SCH38/25C IFR ST CH

Product catalog summary

Material Specifications
The document describes a polyester self-extinguishing resin reinforced with roving glass fiber type 'E'. It includes inorganic fillers without halogens and is produced using RTM resin transfer moulding technology. The standard followed is DIN 24537-3.

Product Description
The grating type is SCH38/25C IFR ST CH with dimensions of 38x38 mm. It features a covered group linear standard mesh with a main mesh height of 28 mm and additional parts with varying thicknesses. The standard finishing is a moulded covered drop style with an antiskid level of R10 V4 according to DIN 51130. The weight is 19 Kg/m².

Standard Panels and Colors
Panels are available in sizes 1000x2000 mm, 1220x3660 mm, and 1000x4038 mm, all in grey RAL 7004. The panel's bearing direction is both, with tolerances of ± 5 mm for panel dimensions, +2/-2 mm for height, and +/- 6% for weight.

Electrical Properties
The material is an excellent insulator with very low current absorption. It complies with norms EN 61340-2.3, IEC 61340-4-5, and ASTM D 149-97a.

Ageing Resistance
The product has passed ageing tests with UV lamps according to ASTM G154-06, showing no evident defects after exposure to heat, cold, and humidity cycles as per UNI EN ISO 9142/04.

Fire and Smoke Properties
The product is fire retardant with a classification of Bfl-s1 according to EN 13501-1 and complies with smoke density and toxicity norms AFNOR NF16-101F1.

Load and Bearing Capacity
The document provides detailed tables on accidental loads and deflection conditions based on support distances. It emphasizes the need for compressive strength verification under heavy-duty loads.

Safety and Environmental Considerations
The conversion safety factor varies based on exposure conditions: 0.75 for internal, 0.65 for external, and 0.50 for aggressive conditions. Chemical resistance should always be verified with the technical department.
