per certified load chart — never exceed recommended clear spanLoad chart per configuration
BearingMinimum 40 mm bearing on each supportZeAllgrate practice / ISO 14122-3
Fastener SpacingMinimum 2 hold-down clips per support beam, spaced ≤ 1219 mm (4 ft) on centre; minimum 4 clips per panelPer ZeAllgrate engineering practice
Thermal ExpansionAllow 3 – 5 mm expansion gap at fixed supports; molded coefficient ≈ 15–25×10⁻⁶ /°C (direction dependent)Manufacturer data
Cut HolesSeal cut edges in chemical service with resin; radius corners to avoid stress pointsDesign guide
Fall ProtectionHandrail height ≥ 1100 mm (ISO 14122-3) / 42 in (OSHA 1910.23); kickplate where requiredOSHA 1910 / ISO 14122

Resin Systems

Choose the Right Resin for Your Environment

Corrosion resistance starts with the resin system. ZeAllgrate offers 3+ engineered resin systems for every chemical environment.

Isophthalic PolyesterGeneral-purpose corrosion resistance; excellent value for industrial and water/wastewater applications
Vinyl EsterSuperior chemical resistance to acids, alkalis and solvents — for chemical plants and bleaching environments
PhenolicLow smoke, low flame spread and high-temperature performance — for fire-critical and offshore applications
Fire-Retardant (FR)Enhanced flame-retardant grades meeting surface-burning requirements (ASTM E84)
UV-StabilizedUV-inhibited formulations for outdoor and solar-exposed installations

Contact our engineers for a chemical-resistance recommendation matched to your specific media, concentration and temperature.

Selection Process

How to Specify in Four Steps

1

Define Environment

Identify chemicals, temperature, UV exposure and load requirements.

2

Choose Grating Type

Molded for bi-directional strength; pultruded for long spans and heavy loads.

3

Check Load / Span

Verify the support span against certified load charts for your configuration.

4

Specify Surface & Clips

Grit-top for wet areas; SS304/316 clips for secure fastening.
