SCH38/25 CFR ST M

Product catalog summary

Material Specifications:
The grating is made from polyester resin that is self-extinguishing and conductive, reinforced with 'E' type roving glass fiber. It includes inorganic fillers without halogens and carbon black conductive powder. The production technology used is RTM resin transfer moulding, adhering to DIN 24537-3 standards.

Grating Design:
The grating features a square mesh design with a main mesh size of 31x31 mm, a clear span of 25 mm, and a height of 5 mm. The standard finishing is a concave 'Meniscus' type with an antiskid level of R13 V10 according to DIN 51130. The weight is 12 Kg/m².

Panel Specifications:
Standard panels are available in sizes 1000x2000 mm, 1220x3660 mm, 1000x4038 mm, and 1000x3000 mm, all in black RAL 9011. The panels can bear loads in both directions with a tolerance of ±5 mm in panel dimensions, +2/-2 mm in height, and ±6% in weight.

Electrical Properties:
The grating is an excellent conductor with surface resistivity and transversal electric resistance conforming to IEC standards. It also has excellent dielectric strength.

Ageing and Fire Resistance:
The grating has passed ageing tests with UV exposure and shows no defects after heat, cold, and humidity cycles. It is fire retardant with a classification of Bfl-s1 according to EN 13501-1 and meets smoke density and toxicity standards AFNOR NF16-101F1.

Load Bearing and Safety:
The document provides detailed tables on accidental loads and deflection limits. It emphasizes the need for compressive strength verification under heavy-duty loads and specifies conversion safety factors for different environmental exposure conditions.
