Expanded metal sheets (5) are used to produce tubular filters (13). The filters (13) have a central bore, a substantially cylindrical outer surface (25), and substantially flat end sections (31) which extend between the central bore and the substantially cylindrical outer surface. The filters (13) also include rounded corners (27) produced by a point loading process. Among other things, the filters can be used in automobile airbag inflators to capture slag (21) and absorb heat produced by the inflator's explosive charge.
