Application FAQ

Expert answers for common automotive bumper beams engineering queries.

Is it as safe as steel?

Yes, composite bumper beams are calculated to meet or exceed NCAP crash safety standards.

Can it be painted?

Beams are typically hidden, but our SMC is Class-A paintable if used for exterior styling.
