GN2180 Edge Protection Seal Profiles
These edge protection seal profiles, GN 2180, can be used to seal doors, covers and hatches. The profiles are pressed by hand onto the front of metal sheets and plates. The embedded clamp insert prevents detachment and glue or other adhesives are not required.
They are installed on the edges of metal sheets and plates, to protect surfaces from damage caused by sharp edges. The edge finish additionally produces a decorative effect, while the need for potential further treatment such as burring and chamfering of cut or laser-cut metal sheets is reduced to an absolute minimum, cutting costs.
When assembled, the profile should deform slightly according to w2. This ensures an optimal seal. Adherence to the guideline placement radii (r1... r4) is recommended in order to ensure a tight profile seal and to make assembly easier.
The NBR profiles are recommended for use in cases where contact with fuels, oils or coolants can occur.
EPDM profiles are certified according to UL 50 and UL 94-HB and are therefore approved for the US-American and the Canadian market.
