Gun Roving
Basalt Continuous Filaments under the name of Basfiber®
General Description:
Gun-roving or spray-up roving is originally assembled basalt roving drawn with special sizing which make roving more rigid. Spray-up roving is specially designed to achieve excellent performance with polyester and vinyl ester resin spray up systems.

Nomenclature
Our nomenclature is based on three letter followed by three numbers split by dot and dashes.
Example:RGN-13.1200-11
The first letter will be always R which stands for our Rovings products. The following letters AS - GN - DR represent the roving type:
AS - Assembled Roving: External unwinding bobbin roving with on a tube or Internal unwinding (tubeless).
GN - Gun Roving: Internal unwinding (tubeless)
DR - Direct Roving: Direct Unwinding -
Tex Info
Tex of Gun roving is determined by:
- Fiber's monofilament diameter;
- Number of monofilaments in strand (i.e. number of nozzles in bushing);
- Number of strands in Gun roving which is limited by number of places at the creel and acceptable level of catenary which is getting worse with increasing of number of strands in Gun roving.
In our opinion, it is not wisely to use Gun roving which consist of more than 10 strands assembled together. Mechanical tests show 30% difference of tensile strength between Gun rovings consisting of 4 and 20 strands due to increased catenary.
