Chemical Resistance Reference
Indicative chemical resistance by resin system — the basis of every material selection. Always confirm the final recommendation against our certified chemical resistance guide for your specific media, concentration and temperature.
| Medium | FRP Clip | SS304 | SS316 |
|---|---|---|---|
| Chemical service | Good (UV-stabilized) | Good | Excellent |
| Seawater | Good | Fair (pitting) | Excellent |
| Chlorides / Bleach | Excellent | Fair | Excellent |
| Acid service | Good | Good | Excellent |
| UV exposure | Excellent (stabilized) | Excellent | Excellent |
Ratings: Excellent — long-term service; Good — suitable with normal inspection; Fair — limited service, verify application. Full Chemical Resistance Guide →
Ten Resin Systems for Every Chemical Environment
Corrosion resistance starts with the resin. ZeAllgrate manufactures in ten engineered resin systems, matching the industry’s proven material selection methodology.
| Resin System | Key Property | Max Service Temp | Typical Use |
|---|---|---|---|
| Isophthalic Polyester (ISO) | General corrosion resistance | 60 – 70 °C | Water/wastewater, industrial floors |
| ISO Chemical Grade | Enhanced chemical resistance | 70 – 80 °C | Chemical plant walkways |
| Vinyl Ester (VE) | Superior acid/alkali/solvent resistance | 80 – 90 °C | Chemical, bleaching, pulp |
| VE Chemical Grade | Maximum corrosion performance | 90 – 100 °C | Harshest chemical exposure |
| Phenolic | Low smoke, low flame spread | 120 – 150 °C | Offshore, fire-critical |
| Fire Retardant (FR) | ASTM E84 Class A, flame spread ≤ 25 | 60 – 70 °C | Code-required flame ratings |
| UV-Stabilized | Outdoor UV resistance | 60 – 70 °C | Solar-exposed installations |
| Heat Resistant | High-temperature service | 100 – 120 °C | Process heat areas |

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 Parameter | Recommended Practice | Standard Reference |
|---|---|---|
| Support Spacing | Maximum span per certified load chart — never exceed recommended clear span | Load chart per configuration |
| Bearing | Minimum 40 mm bearing on each support | ZeAllgrate practice / ISO 14122-3 |
| Fastener Spacing | Minimum 2 hold-down clips per support beam, spaced ≤ 1219 mm (4 ft) on centre; minimum 4 clips per panel | Per ZeAllgrate engineering practice |
| Thermal Expansion | Allow 3 – 5 mm expansion gap at fixed supports; molded coefficient ≈ 15–25×10⁻⁶ /°C (direction dependent) | Manufacturer data |
| Cut Holes | Seal cut edges in chemical service with resin; radius corners to avoid stress points | Design guide |
| Fall Protection | Handrail height ≥ 1100 mm (ISO 14122-3) / 42 in (OSHA 1910.23); kickplate where required | OSHA 1910 / ISO 14122 |
Choose the Right Resin for Your Environment
Corrosion resistance starts with the resin system. ZeAllgrate offers 3+ engineered resin systems for every chemical environment.

| Phenolic | Low 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-Stabilized | UV-inhibited formulations for outdoor and solar-exposed installations |

How to Specify in Four Steps
Define Environment
Identify chemicals, temperature, UV exposure and load requirements.
Choose Grating Type
Molded for bi-directional strength; pultruded for long spans and heavy loads.
Check Load / Span
Verify the support span against certified load charts for your configuration.
Specify Surface & Clips
Grit-top for wet areas; SS304/316 clips for secure fastening.
