Impact Resistance: GRP (Glass Reinforced Plastic) housing withstands 50J+ mechanical shocks, far exceeding standard metal/plastic fixtures.
Zero Corrosion: Immune to saltwater, acids, and alkalis – ideal for offshore platforms, chemical plants, and coastal facilities.
Lightweight Yet Strong: 30% lighter than steel with comparable tensile strength, reducing installation strain.
Non-Conductive: Eliminates electrical risks in wet or conductive dust environments (e.g., coal mines).
Marine & Offshore: Oil rigs, shipyards (resists salt spray corrosion).
Chemical Processing: Battery plants, fertilizer production (endures H2SO4/NaOH exposure).
Wastewater Treatment: High humidity and H2S gas resistance.
Explosion Containment: GRP’s non-sparking properties prevent ignition of flammable gases/dusts.
Thermal Stability: Withstands -40°C to +120°C without warping or cracking.
Low Maintenance: No rust or degradation over time, even with frequent chemical washes.
| Parameter | GRP-Specific Advantages | Standard Specs |
|---|---|---|
| Material | GRP (Glass Reinforced Plastic) – UL94 V0 rated | GSP material (alternative option) |
| Impact Test | Passes IK10 (50J impact resistance) | IK08 (20J) for standard models |
| Corrosion Proof | 5,000-hour salt spray test (ISO 9227) compliant | Standard anti-corrosive coating |
| Weight | 2.1kg/m (BYS-600) vs. 3.4kg/m for steel equivalents | Lightweight aluminum alloy options |
| Thermal Range | -40°C to +120°C operational | -30°C to +60°C for standard housing |
vs. Aluminum: No galvanic corrosion risk when paired with stainless steel fixtures.
vs. Stainless Steel: 50% cost savings with equal chemical resistance.
vs. Plastic: 3x higher impact resistance and UV stability.
Certifications: ATEX/IECEx Zone 1 & 21 (GRP-specific ratings available).
Custom Colors: GRP can be dyed (e.g., yellow for hazard zones, gray for discreet installations).
Voltage: 100V–277V with dual insulation for extra safety.
