3A (5B or 5C)

Load classes according to norm NF EN 12825
Safety factor = 2

OPTIONS

To regulate the air flow :
a damper (adjustable without removing panel) consisting of two corrosion protected perforated steel sheets, one fixe, the other sliding.

COVERINGS

The SEC 800 panel can be supplied with the following coverings :
laminate, vinyl, linoleum (textile excluded)

NB : A system classed 1A is a system which the ultimate load is at least 4 kN (load classe 1). The working load is at least 2 kN, with a safety factor of 2, for a deflection less than 2,5 mm (deflection class A).
